Storage and Memory in Computers

Storage and memory are parts of the computer that are important in saving and handling information such as pictures, documents, videos and games. These parts are used to record information and execute tasks on the computer. We can divide it into points that are easy to comprehend.

What is Storage?

Storage is a process of storing information in order to be utilised in the future.

Example:

  • You could save a document in MS Word
  • Save a picture on your computer

Types of Storage Devices

Storage devices are of two types, namely primary and secondary storage.

1. Primary Storage (Temporary Storage)

The computer uses primary storage to store data required during the working time to be accessed quickly when the computer is accessed.

Storage

RAM (Random Access Memory):

  • Temporary storage.
  • Stores the data which is used by the computer at the moment.
  • Example: Suppose that you are playing a game on your computer. The data of the game is stored in RAM.
  • Note: The information is lost upon switching off.

ROM (Read Only Memory):

  • Long-term storage of valuable details.
  • Example: It contains the code that assists your computer to boot up.
  • Note: When a computer is switched off, important data is not lost.

2. Secondary Storage (Permanent Storage)

Memory

Data is permanently stored in the secondary storage even when the computer is off.

Hard Disc:

  • The main storage of a computer.
  • Stores the operating system, software and personal files.
  • Example: Saving a document or a photograph gets stored on the hard disc.

Pen Drive (USB Drive):

  • Small and portable.
  • Used to transfer files between machines.
  • Example: You can save the files on one computer using a pen drive and get them opened on another computer.

External Hard Disc:

  • Stored in a large capacity.
  • Attached to the computer via a USB.
  • Example: You can save your games, music and videos on an external hard disc.

Memory Card:

  • Applied in cameras, phones, and tablets.
  • Example: A camera has a memory card where you store photos.

Why do we require storage devices?

The value of storage devices lies in the fact that

  • They keep our data safe.
  • They assist us in file saving and re-using.
  • They used to transfer information between devices.
  • They have the capability of storing a lot of information.

What is memory?

Computer memory is a storage medium used by the computer to store data and instructions to aid the computer in its operation. Memory is of two major kinds:

  1. Primary Memory: It is temporary and is accessed fast as the computer is being used.
  2. Secondary Memory: It is permanent, and also it retains data when the computer is off.

Why is memory important?

  • Memory enables the computer to operate faster by storing data that are in use.
  • It contains files and programs required in the operation of the computer.
  • It enables us to save data to be used in the future when the computer is switched off.
