The web (World Wide Web) is a system of interlinked documents and resources, accessed over the internet using browsers and identified by URLs. It is one service that runs on top of the internet, not the internet itself. This explanation covers the core building blocks, what happens when a page loads, and how to tell "web" apart from "internet," "browser," and "search engine."

Web vs. internet vs. browser vs. search engine

These terms get used interchangeably, but they describe different things:

A useful analogy: the internet is the road system, the web is one type of traffic that travels on it, the browser is your car, and a search engine is a directory that tells you which roads lead where.

Email, video calls, and many mobile apps also use the internet but are not the web. Email, for instance, relies on its own protocols (like SMTP) rather than web pages.

The core building blocks of the web

URLs

A URL (Uniform Resource Locator) is the address of a resource on the web. A typical URL has parts that each do a job:

https://www.example.com/products/item?id=42

• https — the protocol (how to communicate)
• www.example.com — the domain (which server to contact)
• /products/item — the path (which resource on that server)
• ?id=42 — a query string (extra parameters)

HTTP and HTTPS

HTTP (Hypertext Transfer Protocol) is the set of rules browsers and servers use to exchange requests and responses. HTTPS is the same protocol wrapped in encryption (TLS), so the data can't be read or altered in transit. Most sites today use HTTPS, and browsers flag plain HTTP as "not secure."

Browsers

A browser turns code into the pages you see. It sends requests, receives files (HTML, CSS, JavaScript, images), and renders them into a visual layout. It also manages cookies, caching, and security warnings.

Web servers

A web server is a computer (and the software on it) that stores web content and responds to requests. When you visit a page, your browser asks a server for files, and the server sends them back.

What happens when you load a page

1. You enter a URL or click a link. The browser reads the address.
2. DNS lookup. The domain name (like example.com) is translated into an IP address so the browser knows which server to contact.
3. Connection. The browser opens a connection to that server, using HTTPS if available.
4. Request. The browser sends an HTTP request for the specific resource.
5. Response. The server returns the requested files and a status code (for example, 200 for success, 404 for not found).
6. Rendering. The browser parses HTML, applies CSS for styling, runs JavaScript for interactivity, and draws the page.
7. Follow-up requests. The page may request additional resources — images, fonts, scripts — before it's fully loaded.

If any step fails, you see an error: a DNS failure means the domain couldn't be resolved; a timeout means the server didn't respond; a 404 means the server responded but the resource wasn't there.

Where the web fits in everyday use

The web is what you're using when you:

• Open a site in a browser to read, shop, or log in
• Follow a link from an email or message
• Use a web app (a service that runs in the browser rather than as an installed program)
• Watch a video embedded on a page

It is not what you're using when you:

• Send or receive email through a mail client
• Make a phone or video call over the internet
• Use an installed mobile app that talks to its own servers

Those still depend on the internet, but they don't require a browser or web pages.

Common confusions, cleared up

• "The web is down." Usually a specific site or your connection is down, not the entire web.
• "I found it on the internet." If you found it through a browser and a URL, you found it on the web.
• "My browser is the internet." The browser is a tool for accessing the web; the internet is the underlying network.
• "A search engine is the web." A search engine is one website among many that helps you navigate the web.

Quick reference

• Web = linked documents and resources accessed via browsers over the internet.
• Internet = the global network that carries many services, including the web.
• Browser = software that requests and displays web content.
• URL = the address of a web resource.
• HTTP/HTTPS = the rules for exchanging web requests and responses; HTTPS adds encryption.
• Web server = the machine that stores and serves web content.

Understanding these distinctions makes it easier to describe problems accurately, choose the right tools, and follow technical instructions without mixing up the layers.

Britannica Online is the web version of the Encyclopaedia Britannica: a general-reference platform with fact-checked articles, biographies, videos, and images written or reviewed by named experts. It works best as a starting point for research—use it to build background and vocabulary on a topic, then follow its citations and "Further Reading" links to primary and scholarly sources. Some content is free to read; other features sit behind a Britannica Premium subscription, so expect a mix of open and gated material rather than assuming everything is either free or paid.

What Britannica Online actually contains

The site describes itself as a fact-checked online encyclopedia with hundreds of thousands of objective articles, biographies, videos, and images from experts. In practice that means several content types you can use differently:

• Encyclopedia articles — overviews of people, places, events, concepts, and disciplines.
• Biographies — profiles of notable figures, useful for quick factual grounding.
• Videos and images — media that can clarify a concept or give you a visual reference point.
• Dictionary and thesaurus entries — short definitions and word relationships, handy for pinning down terminology before you search deeper.

Because it is a general encyclopedia, its strength is breadth and reliability of overview, not depth on narrow research questions. Treat it as orientation, not as your final source.

Free access vs. Britannica Premium

Britannica mixes open pages with subscription-gated ones. The site surfaces SUBSCRIBE and Subscribe to Britannica Premium links in its navigation, login box, and page footers, which signals that a meaningful portion of the experience is tied to a paid membership.

What this means for you:

• You can generally read many articles and use basic search without paying.
• Premium membership is the mechanism the site uses to unlock additional content and features.
• The exact boundary between free and premium content isn't fixed per article, so check whether a specific page is gated before you plan your research around it.

If you hit a paywall on a page you need, note the citation and look for the same information in a library database or an open scholarly source.

How to use it for research

1. Start with search, then narrow by topic

Enter your topic in the search bar. If results are too broad, browse by subject area to see how the encyclopedia organizes the field—this often reveals sub-topics and related terms you hadn't considered. Expected result: a shortlist of relevant articles and a clearer map of the topic.

2. Read for orientation, not citation

Use the opening sections to get definitions, key dates, and the main debates. Write down unfamiliar terms and names as you go—these become your next search queries in more specialized sources.

3. Check authorship and review

Britannica articles are attributed to contributors and reviewed by editors. Look for the author byline and any listed credentials. An article with a named expert and an editorial review is a stronger background source than an unattributed page.

4. Check the update date

Reference topics change—especially science, technology, politics, and law. Find the "last updated" or publication date and judge whether the information is current enough for your question. For fast-moving fields, an older article may still be useful for history but not for current facts.

5. Follow the citations and further reading

This is the highest-value step. Britannica articles typically point to external sources. Use those references to reach primary documents, scholarly articles, and books. Your final paper should cite those deeper sources, with Britannica credited only as background.

6. Verify anything you'll rely on

Cross-check key facts against at least one independent source. Encyclopedias are reliable for consensus overviews, but a single reference work shouldn't be your only support for a contested or high-stakes claim.

Evaluating a Britannica article: quick checklist

Common pitfalls

• Citing an encyclopedia as a primary source. Use it for background, then cite the sources it points to.
• Assuming everything is free. Subscription prompts appear throughout the site, so verify access before building a plan around a specific page.
• Ignoring the date. A well-written article can still be out of date for your question.
• Stopping at the overview. The real research value is in the references, not the summary.

When Britannica is the right tool—and when it isn't

Use it when you need a reliable, citable overview, a quick biography, or a way to learn the vocabulary of an unfamiliar field before diving into databases.

Skip it when you need original data, cutting-edge findings, or deep specialist analysis. For those, go straight to scholarly databases, journals, and primary documents—using Britannica only to frame your search terms.

A battle map is a scaled, top-down map used during tabletop RPG encounters to show where characters, monsters, and terrain sit relative to each other. You use one when positioning matters — combat, chases, traps, room-by-room exploration — and skip it for purely narrative scenes. You can make one by drawing terrain in a vector editor, placing assets, then exporting for screen, print, or a virtual tabletop. DungeonFog is one tool built for exactly this workflow.

Battle map vs. world map: what's the difference

These two map types answer different questions, and mixing them up is the most common early mistake.

A battle map zooms in far enough that a single chair or pillar changes your tactics. A world map zooms out far enough that a single chair is invisible. You generally need both over a campaign, but they serve different moments at the table.

When to actually put a battle map down

Reach for a battle map when the answer to "where exactly is everyone?" changes the outcome:

• Combat — line of sight, flanking, area-of-effect spells, and movement speed all depend on position.
• Dungeon crawling — doors, corridors, and room shapes matter for exploration and ambushes.
• Chases and escapes — distance and obstacles drive the tension.
• Stealth and traps — who is standing where determines what gets triggered.

Skip the map for shopping, negotiation, travel montages, and any scene where nobody cares about exact distance. Forcing a grid onto a conversation slows the game down.

How to make a custom battle map

DungeonFog describes a three-step process: create a map, place assets, then export and play. Here's what each step involves and what to expect.

1. Draw the terrain

Start with the layout — dungeon walls, building floor plans, or overland terrain. DungeonFog uses a vector-based editor, which means shapes stay sharp when you scale or print them, rather than turning blurry like a stretched bitmap. Draw the rooms and corridors first; decoration comes later.

2. Place assets

Populate the map with props, furniture, and terrain features. DungeonFog's library lists over 3,000 assets spanning different time periods and settings, and new asset packs are released monthly as part of its premium content subscription. Search the library for the pieces that match your story rather than settling for whatever's closest.

3. Export and play

You can play with others inside DungeonFog itself, or export and print the map. Exporting is where your earlier choices pay off — a vector map holds up at print resolution, and a well-scaled grid keeps tokens aligned.

Key considerations before you commit

• Grid scale. Decide your squares-per-inch (or per-5-feet) before you draw, not after. Changing it later means redoing the layout.
• Resolution. If you plan to print, you need higher resolution than for on-screen play. Vector output helps here.
• Asset library size. A bigger library means less time hunting for the right prop — but also more browsing. Check whether the library covers your campaign's setting (fantasy, modern, horror, etc.).
• Where you'll play. On screen, printed, or inside a virtual tabletop each has different export needs.

Ways to play with your map

• On screen — display the map on a TV or monitor laid flat or mounted, and move physical minis on top.
• Printed — export at print resolution and tile the pages for a physical battle mat.
• In a virtual tabletop — play with others inside DungeonFog, or export the file for use in your VTT of choice.

The practical takeaway

If you only need a quick sketch, paper and a marker still work. If you want reusable, high-detail maps that survive printing and scaling, a vector editor with a large asset library saves real time across a campaign. DungeonFog fits that second case — free to sign up, with premium memberships and a marketplace for additional content. Check the pricing page for current tiers before committing, since asset packs and premium features sit behind that subscription.
