PC Keyboard Types

A variety of keyboards are available to use with a personal computer, or PC. The keyboard houses a number of keys that allow you to access the computer in various ways and type on it. The PC keyboard is a descendant of the typewriter, and its setup is quite similar. Some keyboards are basic, with letters, numbers and symbols. Other keyboards are far more complex, with keys that can help you play games and flexible designs that allow the keyboard to be rolled up. Key factors in choosing a keyboard are that it be comfortable and functional.

1. Gaming Keyboards

  • Gaming keyboards are designed for users who frequently play computer games. They typically are equipped with features that can make game play easier and more accessible. For instance, according to the Computer Hardware Explained website, gaming keyboards typically come with palm rests, LED screens, multimedia keys and a variety of other features for gaming. Some even have illuminated keys, which can make game playing easier in a dark room. The multimedia keys typically can adjust the volume and allow you to complete other tasks while still playing the game.
  • Carpal tunnel syndrome is a condition that can affect people who frequently type on keyboards. Ergonomic keyboards are designed to prevent carpal tunnel syndrome and other conditions caused by heavy keyboard use. These types of keyboards can reduce the strain on the wrists and increase the overall comfort of users. Ergonomic keyboards usually have a built-in wrist rest with a downward slope to prevent the user's wrists from hanging off the keyboard, which can cause strain.
  • Roll-up keyboards are an alternative for PC keyboards that have gained popularity as of 2010. Usually made of silicone or polyurethane, roll-up keyboards are useful for those who travel, as the keyboard can be stored easily. Roll-up keyboards work as effectively as a traditional style keyboard and are good for users who move around a lot and require portability, according to the Computer Hardware Explained website.
