What is meant by cache memory?

Answer 1

Cache memory is random access memory (RAM) that a computer microprocessor can access more quickly than it can access regular RAM. As the microprocessor processes data, it looks first in the cache memory and if it finds the data there (from a previous reading of data), it does not have to do the more time-consuming reading of data from larger memory.
Cache memory is sometimes described in levels of closeness and accessibility to the microprocessor. An L1 cache is on the same chip as the microprocessor. (For example, the PowerPC 601 processor has a 32 kilobyte level-1 cache built into its chip.) L2 is usually a separate static RAM (SRAM) chip. The main RAM is usually a dynamic RAM (DRAM) chip.

In addition to cache memory, one can think of RAM itself as a cache of memory for hard disk storage since all of RAM's contents come from the hard disk initially when you turn your computer on and load the operating system (you are loading it into RAM) and later as you start new applications and access new data. RAM can also contain a special area called a disk cache that contains the data most recently read in from the hard disk.

What Is Cache Memory

Answer 3

There are different types of memory used by modern computers. These different types of memory vary greatly in their speed and, most importantly, in their price. DRAM, or dynamic ram, is a slower cheaper type of memory. Another type of memory is SRAM, or static ram. The cache is quick memory used by the computer to speed up memory accesses for processes. It is often comprised of small amounts of expensive SRAM. In modern computers, in order to cram as much quick memory as possible into the computer, there exists a memory heirarchy. It looks a little like this. 1-Registers 2-Cache(any levels or amounts of it) 3-Main Memory(DRAM) 4-Hard Disk 5-Network Drives There may be more, but thats the basic idea. Cache is not quite as fast as a register(the quickest memory), but much faster than main memory.

Answer 4

Cache memory is a temporary memory which stores more frequently used items. There is a cache memory in your internet browser, in every processor and so on. In the browser, it helps in loading pages easily because if the page at the server is the same as the one you last loaded, then you donot need to download it, you can view it from your browser cache. In your processor, some frequently used items need to be used by the processor quite frequently. It takes time to fetch them agaain and again if they are stored in hard disk or RAM, so they are stored on a memory which is inside the processor ans hence easily accessible and called cache of processor.

Answer 6

cache memory. is the High spped memory. faster than RAM speed. due its cost manfactures keep very low capacity of it in System.

Advantage of cache is that, when ever CPU requires some instruction or data it first checks in cache. if it present then it will be provided at fast rate. if not fecthed from RAM and keept in chache. (explanation goes technical)

Answer 7

Cache is a french word that means "hidden" The definition of cache memory is hidden memory.

Answer 8

To increase efficiency, the computer doesn't always write everything to disk as it is requested it. It builds it up (caches it) and writes it all in one go.

Answer 9

Its like a waiting room for processes (data), before the the process go to the main circuit(s) of processing (in most cases the more you have the faster your computer will be including if its on the processor)

Answer 10

The system should be have memory catcher but it could PE the more power full
