Functions on Computer Parts

Every part of the computer has a different task, such as a television that has a different task on each part, each part works 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 arise on the computer.

And below is a description of the functions on computer parts:

  • Processor / CPU, processor known as the brains of the computer. But in reality this statement is less precise. Processor count is simply a tool appropriate. Such as addition, subtraction, multiplication or division number. There are two parts in 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 Word, spreadsheets, and the Windows Desktop. The other half is called Floating Point Unit. The task of this unit address numbers are 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's processor has better performance than other processors, but AMD Athlon proseccor gradually has become a strict competitor to Intel. This is the brain in function on computer parts.
  • Hardisk is a metal device that typically exist in a computer. The main reason for having the device of a computer hard drive is because HDD is the only device that can store data when the computer is turned on.
  • RAM is a device that quite confusing compared to the hard drive, because both are data storage, but both are very different. RAM is a chip that can accommodate the data, so just hold it without saving the data. RAM has more speed than the hard drive, and that's what makes the RAM has a price more expensive than hard drives, and it was also the cause why the RAM is not used as primary data storage, RAM is used as a liaison between the Hard Drive and processor. If the processor needs data from the hard drive, the chipset will take the data from the hard drive and then save it into memory, and then the processor will be able to retrieve data quickly. If the computer runs out of RAM space, it will cause such thing as "Virtual RAM". Virtual RAM is just an extension of RAM that is on a hard drive. As noted previously, the Hard drive has a lower speed than the RAM, so when the computer gets the data from the hard disk, the computer would run so slow.
  • 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 to go through the RAM in the process of data transmission. And that is why the modern day computer can run very fast. Without cache, the processor will be many who have limitations in the data transmission process based on the speed of RAM, and worse the computer can run very slowly. The cache is divided into two parts level. The first level is L1 which has a size of 32 KB to 128 KB. It is split in the middle, in the CPU core, next integer and the Floating Point Unit, half of the store data, and save the other half used processor instructions to carry data. The second level cache, called L2, is used only for data. Some of the L2 cache are on the motherboard and some are located within the CPU. Cache Level 2 is currently in the CPU, along with the L1 cache.
  • The chipset is the most important part of the computer. It controls communication between components. The chipset is divided into two parts. The first chip is called the North Bridge, which handles communication between the AGP, RAM, processor, and the South Bridge of the chipset. And the second chip is the "South Bridge" that can manage all 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.

Thus the explanation of the functions on computer parts, hopefully this article can be useful for those who read it.
