No, it does not.
It depends if you are using a basic disk or dynamic disk( you can go to your drive and convert it from basic to dynamic but if you go from dynamic to basic it will destroy all data you have on it) dynamic disk can have more partitions although with dynamic it calls partitions volumes

Relocatable dynamic fragmentation is caused by the repeated allocation and deallocation of memory blocks of varying sizes, leading to small gaps that may not be reused efficiently due to mismatches in size requirements. Over time, this can result in a high level of fragmentation and a decrease in memory utilization efficiency.
relocatable code is code where final output of the assembly phase,ready to be used an input to loader. self relocatable is the code where output of the code is ready to use any point
what is re-locatable programes
Virtual Machines commonly use dynamically expanding storage. Additionally, Linux can use LVM, which allows dynamic resizing of sub-partitions.
Fixed partitions have fixed size and usually cannot be easily expended or shrunk. Dynamic partitions can change size by themselves when they need it. There are some advantages of using fixed partitions because you control its size. It might happen that you can run out of free space when you are using dynamic partitions.
