Dell 9200 HD partitions

I was planning to add a partition to my HD so I could have an alternate Linux (ubuntu) OS. I haven't done anything yet.

When I examined the HD with Easeus Partition Master it shows three partitions:
Partition Type Size Used Status Pri/Log
* FAT16 47MB 7MB None Primary
C: NTFS 108GB 54GB System Primary
* FAT32 4GB GMB None Primary

I understand the NTFS, but why are there FAT16, and FAT32 segments? Are these actual partitions? Can they be removed? Neither of the FAT segments amount to much space, I just would like to know why they are there.

I just looked at my Dell 531 desktop and there is a similarly sized FAT16 segment, but no FAT32.

 

A lot of pre-made, name brand computers have a recovery partition so you can restore the computer to how it originally came if you had an issue that forced you to reinstall your OS.
