COMPUTER NETWORKS TOPICS COVERED

Title

Unit I INTRODUCTION TO COMPUTER NETWORKS

Unit II COMMUNICATIONS NETWORK PROTOCOLS

  • Network protocol (syntax, semantics, and timing);
  • Protocol suites (OSI and TCP/IP);
  • Layered protocol software(stacks): Physical layer networking concepts;
  • data link layerconcepts;
  • network layer concepts;

Unit III LOCAL AND WIDE AREA NETWORKS

  • LAN topologies (bus, ring, star),
  • LAN technologies (Ethernet, token Ring, Gigabit
    Ethernet),
  • Error detection and correction,
  • Carrier sense multiple access networks
    (CSMA),
  • Large networks and wide areas,
  • Protocols (addressing, congestion control,
    virtual circuits, quality of service).
  • Internet – addressing,
  • routing,
  • end point control;
  • Internet protocols – IP, TCP, UDP, ICMP, HTTP, CIDR.

NETWORKS

  • Overview of the issues of network management;
  • Domain names and name services;
  • Issues for Internet Service Providers (ISPs);
  • Quality of service issues: performance,
  • failure recovery.
