Memory and Storage Devices

1.   What is a computer memory?

            A physical storage space such as chips which can store information is called a                         computer memory.

2.    Types of memory:

  •  Primary Memory (Main Memory) – Works fast but stores data temporarily.
  • Secondary Memory (Storage Devices) – Stores data permanently for later use.

3.    Types of Primary Memory:

        RAM (Random Access Memory) – Temporary memory, stores data while working. 

        The data is lost when the computer is turned off.

        ROM (Read-Only Memory) – Permanent memory, stores start-up instructions. 

        We can not modify anything on it. The data stays even after the computer is off.

4.    What is a secondary memory / storage memory?

             It is used to store data permanently in a computer.

 Examples of Secondary Memory:

  • Hard Disk Drive (HDD) – Stores all files inside the computer.
  • Solid State Drive (SSD) – Faster and newer version of HDD.
  • Pen Drive (USB Flash Drive) – Small and portable storage.
  • CD/DVD (Compact Disc/Digital Versatile Disc) – Stores music, videos, and files.

5.   Name two types of storage devices.

                Internal Storage (inside the computer) and External Storage (connected from                         outside).

6.   What is the difference between memory and storage?

  •   Memory is temporary and helps the computer work faster.
  •   Storage is permanent and keeps data safe for a long time.
