In circuit switching, a connection is established between two network nodes before they begin transmitting data. Bandwidth is dedicated to this connection and remains available until the users terminate communication between the two nodes. While the nodes remain connected, all data follows the same path initially selected by the switch. This works much like a Read More …

Bus Topology – This topology consists of a Backbone cable connecting all nodes on a network without intervening connectivity devices. The single cable is called Bus and can support only one channel for communication; as a result, every node shares the bus’s total capacity. On a Bus Topology network, devices share the responsibility for getting Read More …

Carrier Sense Multiple Access/Collision Detect (CSMA/CD) is a scheme where the hosts try to detect collisions, and if they occur, stop transmitting, and then try to re-transmit at a later time. Any host on the network segment that wants to send data must check the segment to see if another host is already sending data. Read More …
