What you'll learn

Each question helps you build key knowledge and skills.

  • 1An operating system is the main piece of software that manages a computer, letting the user interact with the hardware and run other programs like games or word processors.
  • 2The operating system manages memory and processes, deciding which programs get to use the CPU and RAM at any moment so several tasks can seemingly run at once.
  • 3It also manages files and users, organising data into folders and controlling who is allowed to access which files on a shared computer.
  • 4Device drivers are small pieces of software that let the operating system communicate properly with hardware such as printers, mice and graphics cards.
  • 5Utility software helps keep a computer running smoothly, for example antivirus software, disk cleanup tools and file compression tools, and software can be open source and free to change, or proprietary and owned by a company.
