They can use different I/O protocols, but SPI is the most common. Unified Extensible Firmware Interface ( UEFI, / ˈjuːɪfaɪ / or as an acronym) [ b] is a specification that defines the architecture of the platform firmware used for booting the computer hardware and its interface for interaction with the operating system.
Computer hardware. PDP-11 CPU board. 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]
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).

Peripheral Component Interconnect ( PCI) [ 3] is a local computer bus for attaching hardware devices in a computer and is part of the PCI Local Bus standard. The PCI bus supports the functions found on a processor bus but in a standardized format that is independent of any given processor 's native bus. Devices connected to the PCI bus appear ...
All-in-one computer. An all-in-one computer (also called an AIO or all-in-one PC) is a type of personal computer that integrates the computer components, such as the CPU, monitor, and speakers, into a single unit. It occupies a smaller footprint than a desktop computer with a tower form factor, and also uses fewer cables. [ 1][ 2][ 3]
Just in case you've seen that web page floating around implicating Dell in some wacked out government conspiracy by suggesting they fit a 4mb keylogger between the keyboard end of some guy's 600m ...
Firmware. Firmware is commonly stored in an EEPROM, which makes use of an I/O protocol such as SPI. In computing, firmware is software that provides low-level control of computing device hardware. For a relatively simple device, firmware may perform all control, monitoring and data manipulation functionality. For a more complex device, firmware ...
Input/output. v. t. e. In the context of an operating system, a device driver is a computer program that operates or controls a particular type of device that is attached to a computer or automaton. [ 1] A driver provides a software interface to hardware devices, enabling operating systems and other computer programs to access hardware ...
