Technology has always enhanced and enriched our life. It has made everything very easy and convenient for us. We can say that this is only the primary goal of technology to improve our lives and make us free of the daily monotonous manual work by turning everything into digital.
We have experienced all the latest gadgets and gizmos and visualized the world in our hands. But we know how tough it becomes for the blind people in this world as they cannot even see the beauty of the nature or even experience having a cell phone in their hands with multiple features. They just cannot even see the TV or go to the movie theaters, work on computers, read newspapers and textbooks. Technological advancements like computers and Internet can help us a lot in means of viewing the latest information but what about the blind people? As we have heard of Braille method which helps the blind people to read and write but it does get so expensive and not so interesting.
But still technology has helped the visually impaired people also in its own way by providing Audio Books. Before we see how the Audio books have helped the blind people let us first see what is actually an Audio Book?
Audio Books mean the audio version of the book, a simply recording of verbal words but it is not actually a book.
They are the books which we can simply enjoy and learn by just listening to them and thus acted as the best source of learning for the blind people.
These books have the verbal words which are narrated by the professional narrators and actors. It has music built into it with lots of sound effects and thus it helps the blind people to hear stories and current news updates of their country.
Talking about the advantages of the Audio Books for the blind people is that:
Those blind people who had an interest in reading novels can now listen to it with interest and excitement.
Audio books come in the form of cassettes or CDs or DVDs which you all can easily get from the bookstore. But if you really need to use Internet then you can also download them which is really very inexpensive or sometimes even free. The downloadable audio books have made the life of blind people easy.
Apart from listening to stories or news the visually impaired can also learn vocabulary with pronunciation or learn other language with perfection.
It can be very helpful for the small kids who are blind by birth as they can listen to the bed time stories daily.
Thus we see how the Audio Books, a new hope for the blind by the technology, have enhanced their lives and given them the reason to live their life to the fullest.

What is SNMP?
It is a protocol for network management. SNMP is an acronym for standard Network Management Protocol. This protocol is used to collect information and configure different devices in the network system. The devices can be servers, printers and hubs on a network.
It was developed in 1988 to provide the TCP/IP protocols the monitoring capabilities. Later, in 1990s it was given the status of internet standard. Different versions are available. Some of them are- SNMPv1, SNMPv2c, SNMPv2 and SNMPv3. Today the network hardware comes with built in SNMP agents. You have to configure these agents to exchange information and communicate with the network management system.
Thus this protocol is used for network management. The network management systems use this protocol to communicate with the network elements. The network elements thus must have SNMP agent to make the communication possible. You can use SNMP to monitor the network, detect any faults and errors in the network. You can also use it to configure remote devices.
The network management software initiate a message called as SNMP GET while the network element initiate a message called as SNMP trap. The network management software receive message from the network elements as SNMP trap.
The basic components of SNMP are:
Network elements.
SNMP agent.
Network management system.
Agent helps in the transfer of the data to the network management system. Each SNMP agent has different job to perform. The information is send to the network management system which is also called as the control center. Network elements are the one which have the SNMP agents. The elements can be hubs, printers, routers, IP telephones and servers.
How SNMP works?
A network management system has different network elements. These network elements have SNMP agent. Data stream flows among these network elements. The SNMP agent provides the information as feedback to the main network system. This information is in the form of SNMP traps. This data gives the information of what is actually happening in the network. And this data stream is monitored by the network system.
The SNMP traps are first arranged and then they are filtered. The traps are first decoded by the management system. The filtering is on the basis of matching them to the event filters. The system takes the action on the basis of the type of event filters that match. The main network use SNMP GET to receive the data from the network element. It uses SMNP SET to alter the data and SNMP MIB to modify the data on hardware and software.

7 Significant Reasons To Use Computers In Your Classroom
Technology is all around us so why the classrooms in the schools should be left behind. But why should we use the technology in classrooms? The reasons can be divers but there are certain reasons as to why we should. They are:
Every student has a different level of IQ than the other. Some may be fast learners and some may grasp the things slowly. Some may just memorize the whole lecture instead of understanding while some go into too much of details. Thus there is a wide gap between the students sitting in the same room and studying the same course. The use of technology can bridge the gap between them.
The boring lectures can be made interesting by the use of the technology in the classes. The absenteeism and the class bunks can be reduced.
Implementing the technology helps the students to explore the actual use of the studies they are taking in the rooms. They can visualize how the technology is actually implemented in the real world and how they can enhance their knowledge further, what they need to learn more and the likes.
The students can find more data regarding the topics that they are studying that may be impossible to gather form other sources, save the files and make their own notes in the classroom by browsing the net and searching the websites. This data collected and saved as notes saves time and the money of the students.
The assignments given to the students can be taken up as class presentations. This not only develops the presentation skills of the students but also makes the whole study interesting and simultaneously grooms the personality of the students.
Interact with number of students simultaneously. The technology also provides one to one interaction among the professors and the students such that the professor can pay individual attention to the students in the class rooms. The students can also interact with the other students in other colleges and share their views on different topics.
The technology can be used to provide a simulation environment where the students can be given the problems and an environment that is similar to the real conditions. Thus the students get an opportunity to actually act in the situation. This makes the whole thing interesting and the students participate, come up with new ideas and actually gain knowledge of how to implement the theory into practice.
Thus the use of technology not only improves the interaction among the students, but also develops the team spirit among them, helps in developing the personality and thus the very objective of the education of developing the individual.

The Disadvantages of Mobile Phones
Every coin has two faces. Same goes with the mobile technology. It has numerous advantages but it also brings with it some disadvantages.
Effect on Health
One of it is the radiations of mobile phones that are causing serious health hazards to the users. The mobile phone users are more prone to brain tumors, ear defects, headaches and blurring of vision. The mobile phones use microwave radiations to transmit data or more clearly they use these radiations to connect. For this base stations are to be installed in various parts of the city so that effective coverage can be given to the users.
These microwaves lead to serious health problems. it can cause the damage to the DNA, a causative factor for mutation in species, eye vision getting blurred and eye cancer, infertility, hyperactivity in new born children and different type of damages to the ear and tympanic membrane which can cause hearing defects in the individuals who excessively use mobile.
Addiction in teenagers
Due to low priced services in the form of postpaid and prepaid the teenagers can easily avail mobile telephony. Here the benefits get converted to disadvantages when the device is over used every time and at every place. The teenagers are talking of the services, giving and receiving text messages; downloading wallpapers and ringtones and playing games. They by this way get detached with the other important activities which are so important for their social and personality development.
No personal life
You keep it with you all the time and everywhere. You take it with you in an important meeting. You are discussing an important aspect of the budget for approval. At this point the mobile beeps and you get distracted from the important thing that you were discussing. Take another situation. You are on a vacation and relaxing on beach. Just then the mobile vibrates and when you receive the call it is just another sales advertisement by the service company. It gets annoying at times. It is everywhere with you. Now you have to draw the line when to use it.
You just splurge money on it
You can’t avoid this situation. There are many features being added up almost everyday and you want your mobile to b a perfect one. So, you move to the market and reach the retail to get some latest features add on your set which you seldom use. This act heavy on your pocket at times and is just spending money on the thing that you don’t use.

What is Automotive Technology
Automotive technology is a very wide field which covers different type of specializations. It is an umbrella term which covers all the technology and the activities related to the cars and automobiles designing and construction. In more general terms we see the technicians and specialists who are designing the engines for car and truck. All of them are associated with the automotive industry and technology.
The auto specialist, auto technicians, repair design specialist and many more are devoting their time designing and repairing engines of cars and trucks and making the cars and trucks more efficient than before. In this way they are contributing to the automotive technology.
In ancient times there were carriages and carts pulled by the horses. Since then the technology has taken the automotive industry a long way and transformed the bullocks and carts to the high speed cars and automobiles. The use of electronic fuel ignition, the proportionate use of fuel and air so that the efficiency of the smaller engines can be improved, front wheel drive instead of rear wheel drive and many such improvements has just revolutionized the automotive industry.
The use of electronic control in the vehicles was basically introduced to control the emission level. These improved over time and more advanced and sophisticated electronic controls are now used in the cars so as to improve the efficiency of the engines.
The engines today are designed and made of the material that makes them less heavy. This on their part makes the vehicle light and improves its fuel efficiency. A lot of work is been done on the engine of the car so that it consumes lesser amount of diesel, give greater mileage, use fuel efficiently and emit less pollutants.
With the accident on the rise the engineers and designers have worked overnight to come up with the cars that provide a level of safety by the addition of airbags which prevents the driver from the jerk and injury when such incidence happens. There are pre crash systems like forward collusion warning and side alert systems (using infrared sensing system) that are being researched in the labs and when implemented in the future designs will warn the driver of the possible collusion that can occur.
The interiors of the cars are also equipped with all the type of comforts so that the person driving can be at ease and enjoy the drive. The interiors are made more spacious, and cozy with more leg space in the drive seat.

Importance of Technology Financing
It is important for a business to be aware and adopt the latest trends in technology so that it can gain a big share in the market besides developing a competitive edge over its competitors. There are number of software which make the management of the business easier and thus make the business to earn more profits. There are decision support systems, CRM, supply chain management system, ERP, and different information system to support nearly any business activity.
The ERP or enterprise resource planning system uses all the different ERP software to improve the efficiency of business so that the business is conducted in fast and efficient manner. It helps in planning of the resources, controlling different operations and for an overall management control. It is the vital piece of pie which every big organization having its branches in different states and countries should have.
There are different software as well which help in taking decisions. The decision support software helps in the comparison of different factors and the effect of the different factors. Say for example you have to plan a budget for marketing department. Then you have to look into the previous year spending for all those sales activities such as sales promotion, the amount that you can spend on advertising, the target that you have, previous year budget, the market share objective that is to be achieved and so on. This software will give you a comparative trend of all those factors which you consider important for the budget. It will also provide you with trend analysis so that you can analyze the conditions in much better way and plan a budget that is worth.
The technology is thus important for a business to thrive in this highly competitive market. And therefore financing also becomes important.. This is to be done by a team of information technology experts in the company who should analyze every aspect of the business and its requirement of technology. The team should search answer for following questions:
The long term benefits of technology
The ability of the competitors to gain advantage of the technology
The methods by which the technology can be implemented
Sustainability of the technology in future and trend in the technology
The company can be in need of a whole business redesign or a part of a business need to be restructured. A pilot project of technology implementation can also be taken up by the firm which is seriously considering the technological implementation to their business. The redesign of the business is important but it should be implemented carefully. A carefully structured strategy for financing technology can work wonders for a business but on other hand a hasty decision to implement technology without considering the long term outcomes can prove destructive. The decision of technology financing indeed is an important one.

About Different Network Topologies
Network topologies mean the physical layout of the network combined with its logical characteristics. The physical topology or layout refers to the configuration of cables, computers and other peripherals. Topology is the standard term used by the professionals when they refer to the network basic design. While setting up the layout of the network it is necessary to know hat type of equipment the network needs, its capabilities, growth of the network and the way in which network is managed.
There are four basic topologies that are used in the network design. Let us discuss them below.
1. Bus Topology
Bus topology is considered as the “linear bus” because the computers are connected in a straight line. This is the simplest and most common method of network computers. Bus topology has the main run of cable with a terminator at each end and all nodes such as computers are connected to linear cable.
Advantages
Easy to connect and easy to handle and implement.
It is best suited for small networks only.
Disadvantages
The cable length is limited and because of which the stations are limited.
Entire network shuts down if there is a break in the main cable.
It becomes difficult to identify the problem if network shuts down.
Not meant to be used as a stand-alone solution in a large building.
2. Ring Topology
This topology connects the computers on a single circle of cable. The signals travel around the loop in one direction and pass through each computer, which can act as a repeater to boost the signal and send it on to the next computer. It has no terminators at the end and thus is very different from the bus topology.
Advantages
Here a central server is not required for its management.
Easier to manage as compared to the bus.
Provides good communication over long distances.
It handles very high volume of traffic.
It is very reliable.
Disadvantages
The failure of a single node of the network can cause the entire network to break down.
The changes made to network nodes affect the performance of the entire network.
3. Mesh Topology
His topology offers best redundancy and reliability. Here each computer is connected to every other computer by separate cabling.
Advantages
The arrangement of the network nodes is such that it is possible to transmit data from one node to many other nodes at the same time.
You get the redundant paths so that if one cable fails another cable will take over the traffic.
Disadvantages
It is very expensive to install as there are lots of wires used in it.
4. Star topology
In this topology the cable segments from each computer are connected to a centralized component called a hub. Here the signals are transmitted from the distributing computer through the hub to all other computers on the network. The hub only manages and controls all the functions of the network.
Advantages
Easy to install and wire.
No disruptions to the network then connecting or removing devices.
Easy to detect faults and to remove parts.
Disadvantages
It requires more cabling than linear bus topology.
If the hub fails, nodes get disabled.
It is more expensive than linear bus topology.
Thus these are the various network topologies used in the organizations depending on the cost, length of the cable required, types of cable and future growth of the network.

The signals travel around the loop in one direction and pass through each computer, which can act as a repeater to boost the signal and send it on to the next computer. It has no terminators at the end and thus is very different from the bus topology.
Advantages
Here a central server is not required for its management.
Easier to manage as compared to the bus.
Provides good communication over long distances.
It handles very high volume of traffic.
It is very reliable.
Disadvantages
The failure of a single node of the network can cause the entire network to break down.
The changes made to network nodes affect the performance of the entire network.
3. Mesh Topology
His topology offers best redundancy and reliability. Here each computer is connected to every other computer by separate cabling.
Advantages
The arrangement of the network nodes is such that it is possible to transmit data from one node to many other nodes at the same time.
You get the redundant paths so that if one cable fails another cable will take over the traffic.
Disadvantages
It is very expensive to install as there are lots of wires used in it.
4. Star topology
In this topology the cable segments from each computer are connected to a centralized component called a hub. Here the signals are transmitted from the distributing computer through the hub to all other computers on the network. The hub only manages and controls all the functions of the network.
Advantages
Easy to install and wire.
No disruptions to the network then connecting or removing devices.
Easy to detect faults and to remove parts.
Disadvantages
It requires more cabling than linear bus topology.
If the hub fails, nodes get disabled.
It is more expensive than linear bus topology.
Thus these are the various network topologies used in the organizations depending on the cost, length of the cable required, types of cable and future growth of the network.

Facts about the Solar System
We all know that our solar system consists of nine planets all of them revolving around the sun. But there are other interesting things which most of us don’t know. I discovered some while browsing through different websites. So, here I will share with you some interesting facts related to the fascinating system.
The gases and dust particles assembled billions of years ago and started the formation of solar system. They all assembled to form the sun and different planets.
The sun is one among the several stars that you see in the night sky. This is the star which lies close to our planet and hence we all feel the heat. There are 70,000, 000, 000, 000, 000, 000, 000 stars in the universe and sun is one of them.
The sun is surrounded by Mercury, Venus, and Earth. Then there is an asteroid belt after which Jupiter, Saturn, Neptune, Uranus and Pluto follow. The first three planets near the sun are the dense rocky planets while the other planets which lie after the asteroid belt are less dense gas planets. There are dwarf planets as well. These are Ceres lying in the asteroid belt, Pluto and finally the Eris located miles beyond Pluto.
Asteroids are the rocky planets that lie between the Jupiter and Mars orbit. These 90,000 asteroids are the remains of the solar system when it was formed.
Sun forms about 99% of the solar system. Besides planets and asteroids there are 172 moons of different planets, comets and dust.
Our earth is hit by about 10,000,000 kg of meteors everyday. So, lots of dust falls on our planet everyday.
The Saturn is one such planet in our solar system which will float on water if it is placed on it. That’s true! The planet is less dense than the water and if any such thing happens then it would be great to see.
Winds on Neptune are moving at the speed of 2000 km.
Mercury might be the nearest to the Sun but Venus is the hottest planet of our solar system.
Jupiter is the largest one. It is so large that it can hold around 1300 earth in itself.
Pluto takes 248 years to complete one orbit around the sun. It was discovered in 1930, so, we will celebrate its first orbit anniversary in 2178.
The red spot on Jupiter is the hurricane storm.
When Pluto is close to the sun its atmosphere is thin but when it is far away then its atmosphere freeze so that the collapse on the planet and Pluto resembles a comet.
The comets are lumps of ice which come from outer space into our solar system. When they come close to sun then the nucleus sublimates forming a cloud of dust and gas.
All these facts which listed here are just the tip of the iceberg. I suggest you to browse the websites and discover your universe yourself.

They are very exciting to have in our hands but the main feature that should be seen in them is how simple they are! The design, appearance and fun factor are the preferred with the simplicity in mind.
Our lives though loaded with high technology that promises power and convenience, it leaves us fuming in frustration over jumbled software and hundred-page user manuals. So first and the foremost option is making the device very simple and user friendly. Technological success demands simplicity and it is the key factor which every brand company takes into consideration before devising any device.
The Beauty of Simplicity
1. Portability
The beauty of simplicity lies in the smaller and compact devices in the field of media and entertainment. As we can see the bulky CRT TV sets are replaced by the LCD or Plasma TVs. The music players in our homes have now become handy. Thus they are sleeker and smoother fulfilling our entertainment and our needs. The main thing we see that they are simple and anyone can handle them easily without the fear of being damage.
2. Size and budget
Other things that make the gadgets simple are compatibility and high storage facility. For example Xbox 360 is a high end specification and massive technical specifications. They are large, loud, and way too powerful for any game. They even require HD televisions, big sound equipment, wireless broadband internet access, and a dozen other things that not everyone can afford. So these things really make us think that are the simplest ones are Nintendo Wii which requires less support, less money, and less tech happy exploitation of finances. So budget is also the main simplicity factor.
3. Storage capacity
The basic reason behind the popularity of Nintendo Wii is 3D gaming and high storage capacity. With all these features the gadgets become simple to buy which are not very heavy on our pockets. Here the compatibility and high storage capacity speaks a lot.
4. Accessibility
The products have a user friendly interface, most attractive design, straightforward and stylish options that anyone can handle them. Thus the accessibility is also the main concern of simplicity in technology.
It is just to simplify the technology without sacrificing comfort and meaning. It is about subtracting the obvious and adding the meaningful. So if you want to add popularity to your product then it is necessary to add simplicity into it.

Automatic Transmission Fluid
This is the red colored highly refined mineral oil that is used in the vehicles with automatic transmission. The use of automatic transmission fluid differs with different systems. It is used as a lubricant and as hydraulic fluid in different vehicles.
There are three types of automatic transmission fluids. These are Dexron, type F and ATF+. The user manual list the type of ATF used in the vehicle. The manufacturers sometime refer different types of ATF products for different types of vehicle usage.
Modern automatic transmission fluids are formed from a combination of different types of chemical compounds so as to develop a particular ATF specification. These compounds can be anti foam additives, detergents, anti wear additive anti oxidation compounds, high temperature thickeners, petroleum dye and cold flow improvers.
To optimize the performance of your vehicle and its components it is important to perform a routine checkup of the fluid in your vehicle. For this park your car on a level surface and start the engine.
Keep the engine running till it warms up.
To check the ATF in your car keep the engine running. But with some cars it is not required to run the engine while you perform the check up. Therefore consult the user manual before you start the process.
Now with the ATF dipstick check the level of the fluid. This dipstick is similar to the engine oil dipstick but somewhat smaller in size. But before you use it wipe it either with a rag or a cloth for the purpose. Push it in the engine and then remove it. Scan it carefully for two different marks.
One mark is for warm and the other is for cold. Note the mark for warm reading. Now if the automatic transmission fluid does not reach up to the full mark it means that you have to add the fluid to your vehicle.
This is the fluid which is not used up when you drive your vehicle. Therefore if there is low level of fluid then this means that there is some kind of leek. Check your vehicle. Don’t ignore the fault as it may lead to some transmission repairs.
Consult the user manual to find out the type of ATF recommended by the manufacturer for your car. Purchase it and add the fluid in the small hole from where you took out the dipstick. Add slowly.
Don’t overfill the fluid. Overfilling leads to automatic transmission failure. The correct way to add the fluid is to pour slowly using the funnel and checking it simultaneously with the dipstick.
Some new vehicles don’t come with the dipstick. If you own such vehicle then don’t experiment. Find an experienced mechanic to add the fluid to your vehicle.

Generic Projection Lamp
Generic lamps are basically the similar in temperament or copy lamps but not manufactured by the OEM lamp manufacturing company. These lamps are made by the brands like Osram, DNGO and Arclite. A generis lamp costs less as compared to the OEM made lamps because of various reasons.
The very reason is that it involves inferior workmanship quality.
It includes lower manufacturing costs.
The lifespan of the product is poor and inconsistent.
It offers poor luminosity and premature inner failure.
There is lot of difference between OEM lamps and other generic lamps. The OEM manufactured lamps last 3 times even if you need to pay bit extra.
There are lots of risks associated with generic or ordinary lamps such as premature explosion and loss of lumens.
They are not as bright as the original manufacturer.
These generic lamps last only for about 6 months and 1 year. Thus for the cost-benefit options you should consider buying the OEM lamps.
An original lamp is made to work more efficiently and last longer. The lighting element inside a UHP lamp is built to resist consistent use ignition from the weight at 20,000 volts at a time. But the generic lamps are just made to work with original lamp drivers, not taking into consideration the life span or the weight of heavy volts.
In the OEM lamps the arc gap is typically 1 mm and the electrical arc must be aligned accordingly. But the generic lamps have a shorter life span and lose luminosity over time by imploding faster.
If you have the Philips VHS lamps then you do not have to worry about the defects and they are usually used in home theater lighting, digital projection lighting thus useful in saving power.
Most of the DLP and LCD projections systems use Philips as their OEM but here the generic projection lamps are not preferred.
Philips has worked in tandem with multiple television manufacturers to develop the best lamp drivers with the best lamps. Lamps must not only be compatible with the lamp driver, but work as one unit, something you won’t get with off-brands, or third-party manufacturers.
An OEM lamp will never fail prematurely, and will always be the best choice because it’s designed to be 100% compatible with your lamp driver, or ballast. But the same problems will appear in generic lamps.
Thus these generic projection lamps are not at all the preferred lamps because of their low quality and low luminosity, poor lifespan and premature implosions. These generic lamps though are inexpensive on your pocket but lack in quality. So it is always preferred to use the original, high quality made lamps from OEM or Philips brands.

Cellular technology
We are aware of the different types of mobile handsets used that are coming with completely different features and high-end specifications and is very helpful in every field for getting the productive and excellent results. Mobile handsets have brought a revolution in the telecommunication industry.
It is with the help of this drastic change in the telecommunication, everybody is getting the perfect benefits in terms of communication and computation. By deploying cellular technology in an organization, it will help the employees to access databases, order products and retrieving technical specifications or off site sales staff responding to customer inquiries.
There are six basic components found in most of the cellular systems which tells us the inside features of the cellular system design. Let us have an understanding of the cellular system.
1. Mobile station
A mobile station is basically a mobile or wireless device that contains a control unit, a transceiver and an antenna for data and voice transmission. The very example is in GSM networks where mobile stations have mobile equipment (ME) and the SIM card.
2. Air Interface Standard
There are three main air interface standards such as time division multiple access (TDMA), code division multiple access (CDMA) and frequency division multiple access (FDMA). These air interface standards allow many mobile users to share simultaneously the fixed amount of radio channels. These standards are basically the medium access control (MAC) protocols that define the rules for units to access the communication medium.
3. Base Station
It is the fixed station in the mobile cellular systems used for radio communications with mobile units. Base station consists of radio channels and transmitter and receiver antenna mounted on a tower.
4. Gateway
This gateway is the communication link between two wireless systems or one wireless and other wired system. The logical components in gateway are Mobile Switching Center (MSC) and interworking function (IWF).
MSC helps in connecting the cellular base stations and the mobile stations to the public switched telephone network (PSTN) or other MSC.
IWF helps in connecting the cellular base stations and the mobile stations to Internet and perform protocol translation if needed.
5. Databases
They are also the most important feature of cellular technology. Home Location Register (HLR) and Visitor Location Register (VLR) are the two main databases used.
HLR is the database that contains the data of those subscribers that reside in the same city as MSC. The VLR provisionally stores the information for each visiting subscriber in the coverage area of a MSC.
The VLR is actually the database that supports roaming capability.
6. Security mechanism
This mechanism helps the subscriber to access the particular network and also to validate the billing for him.
The databases used for security mechanism are the Equipment Identify Register (EIR) and Authentication Center (AuC).
The EIR is the register that identifies stolen or fraudulently altered phones that convey identity data that does not match with information contained in either the HLR or VLR.
The AuC administers the actual encryption and confirmation of each subscriber.
Thus we learn about the major components and help us in knowing the cellular architecture.

Mobile handsets have brought a revolution in the telecommunication industry.
It is with the help of this drastic change in the telecommunication, everybody is getting the perfect benefits in terms of communication and computation. By deploying cellular technology in an organization, it will help the employees to access databases, order products and retrieving technical specifications or off site sales staff responding to customer inquiries.
There are six basic components found in most of the cellular systems which tells us the inside features of the cellular system design. Let us have an understanding of the cellular system.
1. Mobile station
A mobile station is basically a mobile or wireless device that contains a control unit, a transceiver and an antenna for data and voice transmission. The very example is in GSM networks where mobile stations have mobile equipment (ME) and the SIM card.
2. Air Interface Standard
There are three main air interface standards such as time division multiple access (TDMA), code division multiple access (CDMA) and frequency division multiple access (FDMA). These air interface standards allow many mobile users to share simultaneously the fixed amount of radio channels. These standards are basically the medium access control (MAC) protocols that define the rules for units to access the communication medium.
3. Base Station
It is the fixed station in the mobile cellular systems used for radio communications with mobile units. Base station consists of radio channels and transmitter and receiver antenna mounted on a tower.
4. Gateway
This gateway is the communication link between two wireless systems or one wireless and other wired system. The logical components in gateway are Mobile Switching Center (MSC) and interworking function (IWF).
MSC helps in connecting the cellular base stations and the mobile stations to the public switched telephone network (PSTN) or other MSC.
IWF helps in connecting the cellular base stations and the mobile stations to Internet and perform protocol translation if needed.
5. Databases
They are also the most important feature of cellular technology. Home Location Register (HLR) and Visitor Location Register (VLR) are the two main databases used.
HLR is the database that contains the data of those subscribers that reside in the same city as MSC. The VLR provisionally stores the information for each visiting subscriber in the coverage area of a MSC.
The VLR is actually the database that supports roaming capability.
6. Security mechanism
This mechanism helps the subscriber to access the particular network and also to validate the billing for him.
The databases used for security mechanism are the Equipment Identify Register (EIR) and Authentication Center (AuC).
The EIR is the register that identifies stolen or fraudulently altered phones that convey identity data that does not match with information contained in either the HLR or VLR.
The AuC administers the actual encryption and confirmation of each subscriber.
Thus we learn about the major components and help us in knowing the cellular architecture.

How to Build an Electric Car
Rising fuel prices and increasing level of pollution is forcing individuals worldwide to search for alternatives technologies. Solar water heaters, solar heating system, use of geothermal energy, vehicles with improved fuel efficiency, battery driven vehicles, hydrogen cars and hybrid cars are some on the alternative technologies which are commonly used by the individuals so as to bring down their monthly electricity and fuel bills and make their planet a better place to live in. Electric cars are also a step in this direction.
Electric cars are the cars which run on batteries. You don’t have to fill fuel to run it. For them you just require a pair of batteries and a charger to charge it. The engine of the electric cars has a series of batteries which is attached to a switch and this switch is in turn attached to the electric motor. The power is supplied by the battery which runs the motor and this motor in turn drives the wheels.
How to build your own electric car?
Although the electric car appears simple in construction but if you aim to convert your gasoline vehicle into an electric car then indeed you have taken up a daunting task. Electric vehicle kits are available in the market which helps you to convert your gasoline car to an electric car.
An electric car simply has a series of batteries and an electric motor. To convert your gasoline car you have to remove most of the components that make up your car. The task thus needs some conceptual clarity with the cars. Therefore if you want to convert your fuel car to one which runs purely on batteries then first step should be to educate yourself well about the gasoline cars and the electric cars. Understand the car mechanics before you shed the parts of your car.
The job is half done once you are clear with the basics. You now just need to remove the parts, make your vehicle light in weight, place the electric motor and the batteries and interconnect them to run your own electric car. The conversion kits along with the conversion manual are available in the market. These manuals have step by step instructions which guide you to construct your own electric car.
But not all cars can be converted to electric cars. Chevy Geo especially a model of 1989 to 1999 times can be converted to an electric car very easily. Besides these, Chevy Sprint and Suzuki Swift also readily take up the conversion.
What is the cost of conversion?
The conversion is a one time cost. The kits can cost you around $8000 to $10,000. But this is a one time investment. You recover the amount from the amount that you save on fuel.
