Definicija: The complementary tasks of gathering and distributing data. Input is data that is acquired from a device or entered by the user through a device. Output is data that is sent to a device.
Definicija: A channel through which data is transferred between a device and the microprocessor. The port appears to the microprocessor as one or more memory addresses that it can use to send or receive data.
Definicija: The set of essential software routines that test computer hardware at startup, start the operating system, and support the transfer of information between hardware devices. The BIOS is stored in read-only memory (ROM) so that it can be run when the computer is turned on. Although critical to performance, the BIOS is usually invisible to computer users.
Definicija: An application programming interface (API) that can be used by programs on a local area network (LAN). NetBIOS provides programs with a uniform set of commands for requesting the lower-level services required to manage names, conduct sessions, and send datagrams between nodes on a network.
