data communication and computer networks pdf in hindi

Now we need such a design for Ethernet in which we have a minimum number of collisions.

Another computer may attempt to transmit at the same time, which causes a collision.Ī collision domain is a physical network segment where data packets can 'collide' with one another for being sent on a shared medium, in particular in the Ethernet networking protocol. When the cable is not busy, a computer attempts to transmit. com/univ/free-asgn/mcs42/Image57.gifĬoncept of collisionsThe basic strategy goes like this: A computer listens on the cable to see if another computer is transmitting, which is indicated by a voltage change on the cable.

These transfer data to and from systems across the network Hardware cables, connectors, and circuitry. This method controls packet transmission and information flow across the Ethernet hardware. These are units of data sent across the network. Ethernet in fact is the standard today Reasons: Simple Cheap ManufacturersĮthernet architecture is based on the concept of connecting multiple computers to a long cable sometimes called the ether, using transceivers.Ībout EthernetThe three major elements of Ethernet networks are: Ethernet packets are called frames. The original Ethernet enabled computers located within a few hundred yards of one another to exchange messages.
