  1. Know the Computer Multimedia tools

  2. Computer essentials

  3. Computer essentials • Hardware = physical component in the computer • Software = is the programs or systems that is operater within the hardware • Peopleware

  4. Hardware

  5. Hardware MOTHER BOARD Mother board is the heart of the computer. This component is the bigger part in the computer and every component attach into it someway. This is because all different component use motherboard to communicate and to work with each other.

  6. Hardware • CPU (Central Processing Unit) • Processes your instructions, performs calculation and manages the flow of information through the computer • Determine the speed by “clock speed” in MHz or GHz • CPU is the brain of the computer that put in to the Processor socket in motherboard

  7. Hardware • CPU (Central Processing Unit) • Intel (Pentium 4, Celeron, Pentium D, Xeon) • AMD 64, 64x2 • G4,G5 • Intel Core Duo, Core2Duo

  8. Hardware • Memory • RAM (Random Access Memory) • Volatile memory • Measure in megabytes (MB) or gigabytes (GB) There have many kind of RAM - SD RAM -DDR 1 -DDR 2 -DDR 3 ( The Latest one)

  9. Hardware • Memory • ROM (Read Only Memory) • Non Volatile memory • For save data • Hard disk • CD, DVD disk • Flash Drive • Memory card (MMC, SD, CF, XD, MS etc.)

  10. Hardware • Memory • Size of memory • 8 bits (b) = 1 Bytes (B) • 1024 B = 1 Kilobyte (KB) • 1024 KB = 1 Megabyte (MB) • 1024 MB = 1 Gigabyte (GB) • 1024 GB = 1 Terabyte (TB)

  11. Hardware • Connection • Port to connect with peripheral equipments • SCSI (Small Computer System Interface) • Transfer up to 320 MB/second • SATA (Serial ATA) • Transfer up to 150 MB/Second (SATA2 to 300MB/S) • USB (Universal Serial Bus) • USB 1.1 transfer up to 12 Mbps • USB 2 transfer up to 480 Mbps • FireWire (IEEE1394) • FireWire 400 (IEEE 1394a) up to 400 Mbps • FireWire 800 (IEEE 1394b) up to 800 Mbps

  13. Hardware • Graphic Card • Chipset inside the computer to connect with monitor to show the output. • Often on a special graphic card slot (AGP (Advanced Graphic Port), PCI, PCI Express) • Also have the CPU call GPU (Graphic Processor Unit) Translate graphic and text onto the monitor screen

  14. Hardware • Audio Interface (Sound Card) • Output the sound from computer • Digital to Analog converter for audio • Some can input the sound to computer (A/D Converter)

  15. Hardware • Output Devices • Monitor • CRT (Cathode Ray Tube) • Produced by electron beams sweeping across the inside of a vacuum sealed glass tube • Connect by VGA Port

  16. Hardware • Output Devices • Monitor • LCD (Liquid Crystal Display) • Each Pixel will produce a Red, Green or blue color on the screen • Lower resolution than CRT but for new technology are developed • Connect by DVI Port (Digital Visual Interface)

  17. Hardware • Output Devices • Monitor • Dot pitch is an indicator of the sharpness of the displayed image. It is measured in millimeters (mm), and a smaller number means a sharper image.

  18. Hardware • Output Devices • Printer • Dot Matrix • Creates characters by striking pins against an ink ribbon. Each pin makes a dot, and combinations of dots form characters and illustrations. • Inkjet Printer • Sprays ink at a sheet of paper. • produce high-quality text and graphics. • Laser Printer • Uses the same technology as copy machines. • produce very high quality text and graphics.

  19. Hardware • Input Devices • Keyboard • Mice • Graphic Tablets • Scanner • Film Scanner • Digital Camera

  20. Software • OS (Operating System) • Windows (2000,XP) • Macintosh (OS 9, OS X) • Linux
