Collision is the effect of two devices sending transmissions simultaneously in Ethernet. When they meet on the physical media, the signals from each device collide and damaged. Collision domain Collision domain is the group of devices that share same collision effects over the Ethernet network. CSMA/CD It is a mechanism of removing collision from network. When two or more nodes simultaneously sense the wire and found no signals, and each device places it’s signal on the wire. These signals would be collide in wire and a collision will occur. Before placing any signal in wire, NIC (Network Interface Card) examines wire for any existing signal. This method is known as CS ( Carrier Sense ). If two NICs sense wire on exactly same time and see no signal then both will place their signals in wire. This is known as MA (Multiple Access). If the NICs see a collision for their transmitted signals, they have to resend the signals. In this situation, each NIC that was transmit...

Patch Panel :- It is used to organize the UTP cables systematically. It doesn’t interfere in data signal. HUB and Repeater works at Layer 1 (Physical layer). These devices only understand the signals. Signals received on incoming port are forwarded from all available ports. While signals are being forwarded no other ports should receive another signals (data) form their connected devices. If other port receives signals (data) while current transmission is going on, it will create collision.

 MAU :- MAU (Multi Access Unit) is the sibling of HUB for token ring network. The only differences between HUB and MAU are :- HUB is used for Ethernet Network while MAU is used for Token ring network. HUB creates logically star topology while MAU creates logically ring topology.  

 A computer network is basically a group of multiple networking devices connected together for data sharing. Collectively networking devices have single purpose “ securely transfer data as fast as they can ”. To achieve this goal every networking device has its own functionality.
