The Computer: Hardware And Software System - SS3 Accounting Lesson Note

A computer is a device that can be used to process and manipulate information. It consists of two main components: hardware and software.

Hardware refers to the physical components of a computer, such as the central processing unit (CPU), random access memory (RAM), hard disk drive (HDD), motherboard, and peripherals like keyboard, mouse, and monitor. These components work together to receive, store, process, and output data.

Software refers to the programs, applications, and operating systems that run on a computer. Software is a set of instructions that tells the hardware what to do. It includes system software, like the operating system (e.g. Windows, macOS, Linux), which manages the computer's resources, and application software, like Microsoft Office, Photoshop, and web browsers, which are designed for specific tasks.

The hardware and software of a computer work together to process and manipulate data. The hardware provides the physical infrastructure for data processing, while the software provides the instructions and commands that tell the hardware what to do.
