Desktop Computer Parts and Components

Desktop Computer

The above picture is an example of a desktop computer and this computer was assembled locally but the components were imported from countries like China, Germany, Korea and others. This is the reason why we call it a clone desktop computer.

Nowadays, most of the branded computer such as Acer, Compact, Dell are made in Malaysia. We have so many factories which produce computer components.

From the picture above we can see the desktop computer normally consists of computer case (tower casing) with main components inside, a monitor, twin loud speakers, keyboard and mouse. A computer cases are usually constructed from steel and it is an enclosure that contains the main components of a computer. The main components of the computer are central processing unit, motherboard (mainboard / system board), memory cards (main memory), hard disk, graphic or video card, removable disk drives, power supply unit and cables wire to link among the components.

These components can usually be put together to build a computer. The motherboard is a main part of a computer that connects all devices together. The memory cards, graphics card, and microprocessor are mounted directly onto the motherboard (the processor in a socket and the memory and graphics cards in expansion slots). The backing storage is connected to it with cables and can be installed in the computer case or in a separate case. This is the same for the keyboard and mouse, except that they are external and connected to the input output (I/O) panel on the back of the computer. The monitor is also connected to the input output panel, either through an onboard port on the motherboard, or a port on the graphics card.

Several functions are implemented by chipsets or integrated circuit can be integrated onto the motherboard, typically Universal Serial Bus (USB) and network, ut also graphics and sound. Even if these are present, a separate card can be added if what is available isn't sufficient. The graphics and sound card can have a break out box to keep the analog parts away from the electromagnetic radiation inside the computer case. For really large ammounts of data, a tape drive can be used or (extra) hard disk can be put together in an external case.
