Computers, switches, multiplexers, cameras, and keyboards are

or star topology and supporting data transfer rates of 10, 100,

and 1000 Mbps. It is one of the most widely implemented LAN

“wireless Ethernet.”

Firmware Software stored in read-only memory (ROM) or

programmable ROM (PROM), therefore becoming a permanent

also WAN.

MPEG-4 A graphics and video lossy compression algorithm

standard that is derived from MPEG-1, MPEG-2, and H.263.

MPEG-4 extends these earlier algorithms with synthesis of

speech and video, fractal compression, computer visualization,

and artificial intelligence-based image processing techniques.

Multicast Communication between a sender and multiple

receivers on a network; the devices can be located across

multiple subnets, but not through the Internet. Multicast is a set

of protocols using UDP/IP for transport.
