What is the "cache"?

Answer 1

Cache is the High speed memory present between the CPU and RAM (main memory). It contains the recent instructions read by the CPU, and CPU retrieves from cache when next time the same intructions are needed.

Answer 2

From the hardware perspective, a cache is a relatively small and fast memory placed between the processor and main memory(RAM). Whenever some instruction/data is fetched from the RAM, the corresponding block is placed in the cache. The next time, the data will possibly be available in the cache, and hence memory access time is reduced.

From a software viewpoint a cache is a place on your disk where web pages are stored by the browser. When you want to open the same page again, it is opened from the cache rather than having to transfer the whole thing from the server.

In general you can think of the cache as a place where frequently accessed data is stored for fast retrieval.

Answer 3

A cache (pronounced CASH) is a place to store something temporarily. The files you automatically request by looking at a Web page are stored on your hard disk in a cache subdirectory under the directory for your browser (for example, Internet Explorer). When you return to a page you've recently looked at, the browser can get it from the cache rather than the original server, saving you time and the network the burden of some additional traffic. You can usually vary the size of your cache, depending on your particular browser.
Computers include caches at several levels of operation, including cache memory and a disk cache. Caching can also be implemented for Internet content by distributing it to multiple servers that are periodically refreshed. (The use of the term in this context is closely related to the general concept of a distributed information base.)

Altogether, we are aware of these types of caches:

International, national, regional, organizational and other "macro" caches to which highly popular information can be distributed and periodically updated and from which most users would obtain information.
Local server caches (for example, corporate LAN servers or access provider servers that cache frequently accessed files). This is similar to the previous idea, except that the decision of what data to cache may be entirely local.
Your Web browser's cache, which contains the most recent Web files that you have downloaded and which is phyically located on your hard disk (and possibly some of the following caches at any moment in time)
A disk cache (either a reserved area of RAM or a special hard disk cache) where a copy of the most recently accessed data and adjacent (most likely to be accessed) data is stored for fast access.
RAM itself, which can be viewed as a cache for data that is initially loaded in from the hard disk (or other I/O storage systems).
L2 cache memory, which is on a separate chip from the microprocessor but faster to access than regular RAM.
L1 cache memory on the same chip as the microprocessor.

Answer 4

It is a folder that places files for quicker loading. For example, on the internet, if you load a page with pictures, the pictures are temporarily stored in a cache folder on your PC. The next time you visit the site, the pictures will load quicker because it is taking it from the cache.

Answer 5

Cache is the memory type. whenever CPU searches something it will first search it in cache then moves to HardDisk. So whatever links you look often it naturally referenced in cache for faster search & access. But it is volatile memory just as RAM.

Answer 6

It makes your computer remember images and such so it loads faster when visiting a web page. It's good to clear the cache every once in a while though, as it does eventually slow down your computer in the long run.

Answer 7

cache like for HDD and procesors ..is a memory like the Ram memory but faster

for procesors for ex P4 2.8 GHz with 2M cashe is better then a Celeron 3.06 GHz with 512K cashe

simple is the memory that is filled and then empty on to the RAM ...the biger the beter
