First of all, the wear resistance of the keyboard is very important, which is also a parameter to distinguish the quality of the keyboard. For some non-brand keyboards, the characters on the keys are directly printed, so that the characters on the keys will be worn out after a long time. And the advanced keyboard is engraved with laser, so the wear resistance is greatly enhanced. There is a common keyboard can be divided into two types of mechanical and capacitive, most of the current keyboards are capacitive keyboards. If the keyboard is divided according to its shape, there are two types of ordinary standard keyboard and ergonomic keyboard. The general standard keyboard has a boxy shape, while the ergonomic keyboard adds a wrist tray and divides the main keyboard into two parts according to ergonomic principles. Fatigue is good for health. According to it, there are AT interface (big mouth), PS/2 interface (small mouth), new USB interface and other types of keyboards. In terms of functions, there are ordinary keyboards, multi-function keyboards and so on. The multi-function keyboard adds some function keys on the basis of the ordinary keyboard. Through these function keys, you can operate the computer quickly (such as surfing the Internet, watching VCD, adjusting the volume, turning off the computer or putting the computer to sleep, etc.) to improve work efficiency. When buying a keyboard, you should also pay attention to: 1. Number of keys: No matter which aspect is considered, the 108-key keyboard should be the best choice when purchasing a keyboard. 2. Types of keyboards: As mentioned above, according to the structure of keys, keyboards are divided into two types: capacitive and mechanical. From their characteristics, it can be determined that capacitive keyboards should be purchased. 3. Type of interface: The keyboard interface is divided into two types: AT and PS/2. If you are a new machine, you should buy a keyboard with PS/2 interface, because the newer motherboard does not have an AT interface. You must be careful about this when you buy it. Many people don’t pay attention when they buy it. They leave with the keyboard in their hands without even opening the package. 4. Hand feel: It is difficult to say the hand feel, because everyone feels different, so the keyboard feel can only be known after you have tried it yourself. If others think it is good, you may not be comfortable using it, as long as you try it yourself and think it suits you. 5. The workmanship of the keyboard: The workmanship of the keyboard affects the quality of the keyboard. Whether the workmanship is good or bad can be distinguished from the appearance, whether the surface and corners of the keyboard are finely processed and reasonable. Inferior keyboards have rough appearance and poor key flexibility. Often, a certain key cannot be pressed down, which affects the use. 6. Key arrangement habits: When choosing a computer keyboard, you should consider whether the key arrangement on the keyboard conforms to your habits. Generally speaking, computer keyboards produced by different manufacturers have different key arrangements. For more information on computers check out the Computer Hardware and Equipment Channel
