.bmp file type #1: Standard bitmap graphics

Common uncompressed bitmap/raster pictures can be often found as files with bmp extension.

Further details:

BMP file, also known as bitmap image file, device independent bitmap (DIB) file format or simply a bitmap, is a raster graphics image file format used to store bitmap digital images, independently of the display device, especially on Microsoft Windows and OS/2 operating systems.

The BMP file format is capable of storing two-dimensional digital images both monochrome and color, in various color depths, and optionally with data compression, alpha channels, and color profiles. The Windows Metafile (WMF) specification covers the BMP file format. However, BMP files are typically larger than other image file formats such as JPEG or PNG, because they store more detailed information. This can make them less suitable for transmitting over the internet or storing on devices with limited storage space.

.bmp file type #2: Alpha Microsystem image

Files with bmp file suffix are related to the Alpha Microsystem bitmap image format.

Further details:

The bmp file extension is used for Alpha Microsystem's image file format.

Alpha Microsystems is a computer company founded in 1977. The first Alpha Micro computer was the S-100 AM-100, based upon the WD16 microprocessor chipset from Western Digital.

Later computers starting with the AM-100/L and the AM-1000 were based on the Motorola 68000 and succeeding processors, though Alpha Micro swapped several addressing lines to create byte-ordering compatibility with their earlier processor.

Very old image format, not to be confused with the bmp file extension (Standard Windows Bitmap image).
