When buying a computer keyboard, there are several things to consider to ensure that you get a keyboard that meets your needs and preferences. Here are five factors to consider:

- Keyboard Layout: There are different keyboard layouts available, such as QWERTY, AZERTY, and QWERTZ. Make sure to choose a layout that you are comfortable with and familiar with.
- Key Switch Type: There are different types of key switches, such as mechanical and membrane. Mechanical switches offer a tactile feel and are more durable, but are also typically louder and more expensive than membrane switches.
- Connectivity: Keyboards can be connected to a computer through a USB cable, wireless Bluetooth, or other wireless protocols. Choose a connectivity option that works best for your setup and preferences.
- Backlighting: Many modern keyboards come with backlighting, which makes it easier to type in low-light environments. Consider whether you need this feature and choose a keyboard with adjustable lighting levels.
- Additional Features: Some keyboards come with additional features such as programmable keys, multimedia controls, and built-in wrist rests. Consider which additional features are important to you and choose a keyboard that offers them.

Overall, it’s important to choose a keyboard that feels comfortable to use and meets your needs and preferences. Make sure to do your research, read reviews, and try out keyboards in person if possible before making a purchase.
