2. HOW DO PEOPLE USE THE TERMS BITS AND BYTES? Some people might say: “This computer has a 64- bit processor with 4 Gigabytes of RAM and 200 Gigabytes of hard disk space.”

3. HOW DO PEOPLE USE THE TERMS BITS AND BYTES? Some people might say: “My parents played Atari (8- bit ) and I play Nintendo (64- bit ).” http://commons.wikimedia.org/wiki/File:Atari-2600-Wood-4Sw-Set.jpg http://commons.wikimedia.org/wiki/File:Nintendo_64.jpg

4. KEY TERMS & PREFIXES RELATED TO STORAGE Some key terms to remember are: Bits Bytes Here are some common prefixes related to storage: KB MB GB TB

5. BIT The term “bit” comes from shortening the words “binary digit.” A bit is the basic unit of information for computers. Binary means two. 1 or 0 are the only values

6. BYTE 1 Byte=8 bits Each keyboard character is stored as a Byte. For example: A=01000001

11. UNITS (FROM SMALLEST TO LARGEST) Byte- A group of eight bits. Kb (kilobyte)- about 1000 bytes Mb (megabyte)- about one million bytes Gb (gigabyte)- about one billion bytes Tb (terabyte)- about one trillion bytes Petabyte- 1 000 000 000 000 000 bytes Exabyte- 1 000 000 000 000 000 000 bytes Zettabyte- 1 000 000 000 000 000 000 000 bytes Yottabyte- 1 000 000 000 000 000 000 000 000 bytes (named after Yoda) Others include………..
