• 10 hrs laboratories
• 16 hrs projects

• 60 pts final exam (60 pts written part, 60 pts oral part)
• 20 pts labs
• 20 pts projects

The goal of this course is to inform students about network services and tools for network administration and traffic control. The practical parts of the course include network application programming and laboratory assignments where students can apply theoretical knowledge in configuration and analysis of real network services.

A student is able to configure network connection to the internet, configure common network services, monitor network traffic, detect and correct network failures.  He or she is familiar with modern network applications for data, voice and video transmission. A student has an overview of tools for network administration and is able to use them. He or she is capable to create a secure network connection over the internet and secure a computer against cyber threats. A student is able to program a network application.

The course introduces IT students basic principles of network communication, architecture of common Internet services, techniques for implementing network applications, and tools for network traffic monitoring and analysis.
