handles less critical components, such as the PCI, front panel, storage drives, etc.
10firmwarebasic or low-level software used for managing & controlling hardware components
set of system and component instructions
seen as a hybrid between software & hardware
11BIOSBasic Input/Output System
system firmware - set of instructions
responsible for POST
stored on ROM chip on motherboard
32-bit program
12UEFIUnified Extensible Firmware Interface
performs same purpose as BIOS
64-bit program
lays on top of BIOS and adds features like secure boot and the GUID partition table (GPT)
13TPMTrusted Platform Module
chip on motherboard that adds security functions on a hardware level
supports full disk encryption on OSs that have the functionality
14HSMHardware Security Module
physical computing device that provides tamper-evident & intrusion-resistant safeguarding and management of all digital keys and other secrets, as well as crypto-processing
15PCIPeripheral Component Interconnect
type of expansion bus used to connect peripherals, or internal components to the motherboard, through expansion slots
16PCIePCI Express
upgrade for PCI, faster and has the ability to use lanes
17M.2 standarda standard that defines the interface and connector used for internally attached expansion cards and SSDs
commonly 2 - amongst PCIe slots and near SATA connectors
