= What is a CPU? =

Definition
The central processing unit (CPU) is the unit which performs most of the processing inside a computer. To control instructions and data flow to and from other parts of the computer, the CPU relies heavily on a chipset, which is a group of microchips located on the motherboard.

The CPU has two components:


 * Control Unit: extracts instructions from memory and decodes and executes them
 * Arithmetic Logic Unit (ALU): handles arithmetic and logical operations

To function properly, the CPU relies on the system clock, memory, secondary storage, and data and address buses.

This term is also known as a central processor, microprocessor or chip.

What a CPU Looks Like and Where It's Located
A modern CPU is usually small and square, with many short, rounded, metallic connectors on its underside. Some older CPUs have pins instead of metallic connectors.

The CPU attaches directly to a CPU "socket" (or sometimes a "slot") on the motherboard. The CPU is inserted into the socket pin-side-down, and a small lever helps to secure the processor.

After running even a short while, modern CPUs can get very hot. To help dissipate this heat, it's almost always necessary to attach a heat sink and a fan directly on top of the CPU. Typically, these come bundled with a CPU purchase.

Other more advanced cooling options are also available, including water cooling kits and phase change units.

As mentioned above, not all CPUs have pins on their bottom sides, but in the ones that do, the pins are easily bent. Take great care when handling, especially when installing onto the motherboard.

CPU-Z:
CPU-Z is a freeware that gathers information on some of the main devices of your system :


 * Processor name and number, codename, process, package, cache levels.
 * Mainboard and chipset.
 * Memory type, size, timings, and module specifications (SPD).
 * Real time measurement of each core's internal frequency, memory frequency.
