task-2 Assembling And Dissembling of a Computer

Assembling And Dissembling of a Computer

AIM: To assemble  and Dissemble  the  hardware components  of  a personal computer.

Assembling: Grouping / Gathering  the all parts into the C.P.U is known as assembling

Dissembling: Removing / Disconnecting the all parts from the C.P.U is known as disassembling

Ports: a port represents a communication channel or endpoint. a port (noun) is generally a specific place for being physically connected to some other device,

1. VGA  Port(Video Graphic Adapter) for Monitor. No. of pins=15

      2.    Printer Port (or) Scanner Port for Printer (or) Scanner. No. of pins=25

3. PS/2 à Personal System for Mouse(Green) and Keyboard(Purple)
4. Com Port(Communication Port) for Serial mouse configuration. No. of pins=9
5. Audio Ports: Line In(Recording), Line Out (Speakers) MIC(Micro Phone)

6. Game Port: No. of pins=15
7. USB Port(Universal Serial Bus) for pen drives

Connectors: A "connector" transmits electrical power and/or electronic signals between two devices. A connector is best known for providing a physical link between two components.

1. IDE(Integrated Drive Electronic) for HD (or) CD-ROM
2. FDC(Floppy Drive Connector) for only floppy
3. SATA Connector  for SATA HD (or) SATA Drive
4. Front Panel Connectors  for Reset and Power Buttons

Chip sets: A chipset, PC chipset, or chip set refers to a group of integrated circuits, or chips,

1. North Bridge(Near to Processor): It Control the high speed devices like Processor, RAM, AGP Slot and PCI Express(Peripheral Component Interconnect Express).
2. South Bridge(Near to PCI Slots): It controls PCI Slots Connectors  and all Input and Output devices.

SMPS(Switched Mode Power Supply)

1. AT(Advanced Technology) : 12 pins
2. ATX(Advanced Technology Extended) : 20 pins
3. BTX(Balance Technology Extended) : 20+4 pins
4. MBTX(Micro Balance Technology Extended) : 24+4 pins

Power Connectors

1. MOLEX : for HD (or) CD and DVD-ROMs, 4-pins/4-wires.
2. MINI MOLEX: for only floppy, 4-pins/4-wires.

3. Super MINI MOLEX for extra power supply to the Mother Board, 4-pins/4-wires. 

      4.   Sub MINI MOLEX : to the CPU fan from the Mother Board, 3-pins/3-wires (or) 4-pins/4-wires.

Steps for assembling the system:

1. Take the case/cabinet and fit the SMPS with the help of the screw drivers.

2. And then place the mother board in the cabinet and fit screws carefully.

3. Connect the hard disk and CD-ROM into the cabinet with help of screw drivers.

4. Connect the power connections to all parts of the computer like motherboard, hard  disk and CD_ROM

5. Insert the IDE cables from mother board to hard disk and CD-ROM

6. Insert the RAM into RAM slots. First we have to check whether RAM is SDR (or) DDR.

7. Insert the expansion cards like NIC, network cards, etc...into the PCI slots.

8. Connections of all front panel connectors like power, reset, HDD etc.,

9. Finally check out the connections once and close the cabinet door. at last connect all the power connectors.        

Steps for disassembling the system:

1. First we have to remove the power connections.

2. Check out the power connections once and open the cabinet/case door.

3. Then disassemble the expansion cards like graphic cards, network cards, etc… into  the PCI slots.

4. Remove the RAM and Check the grounding in the plug to make sure that earthing is done properly.

5. Then disconnect the power connections to all parts of computer like mother board, hard disk and CD-ROM

6. Remove the hard disk and CD-ROM into the cabinet with the help of screw driver  Carefully.

7. Remove SMPS with the help of screw drivers.

8. Finally remove microprocessor and heat sink from mother board.

9. At last we have to remove the mother board from the cabinet
