Memory and Storage Devices

Welcome to the chapter on Memory and Storage Devices for Class 6. In this chapter, you will learn about different types of memory in a computer and the devices used to store data. By the end of this chapter, you will understand how computers remember and save information!

Introduction

Computers need memory and storage to work. Memory helps the computer remember things while it is working. Storage devices help save information for later use.

Types of Memory

RAM (Random Access Memory): Temporary memory. It stores data while the computer is working. Data is lost when the computer is turned off.
ROM (Read Only Memory): Permanent memory. It stores important instructions for the computer. Data is not lost when the computer is turned off.

Storage Devices

Hard Disk: Stores large amounts of data inside the computer.
CD/DVD: Round disks used to store music, videos, and files.
Pendrive (USB Drive): Small device used to carry and transfer data.
Memory Card: Used in cameras and phones to store photos and videos.
External Hard Disk: Used to store extra data outside the computer.
Cloud Storage: Stores data on the internet. Example: Google Drive, Dropbox.

Why Do We Need Storage Devices?

To save files, photos, videos, and documents.
