ProNET Token Ring Technology

ProNET Token ring technology is an alternative to ethernet technology and it also works fairly good speeds. It uses token ring technology- Token ring network as shown above consists of hosts connected as a ring via wires that comes out of each host and connected to the other host. Each host in the network engage…

Ethernet Variations

Ethernet technology started with using the costly coaxial cables. Now it is possible to carry ethernet frames over cost-effective and cheaper twisted pair cables supporting greater speeds. Another variation of ethernet is to use cable like that of cable TV. This variation of Ethernet is called thin wire ethernet which is expensive but cover only…

Ethernet Bridges

Ethernet bridge is a fast computer with two Ethernet interfaces and a fixed program that improve upon the functions of repeaters by replicating the packets, instead of amplifying them. Bridges, thus do not amplify the noise, errors or malformed frames like the repeaters, but only reproduces a completely valid frame. Ethernet bridges supports CSMA/CD mode…

Ethernet addressing and frame format

Ethernet Addresses refers to the unique physical/hardware address assigned or hardcoded on to the Ethernet interface card in 48 bits machine readable form. Physical ethernet addresses are meant to be different for each interface card and moving the hardware to a new machine or replacing the existing card with a new one will change the…

Collission detection and Recovery in Ethernet

Ethernet data transmission enabled by TCP/IP is a best-effort delivery method. i.e the sender is given no information about whether the data packets were received by the receiver or not. The hosts in the Ethernet participate in data communication over the common Ethernet bus by a process of carrier sense multiple access with collision detection…
