Musical Instrument Digital Interface




(MIDI) Adapter Cards













• A musical instrument digital interface (MIDI) card




is a piece of computer hardware that allows a user to




connect musical instruments and similar devices



through a MIDI connector to a computer.






• This is typically done to use a computer to record music,




especially for use in a MIDI format.






• The sound card may also often act as a standard sound




card as well, allowing connection of microphones,




speakers and similar devices.

Operating System












• Different sizes of computers typically use




different operating systems because operating




systems generally are written to run on a specific




type of computer.






• For example, a mainframe computer does not




use the same operating system as a personal




computer.






• The same types of computers, such as desktop




computers also may not use the same operating




system.
