MB
Abbreviation for megabyte
In short and in plain language
MB stands for megabyte. It is a unit for an amount of data.
It gives the size of a file. This can be an image, a video or a sitemap.
Large files load more slowly. This is most true on mobile networks. So images for a site are usually made smaller. They are also compressed.
