1. Brief description and aims of module:

This module introduces the technologies and protocols of computer networks. You learn about the core duties of a network administrator, how to build networks using standard devices and interconnect, and how to configure and maintain networks using software tools. Gaining practical experience working with network technologies and architectures is an essential first step towards being able to protect data from unauthorised access. After this module you will be in a better position to identify and address network vulnerabilities, as engage strategies for defending computing systems in modern organisations.

We begin by reviewing the basics of computer network types and typologies, as well as the TCP/IP and OSI (Open Systems Interconnection) reference model. From here you learn best practice for designing, configuring and optimising small-scale computer networks using standard simulation software and physical devices. This begins with a SOHO (small-office-home-office) setup to morel complex configurations for larger enterprises. Some key network security controls are also covered in this module, however deeper interaction with this topic is covered later in the programme. The key here is to ensure that you understand computer networking from a practical perspective, including how data is packaged and transported from point A to point B.
