    DIFFERENCE BETWEEN RAM AND ROM

                      The differences between RAM and ROM are as follows:

                                           RAM                                               ROM

                       It stands for Random Access Memory.              It stands for Read-only Memory.

                       It is a volatile memory.                         It is a non-volatile memory.

                       It helps the computer while it is working.       It helps the computer to start.

                       It is a high-speed memory.                       It is slower as compared to RAM.

                          1.  Computers store data using only two numbers, 0 and 1.

                          2.  Primary memory is also known as Internal memory.

                              SECONDARY MEMORY

                      Secondary memory is permanent in nature. It is used to save work for a longer

                      period of time. The CPU cannot access data directly from secondary storage; the
                      data must first be copied to the primary memory (RAM), which makes it slower.

                      However, secondary memory is essential because it is cheaper and has much larger

                      capacity than primary memory. The devices associated with secondary memory
                      are called secondary storage devices. Let us discuss the various types of secondary
                      storage devices.

                      HARD DISK

                      A Hard Disk or Hard Disk Drive (HDD) is a common storage device
                      that  uses  flat  round  magnetic  disks,  called  platters,  to  read  and
                      write data. It is fixed inside the CPU cabinet/box. When you save any

                      document or download a game, it gets stored on a hard disk. Hard
                      disks are available in various storage capacities such as 512 GB, 1 TB, 5 TB and more.
