Detailed explanation-1: -RAM is the type of memory where the data is stored according to the processor. This is the correct option as RAM contains the program which is to be stored.
Detailed explanation-2: -It is the working memory which is used to store data and programs on a temporary basis. The RAM is compared to short – term or volatile memory, as it stores data that is actively used while the system is on.
Detailed explanation-3: -RAM gives applications a place to store and access data on a short-term basis. It stores the information your computer is actively using so that it can be accessed quickly. The more programs your system is running, the more you’ll need.
Detailed explanation-4: -Whether it comes from permanent storage (the hard drive) or input (the keyboard), most data goes in random access memory (RAM) first. The CPU then stores pieces of data it will need to access, often in a cache, and maintains certain special instructions in the register. We’ll talk about cache and registers later.
Detailed explanation-5: -The CPU never directly accesses RAM. Modern CPUs have one or more layers of cache. The CPU’s ability to perform calculations is much faster than the RAM’s ability to feed data to the CPU.
