Common keyboards can be mainly divided into two types: 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 shape of the ordinary standard keyboard is square, but the ergonomic keyboard adds a wrist tray according to the ergonomic principle, and divides the main keyboard into two parts. Fatigue is good for health.
According to it, there are AT interface (large 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, keep in mind:
1. The number of keys: No matter which aspect is considered, the 108-key Windows 98 keyboard should be the best choice for purchasing keyboards today.
2. Types of keyboards: As mentioned above, according to the structure of the keys, the keyboards are divided into two types: capacitive and mechanical. From their characteristics, it can be determined that capacitive keyboards should be bought.
3. Type of interface: The keyboard interface is divided into three types: AT, PS/2, and USB interface (AT interface has been eliminated). If you are a new machine, you should buy a keyboard with PS/2 interface, because newer motherboards do not have AT interface. You must be optimistic about this when you buy it. Many people don’t pay attention when they buy it. They leave with the keyboard without even opening the package.
4. Hand feel: It’s hard to say the hand feel, because everyone feels different, so the feel of the keyboard 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 the keys are not flexible. Often, a certain key cannot be pressed, 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.
