A tab on a computer is like a virtual sheet of paper within a web browser. When you open a new tab, it’s as if you’re opening another page in your internet browser, allowing you to have multiple websites open at the same time. You can easily switch between these tabs to view different web pages without closing the ones you’re not using. It’s like having several pages in a book, and you can turn to any page whenever you want. Tabs on a computer screen are like labeled sections at the top of the screen (like paper file folder tops).
