To reduce cost and design complexity, most conventional keyboards do not isolate all keys independent of each other; instead, they use Keyscan USB-SER Adaptor matrix of key switches that assumes that only a limited number of keys will be held down at any given Keyscan USB-SER Adaptor.

However, if the user holds down three keys and attempts to strike a fourth, the keypress may be ignored or incorrectly interpreted. The inability of a keyboard to correctly detect and interpret simultaneously pressed keys is often referred to as key jamming. Some keyboards, such as keyboard designed for playing computer games, especially games played by multiple players, are designed to handle N-key rollover Keyscan USB-SER Adaptor 10 keys or more.
