Blog Entry 4.1 - IFS H/W Infrastructure

     The image above is showing how information is translated into binary code so the computer can manipulate and store the information.  The image starts off with the computer showing the word "HELLO" on the monitor.  It then goes on to show how the computer changes this word into 8-bit binary code (American Standard Code For Information Interchange) or ASCII.  Once this is finished it is stored inside of the computers system unit and is stored inside of the registers.  The reason the computer cannot just read the word "HELLO" as H-E-L-L-O is because the computer can only understand on or off, therefore the computer must use its machine language of 1's and 0's in order to understand.  The process of inputting something in your computer starts with the person using an input technology (keyboard, mouse etc.) to key something into the computer.  Next, the computer will use processing technologies (ALU, Control Unit and Registers) in order to break down the information that has been given. The ALU or Arithmetic Logic Unit is used to do all of the Arithmetic aspects on the information.  The Control Unit is to schedule when things in the computer need to take place.  The Registers are used for internal memory inside the computer.  Lastly, the information is converted to output technology and is shown or heard on an output device (Monitor, Printer, Speaker).
