Is cache memory is main or sec memory?
cache memory is neither main memory nor second memory. DDR's are Main memory and Disk is second memory.
What is a cache?
Answer:- The Cache memory is placed between the CPU and the main memory. It is a fast speed memory and is expensive and faster than the main memory. Cache memory is used to store the frequently accessed data of main memory. The instructions that are frequently used by the CPU are stored in the cache memory. It is used to reduce the average access time for address, instructions or data, which are normally stored in the main memory. Cache memory increases the operating speed of the system. But is much costlier than main memory. From economic considerations, the capacity of the cache memory is much less as compared to main memory..
Cache memory and register memory?
Register memory are smaller in size than cache memory and registers are faster than cache..Cache memory store the frequently used data from main memory..
Is cache memory is the main memory of cmputer system?
NO...The cache is a smaller, faster memory which stores copies of the data from the most frequently used main memory locations. As long as most memory accesses are cached memory locations, the average latency of memory accesses will be closer to the cache latency than to the latency of main memory.Thus Cache memory is not main memory of computer system.--- form Wiki
Why is cache memory smaller than main memory?
because cache memory is costlier than main memory and physical size of cache memory also matters.ignoring the cost , if we use large cache memory, it will take larger physical space.so mother board won't be able to accomodate it
How do you calculate the cache miss rate in a computer system?
To calculate the cache miss rate in a computer system, you divide the number of cache misses by the total number of memory accesses. This gives you a percentage that represents how often the CPU needs to fetch data from main memory instead of the cache.
Is cache memory necessary?
The cache memory is used to store the frequently used data in the main memory in order to avoid the elapse of the seek time taken to read that data in the main memory.. So, to improve the performance of a PC, its necessary to have cache memory.
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 cache hit and cache miss?
Type your answer here... in cache memory when the CPU refer to the memory and find the word in cache it is said to be hit or produced....... if the word is not found in cache it is in main memory it counts as a miss
How is the miss penalty in cache calculated?
The miss penalty in cache is calculated by determining the time it takes to access data from the main memory when a cache miss occurs. This time includes the latency of fetching the data from the main memory and loading it into the cache. The miss penalty is the additional time required when data is not found in the cache and needs to be retrieved from the main memory.
What memory locations are the fastest in terms of access solid state drives cpu registers main memory l1 cache?
Cache
What is the function of cache memory?
Cache memory is used to hold a copy of the data from the most frequently accessed memory locations to minimise calculation time. For example, a CPU's cache will hold this data so that it doesn't have to call data from the RAM for every calculation it makes, and merely draws from its local cache.
