Data Communications

The Introduction to Data Communications course provides students with a comprehensive understanding of fundamental concepts, technologies, and protocols used in modern data communication systems. The course explores the principles underlying the transmission, reception, and processing of digital data over various communication mediums, including wired and wireless networks. Through lectures, hands-on lab exercises, and real-world case studies, students will gain practical skills in designing, implementing, and troubleshooting data communication systems.

Course Objectives:Understanding Data Communication Fundamentals: Students will learn the basic principles of data communication, including data encoding, transmission modes, signal modulation, and multiplexing techniques. Network Architecture and Protocols: Students will explore the architecture and components of computer networks, including the OSI and TCP/IP reference models. They will also study key networking protocols such as Ethernet, TCP, IP, and UDP.

Wired and Wireless Transmission Media: Students will examine different types of transmission media, including twisted pair, coaxial cable, fiber optic cable, and wireless technologies. They will learn about the characteristics, advantages, and limitations of each medium. Networking Devices and Technologies: Students will gain hands-on experience with networking devices such as routers, switches, hubs, and access points.

They will also explore network topologies, addressing schemes, and subnetting techniques. Data Link Layer Protocols: Students will study data link layer protocols such as HDLC, PPP, and Ethernet. They will learn about frame formats, error detection and correction techniques, flow control mechanisms, and media access control methods.
