What is Information Technology?

Information technology (IT) is the use of modern technology to aid in storage, processing, analysis and communication of information. Information can be represented in a computer in four different as follows:

a) Data

The first method presents the information in its basic and most elementary form, as a string of characters (letters and numbers). We call this data. An item of data may be a name, a price, a quantity, a code number, etc. By itself, an item of data is not of much use. It only makes sense when it is combined with other information.

b) Text

The second method presents the information written as phrases and sentences. This is called text. Although, text is much longer than basic item of data but it is much more meaningful.

c) Image

The third method presents the information in pictorial form. This includes chart, graphs, pictures and freehand drawings. This is called image. Information in this form is more comprehensive than an item of data and more meaningful.

d) Voice

The fourth method presents the information in spoken phrases and sentences. We call it voice. Like text, it is much more meaningful than an item of data.

Often we use two or more of these forms of information to convey a message. Sometimes you have to choose between alternative methods of presenting the same information. You should select the method, which most clearly and accurately represents the aspect of real world you are seeking to convey.
