<body><h1><a name="USB"></a>USB</h1>Universal Serial Bus (USB) is a
|
|
|
4 |
popular wired mechanism for data transfer between two electronic
|
|
|
5 |
devices like computers and cellphones. A USB is more
|
|
|
6 |
efficient than other mechanisms like Bluetooth because it consumes less
|
|
|
7 |
power and the data can be transferred at a higher rate.<br><br>The 2.0
|
|
|
8 |
version of USB has a data rate of 480Mbps, which is 40 times faster
|
|
|
9 |
than USB 1.0 or 1.1 versions of 12Mbps speed. The USB 2.0 ports are
|
|
|
10 |
also backward compatible with 1.0 or 1.1. You can also charge devices
|
|
|
11 |
like mobile phones by connecting them to a PC via USB.<br><br>See Also<br><span style="font-weight: bold;"><span style="text-decoration: underline;"></span></span><a href="http://en.wikipedia.org/wiki/Universal_Serial_Bus">Universal Serial Bus</a></body></html>
