what is re-locatable programes
An address that is to be adjusted by the loader when the computer program containing the address is loaded into memory.
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
Some are and some are not. A model of a relacatable program is the DOS .COM file. As a disk file, this program is a binary image of what is loaded in memory. The segment registers are loaded by the operating system, and often were unchanged by the program during operation. It is possible, however, to request more memory from the operating system (or assume the memory is there) and use it, changing the segment registers as required. The non-relocatable program is the .EXE file. In it, segment overrides are not filled in, and must be inserted by the operating system when the program is loaded. Such a file will run anywhere in memory that the operating system puts it, but it must be loaded by the operating system, and the image in memory is not the same as what is on disk.

Partitioned allocation is a fixed memory allocation technique which memory spaces are divided into smaller fixed partition, while Relocatable partitioning use variable and repartitioning technique

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.

To provide readily available and relocatable accommodation for prisoners when the jails were overflowing and exporting them to America was stopped by the War of Independence, decommissioned ships were used.
