<p>Attached Resource Computer NETwork (ARCNET or ARCnet) is a <a href="/facts/Communications_protocol/5uady7cB">communications protocol</a> for <a href="/facts/Local_area_network/edUDxJ6J">local area networks</a>. ARCNET was the first widely available <a href="/facts/Computer_network/3w5RM99p">networking</a> system for <a href="/facts/Microcomputer/ETW22UTv">microcomputers</a> and it became popular in the 1980s for office automation tasks. It was later applied to <a href="/facts/Embedded_system/a4muX1wU">embedded systems</a> where certain features of the protocol are especially useful. </p>
