UEFI. In computing, BIOS ( / ˈbaɪɒs, - oʊs /, BY-oss, -ohss; Basic Input/Output System, also known as the System BIOS, ROM BIOS, BIOS ROM or PC BIOS) is firmware used to provide runtime services for operating systems and programs and to perform hardware initialization during the booting process (power-on startup).

Computer hardware includes the physical parts of a computer, such as the central processing unit (CPU), random access memory (RAM), motherboard, computer data storage, graphics card, sound card, and computer case. It includes external devices such as a monitor, mouse, keyboard, and speakers. [ 1][ 2]
v. t. e. 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.
API. Audio Stream Input/Output ( ASIO) is a computer sound card driver protocol for digital audio specified by Steinberg, providing a low- latency and high fidelity interface between a software application and a computer's sound card. Whereas Microsoft 's DirectSound is commonly used as an intermediary signal path for non-professional users ...
Machine code is by definition the lowest level of programming detail visible to the programmer, but internally many processors use microcode or optimize and transform machine code instructions into sequences of micro-ops. Microcode and micro-ops are not generally considered to be machine code; except on some machines, the user cannot write ...
Another Unix breakthrough was to automatically associate input and output to terminal keyboard and terminal display, respectively, by default [citation needed] — the program (and programmer) did absolutely nothing to establish input and output for a typical input-process-output program (unless it chose a different paradigm).
Command-line interface. A command-line interface ( CLI) is a means of interacting with a computer program by inputting lines of text called command-lines. Command-line interfaces emerged in the mid-1960s, on computer terminals, as an interactive and more user-friendly alternative to the non-interactive interface available with punched cards ...
In computer science, the general meaning of input is to provide or give something to the computer, in other words, when a computer or device is receiving a command or signal from outer sources, the event is referred to as input to the device. Some computer devices can also be categorized as input devices [ 1] because we use these devices to ...
