What does MB stand for?

MB stands for Megabyte, which is a unit of digital information commonly used in computing and data storage. It represents 1,024 kilobytes, and it is often used to quantify the size of files or the capacity of storage devices. Understanding the concept of a megabyte is foundational in IT, as it allows professionals to evaluate file sizes, storage needs, and make decisions regarding data management.

The other choices present variations that are not commonly accepted or indicative of standard digital measurements. For example, "Medium Byte" and "Measurement Byte" do not correspond to recognized units in data measurement, while "Mega Bit" refers to a different unit entirely, typically used to measure data transfer rates, which can lead to confusion with megabytes.
