Let's discuss a few questions about caching, so what it is, and explain the types of caching. We have already discussed in the previous lecture that caching is basically storing useful data on the local device, so that you don't have to fetch the data from the server every time, which makes the application faster. So basically, the main reason to do caching is when we need the data, we don't fetch the data again from the original source, we can use the cached data instead. So we can avoid the expensive process of data fetching. There are many types of caching, which includes browser caching, server side caching, content delivery network caching, database caching, and of course, application caching. By caching the data, we can reduce time latency and load on the servers by not fetching data frequently. Second question, explain different mechanisms of caching which are used by Next.js. So Next.js uses four types of mechanisms for caching the data. First is request memoization, which…
