Question

Noobie Question Here. I always see the number 255 in computer science. Is there are specific reason why?

Answer 1

any*

Answer 2

Any character or number is stored in bytes of memory.
1 byte is made of 8 bits.

2 2 2 2 2 2 2 2 ( either of the 2 binary no.s 0 or 1 can be occupied by each
- - - - - - - - of the 8 bits)

So, total no. of Numbers that can be stored in 8 bits
2*2*2*2*2*2*2*2= 256

Any of these 256 numbers can be stored in 1 byte.
Since the number has to start from 0, the range is 0 to 255

Answer 3

Thank you that's a really good answer.
