The Keyto Binary Numbers and
Computing
First, some key terms:
Computer
Bits
Bytes
Binary Counting
Decimal
What is a Computer?
Simply put,
a machine that flips binary digits
on and off.
Bits and Bytes
A bit is a single binary digit. (This is a useless amount of information)
But, when you group them together and have 8 bits,
this makes 1 byte.
Bits and Bytes
A single byte can have up to 256 different combinations
of 1s and 0s.
Typically information is broken up into bytes to be
stored, calculated, or transmitted.
Binary Counting
We count by using the numbers 0 through 9.
Then when we start all over again, we put a 1 for the first digit
and increment the second digit from 0 to 9 again.
Binary Counting
The same goes for binary, except that we can only use the
numbers 0 through 1.
Check out this counting:
