Data Representation
•Data refers to the symbols that represent people, events, things, and ideas. Data
can be a name, a number, the colors in a photograph, or the notes in a musical
composition.
•Data Representation refers to the form in which data is stored, processed, and
transmitted.
Number systems are the technique to represent numbers in the computer system
architecture, every value that you are saving or getting into/from computer
memory has a defined number system.
Computer architecture supports following number systems.
Binary number system
Octal number system
Decimal number system
Hexadecimal (hex) number system
1) Binary Number System
A Binary number system has only two digits that are 0 and 1. Every number
(value) represents with 0 and 1 in this number system. The base of binary number
system is 2, because it has only two digits.
