Computer Hardware and Software Components

Software: Programs and Operating Systems

The machine consists of hardware capable of performing a variety of tasks. Electronic computer components need software to run. The programs will help us process information.

We need to keep an operating system running, which allows software to process information using physical components.

Software Categories

• Operating system — manages hardware and provides services for applications.
• Application software — processes personal and end-user information.

Physical Components (Hardware)

Physical components include:
