Final answer:
The term 'M.2' refers to a type of computer storage device, which is a form factor of solid-state storage. Designating the compact and high-speed memory devices found in modern PCs, M.2 utilizes the megabyte as a basic measurement of storage capacity.
Step-by-step explanation:
“M.2” is a type of computer storage device. With regard to computer memory and storage, prefixes like kilo (K), mega (M), giga (G), etc., help denote different quantities. The basic unit of computer memory is the byte (b), and the unit for one million bytes is a megabyte (MB). Drawing a parallel with the metric system and its usage of prefixes, just like how a millimeter (mm) is used to measure small distances, megabyte is useful to denote large amounts of data in computers. M.2 drives provide high-speed storage solutions and are compact in size, making them increasingly popular in modern personal computers and laptops.
