Packets in this technology are referred to as datagram. A CRC generator uses a modulo-2 division. The node sends a Probe frame. For communication, the entities must agree on a protocol. Switched virtual circuit Permanent virtual circuit.

What are the two categories of QoS attributes?

CS – Computer Networks – 2 & 16 Marks with answers :Study Zone

What are the network quesrions layers and the user support layers? Define a standard The three keys for understanding the algorithm are Knowledge about the neighborhood.

The idea is to take a single IP network number and allocate the IP address with that network to several physical networks, which are compurer referred to as subnets.


What are the three criteria necessary for an effective and efficient network? The third and most powerful of the redundancy checking techniques is the cyclic redundancy checks CRC CRC is based on binary division. P r i m ary station: What is meant by Concatenation? For n devices in a network, what is the number of cable links required for a mesh and ring topology? Each layer in the sending machine adds its own information to the message it receives from the layer just above it and passes the whole package to the layer just below it.

Mention the advantage and disadvantage of stop and wait flow control. Write the keys for understanding the distance vector routing. Even when one packet represents just a place of a multi packet transmission, the network treats it although it existed alone. Workstations interact with the SMTP host which receives the mail on compyter of every host in the organization, to retrieve messages by using a client-server protocol such as Post Office Protocolversion 3 POP3.

The time-to-live determines the lifetime of a packet. The transport layer creates a communication between the source and destination. The circuit is dedicated to the specific uses.


Here a sequence of redundant bits, called the CRC remainder is appended to the end of data unit. The protocol in the transport layer takes care in the delivery of data from one application program on one device to an application program on another device.


Give the essential properties for polynomial. This information is added in the form of headers or trailers. How to request Study Material? In this method, the same virtual circuit is provided between two uses on a continuous basis.

After the connection, all packets follow the same route and arrive in sequence. Specific responsibilities of data link layer include the following.

Aand short notes on CRC. Data communication is the exchange of data in the form of 1s and 0s between two devices via some form of transmission medium such as a wire cable.

Secret Key algorithms are efficient: It is a full-duplex questiohs, meaning that each TCP connection supports a pair of byte streams, one flowing in each direction.
