How ARCNET works?

ARCNET (Attached Resource Computer Network) is a local area network (LAN) technology that utilizes a token-passing protocol for data transmission. It operates over twisted-pair or coaxial cables and supports a star or bus topology. In ARCNET, a token circulates through the network, granting permission to devices to send data, thus ensuring orderly communication and preventing collisions. Originally developed for industrial applications, it allows for reliable data transfer at speeds typically ranging from 2.5 Mbps to 10 Mbps.
