electricty can either be on or off....which when you get a cricut. Computer can understand on and off (electicty for example turning it on and off) how do u get computer to proccess more?

In a computer's number system there are only TWO numbers. Which are 0 and 1.

1- ON
0-OFF
In computer we go up by 2s insetad of 10s. For example:

10 decimal system: 1 10 100 1000 10000 100000
Binary (computers way):1 2 4 8 16 32 64-------->(binary code which comp uses)
EXAMPLES: 0 1 (EQUALS 2)
1 1 (EQUALS 3)
0 1 0 1 0 1 1(EQUALS 41)

How many diffrent pices of information can i do with 6 digits in binary number? whts the biggest number i can write? I have 63 diffent possablities

*everything that goes into the CPU is proccessed as binary*

digital system (10) based on our fingers

every single piece of information i sent to a computer...0 or 1 is a BIT.

Byte = is 8 bits

A thousand bytes (and 24) - kilobyte 1024 is a binary number comp only understand that so it cant be just a thousand since its not in the binary code.

how many bits in a kilo byte? - 8 thousand bites....8 thousand pieces of info
A megabyte is a million bytes
Gagabyte is a thousand gega byte
A thousand mega bytes is a gagabytes

floppy disk - 1.44mg - a million and a half bytes
USB Keys - 32 mega bytes
terabytes is - a thousand gega bytes
