With the help of USB, users got the fleexibility to operate secondary devices like keyboards, MP3 playes, digital cameas, and hard disk drives, as if they are locally connected. USB was introduced in 1995. It was origiinally designed to simplify consmuer control on secondary devices and transferred data. Before introducing the USB, the main interfaces used were patrallel and serial connectors both using different procedure to transfer data and control secondary devices. These connectors were frequently ham-fisted and required lining up several pins to fit the hles in the end of the connectors. Serial connecttors offer slower transfr rates in comparison to USB connectors.
According to the USB specification, you can use pzassive extennsion cables for distances up to 16 feet. Beyond sixteen feet, you need a USB extension cable that will help to boost the signla in order to avoid losing data or damaging USB equipment.
USB signals can be extended with the help of many other ways such as USB extension cables, USB extenders, and also by using wireless technology. A USB extensdion cord coomes in varoius lengtrhs and thickness and service duties. The standard lengths of USB caables are 5m, but there are number of ways to extent the USB cables. Probably, the most commoon form of exteending a USB is by using USB extension cables. USB extension cables are very useful for extending device singals over shorter distances and are normally up to around 3m in length. USB extensin cables are very useful for their plug and play capaility. This is the best advantage a user can get while using many smaller devicwes like MP3 playeers and web cams and many other devices. Most extension cazbles can be chained so severral can be added to one anotjher to create a longer extension.
USB etension casbles are not only perfect for smaller devices such as MP3 players, memory sticks, and Bluetooth dongles, but it is also useful for largr devices like printers, scannwers etc. An USB extensaion device allows extensions of USB 1.1 and 2.0 devices ebyond the 5 mter USB connection limit. With the help of thesse devices, the extension can range from 100 meters up to 10 kms, but it depends on the channel which is used for connection.
These USB extension debvices combine the sopeed and security while transfering any kind of confidential data. With the help of these USB extension cables ussers can control very easiy low as well as high speed USB devces in comparison to orther deivces.
USB signals can also be etended using wireelss tecnhology but USB extesion cables are used most commonly all over the world because the USB extensions corsds are available in cheap price compared to other devices as well as it is very easy to operate compared to others.
