COMPUTER HARDWARE
Computer hardware refers to the physical, tangible components of a computer system. It is divided into internal components (like the CPU, motherboard, and RAM) that process data, and external peripherals (like keyboards, mice, and monitors) that allow you to interact with the machine. [1, 2, 3]
The fundamental parts making up a computer system include:
- Central Processing Unit (CPU): The “brain” of the computer that executes instructions and performs calculations.
- Motherboard: The primary circuit board that connects the CPU, memory, and all other components together.
- Random Access Memory (RAM): Temporary volatile memory used by the CPU to store data currently in active use.
- Storage (SSD/HDD): Non-volatile devices used to persistently store software, files, and operating systems.
- Graphics Processing Unit (GPU): Specialized hardware that renders images, videos, and 3D graphics.
- Power Supply Unit (PSU): Converts electrical power from an outlet into a usable form for the computer’s parts.
- Input/Output Devices: Components like monitors for visual display, and keyboards or mice for user commands. [1, 2, 3, 4, 5]

COMPUTER SOFTWARE
Computer software is the intangible set of instructions that tells a computer’s physical hardware how to operate and perform specific tasks. Without it, a computer is just a useless collection of metal and plastic. Software translates human commands into machine-readable actions. [1, 2, 3, 4, 5]
- System Software: The foundational layer that manages hardware resources and provides a platform for other programs. This includes Operating Systems (such as Windows, macOS, and Linux), as well as device drivers and utility tools. [1, 2, 3]
- Application Software: Programs designed to help users perform specific daily tasks. Common examples include web browsers (like Chrome), productivity suites (like Microsoft Office), and graphic design programs. [1, 2]
