Switch
Generally called as two layer switch . it performs on physical and data link layers. It is a bridge it has many ports that allow better performance. Since it is a bridge with many ports it allows allocating a unique port to each station hence each station has its own independent identity. It makes bridge performance better as it has a buffer to hold the frames for processing also it has a switching path that forwards the frame faster.

Describe Concept of Simplex, Half Duplex and Full Duplex dialogs?
The three phase of PPP session establishment are:- A. Link establishment phase B. Authentication phase C. Network layer protocol phase
An FDDI frame or Token Ring frames those points to serious problem with the ring, like a broken cable. The beacon frame carries the address of the station thought to be down.
The Address Resolution Protocol (ARP) sends out a broadcast to verify the MAC address from the IP address.
Transport Layer In computer networking it the transport layer is where sessions are exchanged between hosts. This layer resides between the application layer and networ
Retransmission of packets The disadvantage of thronging away a correctly received packet is that the subsequent retransmission of the packet might be lost or garbled and
ICMP is used to send error and control messages. Ping uses ICMP to carry the echo-request and echo-reply.
Illustrate the working of networking Bus Topology All stations attach, by appropriate hardware interfacing called as a tap, directly to a linear transmission medium, or bus. F
