It is different than the external memory model because cache-oblivious algorithms do not know the block size or the cache size. In particular, the cache-oblivious model is an abstract machine (i.e., a theoretical model of computation). It is similar to the RAM machine model which replaces the Turing machine's infinite tape with an infinite array.
Docker is a set of platform as a service (PaaS) products that use OS-level virtualization to deliver software in packages called containers. [5] The service has both free and premium tiers. The software that hosts the containers is called Docker Engine. [6] It was first released in 2013 and is developed by Docker, Inc. [7]
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).
The hit ratio of a cache describes how often a searched-for item is found. More efficient replacement policies track more usage information to improve the hit rate for a given cache size. The latency of a cache describes how long after requesting a desired item the cache can return that item when there is a hit.

The TLB is a cache of the page table, representing only a subset of the page-table contents. Referencing the physical memory addresses, a TLB may reside between the CPU and the CPU cache, between the CPU cache and primary storage memory, or between levels of a multi-level cache. The placement determines whether the cache uses physical or ...
apt-get and apt-cache are command tools of the standard apt package. apt-get installs and removes packages, and apt-cache is used for searching packages and displaying package information. [119] Aptitude is a command line tool that also offers a text-based user interface. The program comes with enhancements such as better search on package ...
The inner [] brackets indicate actual cache, which although fixed in size, can move freely across the B1 and B2 history. L1 is now displayed from right to left, starting at the top, indicated by the ! marker. ^ indicates the target size for T1, and may be equal to, smaller than, or larger than the actual size (as indicated by !).
