Yes - it's the card file format. FAT is the file format most commonly seen on DOS or early Windows systems, although it was adopted by several other small computers (including, most relevantly, embedded systems such as those used in digital cameras). It is capable of handling file systems of up to 2GB in total size - a number that seemed almost inconceivable at the time FAT was first introduced.
But time (and technology) wait for no man, and it wasn't that long before hard drives larger than 2GB began to show up. To handle that (and to deal with some other limitations of the FAT format, none of which are relevant to in-camera use) FAT32 was introduced as a minimal upgrade to FAT, using pretty much the same concepts.
