Information

Technology

A set of tools that enables us to work with information

Facts presented in a meaningful fashion.

  • Software

  • Application software e.g.MS-office S/W, media software, business software

  • System software e.g. operating system software, utility software

  • Hardware

  • Input devices

  • Output devices

  • Telecommunication devices

  • Storage devices

Personal Computers

Wireless Networks

Satellites

Cellular technology

videoconferencing

Internet


Information technology1

Information Technology

Technical definition:

“The capability to electronically input, process, store, output, transmit, and receive data and information, including text, graphics, sound, and video, as well as the ability to control machines of all kinds electronically.”


Information technology2

Information Technology

  • Technology

  • A set of tools that enables you to work more efficiently and effectively with information

  • Rationally speaking people and information are the most important resources within MIS, not Technology

  • Most of organizations need all three.


Understanding your computer

Data

The raw facts and figures that are processed into information

Information

Data that has been summarized or otherwise manipulated for use in decision making

Understanding Your Computer

The purpose of a computer is to process data into information.


What is data

What is Data?

Definition-1:

“A collection of raw facts that describes a phenomenon”

Examples

  • Current temperature

  • Price of a movie rental

  • Your age etc.

    Definition-2:

    “A message which source wants to communicate to the receiver”

    e.gText, Voice, Image, movies, Music etc


What is information

What Is Information?

Definition:

  • It has the particular meaning within a specific

    context

  • Every surprising/new thing is information

  • Reduction of redundancy in data

    • For example if you are trying to decide what to wear, the current temperature is information because it is logical help to your decision.


Data vs information
