This course primarily aims to acquaint the student with basic computer and communication networking technologies and the layered approach that makes design, implementation and operation of computer and communication networks possible. It also describe the complete study of OSI model which includes application layer: HTTP,FTP, SMTP, POP3, and peer-to-peer applica-tions, transport layer: UDP, TCP and congestion control, network layer: switches, routers, IP protocols and routing algorithms, link layer: error detection and correction, multiple access, MAC addressing, etc. Upon completion of this course, student should have complete knowledge about computer network related hardware and software using a layered architecture.


The objective of this course is to:

  1. Discuss the evolution of computer network concepts.
  2. Understand the structure of computer networks, factors affecting computer network deployment.
  3. Describe emerging technology in the net-centric computing area and assess their current capabilities, limitations and potential applications.
  4. Program and analyse network protocols, architecture, algorithms and other safety critical issues in real-life scenario.


At the end of course the student will be able to: 

  1. Examine and analyze various protocols like transport-layer concepts: Transport-Layer services -Reliable vs. un-reliable data transfer -TCP protocol -UDP protocol
  2. Examine and analyze the network-layer concepts like Network-Layer services –Routing -IP protocol -IP addressing
  3. Examine and analyze the different link-layer and local area network concepts like Link-Layer services –Ethernet -Token Ring -Error detection and correction -ARP protocol
  4. Analyze and implement application of network system.
