A browser is your window to the web. It is the app you open to look at websites, like Chrome, Firefox, Edge, Safari, or Brave.
When you type an address or click a link, your browser asks a server for the page. The server sends back the pieces, and the browser reads that code and turns it into the page you see, with text, pictures, and buttons.
A browser has helpful parts. The address bar is where you type a web address. Tabs let you keep many pages open at once. Bookmarks save your favorite pages so you can find them again.
Browsers also do quiet, important jobs. They help keep you safe with warnings and private connections, they remember a little so pages load faster, and they can run small add-ons called extensions.
One simple habit keeps your browser working well and safely: let it update itself whenever it asks.

For grown-ups
A browser is a client that fetches resources over HTTP(S) and renders HTML, CSS, and JavaScript into the page you see. Modern browsers also handle security (HTTPS, sandboxing, warnings), caching for speed, storage like cookies and local storage, and extensions. Keeping it updated is one of the easiest security wins there is.
