What is the purpose of cache memory? Cache Memory: In computer science, cache memory refers to one type or use of memory. Computer memory consists of devices that store information over a period, during which the processor and other systems can refer to it. ...
Computer technology is constantly expanding. In other words, memory, hard disk space, and other such computer processing elements are increasing in size at a rapid rate. Long gone are the days of 64 KB of RAM in our personal computers; it’s typical now to see Gigabytes (GB) of RAM on ...
What is read only memory used for? Read Only Memory: In computer science, memory refers to a method of storing information. Some of this memory can only be read after it has first been written. This contrasts against other memory which can be written multiple times. Answer and Explanation:...
Cache memory is a type of super-fast RAM which is designed to make a computer or device run more efficiently. By itself, this may not be particularly useful, but cache memory plays a key role in computing when used with other parts of memory. ...
Now compare that to the same CPU with high-end DDR4-3200 CL14 memory, which has a CL access time of 8.5ns—only 34 cycles. That's better, but the CPU would still be very inefficient if it had to wait on RAM all the time. In practice, prefetching logic combined with the cache ...

If there is the data in cache, It will fetch data from cache. This time of reading data from cache (the different between the speed of cache memory and register!) will be denoted by Hit time. If the wanted memory in the related instruction does not exist in the cache memory, it ...
How do cache expiration and cache invalidation work? Cache expiration defines the time duration for which a cached item is considered valid. Cache invalidation involves removing or updating cached items when the original content changes to ensure users receive the latest information. ...
In both cases trying to come up with constant “good” hit rate is looking for trouble. Well of course you can name 100% hit rate and all data fits in memory as perfect case but that is not the answer people are looking for. First thing which needs to be understand is – cache hit...
Volatile Storage (Memory):Requires a continuous supply of electricity to store/retain data. It acts as a computer’s primary storage for temporarily storing data and handling application workloads. Examples of non-volatile storage include cache memory and random access memory (RAM). ...
