Computer is a device that accepts digital data as input, manipulates it based on a program's instructions, and provides processed results as output. It has two main parts: hardware and software. Hardware are the physical and tangible parts like the keyboard, monitor, mouse, and central processing unit. Hardware is divided into input devices to feed data, storage devices to store data, and output devices to display or print data. Software includes the operating system and programs that tell the computer what to do. Common system software includes Windows and Linux, while application software includes programs like Word and Excel.

An input device is a hardware or peripheral device
used to send data to a computer. An input device
allows users to communicate and feed instructions
and data to computers for processing, display
and/or storage.
Examples of Input Devices
 Keyboard.
 Graphic Pad.
 Webcam
 Mouse.
 Scanner.
 Joystick.
 Track Ball.
 Digital Camera.
 Microphones.

7. OUTPUT DEVICES
 An output device is any piece of computer
hardware equipment which converts information
into human-readable form.
 An output device can receive data from another
device and generate output with that data.
Examples include monitors, projectors, speakers,
headphones and printers.

instructions and its associated documentations that
tells a computer what to do or how to perform a
task. Software includes all different software
programs on a computer, such as applications and
the operating system.
 Software can be divided in to two categories:
1. System Software
