Data
Data is a collection of facts, encompassing numbers, words, measurements, observations, or descriptive content.
Data is represented as numbers stored in bytes, which, in turn, consist of bits (binary digits) with values of one or zero. The CPU processes data through logical operations to generate new data (output) from the input data.
Information
Information, in essence, is refined and timely data.
Information is also data presented within a contextual framework that imparts meaning and relevance. This contextualization enhances comprehension and reduces uncertainty.
While the terms “information” and “data” are often used interchangeably, they are not synonymous.
Types of Data
There are two fundamental types of data:
-
Qualitative Data
Qualitative data lacks numerical values and is instead expressed through natural language descriptions.
For instance: favorite color = “blue”
height = "tall"most disliked = "loryel" -
Quantitative Data
Quantitative data is numerical and is expressed without reliance on natural language descriptions.
