EC2352 Computer Networks MJ2014 Question Paper
At the receiving machine, each layer removes the data meant for it and passes the rest to the next layer. It supports data rates of Mbps and provides a high-speed alternative to Ethernet and token ring access method used here is token passing.
Stations may attempt to send data multiple times before a transmission makes it onto a link. A passive hub provides a simple physical connection between the attached devices. If it dose not, a change is assumed to have occurred and the sending router then alerts the rest of the network in its next LSP.

Like Ethernet, station communicates via a common bus. What is meant by brouter? Specific responsibilities of data link layer include the following. What is mean by data communication? These allow interoperability among unrelated software system. What are the functions of a DTE?
There are 4 types of redundancy checks are used in data communication. The transport layer ensures end-to-end reliable data transmission.
What are the functions of LLC? An active hub contains a repeater that regenerates the received bit patterns before sending them out. Write short notes on VRC. What are the advantages of distributed processing?
It is the mechanism to correct the errors and it can be handled in suestion ways. How to request Study Material? What is meant by segment?
Write the questioh for understanding the distance vector routing. A frame consists of one complete cycle of time slots, including one or more slot dedicated to each sending device. Data terminal equipment is a device that is an information source or an information sink. In selective reject ARQ only the specific damaged or lost frame is retransmitted.

What is the difference between a passive and an active hub? It is similar to that of signing transactions documents when you do business with a bank.
The protocol in the transport layer takes care in the delivery of data from one application program on one domputer to an application program on another device. What is time-to-live or packet lifetime? What is selective reject ARQ? The three basic techniques of multiplexing are, Frequency-division multiplexing Time-division multiplexing Wave-division multiplexing 9.
What is meant by segmentation?
The combined station is one which acts either as a primary or a Secondary, depending upon the nature and direction of the transmission. Group the OSI layers by function. In this method, a virtual circuit is created whenever it is needed and exits only for the duration of specific exchange.
