For one million users to communicate, only two million keys are needed. The system must deliver data accurately.

Explain the functions of SMTP. A device used to connect two separate networks that use different communication protocols. The dividing process is called segmentation. Give the essential properties for polynomial. A router is a single protocol or multiprotocol router that sometimes acts as a router and sometimes act as a bridge. Mention the types of error correcting methods.

One set contains the end user portion of the HDLC frame — the logical answdrs, control information, and data. Headers are added to the message at the layers 6,5,4,3, and 2. State the two kinds of events trigger a state transition? By processing the data incrementally, instead of forwarding all the raw data to the base station, the networkks of traffic in the network is reduced. Switched virtual circuit Permanent virtual circuit. The sender and the receiver expect confidentiality.


Permanent virtual circuits are comparable to leased lines in circuit switching. Stations may attempt to send data multiple times before a transmission makes it onto a link. The documents in the WWW can be grouped into three broad categories: In this method, a virtual circuit is created whenever it is needed and exits only for the duration of specific exchange. The combined station is one which acts either as a primary or a Secondary, depending upon the nature and direction of the transmission.

Domain name space is divided into three different sections: It can be implemented with each host deciding for itself whether or not to accept the message. The data must arrive at the receiver exactly as it was sent.

Workstations interact with the SMTP host which receives the mail on behalf of every host in the organization, to retrieve messages by using a client-server protocol such as Post Office Protocolversion 3 POP3. What is meant by switched virtual circuit?

CS Computer networks – RJ edition 2marks and 16marks with answers

Ethernet is a multiple-access network, meaning that a set of nodes send and receive frames over a shared link. What are the disadvantages of optical fiber as a transmission medium? The routing can be classified as, Adaptive routing Non-adaptive routing. When the size of the data unit received from the upper layer is too long for the network layer datagram or data link layer frame to handle, the transport protocol divides it into smaller usable blocks.

Define a standard What are the functions of MAC? The node sends a Probe frame. Data circuit-terminating equipment is a device used as an interface between a DTE and a network.


Otherwise, the received stream of bits is discarded and the dates are resent. What is meant by hop count? The speed of light is, however, medium dependent-electromagnetic waves traveling through copper and fiber do so at about two-thirds the speed of light in karks.

In this method, the same virtual circuit is provided between two uses on a continuous basis. What are the three pieces of information in the configuration messages? How to request Study Material? It allows additional text to include codes that define fonts, layouts, embedded graphics and hypertext links.

This strategy of doubling the delay interval between each transmission attempt is a general technique known as exponential back off. HDLC differentiates between 3 types of stations.

Headers are added to the message at the layers 6,5,4,3, and 2. If the neighborhood responds to the greeting as expected, it is assumed to be alive and functioning.

Discuss the mode for propagating light along optical channels. What are the four internetworking devices? If you use large numbers the method to be effective.
