What is cache

[Brown]

Can someone tell me what cache is and what does it do for the computer ? I know it works with internet and cookes also disk clean up .

When I think Cache I think how much cache a CPU has.  Not totally sure what it does (Gonna go read up I think) but I do know the more cache your CPU has the faster it will work.

All I know is you can think of CPU cache as CPU RAM, it stores the things the CPU needs in it to get a process done...

 Cache is where the CPU stores info it uses frequently so it doesn't have to look in the systems RAM or on the HDD, so yes, it is like the CPU's personal memory bank.

Depends on what kind of cache you are talking about.

CPU cache (usually with a designation like l1 or l2 or l3) are on-die extremely fast memory used to store frequently accessed data.

Internet cache is a certain space on the hard drive used by internet browsing applications to store offline content and interactive content (such as flash plugins or cookies)

There are other forms of cache too, so you'll have to be more specific as to your question.
