3. Course Description
The main emphasis of this course is on the organization and management of local area
networks (LANs). The course objectives include learning about computer network
organization and implementation, obtaining a theoretical understanding of data
communication and computer networks, and gaining practical experience in installation,
monitoring, and troubleshooting of current LAN systems. The course introduces
computer communication network design and its operations. The course includes the
following topics: Open Systems Interconnection (OSI) communication model; error
detection and recovery; local area networks; bridges, routers and gateways; network
naming and addressing; and local and remote procedures. On completion of the course,
the student should be able in part to design, implement and maintain a typical computer
network (LAN).

layered approach.
2. Implement a simple LAN with hubs, bridges and switches.
3. Describe how packets in the Internet are delivered.
4. Analyze the contents in a given Data Link layer packet, based on the layer
concept.
5. Design logical sub-address blocks with a given address block.
6. Decide routing entries given a simple example of network topology
7. Describe what classless addressing scheme is.
8. Describe how routing protocols work.
