Answer:

ASP.Net Caching is a mechanism to store the frequently used data into the server memory which can be retrieved very quickly. And so provides both scalability and performance. For example if user is required to fetch the same data from database frequently then the resultant data can be stored into the server memory and later retrieved in very less time (better performance). And the same time the application can serve more page request in the same time (scalability).

But it also have some drawbacks. Suppose the server memory is filled with the data then the remaining part of the data is stored into the disk which slow down the complete system performance. That's why self limiting caching techniques are best; where once the server memory gets filled the data has been selectively removed from the server memory to ensure that the application performance is not degraded.
