Course Content
Overview of communications industry. Use of systems to create, process, transmit, receive and evaluate
information. Basics of making computers communicate and how various signals are converted for data
transmission, with introduction to LAN/WAN.

Course Description

This course builds a student’s knowledge of related software and hardware. Introduces the technology of
network architecture, packet switching, data communications channels, and data communication devices.
Also Link Layer protocols, Local Area Networks, and Wide Area Networking issues, including routing and
flow control.

Course Objectives
The objective of the course is to expose students to basics of telecommunication. At the end of the course
students will
1. explain why networks are structured the way they are today,
2. appreciate the need for data communication standards and protocol architectures.
3. understand communication signals and their transmission over various media.
4. understand requirements to get two computers to communicate digital data reliably.
5. Become familiar with communication channels.

Course Requirements
Students are expected to have a strong mathematical background and an understanding of probability
theory. Also they are expected to attend 75% of the classes before they can sit for the examination. It is
compulsory for all students to submit their assignments in word processed form.
