About keyboards

five common types of keyboard designs.

§          Traditional keyboards: full-sized, rigid, rectangular keyboards that include function, navigational, and numeric keys.
§          Flexible keyboards: fold or roll up for easy packing and storage for mobile users.
§          Ergonomic keyboards: similar to traditional, but designed to specifically alleviate wrist strain associated with repetitive movements of typing.
§          Wireless keyboards: more expensive than traditional keyboards, but give the flexibility of un-tethering the cord.
§          PDA keyboards: miniature keyboards for PDAs for sending email, etc


some common keyboard features

  • Numeric keypads: easier entry of numbers and arithmetic symbols
  • Toggle keys: on off keys for such things as <Caps Lock> and <Scroll Lock>
  • Combination keys: perform an action when combined with other keys, e.g. <Ctrl> key or <Alt> key
