Getting data from memory, or the hard drive is slow. If you store a part of the memory you think you will need soon, or often in cache, it will speed up processing by reducing wait time. Cache is much smaller, but much faster than memory and sits on the processor die.
What else can I help you with?
How does memory cache speed up computer processing A Cahce memory doesn't need to be refreshed so access time is faster B Cache memory refreshes instantly so acess time is faster. C Cache memory uses?
A
What is off-line processing of files in computer?
Offline processing refers to processes being redirected from the central processing unit cache into the random access memory units. Speed of processing is inversly proportional to the clock speed of the memory bus in the cpu.
What is the impact of a cache miss penalty on the performance of a computer system?
A cache miss penalty occurs when the CPU needs data that is not in the cache memory, causing a delay as it fetches the data from the slower main memory. This delay can significantly impact the performance of a computer system by slowing down processing speed and increasing latency in executing tasks.
Difference between cache memory and ram?
RAM (Random Access Memory) is used to store information for the programs running now while the computer is powered. Cache memory is RAM that a computer microprocessor can access more quickly than it can access regular RAM.
Is The CPU uses a special type of random access memory known as cache memory to speed up processing?
It depends entirely.
Why does the speed of a computer increase as soon as we increase the size of the cache memory?
Basically for the same reason that cache itself helps increase the speed. If there is more cache memory, the computer will have more information readily available, and there will be less cases where the information CAN'T be found in cache, and the CPU needs to access actual RAM, which is slower (or whatever other source of data the cache is supposed to speed up).
What if Cache size is equal to main memory size?
If we took size of cache as large as size of main memory then the main purpose of cache(take less time) would come to end, as larger the cache slower would be it's processing speed.
What is called A reserved area of the immediate access memory used to increase the running speed of the computer program?
cache memory
Which is more important cache size or processor speed?
Processing speed is far more important than cache size. Cache is a small amount of memory located in, or around the processor that is used to store small amounts of information that the processor can refer to as a quick reference. There are millions of bits flowing through cache memory every time the processor works. Any more, there is a standard amount of cache memory that is in every processor. Speed is a totally different thing and almost has nothing to do with cache size. Speed is definitely more important.
Is cache a block of high speed memory?
Yes ,i think cache memory is very fast memory in conputer system.
Advantages of cache memory?
Cache memory is a fast memory which act as a buffer memory between the main memory and the processor.It helps to increase the overall speed of the system.The data which are repeatedly used during the processing of information are loaded on to the cache memory so that each time the processor don't have to access the same from the main memory.Due to this the CPU doesn't have to use the mother board's system bus for data transfer.With the help of cache memory we can reduce the problem of bottle neck of the system bus.
How fast is the l1 cache?
The L1 cache speed runs at the same speed as the CPU-central processing unit.
