This course provides a theoretical introduction to computer networks, based on the ISO/OSI Layer Model and inspired by the work of Andrew S. Tanenbaum. It explains how networks operate, from the physical layer to network applications, offering a comprehensive understanding of core concepts and technologies.

Beginning with the fundamentals of transmission systems and hardware, the course progresses through each OSI layer, integrating real-world examples and practical exercises. The content is delivered over five days, structured into five thematic units.

• Unit 1: Introduction to networking, network types, services, transmission media, and devices
• Unit 2: Data Link Layer concepts, protocols, addressing, and Ethernet standards
• Unit 3: Network Layer design, routing, addressing, and congestion control
• Unit 4: Transport Layer functions, TCP/IP protocols, and connection management
• Unit 5: Application Layer protocols, multimedia, firewalls, and cybersecurity basics
  

On completion of this course, learners will be able to:

• Define basic computer networking concepts
• Describe the components of a Data Communications System
• Identify network topologies and associated protocols
• Explain the layers and functions of the OSI and TCP/IP models
• Differentiate between network devices and their functions

• Apply basic networking protocols to support network design and implementation

• Lectures introducing networking concepts at each OSI layer
• Practical exercises and lab sessions for hands-on network configuration and troubleshooting
• Group discussions and case studies on real-world network scenarios

• Guided assignments to prepare learners for more advanced networking topics
