What is the most commonly used cache?
- A.
Rom Cache
- B.
Wallet Cash
- C.
Disk Cache
- D.
Web Browser Cache
Correct Answer
D. Web Browser CacheExplanation
The most commonly used cache is the web browser cache. This cache stores temporary files, such as images, scripts, and stylesheets, from websites that a user visits. By storing these files locally, the web browser can load the website faster upon subsequent visits, as it does not need to download all the files again. This improves the overall browsing experience and reduces the amount of data that needs to be transferred over the internet.Rate this question:
