the compiler normally binds symbolic addresses (variables) to relocatable addresses

the compiler normally binds symbolic addresses to physical addresses

the loader binds relocatable addresses to physical addresses

binding of symbolic addresses to physical addresses normally takes place during execution

it reduces the memory access time to read or write a memory location

it helps to reduce the size of page table needed to implement the virtual address space of a process

it is required by the translation lookaside buffer

it helps to reduce the number of page faults in page replacement algorithms
