1.5 Systems Software

In this module, we will learn about the software that enables computers to function efficiently and securely. We will investigate how operating systems and utility software work behind the scenes to manage resources, enhance performance, and maintain system stability. 

Operating systems are the backbone of any computer system – their key functions are managing memory, handling peripherals, facilitating user interactions, and organising files. From multitasking through process scheduling to securing user accounts and access rights, operating systems ensure a seamless user experience.

From here, we’ll explore utility software, focusing on tools that optimise system performance and protect data. You’ll discover how encryption safeguards sensitive information, defragmentation enhances data access speeds, and data compression saves storage space and improves data transfer efficiency.

By the end of this module, you’ll have a clear understanding of the critical role systems software plays in ensuring the smooth operation of computers.
