ARCNET

• ARCNET (Attached Resource Computer Network) is a system for data transmission in local networks.
• The ARCNET protocol is based on the Token Passing principle.
• By passing an identifier (token) from station to station it is guaranteed, that only one station can start a data transmission (transmission without collision).
• The order of sequence, in which the stations are accessed, is automatically adapted by the existing conditions in the network, i.e. that the network is reconfigured automatically each time a station is added to the network or switched off.
