Example 1
easyWhat is an operating system and name three things it manages.
Solution
- 1 Step 1: An operating system (OS) is software that manages computer hardware and provides services for applications. Examples: Windows, macOS, Linux, Android, iOS.
- 2 Step 2: It manages: (1) Memory — allocating RAM to programs. (2) Processes — running multiple programs and sharing CPU time. (3) Files — organising data on storage devices with folders and permissions.
- 3 Step 3: The OS acts as an intermediary between applications and hardware. Programs do not interact with hardware directly — they ask the OS, which handles the details.
Answer
An OS manages hardware resources for applications. It manages: memory allocation, process scheduling, and file systems.
The operating system is the most important software on a computer. Without it, each application would need to handle hardware details directly, making software development extremely complex.
