Data is a collection of raw facts, figures or instructions that do not have much meaning to the user.
Data may be in form of numbers, alphabets/letters or symbols, and can be processed to produce information.
TYPES OF DATA.
There are two types/forms of data:
a). Digital (discrete) data:
- Digital data is discrete in nature. It must be represented in form of numbers, alphabets or symbols for it to be processed by a computer.
- - Digital data is obtained by counting. E.g. 1, 2, 3 …
b). Analogue (continuous) data:
- Analogue data is continuous in nature. It must be represented in physical nature in order to be processed by the computer.
- Analogue data is obtained by measurement. E.g. Pressure, Temperature, Humidity, Lengths or currents, etc
- The output is in form of smooth graphs from which the data can be read.
- It is the process of collecting all items of data together & converting them into information.
- Processing refers to the way the data is manipulated (or handled) to turn it into information.
- The processing may involve calculation, comparison or any other logic to produce the required result. The processing of the data usually results in some meaningful information being produced.
