A good explanation for binary is light bulbs. If I have one light bulb outside my house I can send two
messages , if it’s on I am in , if it’s off I am out. With 2 light bulbs I can have both on, both off the left on and the right off and vice versa , so I can send 4 different messages. If I had 8 light bulbs I can send 256 messages with different bulbs on and off. These messages can be the letters of the alphabet, the numbers , special characters and instructions like add , compare, multiply etc. instead of light bulbs on and off use electrical elements which are positively or negatively charged. Each of the elements is called a binary integer or bit for short. 8 bits are called a byte ( a word invented by IBM which they claim is the only worthy have ever invented)
