When we input a value into the computer, the keyboard will send messages to the processor of the computer in a series of 1s and 0s. And then the processor will put and output on the computer screen. Binary is a Base 2 language, meaning it has a variety of 2 different characters which it accepts, as compared to decimal or denary which uses 10 characters.

4 bits of Binary is 1 bit of Hexadecimal. Hexadecimal is a base 16 number system, which is used to simplify large binary code. This makes it easier for a 32-bit binary processor to compute a value, as it is being simplified into lesser bits.

So how would you convert binary to hexadecimal:

 

Then how would this apply to numbers and letters in binary specifically:
