802.11b and 802.11g

802.11 is a wireless specification that is specified by IEEE - the institute of Electrical and Electronic Engineers.  However, most of us just think of it as the most common wireless computer connection that is currently in usage. It allows the transmission of data mostly to laptop and other computers.  If you have a wireless internet and networking connection at home or at work, the chances are good that it is an 802.11 network.

802.11b was the original specification.  It operates at the 2.4 Ghz frequency band and up to 11 Mbps (million bits of data per second). 802.11g operates also at 2.4 Ghz, but offers even higher data speeds, up to 54 MBps.
