What is Caching?
Caching is the practice of storing a copy of data or content temporarily so future requests can be answered faster or with less work.
What it is
Caching means keeping a reusable copy of something so it does not have to be generated or fetched from scratch every time.
Caches are used across browsers, websites, APIs, databases, CDNs, and applications.
How it works
When something is cached, a later request can often be served from the cache instead of hitting the original slower source.
This can reduce latency, save resources, and improve consistency under load.
Why it matters in real life
Caching matters because it is one of the most common ways to improve performance and reduce repeated work.
It affects how quickly websites load, how apps respond, and how infrastructure handles repeated demand.
Common misconceptions
A common misconception is that caching always shows the newest data. In reality, caches can serve older data until they refresh or are invalidated.
Another misconception is that caching only matters for huge platforms. Smaller sites and apps benefit too.
