Computer


At the core of the computer is the central processing unit or CPU, the source of control that runs all programs and instructions. In order to function, computers use two types of memory: primary and secondary. The main storage is the primary memory, and data and programs are stored in secondary memory. However, memory is not stored in the CPU, but the CPU would only be a mess of wires without it!

Memory

Nevertheless, if you had the memory of a computer, you would have a large capacity for forgetting information! That is because most computers make use of what is called random access memory (RAM). This memory is used only when the computer is completing a task. To help you better understand this, imagine the following:

You are an expert gardener, except for one important drawback. Each day, when you leave the garden, everything that you completed that day, from planting to weeding, is erased from your memory. But you are still are woken up the next morning, and asked to garden. At this command, all memories return, and you begin toiling. When the day is done, all is forgotten again.

The garden, the tools, seeds, etc., can be thought of as the secondary memory in this analogy.

Memory and Storage

While the terms 'primary memory', 'main storage', 'primary storage', 'internal storage', 'main memory', and 'RAM' are used interchangeably, the most common term used is random access memory or RAM, which is the data that contains instructions for processing computer operations: like the hapless gardener, the memory is used only for as long as the program needing it is running. Some of the reasons that a computer only needs the memory for processing include:

The computer needs to be powered on for most programs to run; once the power is off, the memory storage is wiped out.No single program can use all the memory. Programs running simultaneously need to share memory, meaning it is split among those programs.The memory storage may not be big enough to hold the processing data, so it is released when it's done.
