bit / byte

Electronic information just like a code

(bit) Base data: information volume.
Volume of information displayed as a single binary digit in a computer
(byte) Base data: information volume.
Volume of information displayed as eight binary digits in a computer

1-byte is 256 patterns of information

The smallest unit of data handled by a computer is a straight choice between 0 and 1. This choice is repeated infinitely to express information. A one-off choice between two things is “1-bit”. When this is repeated eight times, 28 = 256 patterns of information can be displayed, and these “8-bits” are called “1-byte”.
