VGA Extender: Helps Place Computers in a Secure Location and Relay Information to Public Places

VGA Extender allows long distance transmission of video signals using category cables. Since cat5/6/5e cables are used, a distance of up to 950 feet can be achieved and use of bulky VGA cables is also eliminated thereby saving space and reducing clutter. For even greater distances, one can use the high end version which relays signals over fiber optic cables. This model operates on single and dual link fiber optic technology. Comprised of two units, a transmitter and a receiver, the former is connected with the source unit and the latter to the display. Once the connections are secured and the unit powered on, the device is ready to be used.  Alternatively known as the vga to cat5 extension device, it works on simple plug and play functionality, is easy to install and does not require any additional software or device drivers for operation.

While maintaining signal strength, the extenders transmit crisp and clear images at a resolution of 1900 x 1200. Sizes range from 2 port to 4 and 8 port devices and some models are also available with optional audio, RS232 and infra red remote control. Offering multi platform support, they are compatible with almost all operating systems and are powered using 12V power supplies. They also have the ability to provide secure access and control of the infrastructure as PCs can be placed in a safe secure environment.

While the VGA extender over CAT5 is the basic model, more advanced models of video extenders are also available. These models are categorized on the basis of signals they support such as the DVI, HDMI, Composite and Component Extender. Wireless extenders are also available which were introduced to eliminate the wired clutter from the tech environments. They are equipped with session security log-in and Wi-Fi WEP protection and allow any desktop or notebook computers with Wi-Fi to access the VGA monitor or projector.

The VGA extension units can work with many video sources with a VGA connection, including PCs, DVD players, VHS, DVRs and so on. Since it can be used in environments where the video inputs need to be sent to multiple remote output devices, the VGA extender finds its use in digital signage applications, educational and commercial establishments, financial institutions etc.

How Computer Technology Helps In Education?

Computer has become the prime thing now a day. Everything is done with the help of computer be it booking tickets for films or ordering pizzas for home. In offices where previously files used to be maintained in papers, now everything has been converted into digital form. All the files are saved in the computer memory. The new generation does not understand anything beyond computers. They have almost forgotten how to socialize with others because when they come back at home, the only thing they do is sit in front of the computer.

Even in the schools, computer plays a vital role. One has to be a computer literate even to get a job. Employers do not recruit employees who do not have any knowledge about computers. Education with computer knowledge can be made a precious resource not only for students but also for teachers, educators and even parents.

Before educating the students with knowledge of computer, teachers should get the knowledge properly. The more teachers will know about computers, the more they can teach the students in a proper way. The knowledge of both teachers and students should not be stuck in computers only, there is a much worthy and interesting thing beyond that and that is Internet.

Schools should provide the students with the opportunity to access the Internet and the World Wide Web to develop knowledge of high quality to use the current technology. Earlier, computer technology in schools used to be considered as luxury but now it has become more of a requirement than luxury for students. Every student or even those who are no more a student now have a personal computer at their homes be it a desktop or a laptop. The use of computers application is quite a necessary thing because it helps a person to maintain relation with the real world applications.

Many people say computer technology distracts students from studies and destroys their creativity skill. But it completely depends upon the individual how the person is taking the education through computers. Using anything with a bad or useless intention will result negative. If it is used with an intention to gather knowledge then it will definitely result in a positive way. Children should be guided by the teachers or educators as well as by the parents about the right use of computers.

Apart from studies, computers are also used for other works. After the advent of computers and internet people have stopped sending letters to each other. Instead of sending letters they send e-mails now. In fact, people do not go to different organizations or offices to submit their resumes; they simplify the work by submitting it online. Now the world is not like earlier. Since, every country has its access to Internet; it has become easier to make deals with various countries at a time.In education, subjects like math have become easier for students as it takes a few seconds to solve the equations. Computers are also used vastly by students for their projects and assignments. A single box can solve so many problems. Isn’t it great?
