Bit: English bit, is a state of a computer transistor (power-on and power-down). is 0 and 1, true and false, is the most basic computer transmission unit.
Example:
2bit:10;
4bit:1111;
8bit:1111 1111;
BYTE: English byte
1. is a measurement unit of computer information technology used to measure storage capacity
1B (Byte) = 8bit;
1KB = 1024B (Byte);
1MB = 1024KB (Byte);..
2. Conversion
1 B = 8bit
1 B = 1111 1111
1 B = 0 to 255
1 B = 128 to 127
Characters: in computer and telecommunications technology, a character is the basic information for a unit of a glyph, a glyph unit, or a symbol.
ASCII encoding an English letter (not case) occupies a byte of space, a Chinese character occupies two bytes of space.
In GB 2312/GBK encoding, a Chinese character store requires 2 bytes.
In UTF-8 encoding, an English letter character store requires 1 bytes, and a Chinese character store requires 3 to 4 bytes
