Lab 04 · Intro to Computers · About 30 minutes
Search Like a Pro
Finding answers fast is one of the most valuable skills in IT. You'll learn how browsers and search engines work, then use the tricks professionals rely on to find exactly what they need, and check whether it's true. Along the way you'll complete 5 hands-on challenges, document your work, and write a professional lab report.
Your browser isn't saving progress right now (this happens in private windows and some strict browsers). The lab still works. Finish it in one sitting, or reopen it in a regular window.
Step 1
Before you begin
Locked
Same three boxes as every lab:
- HintHelp if you get stuck. Searching the web or asking an AI is encouraged; check what it tells you against your own screen.
- ChallengeHands-on work you do yourself, then capture as evidence for your lab report. Tick the box when you have it.
- Quick checkA question to make sure it clicked. Unlimited tries, and every answer explains why.
You'll need a web browser. Any search engine works for this lab; the techniques work in Google and Bing, and most work in DuckDuckGo too.
Step 2 · Lesson
How search really works
Locked
First, two words people mix up. A browser is the app you use to visit websites: Chrome, Edge, Safari, or Firefox. A search engine is a website that finds other websites: Google, Bing, or DuckDuckGo. You use a browser to reach a search engine.
A search engine works like a giant library in three steps:
| Step | Library version | What actually happens |
|---|---|---|
| Crawl | Librarians read every book | Programs called crawlers visit billions of web pages and follow their links |
| Index | The card catalog | Every word on every page is recorded so it can be found in a fraction of a second |
| Rank | The librarian's recommendation | The engine guesses which pages best answer your question and puts them first |
Two things to keep in mind: the top results aren't always the best ones. Sponsored results are ads that companies paid for, and results are tailored to your location and history, so two people can see different answers. Many search engines also show an AI-written summary at the top. It's a handy starting point, but it can be wrong, so check the sources it links to.
Quick check
Which of these is a search engine, not a browser?
Quick check
What does a Sponsored label next to a search result mean?
Quick check
You and a friend search the exact same words and get different results. Why?
Step 3 · Lesson
Search like a pro
Locked
Most people type a few words and hope. Pros give the search engine instructions using a few special symbols called operators:
| Operator | Example | What it does |
|---|---|---|
| Quotes | "printer offline" | Finds that exact phrase, in that order |
| Minus | jaguar -car | Leaves out results containing a word |
| site: | screenshot site:support.apple.com | Searches only one website |
| filetype: | budget template filetype:pdf | Finds only one kind of file |
| OR | laptop OR notebook | Finds either word (OR must be capitalized) |
You can combine them, too. Most search engines also have a Tools or date filter for showing only recent results, which matters a lot in tech, where a five-year-old answer may be wrong today.
Pro tip for troubleshooting: when a computer shows an error, search the exact error message in quotes. Someone has almost always had the same problem.
Try it
Before you move on, find out which browser you're using and which search engine it uses by default. Check your browser's settings and search for search engine.
Quick check
A computer shows the error: The printer driver is unavailable. Which search will most likely find the fix?
Quick check
You need instructions for an app, but the top results are from several years ago. What should you do?
Step 4 · Challenge
Narrow it down
Locked
Challenge 1 · Screenshot
Search for jaguar speed and look at what comes up. Then search jaguar speed -car and compare.
Take a screenshot of the second search, the one using the minus operator.
Challenge 2 · Screenshot
Use site: to find your operating system's official instructions for taking a screenshot. Search only the company's support site, such as support.microsoft.com, support.apple.com, or support.google.com.
Take a screenshot of your search and its results.
Challenge 3 · Screenshot
Find a PDF guide about password safety published by a government agency. Combine operators: password tips filetype:pdf site:.gov
Take a screenshot of your results.
Step 5 · Challenge
Check the source
Locked
Finding an answer is only half the job. A pro also asks: who wrote this, when, and can I confirm it somewhere else? Official sources, like the organization itself, a government agency, or a product's own documentation, beat random forums and content farms.
Challenge 4 · Screenshot
Who invented the World Wide Web, and in what year? Find the answer on an official source: the organization where it was invented. Then confirm it on a second, independent site.
Take a screenshot of the official page showing the answer.
Quick check
What did you find?
Quick check
You search for your bank's phone number, and the top result is a sponsored ad with a phone number. What's the safest move?

Write it up
Put these images into a short lab report: what you set out to do, what you did, and what you found. Include the exact searches you typed in your Procedure section. The Start Here guide has a template and tips. Accuracy matters more than polish.
