Cache
Definition
Saved copies of website data stored locally to speed up repeat visits.
In Plain English
Cache is like keeping a photocopy of a frequently used document on your desk instead of walking to the file room every time.
Real-World Example
After a customer visits your site once, their browser saves images and files locally, making the next visit much faster.
Why It Matters for Your Work
Good caching dramatically improves site speed. But it can also cause visitors to see outdated content after updates.
Common Mistake
Not clearing cache when troubleshooting. "Have you tried clearing your cache?" is step one for website issues.
