Basic Input/Output System (BIOS)

The BIOS is built-in software that determines what a computer

can do without accessing programs from a disk. On PCs, the

BIOS contains all the code required to control the keyboard,

display screen, disk drives, serial communications, and a number

of miscellaneous functions at a basic level. Many modern PCs

have a flash (see Flash Memory) BIOS, which means that the

BIOS has been recorded on a flash memory chip, which can be

updated if necessary. The PC BIOS is fairly standardized; so all

PCs are similar at this level (although there are different BIOS

versions). PC BIOSes that can handle Plug-and-Play (PnP)

devices are known as PnP BIOSes, or PnP-aware BIOSes. These

BIOSes are always implemented with flash memory rather than

ROM.

M.2

M.2 is a specification for internally mounted computer expansion

cards and associated connectors. It replaces the mSATA

standard, which uses the PCI Express Mini Card physical card

layout and connectors. M.2 is an edge connector and slides into a

slot that has the corresponding Key ID or notches. This is different

than the typical SATA or even SATA Express connectors we see

used on many storage devices. M.2's more flexible physical

specification allows different module widths and lengths, and,

paired with the availability of more advanced interfacing features,

makes the M.2 more suitable than mSATA for solid-state storage

applications in general and particularly for the use in small

devices such as ultra-thin laptops or tablets.
