A block of memory cannot necessarily be placed at an arbitrary location in the cache; it may be restricted to a particular cache line or a set of cache lines [1] by the cache's placement policy. [2] [3] There are three different policies available for placement of a memory block in the cache: direct-mapped, fully associative, and set-associative.
In computing, cache replacement policies (also known as cache replacement algorithms or cache algorithms) are optimizing instructions or algorithms which a computer program or hardware-maintained structure can utilize to manage a cache of information. Caching improves performance by keeping recent or often-used data items in memory locations ...
If you would like to keep your data in your cache and test Wikipedia with an empty cache, you can use Private Browsing mode. To disable caching in Firefox (not recommended for most users): Choose Tools Options… (or Edit Preferences in the Linux version). Choose "Advanced" at the top. Choose the "Network" tab. Change the cache size to 0 (zero).
Bypass your cache — Simple instructions In most Windows and Linux browsers: Hold down Ctrl and press F5. In Apple Safari: Hold down ⇧ Shift and click the Reload toolbar button. In Chrome and Firefox for Mac: Hold down both ⌘ Cmd+⇧ Shift and press R. See full instructions below

The Time aware Least Recently Used (TLRU) [1] is a variant of LRU designed for the situation where the stored contents in cache have a valid life time. The algorithm is suitable in network cache applications, such as information-centric networking (ICN), content delivery networks (CDNs) and distributed networks in general.
Diagram of a CPU memory cache operation. In computing, a cache (/ k æ ʃ / ⓘ KASH) [1] is a hardware or software component that stores data so that future requests for that data can be served faster; the data stored in a cache might be the result of an earlier computation or a copy of data stored elsewhere.
A CPU cache is a hardware cache used by the central processing unit (CPU) of a computer to reduce the average cost (time or energy) to access data from the main memory. [1] A cache is a smaller, faster memory, located closer to a processor core, which stores copies of the data from frequently used main memory locations.
