and memory drive to store computer data.

Let’s learn about these devices.

Storage Devices

We use storage devices to store and record a large amount of data and

information for a long time.

Hard Disk

• A hard disk looks like a box.

• It is present inside the CPU box.

• It stores a huge amount of data and information.

Pen Drive

• A pen drive is also known as a fl ash drive.

• It stores data and can be carried wherever needed.

• It is used to transfer data to another computer.

• It can store more data than a CD or DVD but less than
a hard disk.

CD and DVD

• A CD is a round shiny disk.

• It is easy to carry a CD to any place.

• A DVD also looks like a CD. It stores more data than
a CD.

Memory Card

cameras.

• The card is small in size.

• We can take this card out from devices to view data on a

computer.
