| BIT | BYTE |
|---|---|
| A bit is the smallest unit of data in a computer. | A byte is a unit of digital information that most commonly consist of eight bits. |
| It was invented by Basile Bouchon in 1956. | It was invented by Werner Buchholz in 1956. |
| Bit is represented as either 0 or 1. | Byte is used to represent alphanumeric characters in the form of bits. |
| It is denoted with lower case letter b | It is denoted with upper case letter B |
| Range is 0 or 1. | Range is -128 to +127. |

What is the meaning of the word bit?
The word bit is short for binary digit.
The word bit is short for binary digit.
Why bit is important?
The bit is so important because it describes the point at which the software (instructions) meets the hardware (machinery).
What is the meaning of the word byte?
The word byte is the smallest addressable unit for CPU.
Why byte is important?
The byte is measuring how many numbers a computer or a electronic device can hold.
How many bits in a byte?
Standard number of bits in a byte in eight.
Where do bits and bytes store?
Bits and bytes are stored on hard drive.
What is a hard drive?
A hard disk drive is a device that permanently stores and retrieves data.
Purpose:
Smallest unit of storage.
It stores just 0 or 1.
In chip electric charge = 0/1.
Eg: 01011010
What is 0 or 1:
0 represents false.
1 represents true.
Conversion of bytes to bits:
A much easier way to get these conversions is to use a calculator like a Bit calculator.
Bytes to Bits
Bytes to Bits
Bit calculator:
Used to convert file storage size from one unit of measurement to another.
Examples:
- Bit string is 1001110010101110 would be partitioned as 1001 1100 1010 1110 and thus written in compact form.
- Letter A would be 01000001 KJW would be 010010110100101001010111 to make it easier comma after every four digits is called nibbles 0100,1011,0100,1010,0101,0111.
- 4B4A5700 is easier to understand than 0's and 1's.
What is a nibble?
A nibble is half a bit or 4 bytes.
What is octet?
Used to store eight bits.
Applications in daily life:
- The telephones and mobiles we use to make a call over huge distances could not taken shape with out electromagnetism.
- Conventional light switch. on or off no intermediate state or the numbers 1 and 0.
- The loud speaker which we use for public announcements in meetings, or transmit message to a long distance is a electromagnetic appliance.
