Description

A comprehensive course that explores the principles, concepts, and protocols underlying the design, implementation, and management of modern computer networks. In an increasingly connected world, computer networks play a vital role in facilitating seamless communication and data exchange. This course covers the fundamental components, functionalities, and protocols used in local area networks (LANs), wide area networks (WANs), and the Internet.

Topics covered include network architecture, network models, network protocols, network security, network performance, and network management.

The learners' will be able to understand and explain the following upon completing this course:

1. Fundamentals of Networking - Network Criteria, Types, Basic Parameters.

2. Network Topologies - Types of Connection, Mesh, Star, Ring, Bus Topologies.

3. The responsibilities of all the layers of OSI Model and the TCP/IP Model.

4. Line Coding Techniques - Unipolar NRZ, Polar NRZ, RZ, Bipolar, Biphase Schemes.

5. Error Detection Techniques - Parity, LRC, CRC, VRC, Checksum.

6. Switching Techniques - Circuit Switching, Packet Switching and VCN.

7. Flow Control Techniques - Stop and Wait, ARQ, Sliding Window Protocols.

8. Multiplexing Techniques - TDM, FDM, WDM

9. Addressing - IPv4, IPv6, IPv4 Header Format.

10. Network Devices - Passive Hubs, Active Hubs, Repeaters, Bridges, Routers
