In computing, input/output (I/O, i/o, or informally io or IO) is the communication between an information processing system, such as a computer, and the outside world, such as another computer system, peripherals, or a human operator. Inputs are the signals or data received by the system and outputs are the signals or data sent from it.
Example of a klm digital I/O expansion card using a large square chip from PLX Technology to handle the PCI bus interface PCI expansion slot Altair 8800b from March 1976 with an 18-slot S-100 backplane which housed both the Intel 8080 mainboard and many expansion boards Rack of IBM Standard Modular System expansion cards in an IBM 1401 computer using a 16-pin gold plated edge connector first ...
A general-purpose input/output (GPIO) is an uncommitted digital signal pin on an integrated circuit or electronic circuit (e.g. MCUs/MPUs) board which may be used as an input or output, or both, and is controllable by software. GPIOs have no predefined purpose and are unused by default.
SDIO may refer to: . Secure Digital Input Output, a type of Secure Digital card interface.It can be used as an interface for input or output devices. Strategic Defense Initiative Organization, an organization set up to oversee the Strategic Defense Initiative; now known as the Missile Defense Agency.

A magnetic stripe card is a type of card capable of storing data by storing it on magnetic material attached to a plastic card. A computer device can update the card's content. The magnetic stripe is read by swiping it past a magnetic reading head. Magnetic stripe cards are commonly used in credit cards, identity cards, and
High-pin count (HPC), 400 I/O FPGA Mezzanine Card (FMC) connectors Top: mezzanine card side Bottom: baseboard side. FPGA Mezzanine Card (FMC) is an ANSI/VITA (VMEbus International Trade Association) 57.1 standard that defines I/O mezzanine modules with connection to an FPGA or other device with re-configurable I/O capability.
An adapter card or expansion card is a circuit board which is plugged into the expansion bus in a computer to add function or resources, in much the same way as a host bus adapter (see above). [ 3 ] [ 1 ] Common adapter cards include video cards , network cards , sound cards , and other I/O cards.
