What is called “a disk” might, physically, be more than one disk – and may be more than one device (such as RAID); we don’t really care, here.
Similarly a ‘single’ disk may be logically divided into partitions.
A partition is a virtual disk which is mapped onto a physical one. These may still be combined within the same file system.
Different partitions may serve different purposes. For example one partition could be file store whilst another is used for page swapping. Different algorithms and permissions could be applied to different partitions.
