What is Cache
 

Hello friends,

Please tell me, What is Cache?

you should search Google for info

When data is found in the cache, it is called a cache hit, and the effectiveness of a cache is judged by its hit rate. Many cache systems use a technique known as smart caching.

Dear Martinricky, Is your question related to google cache or not ? If yes, answer is -

When google cached any website/webpage at that time, it stores a copy version of your website/webpage, which is there in google's system/server that it has captured when it visited your website last.

Hi, I agree with you.

Cache (pronounced cash) memory is extremely fast memory that is built into a computer’s central processing unit (CPU), or located next to it on a separate chip. The CPU uses cache memory to store instructions that are repeatedly required to run programs, improving overall system speed. The advantage of cache memory is that the CPU does not have to use the motherboard’s system bus for data transfer. Whenever data must be passed through the system bus, the data transfer speed slows to the motherboard’s capability. The CPU can process data much faster by avoiding the bottleneck created by the system bus.

Cache is the memory located in the processor.

Cache memory is an extremely fast memory that is built into a computer's central processing unit (CPU). CPU uses cache memory to store instructions that are repeatedly required to run programs, improving overall system speed. Once the data is stored in the cache, future use can be made by using the cached copy alternative re-fetching or recomputing the original data.
