Solidity Programming Language – Bytes Fixed Sized Array

1 byte = 8 bit

1 hexadecimal = 4 bit

1 byte = 2 hex

Everything that will be stored in the byte array will be in the form of the hexadecimal digits.

In Solidity, you can use a fixed-size array of bytes, denoted by bytesN where N is the size of the array.

Details:

1) Byte arrays cannot be modified.

2) Padding of 0 is added at the end if the value (by which the array is initialized) does not occupy the entire space.
