Discover Computer Networks

Eleanor: My name is Eleanor Abbiss and I study computer networks. It's about creating first world basic understanding so you learn about Windows and you learn about Linux operating systems. As well as creating your own networks, you each have your own pod and then you use that to configure your own network in here.

You are given a design and you need to fit all the routers and switches to that design. I love the problem solving aspect of my course. There's always issues that need to be solved and it's about figuring out how best to solve those problems, so that in the future you then "I know, I've had the problem before, I know how to fix it this time" and it's all about constantly evolving. Networking is constantly evolving.

I chose Portsmouth because it was the number one university for Computer Networks. They're building a new Cisco Suite which is great, and you'll be able to do your CCNA here as well as studying your degree at the same time. 

Your facilities

Cisco Networking Academy

Use our bespoke network laboratory with in-lab and remote access to over 200 routers and switches in a data-centre environment. The lab also has specialist dual-boot (Linux and Windows) PCs and a private cloud, for implementing and testing virtualised computing and network infrastructures.

How you'll spend your time

One of the main differences between school or college and university is how much control you have over your learning.

We use a blended learning approach to teaching, which means you’ll take part in both face-to-face and online activities during your studies.  As well as attending your timetabled classes you'll study independently in your free time, supported by staff and our virtual learning environment, Moodle.


Teaching methods on this course include:

  • lectures
  • tutorials
  • laboratory work
  • practical work

Term dates

The academic year runs from September to June. There are breaks at Christmas and Easter.
