Which of the following addressing modes are suitable for program relocation at run time?
$$1.$$ Absolute addressing
$$2.$$ Based addressing
$$3.$$ Relative addressing
$$4.$$ Indirect addressing

Consider a program $$P$$ that consists of two source modules $${M_1}$$ and $${M_2}$$ contained in two different files. If $${M_1}$$ contains a reference to a function defined in $${M_2}$$, the reference will be resolved at.

The minimum number of page frames that must be allocated to a running process in a virtual memory environment is determined by.

In a system with $$32$$ bit virtual addresses and $$1$$ $$KB$$ page size, use of one-level page tables for virtual to physical address translation is not practical because of
