    • FUNDAMENTAL ELEMENTS OF A COMPUTER
    •  
    • Output Device System Unit Input Devices
    • SYSTEM UNIT
      • THE CORE OF A COMPUTER IS RESPONSIBLE FOR PROCESSING AND STORING DATA AND CONTROLS ALL COMPUTER FUNCTIONS.
    •  
    •  
    •  
    •  
    • THE SYSTEM CASE
      • IS A PLASTIC AND METAL BOX THAT HOUSES COMPONENTS SUCH AS MOTHERBOARD, DISK DRIVES AND POWER SUPPLY UNIT
    • SYSTEM CASE TYPE
      • DESKTOP CASE-is designed to sit horizontally on a surface so that it is wider than it is long.
    • TOWER CASE
      • IS DESIGNED TO SIT VERTICALLY ON A SURFACE SO THAT IT IS HIGHER THAN IT IS WIDE.
    • PARTS OF THE CASE
    • MOTHERBOARD
      • IS THE MOST IMPORTANT COMPONENT OF YOUR COMPUTER, ONE POINT OR ANOTHER, EVERY OTHER COMPONENT CONNECTS TO THE MOTHERBOARD
    •  
    •  
    • THE CPU
      • The C entral P rocessing U nit- is the device that interprets and executes instructions. The CPU is the chip that functions as the “brain of a computer.
    •  
    • MEMORY
    • MAIN MEMORY
      • VERY CLOSELY CONNECTED TO THE PROCESSOR.
      • THE CONTENTS ARE QUICKLY AND EASILY CHANGED.
      • HOLDS THE PROGRAMS AND DATA THAT PROCESSOR IS ACTIVELY WORKING WITH.
      • INTERACTS WITH THE PROCESSOR MILLIONS OF TIMES PER SECOND.
    • RAM (Random Access Memory
      • Means the memory cells can be accessed in any order.
      • Its just a normal memory which means the computer can store, retrieve, alter or delete any items. It can be read and write. (volatile)
    • DIMM (Dual Inline Memory Module)
      • A computer RAM or main memory is build from a small circuit board or memory chip called MEMORY MODULES.
      • DIMM chips usually 64MB, 128MB or 256 MB, have to access pathways (read and write at the same time)
    •  
    • ROM BIOS Read Only Memory Basic Input Output System
      • Provides the industry standard program code that operates the fundamental components of the PC.
      • Ensures that the design of each manufacturer’s motherboard is PC-compatible.
    • CMOS RAM Complimentary Metal-Oxide Semiconductor
      • Stores the configuration of the PC (password, disk types, amount of memory installed, current time and date.)
      • Require very little power to operate and use battery power to maintain their settings.
    • SECONDARY MEMORY
      • IS WHERE PROGRAMS AND DATA ARE KEPT ON A LONG TERM BASIS.
      • COMMON SECONDARY STORAGE DEVICES ARE THE FLOPPY DISK, HARD DISK, AND COMPACT DISK, FLASH DISK.
    • FLOPPY DISK (DISKETTE)
      • IS A ROUND BUT COMES PERMANENTLY SEALED IN A SQUARE DUST JACKET.
      • THE TYPICAL 3 ½ FLOPPY DISK CAN HOLDS 1.44 MB.
    •  
    • HARD DISK
      • MIGHT HAVE A CAPACITY OF 40 GB.
      • IS NON REMOVABLE , ITS STUCK PERMANENTLY INSIDE THE SYSTEM UNIT
      • ITS ALSO CALLED AS “FIX DISK”
    •  
    •  
    • COMPACT DISK –CD
      • A CD THAT HOLDS MUSIC IS CALLED “Music CD or “Audio CD)
      • A CD THAT HOLDS computer data is called as “data CD”
      • It is also called as CD ROM.
    • CD-RW (CD-ReWritable)
      • A blank CD which you can write onto blank and then edit what you wrote.
      DVD (Digital Versatile Disk)
      • Can hold more information, a two hour movie or 4.7GB of data
    • OTHER PERIPHERAL DEVICES
    • VIDEO CARD
      • A board that plugs into PC to give display capabilities
      • It also called as video adapter, video board, video display board or graphics card.
    •  
    • INTERNAL MODEM
      • IN ORDER TO CONNECT TO THE INTERNET YOU NEED SOME FORM OF MODEM (Modulator/Demodulator)
      • Modem convert (modulate) the digital code to analogue code, then convert them back (demodulate) at the other end.
    •  
    • POWER SUPPLY
      • SUPPLIES THE FUEL (POWER) FOR THE COMPUTER. CONVERT THE VOLTAGE NEEDED TO THE MOTHER BOARD AND DRIVES.
      • IT ALSO CONTAINS A FAN HELPS IN COOLING THE COMPUTER
    •  
    • IDE AND FLOPPY RIBBON CABLE
      • IDE stands for Integrated Device Electronics.
      • This device contains wires that are used to transfer data between the motherboard and the drive/s.
    • End of the Lesson
