It has more than 300,000 members and is involved with setting standards for computers and communications. WECA s focus is on 802.11b, an 11 Mbps high rate DSSS standard for wireless networks. The AP not only mediates wireless network traffic in the immediate neighborhood, but also provides communication with the wired network. Each computer on the Internet has at least one address that uniquely identifies it from all other computers on the Internet. Each of these packets contains both the sender's Internet address and the receiver's address.
Any packet is sent first to a gateway computer that understands a small part of the Internet.
The gateway computer reads the destination address and forwards the packet to an adjacent gateway that in turn reads the destination address and so forth across the Internet until one gateway recognizes the packet as belonging to a computer within its immediate neighborhood or domain. That gateway then forwards the packet directly to the computer whose address is specified. Because the data is divided into a number of packets, each packet can, if necessary, be sent by a different route across the Internet. A packet is treated as an independent unit of data so packets can arrive at their destination in a different order than they were sent in. An IP address is a 32-bit number that identifies each sender or receiver of information that is sent across the Internet.
