Caching

What is Caching?

• A mechanism that stores data or results in advance so that they can be accessed or reused more quickly later.

Advantages of Caching

• Data stored in the cache is located in a faster storage area, so it can be accessed more quickly than fetching data directly from the original source.

• When there are many repeated accesses to the same data, using a cache can reduce system load compared to accessing the original data storage every time.

• Caching can also reduce network traffic by fetching data from the cache instead of the original data source.

Examples of Caching Usage

• A web browser caches images, scripts, and style sheets of web pages in a local storage so that the next time the same page is visited, it loads faster.

• Caching is used in both hardware and software, such as memory caches in programming, database query result caches, and web page caches in browsers.
