What is the difference between .wbmp and .pam?

Description: The WBMP (Wireless Bitmap Image) file format is a monochrome graphics format optimized for mobile computing devices with limited display capabilities. It was developed for use in the early days of mobile internet to display images on mobile phones and other wireless devices with minimal processing power and storage. WBMP files contain bitmap images that are typically small and use a black and white color palette, making them highly efficient for fast loading times and minimal data usage.; The PAM image format is a lowest common denominator 2 dimensional map format. It is designed to be used for any of myriad kinds of graphics, but can theoretically be used for any kind of data that is arranged as a two dimensional rectangular array.
