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 ...
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).

It includes external devices such as a monitor, mouse, keyboard, and speakers. [ 1][ 2]
Unified Extensible Firmware Interface (UEFI, / ˈ juː ɪ f aɪ / 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.
Hypervisor. A hypervisor, also known as a virtual machine monitor ( VMM) or virtualizer, is a type of computer software, firmware or hardware that creates and runs virtual machines. A computer on which a hypervisor runs one or more virtual machines is called a host machine, and each virtual machine is called a guest machine.
A device driver is a computer program encapsulating, monitoring and controlling a hardware device (via its Hardware/Software Interface (HSI)) on behalf of the OS. It provides the operating system with an API, procedures and information about how to control and communicate with a certain piece of hardware.
The following outline is provided as an overview of and topical guide to software: Software – collection of computer programs and related data that provides the information for the functioning of a computer. It is held in various forms of memory of the computer. It comprises procedures, algorithms, and documentation concerned with the ...
