Search Engine:
Think of a search engine like a really smart librarian for the internet. When you type something into the search bar, like a question or a topic you're curious about, the search engine looks through its huge collection of web pages (kind of like books in a library) to find ones that match what you're looking for. It then gives you a list of those web pages in the search results. Popular search engines include Google, Bing, and Yahoo.
Web Pages:
Web pages are like digital pages on the internet. They're created by people or companies and contain all sorts of information: text, pictures, videos, and more. When you visit a website, you're looking at one or more web pages that are connected together. Each web page has its own address, called a URL, which you type into your web browser to visit it. Websites can be about anything you can imagine, from news and recipes to games and tutorials.
