CS331: Data Communications and Computer Networks

About This Course

This course covers the basics of data communication and computer networks. Topics include the fundamentals of data communication, computer network characteristics, ISO-OSI protocol layers, network topologies and models, error detection and correction methods, and key factors affecting network performance

Key Points

Understand how communication works in data networks and the Internet using OSI and TCP/IP models.
Explain the services, features, and devices used in each layer of the TCP/IP model.
Create a network design to solve real-world networking problems.
Design, calculate, and apply subnet masks and IP addresses to meet network needs.
Use tools like Cisco Packet Tracer and Network Protocol Analyzers (NPA) for simulations and network analysis.
