Intended learning outcomes

The course aims at provide the participants with comprehensive knowledge in data communications with focus on the IP protocol, the data link layer, and communication protocols for wireless and mobile networks. Moreover, the course is intended to let the participants gain practical skills in setting up computer networks. Most of today’s data communication uses the Internet. New applications appear constantly. The course deals with the key technologies used by the Internet, and how new communication solutions can be formed using the Internet as the infrastructure. The course focuses on techniques and protocols at the network communication model.
After completing the course, the participants are expected to be able to

  • Identify the connections between the course subjects and their study program, and thereby justify the learning of these subjects.
  • Identify the most essential components in building wired and wireless networks.
  • Describe the functions of the layers in the model.
  • Tell the differences between various routing protocols and algorithms
  • Compare and explain the application areas of various protocols at the data link layer
  • Associate various concepts, components, techniques, and functions to layers
  • Describe techniques that are used to implement Internet access via wireless networks
  • Describe the impact of wireless links on the protocols used by the Internet
  • Explain the underlying concepts and common solutions for service quality.
  • Explain the possibilities and limitations of the Internet for real-time communications.
  • Design and configure networks, and assess network performance.
  • Analyze and evaluate data communication solutions based on in-depth knowledge in protocols and the Internet.
