Question

Does the number 255 hold any special significance to computer coders?

Answer 1

Yes, programmers uses it. it's related to storage procedure.

Codes and colors values are stored in bytes generally.

2^8 bit / byte= 256

if we count it from 0 then it'd be

0-255

and 255 is largest place(or number) for codes that can store bytes(or bit)

These words in written in my book for number 255 in computer

255 is the largest number that can be stored in a single (8-bit) byte of computer memory
