Computer is a device that transforms data into information. Data can be anything obtained in various fields.

Input: It is the process of entering data into the computer system.

Control Unit: The process of input, output, processing and storage is performed under Control Unit. It decides when to start receiving data, when to stop receiving it, where to store data, etc.

Memory Unit: It is used to store data and instructions.

Arithmetic Logic Unit (ALU): It does addition, subtraction, multiplication, division, logic and comparison.

Peripheral Devices:

Peripheral devices are- Input Devices, Output Devices, Other Peripherals

Input devices accept data and instructions from the user. Some of the various input devices are- Keyboard, Mouse, Pen, Scanner, Touch Screen, Microphone and Track Ball.

A keyboard is the most common input device. The most commonly used keyboard is the QWERTY board.

A mouse is an electro-mechanical, hand-held device that is used as a pointer.

A pen is an input device that utilises a light-sensitive detector to select objects on a display screen.

Scanners are the devices that are used for automatic data collection.

Touch panel displays are alternatives to keyboard.

Microphone is an input device, which takes voice as input.

Trackball is a pointing device which is like a mouse lying on its back.

Monitor is the most important output device because people interact with it more intensively than others. Computer information is displayed, visually with a video adapter card and monitor.

Cathode Ray Tube Monitor is the typical monitor that you see on a desktop computer. It uses a large vacuum tube, called cathode ray tube (CRT).

Liquid Crystal Displays Monitor are also known as flat panel monitor. Most of these employ liquid crystal displays (LCDs) to render images.

Printers are used to get a hardcopy after a document is created on the computer.

A laser printer produces high quality print and it is extremely fast and quiet. An ink-jet printer creates an image directly on paper by spraying ink through tiny nozzles. In dot matrix printer the print head hits the paper through the ribbon and produces text (or images) by combinations of dots. A line printer is generally used with large computer systems to produce text-based data processing reports. Line printers are high-speed printers.

Plotters are designed to produce large drawings or images, such as construction plans for buildings or blueprints for mechanical objects. A plotter can be connected to the port normally used by a printer.

Speakers are output device, which allow you to listen to voice like music and conversation with people.

Software:

A user instructs the computer; what to do, how to do and when to do. In order to perform any task, you have to give a set of instructions in a particular sequence to the computer. These sets of instructions are called programs. Software refers to a set of programs that makes the hardware perform a particular set of tasks in a particular order.

An operating system is a system software that provides an interface for a user to communicate with the computer, manages hardware devices, manages and maintains disk file systems and supports application programs.

Computer languages are broadly classified as:

Low Level Language: The term low level means closeness to the way in which machine understand. The low level languages are Machine Language and Assembly Language.

High Level Language: It has been evolved which uses normal English like, easy to understand statements to solve any problem. Higher level languages are computer independent and programming becomes quite easy and simple.

Various high level languages are: 

BASIC (Beginners All Purpose Symbolic Instruction Code)

COBOL (Common Business Oriented language)

FORTRAN (Formula Translation)

C: Structured Programming Language

C++: Popular object oriented programming language.

The software that reads a program written in assembly language and translates it into an equivalent program in machine language is called an Assembler.
