Hardware is an aspect of your computer which, unlike software, does not need to be changed frequently. Therefore, if you do not need to replace your equipment, make sure you buy equipment that lasts when you buy it.

Many people neglect the need and responsibility of computer hardware and focus instead on the software. Without proper hardware, your computer will not work properly.

The term hardware can be defined in many aspects of the computer, the most important aspect is your motherboard. The motherboard is classified as the heart of the computer. The main purpose is to provide electrical and logical connections. Without motherboard, the computer will not work. Components such as external storage, video and audio display are connected to the motherboard via connectors and cables.

The central processing unit (CPU) is also on the system board and acts as another important part of the computer. The CPU makes most of the calculations that a computer does. The processor and motherboard are in the computer tower because the computer's fan is necessary to maintain safe temperature and food on your computer, which of course is necessary for the computer to work properly. With all of these elements, you'll also find the sound card and graphics card on your computer in the computer's tower. Your video card, also called a display driver, is important to your computer because it allows you to get a good resolution without watching it, watching videos, playing games or watching flash images on websites. ,

One last major hardware stored in the computer's tower is the computer hard drive. The hard drive is the storage area of ​​your computer system. All your applications and applications, as well as pictures, music, video and all types of media on your computer are stored on your computer's hard drive.

All of the above-mentioned materials are stored in the computer tower, but some parts of the hardware are visible on your computer, such as removable media, such as CD players, DVD players, floppy disks and USB ports.

When it comes to purchasing these hardware, most people go directly to the biggest brand store and pay high prices for the devices, which will make you much cheaper in another way. If you want to buy computer equipment, you have several options instead of buying new products. For example, computer software sells all kinds of computer equipment at very reasonable prices. If you know what you are looking for, you can find many things at a computer fair. But if you prefer to buy from a dealer, have you been thinking about buying used equipment? He is not discouraged from the term used, which means that he would buy new material that the customer returned and the reseller reset. Dell is an excellent example of a company that often sells reset hardware that has been repaired to the new standards.

All units are new and only have minor problems, such as a small monk. Retailers like Dell sell refurbished devices in their store and do it on the Internet, for example on eBay. All of these units are sold at a reduced price, approximately 10% to 40%, discounted from the original price, depending on the interest rate. So, next time you have to buy computer equipment, buy instead of a high price.

So far, all the habits of the term laptop, and many were able to use one. What are the differences between a laptop and a netbook computer?

A netbook is a small computer that weighs as much as a book you would take on a transatlantic flight. Usually it is about 2 to 3 pounds. A netbook computer is primarily intended for access to the Internet. It does not have much computer power to perform most complex applications. However, it is useful for online access to your e-mails, Skype and your documents. Another important difference is that most netbooks do not have an optical drive (DVD or CD player).

A laptop can be as small as a 10-inch screen or as big as a 17-inch screen. These 10 inches correspond to the upper limit of netbooks, with some overlap. Laptops usually also have wireless network cards, a lot of processor power with good processors and large amounts of memory and storage. Most come with an optical drive and many with card reader to read from USB devices. Laptops can be as powerful as desktops and weigh about 5 pounds or more.

Both must be removed from their luggage at the security check at the airport.

Netbooks are also made to be cheap. This may mean lower quality components or other comfort issues. However, this places them in a price range which makes them much cheaper than laptops.

In summary, netbooks are not only smaller than laptops, they also have less processing power and no optical drive. If you want a real computer, get yourself a laptop. If you want a lighter version of a computer for important Internet access, a netbook may be right for you.

Beth Eshel is investigating the intensive purchase of a netbook computer. The laptop was too heavy to travel and she preferred desktop computers at work and at home. The netbook is your perceived response to the travel document.

 

When the computer is turned on, almost all items become hot. Continued exposure to high temperatures can cause serious damage to your computer.

Here's a list of ways to keep your computer in good condition.

Check if your fans are working.

This is the first step if it turns out that the computer is overheating. Open the bag and check that all the fans are still working. If at least one of them stops working, you can consider repairing or replacing it.

Regularly clean the computer.

It is important to clean your computer regularly, especially fans. The fans installed on the computer are used to actively cool the computer. Over time, dust and dirt can accumulate in these fans. Accumulated dirt can slow down or, in the worst case, prevent the fans from working. If the fans do not blow hot air quickly enough, some internal components may overheat.

How to clean the fan:

1. Turn off the computer.

2. Open the computer bag.

3. Remove the fan from the computer if there is too much dirt in the computer casing.

4. When cleaning the fan, you can use compressed air, a small electronic vacuum cleaner or a vacuum cleaner or a damp cloth.

5. If you are using a damp cloth, make sure that the fan is dry or free of moisture before reconnecting.

Also clean other parts of the computer, such as the monitor, mouse and keyboard.

Before cleaning any piece of hardware, make sure that the device is turned off. Otherwise, the computer is exposed to electrostatic discharge, which can damage parts and also tend to merge with the ground.

Before cleaning the equipment, refer to the manufacturer's instructions to check that you have received the recommended cleaning or care instructions.

Do not spray or flush the liquid directly on the part of the computer.

Do not limit the air flow around the computer.

Place the computer in a room where sufficient air can flow. Make sure it is not directly next to other objects that prevent air from circulating, such as walls or other computers. There must be at least two or three inches on both sides. Since most of the hot air comes out of the air outlet at the back of the computer bag, this section should be completely clean and open.

Move your computer to a cooler, cleaner environment.

Move your computer to a well-ventilated place. It is important that the physical mode does not add additional heat to the computer. Make sure your computer is not near a stove, refrigerator, appliances or other devices that can blow hot air or transfer heat to your computer.

To avoid overheating your computer, place it in an air-conditioned room.

Note Be careful when moving the computer to avoid damaging sensitive components such as processor, graphics card, hard drive, and motherboard.

Use your computer with the box closed.

It seems logical to leave the case open while the computer is running to keep it cooler. That's right But dust and dust accumulate and seal computer fans faster when the case is open. This can slow down the fans or prevent cooling of your computer.

Update the processor's fan.

The processor is the most important component of the computer. When you run demanding applications, the processor and graphics card generates more heat. It can be so hot that it can be boiled.

Consider purchasing a high quality processor fan of higher quality that can keep the CPU temperature lower than that of the computer's unintegrated processor fan.

Consider installing a specific fan for the component.

If you find that the other components are overheated, install a certain component fan to cool it.

Remember to install a box cover.

This small fan can be connected to the front or back of the computer. There are two types of fans: one can vent colder air inside the box and the other can blow hot air out of the box. Installing both is an excellent way to keep your computer fresh.

Turn off the computer when not in use.

A computer continues to produce heat while it is working, even when not in use. If you only have a few minutes of inactivity, put at least your computer to sleep. Basically, the computer also turns off, but the open files and programs are stored on your hard drive.

Also disconnect external devices that are no longer used, such as B. printer and scanner.

Overheating can destroy and shorten the quality of life on the computer components. The main advantage of keeping your computer fresh is that it can save you expensive repairs or unnecessary updates.
