Computer runs with two basis:
1) Computer Hardware
2) Computer Software
Computer Hardware:
Hardware are those parts of computer which can be physically touched seen and cab be carried from one place to another(e.g)keyboard, mouse, monitor, CPU, printer, scanner. etc.
keyboard is used to insert input(TEXT) data into computer.
In computing, a mouse is a pointing device that detects two-dimensional motion relative to a surface. Means a mouse has a pointer which moves on screen and makes the work easy.
A monitor or a display is an electronic visual display for computers. The monitor comprises the display device, circuitry and an enclosure. The display device in modern monitors is typically a thin film transistor liquid crystal display (TFT-LCD) thin panel, while older monitors used a cathode ray tube (CRT) about as deep as the screen size.
CPU is the abbreviation for central processing unit. The CPU is the brains of the computer where most calculations take place.
Computer Software:
Software is that part of computer that operates the hardware. Software cannot be touched like hardware. It is a written language of commands in programming which commands the hardware to perform a particular task. Computer Software is called the Operating System. because without a OS a computer does not run even cannot start. Software is usually written in programming language that are easier and more efficient for humans to use than machine language.
