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.
