💡 Hint

Common Mistakes

Choosing CPU cores or processors instead of storage.

Virtual memory uses disk storage to extend the available memory beyond the physical RAM.

2fill in blank

💡 Hint

Common Mistakes

Thinking virtual memory reduces the number of programs.

Virtual memory allows running more programs than the physical RAM alone can support by swapping data to disk.

3fill in blank

💡 Hint

Common Mistakes

Choosing cache or CPU registers which are faster but smaller.

Virtual memory swaps data to disk storage (like a hard drive or SSD) to free RAM for active tasks.

4fill in blank

hard

Fill both blanks to complete the sentence: Virtual memory uses {{BLANK_1}} to store data temporarily and {{BLANK_2}} to swap data when RAM is full.

Operating Systems

Virtual memory uses [1] to store data temporarily and [2] to swap data when RAM is full.

💡 Hint

Common Mistakes

Mixing up RAM and disk storage roles.

RAM stores data temporarily for quick access, while disk storage is used to swap data out when RAM is full.

5fill in blank

hard

Fill all three blanks to complete the explanation: Virtual memory extends physical memory by using {{BLANK_1}} as extra space, managed by the {{BLANK_2}} which moves data between RAM and disk, allowing the system to run {{BLANK_3}} programs simultaneously.

Operating Systems

Virtual memory extends physical memory by using [1] as extra space, managed by the [2] which moves data between RAM and disk, allowing the system to run [3] programs simultaneously.

💡 Hint

Common Mistakes

Confusing CPU with operating system or disk storage.

Disk storage acts as extra memory space. The operating system manages swapping data. This lets the system run more programs than physical RAM alone.
