FUNCTION ON COMPUTER
PART OF THE FUNCTION ON COMPUTER
Every part of the computer has a different task, such as a car that has a different task on each part, each part works to do each task. By knowing the duty of every part of the computer, we will be much easier to find and resolve problems that arise on the computer.
And 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 number. There are two parts of a processor that perform calculations. The first part is called integer units, the task of the integer unit is to overcome the simple numbers, such as -5, 13, ½ and others and its main task is used for business applications, such as applications Word, Spreadsheet and Windows Desktop. And the other processors called Floating Point Unit. The task of this unit to overcome the numbers quite difficult, as root, pi, “e.” and logarithms. This section is usually used in the process of making 3D games, to calculate the position of pixels, and images.
In recent years, Intel processors have better performance than other processors, but gradually proseccor AMD Athlon has become a strict competitor to Intel.
Hard disk is typically a metal device inside a computer. The main reason of having a computer is because perangkan Notebook Notebook is the only device that can store data on computers when not in running condition (of course, besides some other external storage devices).
Random Access Memory
RAM is a bit confusing devices compared with Hardisk, as both a place penyimpnan data, but both are very different. RAM is a chip that can accommodate the data, so just hold it without storing the data. RAM has more speed than the Notebook, and that’s what makes RAM has higher prices than the Notebook, 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 Notebook, the chipset will take data from the Notebook and then save it to RAM or the memory, and then the processor will be able to retrieve data quickly.
If the computer running out of RAM space, it will cause the name “Virtual RAM”. Virtual RAM is the name for the extension of the existing RAM on a hard drive. As previously explained that the Notebook has a lower speed than RAM, so if the computers get data directly from the hard disk, then the computer will run so slowly.
Cache / “L1, and L2″
A cache is a high-speed RAM. Cache store general data and instructions from the processor so that the cache does not need the RAM in the process of data transmission. And that’s why the modem on your computer today can run very fast. Without cache, the processor will have many limitations in the data transmission process based on the speed of RAM, and worse the computer can run very slowly. Cache is divided into two parts levels. The first level is L1 which has size of 32 KB to 128 KB. Cache is divided in the middle, in the CPU Core, in addition to integer and at the Floating Point Unit, half of the store data, and the other half of the store processor instructions used to carry data. Chache second level search is called L2, is used only for the data. Some of the L2 cache in the motherboard and some are located in the CPU section. Level 2 cache is currently in the CPU, along with Level 1 cache.
The Chipset
Chipset is the most important part of the computer. Chipset can manage the communication between components. Chipset is divided into two parts. The first chip is called “Nort Bridge” that can regulate 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 Inputan and output on the computer, including the PCI and ISA bus. Processor, Memory (RAM), cache, and chipset work together to activate the computer functions.
