Various PC Components
A PC uses a combination of hardware and software. Both hardware and software work together to perform various functions. The hardware is composed of many electronic components including all the internal (motherboard, hard disk, and power supply) and external components (monitor, keyboard, and mouse). The software refers to any set of instructions that tell the hardware what to do. Word processor, web browser, and media player are examples of software. Each component has its own function and contributes to the overall working of the system. A computer cannot function or may not work properly if we remove any component out of it. However, we can improve the performance of the system by upgrading a component with the latest one. For example, we can upgrade the RAM to improve the system performance.
