What Is a Wireless Desktop Computer?

A desktop computer is an independent phase-separated computer that is completely unconnected with other components. Compared to laptops and netbooks, it is relatively large. The host, display, and other equipment are generally relatively independent. They generally need to be placed on a computer desk or a dedicated computer. On the workbench. Therefore named the desktop computer.

The host, display, and other equipment are generally relatively independent. They generally need to be placed on a computer desk or a dedicated computer. On the workbench. Therefore named the desktop computer.

The hardware system includes: chassis (power supply, hard disk, memory, motherboard, CPU-central processing unit, optical drive, sound card, network card, graphics card), monitor, keyboard, mouse, etc. (also can be equipped with headphones, speakers, printer, video screen, etc.) . Home computers generally have onboard sound cards and network cards. Some motherboards have integrated graphics. The English full name of CPU is "Central Processor Unit", which translates into "Central Processor Unit" in Chinese. Its role in the PC can be said to be equivalent to the role of the brain in the human body. All computer programs are run by it.

The motherboard is also called Mother Board. It is actually a circuit board with a variety of circuits on it. It can be said that it is the nervous system of the PC. The CPU, memory, graphics card, sound card, etc. are directly installed on the motherboard, and the hard disk, floppy drive and other components also need to be connected to the motherboard through wiring.

Generally, the computer parts placed in the case are collectively referred to as "hosts". It is the most important part of the computer. The main components such as the motherboard, CPU and hard disk are all in the host.

First, turn on the machine regularly, especially in the wet season, otherwise the case will be short-circuited due to the moisture in the case, and the computer that is often used is not easy to break. But if there is no lightning rod around the home, do not turn on the computer during thunder and unplug all plugs.

Second, pay attention to heat dissipation in summer, avoid using the computer for a long time in the room without air conditioning, pay attention to antifreeze in winter, the computer is actually afraid of cold.

3. When not in use, cover the display, case, and keyboard with a cloth that is breathable and coverable, which can prevent dust from entering the computer.

Fourth, try not to switch on and off frequently. When not in use, simply use the screen saver or hibernate. When the computer is in use, do not move the chassis, do not subject the computer to vibration, and do not plug in and plug all hardware devices with power on, except of course using USB devices.

5. Use a power socket with overload protection and three pins, which can effectively reduce static electricity. If you can feel static electricity in your hands, use an enameled wire (that is, plastic outside and copper wire inside) with one end wrapped around the rear panel of the chassis. It can be wrapped around the fan's air outlet. The other end should be wrapped around the water pipe. If you can't touch the water pipe, find it nearby, as long as the metal object can contact the ground (soil).

6. Develop good operating habits and minimize the number of times you install and uninstall software. Seven, follow the strict sequence of power on and off, you should first turn on peripherals, such as monitors, speakers, printers, scanners, etc., and then power on the chassis. Otherwise, turn off the power of the chassis first. (At present, most computer systems can automatically turn off the power of the case)

8. Do not place speakers around the display, there will be magnetic interference. The darker the monitor during use, the better, but it is better for eye comfort.

Nine, every six months, carry out a general cleaning of the computer to completely remove the internal dirt and dust, especially the chassis, but it must be carried out under the premise of confidence, if you are not familiar with the hardware, it is better to touch less.

X. Develop a habit of combining work and rest. Do not play the computer overnight. It is not conducive to the life of the computer, and it is more harmful to the body. The monitor, the chassis, the mouse, and the keyboard are radiated. The amount is actually larger.
