What is the difference between disk cache and memory cache?

What is the difference between disk cache and memory cache?

Disk cache is a storage area on a hard drive that temporarily holds data, while memory cache is a faster, smaller storage in RAM.

Which one is faster and why?

Memory cache is faster because it uses RAM, which has quicker access times compared to disk storage.

When should I use disk cache instead of memory cache?

Use disk cache for larger data sets that don't fit in memory or for data that needs to persist after a reboot.

Can you give examples of applications that use each type?

Web browsers often use disk cache for storing images and files, while CPU caches use memory cache for quick data access.
