Question

Plz tell me waht do u mean by cache (what is it ) and is it safe to clear it using a cache cleaner

Answer 1

cache

Pronounced "cash." A cache is used to speed up data transfer and may be either temporary or permanent. Memory and disk caches are in every computer to speed up instruction execution and data retrieval and updating. These temporary caches serve as staging areas, and their contents are constantly changing.

Browser caches and Internet caches store copies of Web pages retrieved by the user for some period of time in order to speed up retrieval the next time the same page is requested (see Web cache and browser cache). See also router cache.

Following are descriptions of the traditional memory and disk caches that are common in all computers.

Memory Caches
A memory cache, or "CPU cache," is a memory bank that bridges main memory and the CPU. It is faster than main memory and allows instructions to be executed and data to be read and written at higher speed. Instructions and data are transferred from main memory to the cache in blocks, using some kind of look-ahead algorithm. The more sequential the instructions in the routine being executed or the more sequential the data being read or written, the greater chance the next required item will already be in the cache, resulting in better performance.

A level 1 (L1) cache is a memory bank built into the CPU chip. A level 2 cache (L2) is a secondary staging area that feeds the L1 cache. Increasing the size of the L2 cache may speed up some applications but have no effect on others. L2 may be built into the CPU chip, reside on a separate chip in a multichip package module (see MCP) or be a separate bank of chips on the motherboard. Caches are typically static RAM (SRAM), while main memory is generally some variety of dynamic RAM (DRAM

Answer 2

All informaton that you read on the web page that is store/download in a temporary folder that called Cache.

Answer 3

Cache, in french it means Hidden. I think here it means Hidden memory.

Answer 4
