Which of the following describes the operational concept of a 'Virtual Memory'?
A. A cloud-based storage system that bypasses the local operating system.
B. An extremely large main memory array made of high-speed SRAM.
C. An illusion of an extremely large main memory achieved by using a part of secondary storage.
D. A dedicated memory chip installed exclusively inside advanced graphics cards.
Answer: Option C
