What is Google cache?

[shockgarden143]

According to my opinion caching is a component that improves performance by transparently storing data closer to end users such that the future requests for that data can be served faster without going back to the origin server. Caching reduces both the load on the origin server as well as speeds up users' online experience.Practically every search result includes a Cached link. Clicking on that link takes you to the Google cached version of that web page, instead of the current version of the page.
