“What is the difference?”
Good question. It’s sort of subtle. The internet browser may be something Google Chrome, Internet Explorer, Mozilla Firefox, Microsoft Edge, Safari and Opera.
The browser provides internet access. Got to have it. The type of browser is often dependent on the type of device or operating system. For example, the iPhone uses Safari as the browser.
On computers, one can change the browser as well. For example, if a computer is using Microsoft as a operating system, you can change the browser from IE to Firefox.
The search engine provides the ability to search the internet. Within a browser, (Safari, Firefox, Chrome etc) is a setting for the default search engine. Examples. Google, Yahoo, Bing, DuckDuckGo, NATE and Naver
Here’s a guy that can explain it better then I.
