To indicate to the network that a particular node is about to transmit data
it prevents the collision between the data that is sended by the network cards over ethernet networks
Ethernet over E1 converter (also called E1 network bridge) is to transmit Ethernet data over E1 network (PDH,SDH network etc). The Ethernet port connect to terminal device,computer,Ethernet switch,Ethernet router etc. The device's E1 port connect to mail network(PDH SDH etc).E1 over IP (TDMOIP) is to transmit the E1 data over ethernet IPnetwork. It transports the legacy E1 data through the existing Ethernet or IP network. The typical application is transmit voice and data over wireless radio network.
A MAC address is used as a unique identifier that is assigned to network interfaces. Two networking devices that transmit packets based on MAC addresses are switches and bridges.
A collision domain is an area on the network where two devices may attempt to transmit at the same time. A hub has 1 collision domain overall. A switch has 1 collision domain per interface. The fewer devices in 1 collision domain, the better. ----
Collision domains are really bad. Not only does each computer get everyone's frames, but only one PC can transmit at a time! Your total bandwidth is reduced every time you add a PC to the network. Your network will come to a screeching halt!
A jam signal indicates that the collision has cleared and the media is not busy.X A device listens and waits until the media is not busy before transmitting.The device with the electronic token is the only one that can transmit after a collision.X All of the devices on a segment see data that passes on the network medium.X After detecting a collision, hosts can attempt to resume transmission after a random time delay has expired.
Full Duplex Ethernet uses no network control protocal to prevent collisions. This is because full duplex has a deicated channell for transmit and receive. When communicating in full duplex mode, there is no area to have a collision.
My answer is not wrong
A collision domain is a physical network segment where data packets can collide with one another when being sent on a shared medium.A group of Ethernet or Fast Ethernet devices in a CSMA/CD LAN that are connected by repeaters and compete for access on the network. Only one device in the collision domain may transmit at any one time, and the other devices in the domain listen to the network in order to avoid data collisions.A collision domain is sometimes referred to as an Ethernet segment.
Zero. No collisions can occur within a full-duplex environment, as transmit and receive operations are performed on another set of wires. Thus, no collision domains would exist. Carrier Sense Multiple Access with Collision Detection (CSMA/DC) is not part of a full-duplex network for this reason.
In most modern-day network switches, collision is no longer a problem. Network switches are good at handling these situations to avoid collision problems.
