How to choose a good keyboard?

Computer keyboards can be divided into mechanical and capacitive. Mechanical keyboard is an early keyboard, which is characterized by: striking the keyboard hard, making fingers tired or even injured easily after long-term use, poor hand feeling, loud noise, quick keyboard damage and high failure rate. Capacitive keyboard is characterized by less force, less keystroke, better feel and longer keyboard life. So it is wise to choose a capacitive keyboard.

2. Check the quality of the keyboard

The quality of computer keyboards produced by different manufacturers varies greatly, so when buying a keyboard, we should first check whether the exposed part of the keyboard has been finely processed and whether the surface is beautiful. Inferior computer keyboards not only have rough appearance, poor elasticity of keys, but also have poor internal printed circuit board technology.

3. Pay attention to the feel of the keyboard

Because there is a lot of contact between the keyboard and the hand, the feel of the keyboard is also very important. It is not good to feel too light or too soft, unless you are used to such a keyboard. If the hand feels too heavy and hard, the keys will be loud. A good keyboard key should be smooth, soft, moderately elastic and sensitive, and should bounce up immediately after the key is released, without shaking horizontally. A good mute keyboard should be almost silent when pressed and bounced. So when buying a keyboard, try to feel it. There were also many subjective factors at that time. The most important thing is to feel comfortable and quiet.

4. Pay attention to the comfort of using the keyboard

If possible, it is best to use the ergonomic keyboard invented by Microsoft. The keyboard is divided into two parts, and the two parts form a certain angle to adapt to the angle of the human hand, so that the input does not have to bend the wrist. There is also a wrist rest, which can hold the wrist up and prevent it from bending up and down. This kind of keyboard is mainly suitable for users who need a lot of keyboard input, and the price is high, which requires users to adopt correct fingering, and consumers should choose according to their own situation. Now many standard keyboards also add a wrist tray, which can also protect the wrist to some extent. These keyboards also often call themselves ergonomic keyboards. Pay attention to the difference.

5. Consider the layout of key positions.

The layout of PC keyboards and keys from different manufacturers is sometimes not exactly the same. At present, the standard keyboards mainly include 104 and 107, and 104 keyboard is also called Win95 keyboard. 107 keyboard, also known as Win98 keyboard, has more power management keys such as sleep, wake-up and start-up than 104 key. Now, for people who are used to win95 keyboard, it may be inconvenient to replace the original keys with three extra keys. So when buying, you must pay attention to the keyboard that suits your habits.

6. Interface type

AT present, there are three common keyboard interfaces in the market: old AT interface (commonly known as big mouth), PS/2 interface (commonly known as small mouth) and USB interface. The old AT interface has been gradually eliminated, but some keyboards with this interface are still on sale in the market, so friends should pay attention when purchasing. At present, the keyboard with PS/2 interface has the largest market share. If your motherboard is old and only has the old AT interface, you can buy a patch cord to use the PS/2 keyboard on the AT interface, but you will lose the function keys except 104. USB keyboard is a new product. The keyboard structure is basically the same as AT and PS/2 keyboards, but it is changed into USB interface. However, this keyboard needs the support of the motherboard to be used under BIOS and DOS, so it is not suitable for purchase at present.

Authenticity keyboard authentication

Generally speaking, the main difference between a real keyboard and a fake keyboard lies in the electronic components inside the keyboard. However, it is impossible for us to disassemble the keyboard for identification when we buy it, so observing the appearance of the keyboard has become the main identification method.

Because different keyboards are very different, although different keyboards have different recognition methods, there are many similarities. Keycaps (that is, those plastic keys) of a keyboard are the easiest way to tell the difference between a genuine keyboard and a fake keyboard. Generally speaking, the keycaps of genuine keyboards will be treated by some advanced technologies (such as laser etching technology), and the characters on the keycaps are delicate and slightly raised to the touch, which will not be worn and faded even after long-term use.

The key caps of fake keyboards are generally screen printed, and some of them are slightly "professional", which may be shot by a laser machine. This keycap has a rough font and is easy to be scraped off by hard objects. In addition, the colors of the keycap and keycap of the genuine keyboard and the keycap and the keyboard body are basically the same, while the counterfeit keyboard is likely to have color difference. In terms of workmanship, a genuine keyboard is very neat and the keys are very symmetrical and tidy.

I believe these can guide you to buy a keyboard.
