Course objectives

The aim of the course is to expand on the knowledge of computer networks acquired on Computer Networks. Furthermore, the goal of the course is that the student understands that each network, including the Internet, is an infrastructure that serves to provide certain services. The lowest level is a classic voice transfer service, but today we are witnessing a huge number of very complex services. Emphasize that there is a whole range of services based on www technology ("service over the service"). Define and describe the Internet network, the public telephone network, the second, third, fourth and fifth generation mobile networks. Introduce students with the concept of "Next generation networks". Also look at providing broadband services such as voice, television, VoD (video on demand).

Course outcomes

• Distinguish the network from the services and identify the network as a service provider.

• Explain basic communication protocols on the Internet.
• Explain the DNS domain's architecture, explain the basic DNS function.
• Explain the GSM network architecture.
• Describe broadband services and access methods for end users.
• Argue the concept of NGN.
