as the 48-bit MAC address and Ethernet frame format have influenced other networking protocols. Ethernet is a family of computer networking technologies for local area networks‚ known as LANs. Ethernet was commercially introduced in 1980 and standardized in 1985. Ethernet has largely replaced competing wired LAN technologies such as a token. The Ethernet standards comprise several wiring and signalling variants of the OSI physical layer in use with Ethernet. The original Ethernet used coaxial cable as

access to the shared ring media. Stations that have data frames to transmit must first acquire the token before they can transmit them. Token ring LANs normally use differential Manchester encoding of bits on the LAN media. Token ring was invented by Olof Söderblom in the late 1960s. It was later licensed to IBM‚ who popularized the use of token ring LANs in the mid 1980s when it released its IBM token ring architecture based on active multi-station access units (MSAUs or MAUs) and the IBM Structured

A fax machine is a device that can send a copy of a paper document over the telephone network. The sending fax converts the light/dark areas of the printed document into noises. These noises travel through the phone system and are received by another fax machine. The receiving fax machine converts the noises into printed

A motherboard‚ a CPU‚ a keyboard and a monitor are all items of hardware What is Software? Software is a collection of instructions that can be ‘run’ on a computer. These instructions tell the computer what to do. Software is not a physical thing (but it can of course be stored on a physical medium such as a CD-ROM)‚ it is just a bunch of codes. An operating
