INTRODUCTION OF INFORMATION TECHNOLOGY
![Page 3: Information technology and mis](https://reader034.vdocument.in/reader034/viewer/2022051710/58f04ba81a28ab1b6b8b456f/html5/thumbnails/3.jpg)
What is Information.
Information is the data processed for some purpose.
Information can only be considered to be real info if
it meets certain criteria i.e.
1. It must be communicated to the recipient
2. It must be in a language that is understood
3.It must be in a suitable form
4. It must be relevant for achieving some purpose

Information
“ Is any form of communication that provides understandable and useful
knowledge for the person receiving it.”

Information Technology“Information technology is a general term that
describes any technology that helps to produce manipulate, store ,communication information.”
"It merges computing with high speed communications links carrying data sound and video."
Examples-Telephone-Television-Appliances-Various household devices

Two different parts of information Technology
-Computer Technology"Programmable ,multiuse machine that accepts data-raw facts and figures and processes or manipulates it into information we can use ."
-Communication Technology"Also called telecommunications technology consist of electromagnetic devices and systems for communication over long distances."

Definition of Computer
"A programmable electronic device
designed to accept data, perform
prescribed mathematical and logical
operations at high speed, and display
the results of these operations."
![Page 12: Information technology and mis](https://reader034.vdocument.in/reader034/viewer/2022051710/58f04ba81a28ab1b6b8b456f/html5/thumbnails/12.jpg)
Categories of ComputerComputers are divided into five different categories.
-Super ComputersHigh capacity machines with thousands of processors that can perform more than several trillion calculations per year.
-Main FramesWater or air cooled computers more expensive and vary in size from small to medium to large depending on their use.
![Page 13: Information technology and mis](https://reader034.vdocument.in/reader034/viewer/2022051710/58f04ba81a28ab1b6b8b456f/html5/thumbnails/13.jpg)
Work StationExpensive powerful personal computers usually used for complex scientific mathematical and engineering calculations.
Micro ComputerAlso called personal computers can fit next to desk.
Micro ControllersAlso called embedded computers are the tiny specialize microprocessors installed in smart appliances

Types of Computers
There are two types of computers
- Analog Computers- Digital Computers
![Page 15: Information technology and mis](https://reader034.vdocument.in/reader034/viewer/2022051710/58f04ba81a28ab1b6b8b456f/html5/thumbnails/15.jpg)
Analog Computers-It recognize data as continuous measurement of a physical property-Its output is usually displayed on a meter or graphs-Examples are Analog clock, speed of a car thermometer etc.
![Page 16: Information technology and mis](https://reader034.vdocument.in/reader034/viewer/2022051710/58f04ba81a28ab1b6b8b456f/html5/thumbnails/16.jpg)
Digital Computers-It works with numbers-They breaks all types of information into tiny units and use numbers to represent those pieces of information-Every thing is described in two states either "on "or "off ".-They are fast and have big memory
![Page 17: Information technology and mis](https://reader034.vdocument.in/reader034/viewer/2022051710/58f04ba81a28ab1b6b8b456f/html5/thumbnails/17.jpg)
Purpose of Computer#The purpose of a computer is to process data into information
-Data consists of the raw facts and figures that are
processed into information.-Information is data that has been summarized or other wise manipulated for use in decision making
#Hardware and software
-Hardware consists of all the machinery and
equipment in a computer system-Software or programs consists of all the electronic instructions that tell the computer how to preform a task
