State the relationship of data representation : bit, byte and character

Data Representation


1. BIT

- A short binary digit is a smallest unit of data the computer can process.
- The binary system is a number system that has jus two unique digits, 0 dan 1 called bits.
- A bit is represent by number 1 and 0
- These number represent the binary system
-These correspond to the state of on and of, true and false,or yes and no.

2. BYTE

- Byte is a unit of information built from bit
-When 8 bits are grouped together as a unit, they from a byte
- Bits and Bytes are the basic for representing all meaningfull information and programs on computer

3. CHARACTER

- One byte is equals to 8 bit
- One byte represents a single character such as the number, the letter, or sysmbol
-For example, the capital F is represented by binary coding code 01000110 that can be understood by the computer system

-Computer does not understand letter or number or pictures or symbols.
-Computer uses a binary system to count as it recognizes two states that are 0 and 1
- Number 9 is represented by binary code 00111001
- Eight bits grouped together as a unit are called a byte
- A byte represents a single character in the computer.

===========================

Computer recognizes 2 discrete: ON and OFF that represented by 2 digits, 1 and 0

8 bits = 1 byte,

8 bits = 1 character
