Computer components. The monitor or the monitor is a display device, the most important part in contact with the user directly, because we can see that information displayed through our monitor. Computer monitor, there are two widescreen CRT and LCD monitor which monitor 2 have different characteristics in terms of format, it is a CRT screen (CRT) monitors are most commonly used for desktop computer. There is a big tv. As before, have become extremely popular, but when the LCD monitor (LCD). CRT monitors have less and less until now we rarely see this kind of LCD computer shops sell. LCD monitor parts so that is used with desktop computers, and on the model of the notebook. Because it is monitor that has the size, shape, some make it easy to carry around. But the LCD monitor, this rate more expensive monitors CRT. Case (case) is the box or structure for storage of various computer equipment inside of it, which is the size of the case, it will be different, but the use or appropriate usage of each of the people, including those with the equipment locations that have much outdoor space. And in case it is there on the part of the power supply. Power supply (Power Supply) is a device that serves to deliver computer equipment parts, which if there are devices, such as hard disks of a bunch bunch CD-ROM drive, DVD drive, it should choose a high wattage power supply that has to be able to provide power, have adequate computer equipment. คีย์บอร์ดหรือแป้นพิมพ์ (Keyboard) เป็นอุปกรณ์พื้นฐานที่คอมพิวเตอร์ทุกเครื่องจะต้องมี เนื่องจากตัวคีย์บอร์ดใช้สำหรับการพิมพ์หรือป้อมข้อมูลต่างลงไปในเครื่องคอมพิวเตอร์ ในตัวคีย์บอร์ดจะมีทั้งที่เป็นตัวอักษรที่เป็นภาษาหลักของแต่ละประเทศรวมทั้งภาษาหลักอย่างภาษาอังกฤษอยู่ด้วย และยังมีข้อมูลทั้งตัวเลขและฟังก์ชันต่างๆ ที่จำเป็นสำหรับการใช้งานและอื่นๆ อีก เพื่อใช้สำหรับลงข้อมูลในตัวเครื่องของเรา โดยส่วนใหญ่แล้วคีย์บอร์ดมีลักษณะที่เป็นสี่เหลี่ยมผืนผ้าหรือมีลักษณะที่ใกล้เคียงกัน แต่ในปัจจุบันก็อาจมีลักษณะที่แตกต่างกันออกไป แล้วแต่ความคิดสร้างสรรค์ของคนออกแบบนั้นเอง Hard disk drive (Harddisk) is a device used for recording data, or the data store of a computer and a device that came with the computer, the hard disk will have a rectangular and have a circuit for controlling the work below, and a slot for the power cord and signal cable, various. By the internal components are closed to prevent the harm to occur. The motherboard (Main board) is a large sheet of PCB that combines critical electronic components together, which is the part that controls the behavior of devices within the whole PC. CPU (CPU) processor or processor or chip is called device are very important because they are responsible for processing from the input into. Video card (Display Card), the basic principle of the video card. When the programs send CPU processors when CPU processing is finished, it will send the information that will be displayed on the monitor video card video card then it will send the data to the monitor, based on the data obtained. Newer video cards that come out will have most of the circuit. To speed up a three-dimensional image display and memory to enough.By some versions of cards can be processed in the card, which will burden the CPU processing. Thus, the operation of the computer. Where the video card memory is on its own. If the card has a lot of memory. It will receive information from the CPU, which allows to display on a monitor with higher speed. Mouse (Mouse) is a device that feels good, easy to use with your mouse, move the pointer to different positions on the screen, or simply that the perilous position pointer. While the eyes on the monitor, you can use a tool to drag the mouse back and forth. The distance and the direction is relative, and it's the same as you move the mouse.The mouse can be divided into two types, mechanical, and optical. A mechanical model using the roller with weight and friction fit. When I move the mouse in any direction will cause the roller moves back and forth in that direction, but in the current roller mouse is rarely used. RAM (RAM).As the system's memory. Responsible for information sent to a processor CPU main memory of a computer system, which will collect data when a power supply only. If flashing or extinguished by the electrical The information is saved in the memory will be lost immediately. CD/DVD Drive Drive Drive Drive DVD-RW/CD-RW/is a drive for reading data from a CD ROM or DVD-ROM drive if you are if you want to save the data onto the disc will need to use a drive that can burn.When the CD-ROM drive, start the motor will start to rotate at a speed. Multiple values for a speed reading data from a CD-ROM. consistent in every sector. Whether it's the sector outside or inner circle, however, the laser light is then projected onto a CD ROM by the beam will be in focus with the lens moving position. By operation of the coil. A laser beam passes through to the CD-ROM and then is reflected. CD-ROM/DVD-ROM inside the CD-ROM or DVD-ROM drive is divided into track and sector similar to the disc, but the sector in the CD-ROM or DVD-ROM drive will have the same size. Every sector makes it possible to store more information.
