Masters degrees in Operating Systems (OS) equip postgraduates with the advanced techniques to manager and design software to facilitate the efficient use of system components (programmes, processes etc.).
Taught MSc degrees are typical for the field, though research-based MRes and MPhil programmes may also be available at some institutions. Entry requirements normally include a relevant undergraduate degree such as IT or Computer Science.
You will develop techniques in programming, algorithmics and cryptography (coding) to design and model basic and advanced Operating Systems and their functions. This includes observing input from interfaces such as keyboards, sending output to display screens, tracking files and directories, and controlling peripheral devices such as printers.
Techniques in the field can be applied to a range of operating systems, from games console design and mobile technologies, to web servers and even super computers. So, you could essentially work with NASA.
As well as working with individual organisations, you could aspire to set up your own business, providing advice and services to other companies. Your expertise would also make you suited to cyber security control on local, national or even global scales.
