  • 2. Part IIntroduction
  • 3. Parts of Computer► Motherboard► CPU► Memory► Video Card► Power Supply► Hard Disk► CD/DVD Rom Drive► IDE Cable
  • 4. Motherboard- A motherboard is the central or primary circuit board making up a complex electronic system, such as a modern computer. It is also known as a main board, baseboard, system board
  • 5. Motherboard Design
  • 6. Microprocessor►Amicroprocessor -- also known as aCPU or central processing unit -- is acomplete computation engine that isfabricated on a single chip.
  • 7. Microprocessor Design
  • 8. Memory►Memory- is technically any form of electronic storage, it is used most often to identify fast, temporary forms of storage
  • 9. Video Card►A video card, (also referred to as a graphics accelerator card, display adapter, graphics card, and numerous other terms), is an item of personal computer hardware whose function is to generate and output images to a display.

  • 51. PC Maintenance• you use your computer more than a few hours per day, we suggest you not to turn off your computer at the end of the day. Instead turn off only the monitor to save electricity. Daily power up and down makes the components exposed to high and low temperature cycles that are not good for the life-time of the components, particularly the critical ones such as hard drives, CPU, and memory. The temperature cycle would result in expansion- shrinking cycle for the components. The life-time of electronic components would be increased if they are run at constant temperature with adequate ventilation.
  • 52. PC Maintenance• If your area experiences a few times of power outage per year, it is necessary to use a UPS. Sudden power downs while the system is running may cause severe damage to hard drives.• A tape backup and a lock to make systems hard to move are worthy investment for critical data.
  • 53. PC Maintenance• Use your hand to touch and feel the cover of your computer at least once a week. The cover should be at room temperature. If it feels warm there may be a problem! Check to make sure that the cooling fans on the power supply and CPU are working properly. Clean the air pathway on the back of the power supply on a regular basis.
  • 54. PART VI►Computer Networking
  • 55. TOOLS IN NETWORKING► RJ-45► Twisted pair cable► Crimp tool► Ethernet hub► router► Network Adapter Card (NIC)
  • 56. RJ 45► Eight-conductor data cable contains 4 pairs of wires. Each pair consists of a solid (or predominantly) colored wire and a white wire with a stripe of the same color.
  • 57. Twisted Pair Cable► Twisted pair cabling is a form of wiring in which two conductors are wound together for the purposes of canceling out electromagnetic interference (EMI) from external sources, electromagnetic radiation from the UTP cable, and crosstalk between neighboring pairs.
  • 58. Crimp Tool► crimpsRJ45 modular plugs. Simply place the plug with the cable in the crimp tool and squeeze the grips together, thus causing the plug to bite into the cable.
  • 59. Ethernet Hub► An Ethernet hub or concentrator is a device for connecting multiple twisted pair or fiber optic Ethernet devices together, making them act as a single segment.
  • 60. Router►A router is a device that determines the proper path for data to travel between different networks, and forwards data packets to the next device along this path.They connect networks together; a LAN to a WAN for example, to access the Internet.
