What is Caching
Dated: 25 Nov, 2010 07:35:37 PM
Caching is a strategy whereby the application temporarily stores that data locally to improve its performance. The local location can be memory or local hard disk depending on the scenario.
For example,
- when we visit a website, internet explorer caches the page on the hard disk (local compared to the server).
- Likewise, when we load a large document in word, it caches the document contents in memory (instead of reading the data from hard disk every time you scroll the page).
These caching strategies improve the application performance and hence user experience (web page will load quickly and the scrolling will be quick in word).
