Welcome!Today we'll explore data storage and its types in IT. This is an important topic for understanding how computers store and manage information. Let's dive in!
What is Data Storage?Data storage refers to saving information in a form that computers can retrieve and use later. Modern computers use different types of storage devices to ensure data is accessible and secure.
