Intended Learning Outcomes (ILOs)

What is the main purpose of this course?

This is an introductory course to Computer Networks. During the course, we will introduce the fundamental principles behind modern computer networks, including the OSI reference model, the fundamental communication protocols, network topologies, and peer-to-peer and client-server architectures for network applications. We will also cover the basic C functions for network programming, as well as software tools to monitor data packets in a network, the configuration of routers and routing algorithms. We will conclude the course with covering the modern problems of existing computer networks, including the security aspects.

ILOs defined at three levels

Level 1: What concepts should a student know/remember/explain?

By the end of the course, the students should be able to ...

  • Layered structure of a computer network
  • Topologies in computer networks
  • Addressing schemes in networks
  • Routing algorithms
  • Security at different TCP/IP layers
  • Nuts and bolts of applications in networks

Level 2: What basic practical skills should a student be able to perform?

By the end of the course, the students should be able to ...

  • How a network is formed
  • How addressing is done at different layers of the networks
  • How subnets are created
  • How different routing protocols work and which one is better in which scenario
  • How medium is accessed on a network
  • How different networks operate
  • And Demonstrate the knowledge and discuss the overal functioning of a computer network

Level 3: What complex comprehensive skills should a student be able to apply in real-life scenarios?

By the end of the course, the students should be able to ...

  • Configure networks
  • Configure routing
  • Perform TCP and UDP connections
  • Create networks and subnets
  • Write simple network applications through sockets

Grading

Course grading range

Grade Range Description of performance
A. Excellent 90-100 -
B. Good 70-89 -
C. Satisfactory 60-69 -
D. Poor 0-59 -

Course activities and grading breakdown

Activity Type Percentage of the overall course grade
Regular Quizzes (During lectures, tutorials, or labs) 5 (excluding 3 worst)
Midterm Exam 20
Final Exam 60
Labs/seminar classes 15

All labs must be delivered by a specified date, before the exam date, otherwise the course is failed; late labs delivery without justifying reasons is penalised.

Failing any part of the evaluation (that is scoring less than 60%) will trigger a failure in the entire course (midterm is an exception). If there are no failed components, then the final grade is computed as a weighted average of the components listed above approximated at the highest second digit and then rounded to the closest integer.
