What is Caching?
Frequently used data is temporarily stored in memory for quick access.
Overview
Caching is an acceleration method used to prevent a system from repeatedly calculating the same data or pulling it from a remote source. Data is copied to a quickly accessible area (cache) and served from there when needed. This significantly reduces the overall response time of the system.
How it works
When the system requests data, it first looks at the cache; If the data is there, it retrieves it immediately, otherwise it pulls it from the main source and leaves a copy in the cache.
Where it is used
It is widely used to improve performance in web browsers, applications, and large-scale data centers.
Commonly confused with
It can be confused with a database, but cache is temporary and fast, while database is permanent and larger.
Frequently asked questions
What happens if the cache becomes full?
Old or rarely used data is deleted and replaced with new data.
