through which public and private organizations develop
telecommunications. The ITU was founded in 1865 and
became a United Nations agency in 1947. It is responsible for

geographical area, such as a single building. The network
typically links PCs as well as shared resources such as
printers.
MAC Media Access Control. The lower of the two sub-layers of the
data link layer defined by the IEEE. The MAC sub-layer
handles access to shared media, such as whether token
passing or contention will be used.
MAC Address Standardized data link layer address that is required for every
port or device that connects to a LAN. Other devices in the
network use these addresses to locate specific ports in the
network and to create and update routing tables and data
structures. MAC addresses are 6bytes long and are controlled
by the IEEE.
