An example of a hardware cache is a
cache memory, main memory, and virtual memory. The primary memory is backed by a “DASD” (Direct Access Storage Device), an external high–capacity device. While “DASD” is a name for a device that meets certain specifications, the standard disk drive is the only device currently in use that “fits the bill”.
Primary Cache: The primary cache is located on the processor chip. The cache size is very small and its access time is almost similar to processor registers. Secondary Cache: Secondary cache is placed in the middle of the primary cache and the main memory of the system.
Cache is the temporary memory officially termed “CPU cache memory.” This chip-based feature of your computer lets you access some information more quickly than if you access it from your computer's main hard drive.
How are caches used? Caches are used to store temporary files, using hardware and software components. An example of a hardware cache is a CPU cache. This is a small chunk of memory on the computer's processor used to store basic computer instructions that were recently used or are frequently used.
Everything, from desktop PCs and data centers to cloud-based computing resources, use a fast static random-access memory (SRAM), also called a cache memory, that works alongside the central processing unit (CPU).
There are two different types of cache memory: primary and secondary. Primary cache memory is found on the CPU itself whereas secondary cache memory is found on a separate chip close to the CPU. Although, as time has progressed, the secondary cache has become rather obsolete as most caches are found on the CPU.
Your phone uses the temporary data stored in cache files to quickly recall associated information when you open an app. For example, Spotify might cache your most frequently used playlists so it doesn't have to load the full song lists from scratch each time you open them.
Static random-access memory (SRAM) is used for cache memory.
In computing, a cache is a high-speed data storage layer which stores a subset of data, typically transient in nature, so that future requests for that data are served up faster than is possible by accessing the data's primary storage location.
This cache memory is SRAM (Static RAM) unlike the DRAM (Dynamic RAM) which we find in normal RAM. This SRAM is quite fast compared to DRAM. In computers, we find different levels of cache memory.
Memory holds data and instructions that an executing program frequently accesses -- usually from RAM-based memory locations. The cache provides a small amount of faster memory that's local to cache clients, such as the CPU, applications, web browsers and OSes, and is rapidly accessible.
Difference between RAM and Cache Memory
The cache is faster, cheaper, and smaller than RAM. The cache memory caches CPU data and programs often and quickly. RAM contains the CPU's current data and applications. The cache caches CPU-needed data and programs.
Lazy caching, also called lazy population or cache-aside, is the most prevalent form of caching.
Which of the following is a common cache? Explanation: The translation lookaside buffer is common cache memory seen in almost all CPUs and desktops which are a part of the memory management unit. It can improve the virtual address translation speed.
Cache memory is faster than main memory. It consumes less access time as compared to main memory. It stores the program that can be executed within a short period of time. It stores data for temporary use.
Cached data works by storing data for re-access in a device's memory. The data is stored high up in a computer's memory just below the central processing unit (CPU).

cache. noun. the object of a geocaching treasure hunt. A geocache is usually a small box or item hidden on public or private land, usually with a logbook and trinket.
Cache memory is small amount of RAM located on the CPU itself. It stores commonly used data that is being constantly used by the operating system, allowing for even faster access than the RAM.
While caches help apps load more quickly, cookies help store user preferences, auto-fill form data, and log your browsing history. And that data can pile up as well, so it's good device hygiene to clear your cookies on Android and clear the cache and cookies on your iPhone periodically, too.
Rather than being stored on the server side of things, browser cache is stored on the end-user's side. Every time a user loads a website page, their browser downloads the page's data to show it. Just like website servers, browsers cache most content on a page to shorten load times.
