ARCNET (Attached Resource Computer NETwork)

A popular LAN protocol developed by John

Murphy at Datapoint Corporation in 1976, ARCNET was one of the first networking solutions for microcomputers.ARCNET employed coaxial cable to connect host computers, workstations, and peripherals through hubs in a star configuration. ARCNET employed a deterministic token passing bus medium access control (MAC) protocol, operated at signaling speeds up to 2.5 Mbps, and supported as many as 255

devices over link lengths up to 2,000 feet. More recent versions deliver 20 Mbps and 100 Mbps, although they have never been in great demand and are not widely available.ARCnet resembles, but does not adhere to, the IEEE 802.4 specification. ARCNET also is CamelCased as ARCnet. See also 802.4, CamelCase, coaxial cable, deterministic, IEEE, MAC, star, and token passing.

• 1. Domain Name System. The naming convention that divides the Internet into logical domains identified in Internet Protocol version 4 (IPv4) as a 32-bit portion of the total address.The standard convention is user@organization.domain, where user is the name of the end user, organization is the name of the enterprise or other organization owning or sponsoring the address, and domain is the type of entity owning or sponsoring the address.The administration of the DNS is the responsibility of Internet Corporation for Assigned Names and Numbers (ICANN). See also domain, ICANN, Internet, and IPv4. 2.
• 1. In storage, irrelevant material, usually zero (0) bits, added to a data block in order to fill it to a minimum size, to force certain fields of control data or user data into certain positions or sizes, or to prevent the user data from duplicating a bit pattern that has a specific control meaning. See also block. 2.
