It is the set of logical addresses that a process references in its code.

• Process Address Space

• Physical Addresses

• Symbolic Addresses

• Memory management

It keeps track of each and every memory location, regardless of either it is allocated to some process or it is free.

• Process Address Space

• Physical Addresses

• Symbolic Addresses

• Memory management

The Addresses used in a source code. The variable names, constants and instruction labels are the basic elements of the symbolic address space.

• Process Address Space

• Physical Addresses

• Symbolic Addresses

• Memory management

The loader generates these addresses at the time when a program is loaded into main memory.

• Process Address Space

• Physical Addresses

• Symbolic Addresses

• Memory management

It is the functionality of an operating system which handles or manages primary memory and moves processes back and forth between main memory and disk during execution.

• Process Address Space

• Physical Addresses

• Symbolic Addresses

• Memory management

At the time of compilation, a compiler converts symbolic addresses into relative addresses.

• Relative Addresses

• Linker

• Dynamic Linking

• Static Linking

It combines the object program with other necessary object modules into an absolute program, which also includes logical addresses.

• Relative Addresses

• Linker

• Dynamic Linking

• Static Linking

When this type of linking is used, it is not required to link the actual module or library with the program, rather a reference to the dynamic module is provided at the time of compilation and linking.

• Relative Addresses

• Linker

• Dynamic Linking

• Static Linking

When this type of linking is used, it is not required to link the actual module When this type of linking is used, the linker combines all other modules needed by a program into a single executable program to avoid any runtime dependency.

• Relative Addresses

• Linker

• Dynamic Linking

• Static Linking

It is a mechanism in which a process can be swapped temporarily out of main memory (or move) to secondary storage (disk) and make that memory available to other processes.

• Swapping

•  Low Memory

• Multiple-partition allocation

• Single-partition allocation
