Intro to Bits, Bytes, and Storage

Bits, Bytes, and Storage

How can we relate to the terms Bits and Bytes?
“This computer has a 64-bit processor with 4 Gigabytes of RAM and 200 Gigabytes of hard disk space”
“My parents played Atari (8-bit) and I play Nintendo (64-bit)”

Key Terms
Bits
Bytes
Binary numbers
All of the prefixes related to storage
KB
MB
GB
TB

Bit
bit = From a shortening of the words “binary digit”
the basic unit of information for computers
1 or 0 are the only values

Byte
Byte = 8 bits
Each keyboard character is stored as a Byte
Example  A = 01000001

This is an excellent diagram

How does a computer processor understand bytes????
The processor is made of zillions of Transistors.
Transistor on = 1
Transistor off = 0

9
A transistor is a switch.
Switch on = 1
Switch off = 0
The ”A” exists as a pattern in eight transistors, where some are “turned on” (charged) and others are not.
Together these 8 transistors make up one byte.

Give this a shot…..
The Binary Math Game

UNITS  Big & Way Big Bytes
Byte a grouping of eight bits for instance --> 0110 0001
Kb (kilobyte) about 1000 bytes
Mb (megabyte) about one thousand Kb or one million bytes
Gb (gigabyte) about one thousand Mb or one billion bytes
Tb (terabyte) is about one thousand Gb or one trillion bytes

Terms for Storage Capacities
1 bit = 0 or 1 (b)
8 bits = 1 byte (B)
1 thousand bytes = kilobyte (KB)
1 million bytes = megabyte (MB)
1 billion bytes = gigabyte (GB)
1 trillion = terabyte (TB)

A file with size = 201 Bytes

MB of data
GB of data

Terabytes = a trillion bytes
