Computer Networks and Data Communication

This course will cover Introduction to Networks: definition, advantages, types, configurations; The OSI/ISO reference model; Transmission media: magnetic media, twisted pair, coaxial, fiber-optics; Data encoding: straight, Manchester, differential Manchester, satellite; Digital versus Analog transmission; Modems, modulation and their standards, codes and pulse code modulation; Integrated Services Digital Networks (ISDN); Network Access Protocols; Passive versus dynamic allocation; LAN standards:802.3 (Ethernet), 802.4 (token bus), 802.5 (token ring); Computer Network security, Active and Passive Attacks; Network layer and Network layer protocols; Transport layer and Transport layer protocols. Furthermore, the course considers problems on each layer of a multilayered communication model, and describes some typical solutions to such problems.                                                                                                                                                                                                           Aims: the aims of the course are:
