A command is a series of step by step instructions that helps the PC perform a specific action.


The central processing unit or CPU, also known as the microprocessor or processor is the brain of the computer. It helps execute instructions in a software program and helps retrieve instructions from memory, comprehending and executing instructions, and helping direct the input and output.


The monitor or the screen of the PC against which, the operating system and access application programs, files, and documents are displayed is called the desktop.


The file is a unit for information storage that includes word-processor, spreadsheet, pictures, music, etc. Each file is differentiated with the help of a unique file name.

The system that consists of the monitor, keyboard, mouse, printer, processor, scanner, etc., is known as the hardware. When the CPU is opened, the components that make a CPU are also the hardware.


A hyperlink is a program that helps one move from one web page to another. The text is underlined and the cursor that moves over this text document, takes the shape of a hand. This means there is a hyperlink added to the text and you can click on it to move over to another page or document.
