What is a byte?
A byte is a group of 8 bits e.g. 0011000. Bytes can be translated into decimal numbers, hexadecimal, etc. An example of the use of bytes is the input of a keyboard. The computer processes the binary input from the keyboard to text on the screen.

Define binary
Binary is a number consisting of bytes which form a sequence of on/off signals to perform certain tasks. It is the easiest and most efficient way for a computer to detect electrical signals and is the only form of code modern day processors can deal.

What is hexadecimal?
Hexadecimal is a base 16 system whereas binary is base 2 and decimal is base 10. It is relatively easy to convert binary to hexadecimal and it saves space due to the smaller number of characters it uses to express things.

What has this all got to do with the current number system?
The current number system is a base 10 system. It is relatively hard for computers to convert to binary or hexadecimal and it is useless when it comes to the processing of modern day silicon processors.
