This document provides an introduction to information technology and computers. It discusses key topics such as: - Information technology is the use of technology to store, retrieve, transmit, and manipulate data or information. - The basic parts of a computer are the central processing unit, monitor, keyboard, and mouse. Input devices such as keyboards are used to send data to computers, while output devices like monitors are used to display information. - Hardware refers to the physical parts of a computer system, while software includes programs and instructions that control the hardware and allow it to perform tasks. There are various types of computers including desktops, laptops, tablets, and smartphones.

Basic Parts of Computer
CPU Central Processing Unit
Monitor ,LCD, LED Output Device
Key board Input Device
Mouse Input Device

7.  An Input device is any Hardware device that
sends data to a computer, allowing you to
interact with and control it.
 Example:
 Keyboard
 Mouse
 Mike
 Joystick

8.  Output Devices use for shown the different information
or result of the computer when we work on computer.
There are many types of output devices.
 It is usually used for display, Projection or physical
reproduction.
For Example:-
Monitor, Printer, Speaker etc.

9.  Data is collection of facts or figures. The data is a
raw material to be processed by a computer
 Data is divided into 5 types

Hardware
Computer hardware is the collection of physical parts of a
computer system. This includes the computer case, monitor,
keyboard, and mouse.
It also includes all the parts inside the computer case, such as
the hard disk drive, motherboard, video card, and many others.
Computer hardware is what you can physically touch.
For Example
Mouse, Keyboard, CPU, LCD OR Monitor

Software:-
Software is a set of instruction that perform particular
task. And all program of computer that we can operate on computer
is called software.
Software use to control operate and instruct to computer hardware.
There are two(2) types of software.
I. System Software
II. Application Software

 Personal computer: A small, single-user computer based on a
microprocessor.
 Workstation: A powerful, single-user computer.
 A workstation is like a personal computer, but it has a more
powerful microprocessor and, in general, a higher-quality monitor.

 Laptop
 Tablet
 Smartphone

16. 16
 There are three Types of Computer
 Analog
 Digital
 Hybrid

17.  An analog computer is a form of computer that uses
the continuously changeable aspects of physical
phenomena such as electrical, mechanical, or
hydraulic quantities to model the problem being
solved.

19.  Digital computer, any of a class of devices
capable of solving problems by processing
information in discrete form.
 It operates on data, including Numbers, letters,
and symbols, that are expressed in binary code—
i.e., using only the two digits 0 and 1

21.  Hybrid computers are computers that exhibit features
of analog computers and digital computers.
 The digital component normally serves as the
controller and provides logical and numerical
operations, while the analog component often serves as
a solver of differential equations and other
mathematically complex equations
