3. power supply work?
• A power supply is used to reduce the mains electric at 220 volts AC down
to some thing more useable, say 12 volts DC.Power supply sends electric
for HARD,DVD ROM & motherboard.

4. Motherboard Work?
• A motherboard it receives the electric from power supply and sends it to
other components ,RAM & CPUs place,other ports whith lots of other
things ,and it’s the most importan component.

5. Cpu work?
• The computer does its primary work in a part of the machine we cannot
see, a control center that converts data input to information output.
This control center, called the central processing unit (CPU), is a highly
complex, extensive set of electronic circuitry that executes stored
program instructions.

6. cpu fan work?
• CPU fan is the fan installed on CPU, which is used to cool
the CPU preventing it from heating or causingCPU damage.

7. Ram work?
• The chips that make up a computer's internal memorycome in two
broad flavors known as RAM (random accessmemory) and ROM
(read-only memory). RAM chips remember things only while a
computer is powered on, so they're used for storing whatever a
computer is workingon in the very short term.

8. video card work?{VGA}
• Graphic Card its another motherboard it contains GPU &VRAM,port,chipset…and
its used for speeding up our motherboard.

9. Gpu andVram ?
VRAM (video RAM) is a reference to any type
of random access memory (RAM) used to
store image data for a computer display. All
types ofVRAM are special arrangements of
dynamic RAM (DRAM).

10. Chipset work?
• The chipset is the "glue" that connects the microprocessor to the rest of
the motherboard and therefore to the rest of the computer. On a PC, it
consists of two basic parts -- the northbridge and the southbridge. All of
the various components of the computer communicate with the CPU
through the chipset.

11. hard drive work?
• A small hard drive typically has only one platter, but each side of it has a
magnetic coating. Bigger drives have a series of platters stacked on a
central spindle, with a small gap in between them.

Case is used for keeping components ,it gives computer a beautiful
Design and keeps us from some problems.
