HARDWARE

A personal computer is made up of multiple physical components of computer hardware, upon which can be installed an operating system and a multitude of software applications to perform the operator's desired functions.
Though a PC comes in many different forms, a typical personal computer consists of a case or chassis in a tower shape (desktop), containing components such as a motherboard.

Motherboard
Main article: Motherboard
The motherboard is the main component inside the case. It is a large rectangular board with integrated circuitry that connects the rest of the parts of the computer including the CPU, the RAM, the disk drives (CD, DVD, hard disk, or any others) as well as any peripherals connected via the ports or the expansion slots.
Components directly attached to the motherboard include:
  * The central processing unit (CPU) performs most of the calculations which enable a computer to function, and is sometimes referred to as the "brain" of the computer. It is usually cooled by a heat sink and fan.
  * The chip set mediates communication between the CPU and the other components of the system, including main memory.
  * RAM (Random Access Memory) stores all running processes (applications) and the current running OS.
  * The BIOS includes boot firmware and power management. The Basic Input Output System tasks are handled by operating system drivers.
  * Internal Buses connect the CPU to various internal components and to expansion cards for graphics and sound.
      * Current
        * The north bridge memory controller, for RAM and PCI Express...
