Data Communication 1

Upon completion of the course, students will be able to:

• Describe the history and development of systems for data communication seen from a local, global and scientific perspective
• Describe all layers in the OSI and TCP / IP model and the application areas of the layers
• Describe the most common application storage protocols and their application areas
• Describe the structure and areas of application of the Ethernet protocol
• Describe common types of security threats to local networks and possible countermeasures against them
• Apply decimal, binary, and hexadecimal systems and convert between them
• Harden basic network equipment to strengthen the security of these
• Apply IPv4 / IPv6 when designing IP address schemes for medium sized local area networks
• Design and implement infrastructure for medium sized local networks and perform troubleshooting of  these
• Use various tools  to test network connections

The course introduces architectures, models, protocols and network elements that connect users, devices, applications and data via the Internet and over modern data networks. The principles of IP addressing and the basics of Ethernet concept, media and basic configuration of network devices are introduced to create a basis for a sound understanding of the concept of data communication. The course also provides a basic introduction to methods for testing network connections and suitable tools for this. Furthermore, the course provides the basics of network security where common threats are highlighted as are various methods we can apply to meet these threats and strengthen the protection of infrastructure, communication units and data / information.

The course contains ongoing practical elements for managing and configuring communication equipment in the form of routers and switches.
