Computer Networks Guidelines and Practical List
Course Objective: This course covers the concepts of data communication and computer networks. It comprises of the study of the standard models for the layered protocol architecture to communicate between autonomous computers in a network and also the main features and issues of communication protocols for different layers. Topics covered comprise of introduction to OSI and TCP/IP models also.
Computer Networks Guidelines
Introduction: Types of computer networks, Internet, Intranet, Network topologies, Network classifications.
Network Architecture Models: Layered architecture approach, OSI Reference Model, TCP/IP Reference Model.
Physical Layer: Analog signal, digital signal, digital modulation techniques (ASK, PSK, QAM), encoding techniques, maximum data rate of a channel, transmission media (guided transmission media, wireless transmission, satellite communication), multiplexing (frequency division multiplexing, time division multiplexing, wavelength division multiplexing).
Data Link MAC Layer: Data link layer services, error-detection and correction techniques, error recovery protocols (stop and wait, go back n, selective repeat), multiple access protocols, (TDMA/FDP, CDMA/FDD/CSMA/CD, CSMA/CA), Datalink and MAC addressing, Ethernet, data link layer switching, point-to-point protocol.
Network layer: Networks and Inter networks, virtual circuits and datagrams, addressing, sub netting, Routing- (Distance vector and link state routing), Network Layer Protocols- (ARP, IPV4, ICMP, IPV6).
Transport and Application Layer: Process to process Delivery- (client server paradigm, connectionless versus connection oriented service, reliable versus unreliable); User Datagram Protocols, TCP/IP protocol, Flow Control.
Protocols: FTP (File Transfer protocol), SMTP (Simple, Mail Transfer Protocol), Telnet and remote login protocol, WWW (World Wide Web), HTTP (Hyper Text Transfer protocol), Uniform Resource Locator, HTML and forms.
