2bit, 8bit, 10bit, 16bit
What is 2bit, 8bit, 10bit, 16bit?
2 bit (binary) means that only 2 digits are used to express numbers.
it goes same for 8,10,16.
8 bit (octect) uses 8 digits to express numbers,
10 bit (decimal) uses 10 digits to express numbers and same goes for 16(hexadecimal).
**Mistake in the picture
The picture shows each binary’s number expressing range.
10 bit is the ordinary numbers that we use.
( Of course we don’t put ‘9+3=b’ or ‘1001+11=1100’in math exam ! )
16 bit needs 16 ‘digits’ to express numbers but numbers only have 10 digits.
Therefore letter a, b, c, d, e, f is used together.
2bit | 0 | 1 | 10 | 11 | 100 | 101 | 111 | 1000 |
10bit | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
The word in Italics is where cipher increases.
For 10bit, cipher increaes after 9, because 9 is the maximum way to express number for one cipher.
Same thing goes foe 2bin. 1 is maximum way to express number for one cipher, therefore ‘0’ is added at the back.
10bit | 9 | 10 | 11 | 12 | 13 | 14 | 15 | 16 | 17 |
16bit | 9 | a | b | c | d | e | f | 10 | 11 |
The chart is comparing 10bit and 16bit.
As told before, 16bit can express from 0 to f so only after f, cipher is added.

** Back then I directly translated the knowledge I knew in Korean into English, which resulted in 2 binary, 10 binary etc (lol.. I dont think its even direct translation thinking of it now. Huge mistake)
Editied 13/2/14 : Changed ‘bin’ into ‘bit’ to make more sense.
