what is cache memory?

Answer 1

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. . .

Answer 2

Memory Stored in the Temporary portion on Ram is Called Cache Memory

Answer 3

A dedicated memory for copying a portion of system memory targeted for immediate use. They are very fast and pricy to have compare to main system RAM, there are 2 cache memories, L1 and L2, L1 is even faster than L2 types and located within CPUs.

First generation Celerons didn't even have L2 and that attributes to the slowness so Intel put some L2 back into the blueprint of newer Celerons and there once were a Mac outfited with outrageously large L2 that made it gone overdrive.

Answer 4

Cache is small amount of extremely fast memory, that runs on processor speed, these memory reffered as L1, L2, L3. These are very fast memories, it is used to store instruction temporarily just for few miliseconds. Cache memory takes data from RAM and seeds it to Processor or Vise Versa. Cache resides between Processor and RAM. These are small amount of fast memories like 512kb, 1mb, 2mb.
Cache memories runs on a operational Logic "If processor using a data on one address of memory, than it is more possible that it will asks for next data from neighbourehood address in future. Then cache catches(stores) all data from neighbour addresses of the address on processor is currently working. "
These mem's are used in pairs like L1 and L2 or more L3 also. This is to minimize the effect of slow RAM and HDD speed from processor. L1 runs on processor speed, L2 is less faster than L1 but more than RAM. In this case L2 takes neighbour address data from RAM, then L1 takes neighbour address data from L2.

Answer 5

When your computer is executing a job, it stores some data in the RAM for further quick access use. When you turn off your computer the data is lost. Its just for the system to operate faster. The larger your RAM the better for your system.

Answer 6

A place where stuff is stored for possible later use.
