Study Notes
What is a Computer?
- A computer is a complex machine comprising hardware (physical components) and software (instructions)
- Software requires a way to interact with hardware and manage its resources efficiently
Why do we need an Operating System?
- Without an OS, direct interaction with hardware for every task would be necessary, making it incredibly complex and impractical
- An OS acts as an intermediary, providing a layer of abstraction that simplifies interaction with the computer
Fundamental Responsibilities of an Operating System
- Process Management: creates and manages running programs (processes)
- Memory Management: allocates memory for running programs and data
- Storage Management: provides access and organization for data on storage devices
- Input/Output (I/O) Management: controls how programs interact with peripherals (keyboard, mouse, printer)
- Security: protects the system from unauthorized access and malicious software
How an OS Achieves its Responsibilities
Process Management
- Assigns CPU time fairly to different programs
- Schedules program execution
- Handles program termination
