The goal of this course is that the student will develop an understanding of the underlying structure of networks and how they operate. At the end of this course a student should be able to:
1.Explain basic networking concepts by studying client/server architecture, network scalability, geographical scope, the Internet, intranets and extranets.
2.Identify, describe and give examples of the networking applications used in everyday tasks such as reading email or surfing the web.
3.Describe layered communication, the process of encapsulation, and message routing in network equipped devices using appropriate protocols.
4.Design and build an Ethernet network by designing the subnet structure and configuring the routers to service that network.
5.Manage network management and systems administration.
6.Construct a patch cord to connect a host computer to a network.

  1. Introduction: Data communications concepts; networking criteria; protocols & standards; standards organizations.
  2. Basic Concepts: Line configuration; topology; transmission mode; categories of network; internetworks.
  3. Reference models: The ISO/OSI model; protocol layers; the TCP/IP protocol suite and reference model
  4. Signals: Analog & digital data; periodic and aperiodic signals; simple analog signals; time and frequency domains; frequency spectrum and bandwidth; digital signals.
  5. Transmission Media: Guided media; unguided media; transmission impairment; throughput; propagation speed; propagation time; wavelength; Shannon capacity.
  6. Multiplexing: FDM; TDM; the telephone system; DSL.
  7. Error Detection and Correction: Error types; detection process; VCR; LRC CRC; checksum; error correction
  8. Data Link Control: Line discipline; flow control; error control.
  9. Mid-term
  10. Data Link Protocols: Asynchronous protocols; synchronous protocols; character oriented protocols; bit oriented protocols; link access protocols

  1. Local Area Networks: Project 802; Ethernet and its variants.
  2. Networking and Internetworking Devices: . Repeaters; routers; bridges; gateways.
  3. TCP/IP Protocol Suite: Internet Protocol; addressing; other network layer protocols (ARP; RARP;ICMP; IGMP). Transport Layer protocols (UDP; TCP).
