💡 Analysis & Explanation
Core Issue ▼
Computer programs rely entirely on Random Access Memory (RAM) to run actively, but physical RAM is finite and can get exhausted quickly during heavy multitasking.
Technological Solution ▼
To prevent system crashes when RAM fills up, the Operating System employs a specific memory management technique.
Mechanism ▼
It temporarily transfers inactive data pages from the high-speed RAM onto a designated section of the slower hard drive or SSD (called a paging file).
Conclusion ▼
This technique effectively tricks the system into functioning as if it has more memory, meaning its purpose is to extend RAM capacity by using disk space.
