# What is the highest decimal value you can have for one byte?

**Solution:**

A byte consists of 8 adjacent binary digits (bits), each of which consists of a 0 or 1.

As we know there are 8 bits in one byte.

So the largest value can be calculated by using 2n - 1, where n is the number of bits.

2^{8} - 1 = 255.

Hence 255 is the highest decimal value you can have for one byte.

## What is the highest decimal value you can have for one byte?

**Summary:**

255 is the highest decimal value you can have for one byte.
