Random Access Carrier Sense Protocol

Communication is a process of transforming interpreting and processing information among persons or machines. This process involves a sender receiver and transmission medium over which the information flows. Traditionally when a small group of computing devices are interconnected together for data communications services it is referred to as a local area network (LAN). LANs provide connectivity and services for data flow and sharing in an organization. The medium of choice for physical level interconnectivity in a LAN has been copper wire. Copper wire is inexpensive readily available and easy to install. As the need for more bandwidth has become more apparent fiber optic cabling has begun to play an important role in LAN connectivity.
