Data Communication And Computer Network Pdf Pdf This document introduces the fundamentals of data communications and networking, covering essential topics such as data representation, data flow, computer networks, protocols, and standards. A virtual circuit network is normally implemented in the data link layer, while a circuit switched network is implemented in the physical layer and a datagram network in the network layer.
4 2 Computer Network Data Communication Pdf Network Topology Show clear understanding of the basic concepts of data communications including the key aspects of networking and their interrelationship, packet switching, circuit 1 switching and cell switching as internal and external. Wide area network: a wan may be defined as a data communications network that covers a the relatively broad geographic area to connect lans between different cities with the help of transmission facilities provided by common carriers, such as telephone companies. The network layer provides for the transfer of data in the form of packets across the communication networks. it establishes, maintains, and terminates logical and physical connections across multiple interconnected networks. Course outcomes: understand the basics of data communication, networking, internet and their importance. analyze the services and features of various protocol layers in data networks. differentiate wired and wireless computer networks analyse tcp ip and their protocols.

A peer to peer network is one in which two or more pcs share files and access to devices such as printers without requiring a separate server computer or server software. Network security issues include protecting data from unauthorized access, protecting data from damage and development, and implementing policies and procedures for recovery from breaches and data losses. Separation of the pure communication aspects of the network (the subnet) from the application aspects (the hosts), greatly simplifies the complete network design. By computer network we mean an interconnected set of autonomous computers. the term autonomous implies that the computers can function independent of others. however, these computers can exchange information with each other through the communication network system.
