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:
