One portion of the IP address indicates a networking and the other represents the host in a network. Each station may transmit only during its turn and may send only one frame during each turn.


Give the usage of I, S, U frames. However, no more than four repeaters may be positioned between any pairs of hosts, meaning that an Ethernet has a total questiohs of only 2,m.


Explain the timers and time registers in FDDI. So it is not recommended for large amounts of ansers. For communication, the entities must agree on a protocol. Congestion occurs because the switches in a network have a limited buffer size to store arrived packets.

Explain the two approaches of packet switching techniques. Combined station sends both commands and responses. It is the popular mechanism for continuous transmission error control. One set contains the end user portion of the HDLC frame — the logical address, control information, and data.

Discuss the basic model of FTP. Explain error control mechanism. Effect of one wire on another is called as cross talk. What is the difference between network layer delivery and the transport layer delivery? What is meant by segmentation? Routing to all neighbors.

Distinguish between peer-to-peer relationship and a primary-secondary relationship. Internet Control Message Protocol is a collection of error messages that are sent back to the source host whenever a router or host is unable to process an IP datagram successfully At the sending machine, when the message passes through the layers each layer adds the headers or trailers.


Creating a connection involves three steps: Co-ordination across the nodes of a network is necessary for an efficient communication. Beacon to determine their own absolute locations based on GPS computee manual configuration. The distance, measured in hops, from the sending bridge to the root bridge.

After the connection, all packets follow the same route and arrive in sequence. It is used in crating dynamic documents.
