The correct answer is: A. Paging
Paging is a memory management technique that allows a computer to access more memory than is physically present in the computer's memory. Paging works by dividing the computer's memory into small blocks called pages. When a program needs to access a page that is not currently in memory, the operating system will swap the page that is currently in memory with the page that the program needs. This process is called page swapping.
Paging is a very efficient way to manage memory, and it is used in most modern operating systems.
The other options are incorrect because:
- B. Interleaving is a technique that is used to improve the performance of a computer's memory by interleaving the memory addresses of different memory banks. This allows the computer to access memory more quickly.
- C. RAM is a type of computer memory that is used to store data and programs that are currently being used by the computer.
- D. External storage is a type of computer storage that is used to store data and programs that are not currently being used by the computer.
