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:

0 0
1 1
10 2
11 3
100 4
101 5
110 6
111 7
1000 8
1001 9
1010 10
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 :-)
