• Binary is the basic function of the computer.  The 1's indicate a High state and 0's indicate a Low state. The high and low states refer to the voltage level of the memory.  Memory can be either short term memory or it can be long term memory depending exactly where it is in the system.

Hexadecimal is just another method of expressing the numbers.  Hexadecimal 51 is the same as 1010001 binary.  It's just 2 different ways of expressing the same value.

• Hi CoreyPlayzYT,

Based on my search and knowledge, Binary numbers – seen as strings of 0's and 1's – are often associated with computers. The binary system was chosen only because it is quite easy to distinguish the presence of an electric current from an absense of electric current, especially when working with trillions of such connections. And using any other number base in this system ridiculous, because the system would need to constantly convert between them.
