In this article we will discuss ARCNET, will make brief discussion on ARCNET, last article we discuss about Ethernet.
Attached Resource Computer NETwork (ARCNET orARCnet) is a communications protocol for local area networks. ARCNET was the first widely available networking system for microcomputers; it became popular in the 1980s for office automation tasks.
ARCNET is a widely-installed local area network (LAN) technology that uses a token-bus scheme for managing line sharing among the workstations and other devices connected on the LAN.
ARCNet uses the token-passing protocol over a star and bus topology. The star and bus topology combines the flexibility of a star with the simplicity and throughput of a bus. Thus, ARCNet standard has a unique protocol/topology combination: token-passing protocol and Distributed star/bus topology.
Like Ethernet and Controller Area Network (CAN), ARCNET is a data-link layer technology with no defined application layer. ARCnet is an extremely easy-to-install LAN since it offers a flexible topology with few limitations. It can be configured as a simple Star or Bus topology network, or a Combined Star and Bus topology network. The ARCnet card is equipped with a standard BNC female connector for connection to RG-62 A/U coaxial cable.
ARCnet can be configured in a simple star or bus topology, or in a combined star and bus topology. ARCnet can use unshielded twisted pair (UTP) wiring, coaxial cable, or optical fiber. The primary characteristics of ARCnet include:
■ 2.5 Mbps transmission
■ Support for up to 255 nodes
■ Coax cable lengths up to 2000 feet (600 m)
■ Twisted pair cable lengths up to 400 feet (120 m)
I am Hamza arif, and i am excited to learn new things, i am well focused for my work and always try to explore new things. My graduate is in BS (Telecom) and i am expert in Networks and working on new technology is my passion i work a lot on AI (Artificial Intelligence) Augmented Reality and many other projects.
