Computer parts: a general guide
After reviewing my knowledge of the IT company, I discovered that we lack. Actually we are a large number of excavation inexperienced "technicians" to such an extent that I have decided to start writing an introductory article about computers and their components. In this article I which are the primary components of a standard desktop and / or tower computer. The article you are reading now includes an explanation of the key components designed an introduction to Computers offer. If you know (or think you know) what the parts already, you can not waste your time reading this article as it will probably pretty redundant and boring you. During the lecture I will explain what motherboards, processors, power supplies, memory, hard drives, solid state drives and expansion cards, as well as what they do.
The motherboard (also known as the motherboard or mobo) is the basic component that computers have to do anything. Without this component, the computer will not function properly. It would not once a computer because it would not know what a function is to begin. The motherboard comes in many forms, the most common of these mini-ITX, ATX, ATX and E-. The board houses several interfaces for many devices. Serial ATA (SATA) and ATA (commonly known as IDE) are the most common device interfaces. There are also several sets of pins on the board for the USB interface. These are clusters of pins are called headers and possible expansion. Also on the motherboard is a set of plastic slots (Generally located next to the CPU) to memory. The memory slots, there are different types expansion slots like PCI, PCI-E x1 and PCI-e x8 or x16. These expansion slots The user can later cards may provide various functions and for providing a foundation for the computer. None of these things without two other components, which first is the processor.
Central Processing Units (also known as processors or CPUs) are the brains of the whole operation. This component is the brain of the computer. To do something on your computer must have a properly installed CPU. When installing a CPU, make sure you are adjusting notches on the chip with the notches on the CPU socket. This will ensure that you do not damage the CPU or motherboard. The next step is to install the heatsink and fan to cool the processor. When installing these items should be cooled using thermal compound. Thermal compound is a paste containing the metal heat from the CPU to the metal of the heatsink. Without a heatsink thermal compound is useless. To install the heatsink, you need to manage a small amount of thermal paste (using a brush or spray) on the CPU. (It is very important that no thermal paste on the pin side of the CPU.) Upon application of thermal paste, you are adjusting the heatsink with the plastic on the motherboard and then press firmly. You are now ready to install the memory.
Random Access Memory (usually referred to as RAM or memory) is one of the basic components needed for a computer to function. When enabled without that, the computer gives a series of three evenly spaced beeps and will display nothing on the screen. Memory consists of multiple sets of integrated circuit chips set in a circuit board. The gold leads on the bottom of the Memory Stick conduct electrical signals to the circuitry and allow the computer to process information. The memory is volatile, which means that not all data when power to retain the system loss. For example, users often store their data in order to keep it in the event of a power failure. At installing the memory ensure that the notches with the bump (s) to fit into the card reader. Also make sure you get the right type of memory (DDR, DDR2, or DDR3).
Sometimes referred to as a PSU (Power Supply Unit), the power is a metal box with capacitors and other electrical components that allow the computer is powered by a simple socket. The power supply is responsible for drawing power from the mains and target specific components in the computer.
The hard disk drive (HDD) the part of the computer where the files are stored. Keep information on a magnetic disk platter, so the data can be used later. Volatile memory (not capable of storing data), but these are non-volatile disk. This is because instead of using a constant electric current, they use magnetic 1's and 0's Save the information. When choosing a hard disk, there are some options to consider. How much storage is needed? This is a question to consider due to the relatively large number data users are generally processed and stored in the course of their life (such as photos or music). Usually bigger is better, but users probably do not need a hard have a terabyte drive. How fast is the need to spin? Again, faster is better, but faster is also equal expensive. Higher rpm's means faster read / write speeds which the computer just that much faster. What about SSDs? SSDs (Solid State Drives) are a relatively new improvement in the data storage market. Taking into account their relatively young age, they are not necessarily the best method of storage for the average user. They are currently more focused on the enthusiast or gamer than the average PC user. They also have a higher cost per gigabyte than the average hard drive because of the faster read / write speeds.
Optical disks (like CD and DVD drives) are considered as a removable storage media devices. These devices use lasers for both reading and writing information on removable disks. The drives store information by sinks In their reflective coating. As the disc spins, the optical drive projects invisible laser light to the disc, and receives the stored information via the output deflected. Write or burn data to disk is performed in much the same way, except that the laser changes the way the pits on the disc are arranged.
Graphics cards are the most appropriate components of a computer. A graphics card has an onboard GPU (Graphics Processing Unit) and its own set of graphics memory. Modern graphics cards make frequent use of PCI Express interface slots to communicate with the motherboard. Often the high-end graphics cards require power directly from the diet. Other lower-end graphics cards can easily be powered by the PCIe bus. There are two primary producers of computer graphics cards: ATI and NVIDIA. These two companies have many nice cards and are constantly improve. Before choosing a graphics card the user must consider what the primary use of their computer will be. Gaming computers generally need a mid-range to high-end graphics card. Computers will be used for surfing the Internet and word processing may not need a graphics card expansion.
Sound Cards ensure better sound quality and additional channels. Onboard sound cards have a microphone, and audio speaker / headphone ports. Expansion slot sound cards have the Generally four ports for surround sound from right to left, rear stereo, subwoofer, and a MIDI / game port. The gates of the graphic cards are labeled as follows:
In short, there are many components needed for a computer to function. During the lecture, I explained what motherboards, processors, power supplies, memory, hard drives, Solid State Drives and expansion cards, as well as what they do. I hope this article is useful for you
