BMP (Bitmap) is very popular nowadays due to the common use of Windows. That is because BMP is the standard format used by Windows for saving image files. It contains more image information than the JPEG, and there is almost no compression of images. So it takes a larger disk space. Presently, 24 bits per pixel BMP files are the most common in all the 1, 4, 8, 15, 24, 32, 64 bits per pixel BMP files. 

DIB is device-independent bitmap, which exchanges DIB between devices and applications with a lot of internal data.

RLE is Run Length Encoding, lossless data compression in bmp format to decrease the file size.
