What Is a Url

A URL (Uniform Resource Locator) is the full web address you type or click to reach a specific page — it is the complete set of directions that tells your browser, the client from the web-browser topic, exactly where something is and how to go get it. Just as the how-the-internet-works topic showed a request traveling to a server, the URL is what specifies the destination of that request. It looks like one unbroken string, but it is really several labeled parts, each answering a different question. Take `https://www.example.com/products/shoes?color=blue`. The first part, `https://`, is the scheme (or protocol): it says which method to use — `https` for a secure web page, and the padlock the staying-safe-online topic mentioned comes precisely from that `s`. Next, `www.example.com` is the domain name, the human-friendly label that DNS, the internet's phone book from the internet topic, translates into the server's numeric address so the request knows where to go. After the domain comes the path, `/products/shoes`, which points to the specific resource on that server — much like a file path from the working-with-a-computer topic, it narrows down from the whole site to one particular page. Finally, anything after a `?` is the query string, `color=blue`, a set of extra name-and-value parameters that pass information to the page — this is how a search box sends your search terms, or how a link carries a specific filter or setting. Reading a URL from left to right therefore goes from general to specific: how to connect, which server, which page on it, and with what extra details. Understanding this structure is also a practical safety skill, tied directly to the staying-safe-online topic's warning about phishing. Because the domain is the part that truly determines which site you are really on, attackers craft deceptive URLs that look right at a glance — putting a trusted name in the path or as a subdomain while the actual domain is something else entirely, as in `https://www.yourbank.com.evil.example`, where the real domain is `evil.example`, not your bank. Knowing that the true domain sits just before the first single slash lets you spot the trick. The simple takeaway is that a URL is not a meaningless jumble but a precise, readable address: the scheme says how, the domain says which server, the path says which page, and the query passes extra details — and learning to read it, especially the domain, is both how you understand where a link goes and how you avoid being fooled about it.
