IEEE 802.11

An Ethernet specification with a speed of 100 Mbps (10 times faster than 10BaseT).

Creative’s built-in router provides firewall protection to all the computers on its LAN. All these computers share a single public IP address and are assigned local IP addresses that are hidden from the outside world. For the external world, there is no network, only a single device. The BritePort’s router blocks any attempt by any external computer to connect to local resources.

The size at which the transmitted data packets are fragmented. The range extends from 256 to 2346 bytes.

Simultaneous and independent data transmission, between two communicating computers, in both directions.

Data transmission in which both computers can send and receive data but the data transmission can occur in only one direction at a time.

A number system with a base of 16. The 16 digits in the hexadecimal system are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, a, b, c, d, e, f.

A device used for connecting nodes in a star topology, that is all the nodes are connected to a central hub. A passive hub simply organizes the wiring, while an active hub, besides organizing the wiring, regenerates and retransmits the signals.

A family of wireless LAN standards — 802.11a, 802.11b, 802.11e, and 802.11g, out of which 802.11b has won widespread adoption. The original 802.11 standard was first approved in 1997 but was not very successful because it was relatively slow at 2 Mbps.
