                 Storage Devices

                 Storage devices refer to the components that store data temporarily or permanently, enabling
                 the computer to perform tasks efficiently. It is essential for both processing and data storage.
                    Primary Storage Devices: Primary storage devices, also known as main or internal memory,
                    are crucial for a computer’s functionality, temporarily holding data and instructions for efficient
                    processing by the CPU. Primary memory is of two types:

                         Random Access Memory (RAM):  RAM temporarily holds data and
                      instructions while the computer is working. Since it’s volatile, all data
                      disappears  when  the computer  is turned  off, so saving your  work
                      is essential. It allows quick access to information, making tasks run
                      smoothly.
