RAM
RAM
Data is typically processed in the central processing unit (CPU) of the computer. The CPU receives instructions and data from the computer's memory, processes them using arithmetic and logic operations, and then sends the results back to the memory for storage or further processing.
In a computer, there are many forms of media storage. We can catagorize them into 3 different categories - ROM (such as BIOS), RAM (memory), and Storage (flash drives, hard disk drives, etc.). Keep in mind that RAM retains information only when the power is on. ROM is usually stored in the BIOS chip. It basically gives your computer the most basic instructions to tell your computer to do a system check and boot your operating system. RAM is used by the computer to do just about everything. When your computer executes a program, for example, it loads the program into the RAM, interprets it, and runs it. It is generally faster than storage devices, but it cannot retain information once power is cut from it. Storage medium, as the name implies, for storing data. All data, programs, and files must be present on it for it to do anything useful.
Primary storage, called RAM memory, is temporaty one that holds data and instructions while it is processing both. And slower but more permanent is secondary storage. And those are hard drives, CD drives, DVD drives, flash drives, Zip drives and floppy drives.
Input
According to Intel: Input, Output, Processing and Storage. Input devices send data and instructions to the central processing unit. Processing executes computer instructions. Memory holds data and programs temporarily. Output devices make processed data available to the user. Storage devices store data and programs permanently.

The hard drive
The input data is processed by the CPU (Central Processing Unit) According to the set of instructions given by the user. The set of instructions is known as program.
An "Input Device".

External storage are computer hardwares that allows you to store files and other computer memorizes outside of the computer. External hard drive is a form of external storage and are generally portable.
