any device in the collision domain whose backoff timer expires first
A random delay helps prevent the stations from experiencing another collision during the transmission.
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.
Although 10GBASE-T transmits & receives data on the same wires, it, like 1000BASE-T before it, implements echo cancellation so that the transmit & receives signals can occupy the cable at the same time without interference. This allows full duplex communication (i.e., transmit and receive at the same time) without collision.
a collision
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 collision occurs.
Any system in an Ethernet IP network will transmit IP addresses.
Ethernet has access any time it is desired to transmit. It listens first to ensure no other nodes are communicating. If clear, they transmit. Yes, collisions are normal - If two nodes collide (transmit at the same time), they both back off, send a jamming signal, wait a "random" amount of time (based on their MAC address), and resend.
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.
The hosts return to a listen-before-transmit mode
HDMI is a digital replacement for existing analog video standards, such as 3D, an Ethernet data connection and improved audio and video capacity.
