What does bmp mean in computer terms?

The BMP file format, sometimes called bitmap or DIB file format (for device-independent bitmap), is an image file format used to store bitmap digital images, especially on Microsoft Windows and OS/2 operating systems. Many graphical user interfaces use bitmaps in their built-in graphics subsystems;[1] for example, the Microsoft Windows and OS/2 platforms' GDI subsystem, where the specific format used is the Windows and OS/2 bitmap file format, usually named with the file extension of .BMP or .DIB (source Wikipedia) or basic metabolic panel (BMP), a group of 8 tests used as a general screening tool. (You probably are looking for the latter lol)
