Function from Computer Part

Every part of the computer have different tasks, like like a car that has a different task on every part, every part of the work to perform their respective duties. By knowing the duty of every part of the computer, we will be more easy to identify and resolve problems that appear on the computer.
And this examine below is an explanation of the duty of every major component of the computer.

Processor

"CPU"
Processor known as the brains of the computer. But in fact the statement was less precise. Processor is an appropriate computational tools. Such as addition, subtraction, multiplication or division numbers. There are two parts of a processor that perform calculations. The first part is called integer unit, integer unit is the task of overcoming a simple number, such as -5, 13, ½ and others and its main task is used for business applications, such as applications of Word, Spreadsheet and Windows Desktop. And the other processor is called Floating Point Unit. This unit is the task of overcoming the numbers is quite difficult, as root, pi, "e." and logarithms. This section is usually used in the process of making 3D games, calculate the position of pixels, and images.
In recent years, Intel processors have better performance than other processors, but AMD Athlon processor gradually has become a strict competitor to Intel.

HD

Hardisk is a metal device that normally exist in a computer. The main reason of a computer has device Hardisk is because hard disk is the only device that can store data when the computer is not in a state of light (certainly in addition to some other external storage devices).
Random Access Memory

RAM
RAM is a device that quite confusing compared to the hard disk, because both are places store of data, but both are very different. RAM is a chip that can accommodate the data, so just hold it without saving the data. RAM has a speed more than the hard disk, and that's what makes the RAM has a price more expensive than the hard disk, and it was also the cause why the RAM is not used as the primary fund storage, RAM is used as a liaison between the Hard Drive and processor. If the processor needs data from the hard disk, then the chipset will take the data from the hard disk and then store it in RAM or the memory, and then the processor will be able to retrieve that data quickly.

If the computer runs out of RAM space, it will cause the name "Virtual RAM". Virtual RAM is the designation for the extension of existing RAM on a hard drive. As previously explained that the hard disk has a lower speed than the RAM, so if the computer get data directly from disk, the computer will be running so slow.

Cache
"L1, and L2"
A cache is a high-speed RAM. The cache stores data and instructions from the processor in general so the cache does not need to go through the RAM in the process of data transmission. And that's the reason why the modem on today's computers can run very fast. Without cache, the processor will be many who have limitations in the process of data transmission based on the speed of RAM, and worse the computer can run very slowly. Cache is divided into two parts level. The first level is L1 which has a size of 32 KB to 128 KB. The cache is divided in the middle, in the CPU Core, in addition to integers and on the Floating Point Unit, half of the store data, and the other half storing processor instructions are used to carry data. Cache second level search is called L2, is used only for data. Some of the L2 cache inside the motherboard and some that are within the CPU. Level 2 cache currently resides in the CPU, along with Level 1 cache.

The Chipset
The chipset is the most important part of the computer. The chipset can manage the communication between components. The chipset is divided into two parts. The first chip is called "Nort Bridge" that can manage the communication between the AGP, RAM, Processor, and "South Bridge" on the chipset. And the second chip is the "South Bridge" that can manage all the input and output on the computer, including the PCI and ISA bus. Processor, Memory (RAM), cache, and chipset work together to activate the computer functions
