    • By: Tessa Barbee Per. 3 History and Flow
      • To find out how the computer works and what steps it takes to process information lets dive deep down inside it.
      Introduction
      • First we will start out by learning about input:
      • Input Is a system where you enter your information into the computer.
      • Types of input are your internet, keyboard and mouse.
      • - Input is the first step in the computer has to go through
      INPUT
      • The processor is one of the most complex stages:
      • This is where Fetch, Decode and Execute sort through the information
      • - Here the information is then sent to the place its has to go and does what it has to do.
      Processing
      • Now lets take a closer look at Fetch, Decode and Execute.
      • Fetch retrieves the data and passes it on to Decode.
      • Decode has no memory, and decodes binary
      • Execute has calculators and places in data in memory ( only reads ones and zeros.)
      Fetch, Decode and Execute
      • Memory is a very important part in storing the data.
      • it has a long term holder and short term holder
      • These holders storage containers are called RAM and ROM
      • Just like in your head a computer has a memory too
      Memory
      • We will take a closer look at RAM and ROM:
      • RAM is random access memory this is where data is stored temporarily
      • ROM is read only memory where information is usually stored for long periods of time
      RAM and ROM
      • Output is the last stage in the computer process.
      • information is now displayed
      • Output comes in forms of a printer, on the screen, speakers or some other way that it is shown to the user.
      Output
      • Lets go over what we learned:
      • The data is first put into INPUT
      • It is then sorted through in PROCESSING
      • After it is stored in MEMORY, RAM or ROM
      • Then it is shown to the user in OUTPUT
      Conclusion
      • What was going on in 1991 through 1993?!?
      Computer History
      • Well there was some major advances in computers:
      • -ID software is founded 1991
      • -Fifty World Wide Web servers are known to exist 1992
      • -FRISK software is founded 1993
      • Internet experiences world wide growth
      • The computer game Myst is released and later is honored for being one of the most popular
      Information
      • Since there was an internet growth lets take a closer look at the internet:
      • Easier ways to find things
      • You can talk to other
      • people
      • Faster ways to get
      • information
      Internet
    • I hope you enjoyed!! : ) (and learned a little something) THE END
