This course describes the concepts related to communication and a data communication network, information transfer process, network devices and their functions, network types, and typical networking. in addition, this course briefly introduces the concepts related to network engineering and network engineers.

4 2 Computer Network Data Communication Pdf Network Topology 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 computer network, often simply referred to as a network, is a collection of hardware components and computers interconnected by communication channels that allow sharing of resources and information. 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. 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.

Data Communication And Networks Pdf Computer Network Internet 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. 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. 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. 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. 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. Separation of the pure communication aspects of the network (the subnet) from the application aspects (the hosts), greatly simplifies the complete network design.
