Course overview
The aim of this module is to enable students to learn to understand how network communication is achieved, and how to implement a functional SOHO (Small Office Home Office) computer network
Students will learn:
• To recognize key elements of computer network architecture
• Terminology and technologies used in computer networks
• How to use referent models to explain communication in the network
• How to use tools for analyzing network traffic
• To create and address a scheme for a small network
• To choose equipment for a small network
• How to implement a small network in a network simulator
• To recognize network security features
• To recognize Wireless network communication role in modern network
This module is important to support students understanding of how to enable communication between devices in the network functions. For this purpose, the OSI model is used to explain all the necessary steps in establishing, maintaining, and closing the communication between devices in the network. This is the first module where students have the opportunity to use tools and commands to interact with other devices in the network and analyze network communication as well as use a network simulator to implement a functional SOHO (Small Office Home Office).
Content
In this course, students are introduced to general architecture and key characteristics of computer networks as well as network terminology, technologies, and tools typically used in computer networks. For explaining technologies, their interdependencies, and generally how network communication occurs the 7 layer OSI (Open Systems Interconnection) model is used. Special attention is given to transport, network, and data-link layers and underlying mechanisms that make communication over the network possible. The main focus is to learn through analyzing network traffic and interpreting what is happening on the network and why as well as hands-on labs and work process documentation by students. At the end of the course, students will be able to create a small network with an addressing scheme and explain what are the key elements of a secure network environment and how wireless networks are used today.
