Cache memory (not Catche) is very fast memory that is built into the processor itself. This memory stores recently executed instruction streams and pre-fetched instruction streams to speed up processing. In this way the processor does not have to read the instruction stream from the slower system memory, but can access it from the on-board very fast memory instead. Cache memory is most effective for loops and small sized repetitive code, such as interrupt routines etc.
These days most processors have 2MB or more of primary cache. Previously there used to be primary and secondary cache where the primary was built into the processor and the secondary was implemented on the motherboard using very fast memory ICs. However, these ICs are still not as fast as the memory on the processor itself.

Lose the "t" in spelling, it's the memory that go between some fast active processor (CPU) and painfully slow memory storage (RAM, DDR3 consider to be that slow too) so that CPU is not bogged down by RAM everytime it needs some small amount of data from memory.

It's the memory that comes with processors to access faster rather than going to ram. It was introduced because processors have always evolved faster than ram, and there isn't much point on having slow ram bog down a fast processor.

to give you an example, say you're playing a PC game and you enter a new area(map), it takes awhile to load up that new area. however, notice that when you exit that area then come back, it won't take as long to load up. that's cache memory ^_^
basically it stored the data of the area so that when u return to that same area, it won't take as long to load.
the same concept is applied to other computer softwares. notice sometimes, you will load up a software and it will take very long to load, but if u exit the software then immediately run it again, it will not take as long to load up.

that is memory where a computer puts data that it will most likely use next.

its the memory that your ram/cpu keeps stored so it can use it later and access it quicker
