Detailed explanation-1: -The RAM is the only storage that has direct access to the central processing unit (CPU), or the brains of your computer, through what is called a bus.
Detailed explanation-2: -Primary storage. Primary storage (also known as main memory, internal memory, or prime memory), often referred to simply as memory, is the only one directly accessible to the CPU. The CPU continuously reads instructions stored there and executes them as required.
Detailed explanation-3: -The two main types of primary storage are ROM, which is non-volatile, and RAM, which is volatile . Non-volatile memory keeps its contents even when the computer is switched off.
Detailed explanation-4: -The CPU interacts directly with the primary memory to perform read/ write operations. It is of two types viz. i) Random-access memory (RAM), and ii) Read-only memory (ROM). RAM is volatile i.e. as long as the power is supplied to the computer, it retains the data in it.
Detailed explanation-5: -The CPU interacts closely with primary storage, or main memory, referring to it for both instructions and data. For this reason this part of the reading will discuss memory in the context of the central processing unit. Technically, however, memory is not part of the CPU.
