GROWTH OF LAN TECHNOLOGY
The production of shared communication channels (LANs) started in 1960s and early 1970.
The basic idea behind was to reduce the number of connections by sharing connection among several computers. Every LAN consists of a single shared phase. The computers give turns using the phase. First one computer needs the medium to send its data over the communication channel then second and son on. But sharing a single medium over big distances is not efficient, due to the long time taken.
LAN technologies reduce expenses by reducing no. of connections. But attached computers compete for need of shared connections. The local interaction consists of LAN exclusively. But the long distance interaction is point-to-point exclusively.
