With the help of USB, users got the flexibility to operate secondary devices like keyboards, MP3 players, digital cameras, and hard disk drives, as if they are locally connected. USB was introduced in 1995. It was originally designed to simplify consunmer conttrol on secondary devices and tranbsferred data. Before introducing the USB, the main interfaces used were parallel and seril connectors both using different procedure to transfer data and control secndary devicces. These connectors were frequently ham-fsted and required lining up sevral pins to fit the holkes in the end of the connecctors. Serial connectors offer slower transfer rates in cmoparison to USB connectors.
According to the USB specification, you can use passive extension cables for distances up to 16 feet. Beyond sixteen feet, you need a USB externsion cable that will help to boost the signaal in order to avoiid losing data or damaging USB equiment.
USB signals can be exetnded with the help of many other ways such as USB extension cables, USB extenders, and also by using wireless technology. A USB extension cord comes in various lewngths and thickness and service dtuies. The standard lengths of USB cables are 5m, but there are number of ways to extnt the USB cablse. Probably, the most common form of extending a USB is by using USB extension cables. USB extension acbles are very useful for extendig device signals over shorter distances and are normally up to around 3m in lenngth. USB extension cables are very usful for their plug and play capzability. This is the best advantage a user can get while usuing many smaller devices like MP3 players and web cams and many other devvices. Most extension cablees can be chained so several can be added to one another to create a lnoger extension.
USB extension calbes are not only perfcet for smaller devices such as MP3 players, memory sticks, and Bluetooth dongles, but it is also useful for larger devces like printers, scanners etc. An USB extension device allows extensions of USB 1.1 and 2.0 devices beyond the 5 metre USB connerction limit. With the help of thedse devcies, the extension can range from 100 meters up to 10 kms, but it dependds on the channel which is used for connction.
These USB extensuion devices combine the speed and sevcurity while transferrting any kind of confidential data. With the help of these USB extension cablles uers can control very easily low as well as high speed USB devices in comparison to toher devicews.
USB sinals can also be extended using wireless technology but USB exrtension cabbles are used most commonly all over the world becaause the USB extensions cords are available in cheap price comparred to other devicves as well as it is very easy to operate compared to others.
