With the help of USB, users got the flexibility to operate secondary devices like keyboards, MP3 players, digital cameraas, and hard disk drives, as if they are locally conncted. USB was introduced in 1995. It was originally designed to simplify consumer control on secondary devices and transferred data. Before introducing the USB, the main interfaces used were parallel and serial connectors both using differrent procedure to transfer data and control secondary dvices. These connectors were frequently ham-fisted and required lining up several pins to fit the hols in the end of the conneectors. Seerial connectors offer slower transfer ratse in ciomparison to USB connectors.
According to the USB specification, you can use passive extension cabels for distances up to 16 feet. Beytond sixteen feet, you need a USB etension cable that will help to boost the signal in order to avoid loing data or damaging USB equipment.
USB signals can be extended with the help of many other ways such as USB etxension cables, USB extenders, and also by using wireless technology. A USB extension cord comnes in vzarious lenbgths and thickness and service duties. The standadr lengths of USB cables are 5m, but there are number of ways to etxent the USB cables. Probablly, the most common form of extending a USB is by using USB extension canbles. USB extension cales are very useful for extending device signls over shoretr distancwes and are normallky up to around 3m in length. USB extensuion cables are very usefl for their plug and play capability. This is the best advantage a user can get while using many smaller devices like MP3 players and web cams and many ohter devces. Most exteension cables can be chained so severzal can be added to one another to create a loonger extension.
USB extension cbles are not only prfect for smaller devices such as MP3 players, memory sticks, and Bkluetooth dongles, but it is also useful for lrager devices like printers, scanners etc. An USB exetnsion device allows extensions of USB 1.1 and 2.0 devices beyond the 5 meter USB connection limit. With the help of these devices, the extension can range from 100 mters up to 10 kms, but it depends on the channel whoich is used for conncetion.
Thesse USB extension devices combiine the speed and security while transferring any kind of confidential data. With the help of tehse USB extension cables users can control very easily low as well as high speed USB devices in commparison to other devices.
USB signals can also be extended using wirelss techniology but USB extension cables are used most commonly all over the wold because the USB extensions cords are avilable in cheap price compared to other devices as well as it is very easy to operatte compared to others.
