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

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

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

Let us proceed step by step.

**Explanation:**

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.
