For better absorption of the principle of its operation, consider the example of the library, which employs only one librarian. See, when the reader comes to the library and ask the librarian to bring him a book, for example, LN Tolstoy’s “War and Peace”, the latter rises from his desk, goes to the correct rack at the end of the hall and brings a necessary book, when the book returns, everything is exactly the same – the librarian gets up and carries “War and Peace” in the back of the room in its place, then comes back, and it happens every time this book asks a reader. By the same token the computer without using the cache provides the user files from your memory.

Now imagine that the return of books, librarian took it into place, and put on my desk. In this case, re-request the reader to bring the famous novel by Leo Tolstoy, the librarian will not have to go and spend time on it. Simply reach out and take the book off the table. If you go back to the cache, the table here is just and will be it. That is, the cache keeps those files that computer processor accesses most often. And everything is so thought out that not only temporarily stored these files, but also those who are close to him. If you go for clarity in our library, it means going beyond the first volume of “War and Peace” with a librarian take over all the others and put them on my desk, and suddenly, after reading the first volume, you will want to read the second and then the third and etc.
