What
is binary ?


.  
Binary
is a base 2 number system... What does it means ? It means that after 1, there is no 2 but 10 instead. Strange ? Each binary digit is called "bit" and has a value of either "0" or "1". Note that a chain of 8 bits is called a "byte" (or "octet"). 

.  
This is the way to count up to 10 in binary:


Could you guess what is 11 in binary ?

Binary is the fundamentals of computing. Computers understand only "0"s and "1"s (which correspond to "no electrical signal" or "electrical signal"). But with that, they can do quite a lot :)
