Understanding the Internet
The internet is part of everyday life. We use it to communicate, shop, manage money, watch videos, find directions, complete forms, make appointments, and answer questions.
But using the internet and understanding how it works are two different things.
You don’t need to know the technical details behind the internet to use it confidently. Understanding a few basic ideas, such as the difference between the internet, Wi-Fi, websites, browsers, and search engines, can make navigating the online world much easier.
What Is the Internet?
The internet is a worldwide network that allows computers, smartphones, tablets, and other devices to communicate with one another.
When your device connects to the internet, it can access information and services stored on computers around the world.
The internet allows you to:
- Visit websites
- Send and receive email
- Stream movies and music
- Make video calls
- Use social media
- Shop online
- Access banking services
- Get directions
- Store and share files
- Use online services and apps
Think of the internet as the system that connects all of these different services together.
The Internet and Wi-Fi Are Not the Same Thing
These terms are often used interchangeably, but they mean different things.
Internet
The internet is the larger network your device is trying to access.
Wi-Fi
Wi-Fi is one way your device connects to that network.
For example, your home may receive internet service from an internet provider. Your router then creates a Wi-Fi network that allows your phone, computer, television, and other devices to connect wirelessly.
This is why you can sometimes be connected to Wi-Fi but still have no internet access.
Your device has connected to the router, but the router may not currently have a working connection to the internet.
What Is an Internet Service Provider?
An Internet Service Provider, often called an ISP, is a company that provides your home with internet access.
Depending on where you live, internet may be delivered through:
- Cable
- Fiber
- Phone lines
- Cellular networks
- Satellite
- Fixed wireless service
Your internet provider usually supplies or connects to equipment inside your home that allows your devices to get online.
What Is a Modem?
A modem connects your home to your internet provider.
Depending on your internet service, the modem may be a separate device or combined with your router.
You usually don’t need to interact with your modem very often.
However, knowing where it is can be helpful if your internet connection stops working.
What Is a Router?
A router allows multiple devices to share your internet connection.
Your router may connect:
- Computers
- Smartphones
- Tablets
- Smart televisions
- Printers
- Game systems
- Smart home devices
The router usually creates the Wi-Fi network you see when connecting a device.
Some internet providers combine the modem and router into one piece of equipment.
What Is a Wi-Fi Network?
A Wi-Fi network has a name.
When you open the Wi-Fi settings on your device, you may see several network names nearby.
Your home network might have a name such as:
HomeWiFi
SmithFamily
Apartment5G
The name itself doesn’t matter. What matters is knowing which network belongs to you.
Most home Wi-Fi networks should also be protected with a password.
What Is a Website?
A website is a collection of information or services available through the internet.
Websites can be used for:
- Reading news
- Shopping
- Banking
- Learning
- Entertainment
- Government services
- Making appointments
- Searching for jobs
Each website has its own address, sometimes called a web address or URL.
What Is a Web Browser?
A web browser is the program or app you use to visit websites.
Common web browsers include:
- Chrome
- Safari
- Edge
- Firefox
The browser provides the window through which you access websites.
This is different from the internet itself.
You can have an internet connection without having a browser open.
What Is a Search Engine?
A search engine helps you find information on the internet.
You enter words or questions, and the search engine provides results that may help you find what you’re looking for.
A search engine is different from a web browser.
For example, you might use a browser to open a search engine, then use the search engine to find a website.
This distinction can be confusing at first because browsers often include search directly in their address bars.
Understanding Web Addresses
Every website has an address.
You may see addresses that begin with:
https://
followed by the website’s domain name.
For example:
example.com
The domain name helps identify the website you’re visiting.
Pay attention to web addresses, especially when entering personal or financial information. Scam websites sometimes use addresses that look similar to legitimate ones.
What Does HTTPS Mean?
You may notice that many website addresses begin with HTTPS.
HTTPS means the connection between your browser and the website is encrypted.
This helps protect information while it’s being transmitted.
However, HTTPS does not automatically mean a website or business is trustworthy.
Scam websites can also use HTTPS.
You should still make sure you’re visiting the correct website before entering sensitive information.
What Are Links?
A link is something you can select to move to another webpage, file, or online location.
Links may appear as:
- Words
- Buttons
- Pictures
- Menu items
Links make it easy to move around the internet.
However, links can also lead to unsafe websites.
Be cautious about clicking unexpected links in:
- Emails
- Text messages
- Pop-up windows
- Social media messages
If you’re unsure about a link, don’t rush to click it.
What Is Streaming?
Streaming allows you to watch or listen to content over the internet without downloading the entire file first.
Examples include:
- Movies
- Television shows
- Music
- Podcasts
- Live events
- Online videos
Streaming can use a significant amount of internet data, especially for high-quality video.
What Is Downloading?
Downloading means transferring something from the internet onto your device.
You might download:
- Photos
- Documents
- Apps
- Videos
- Music
- Forms
Once something is downloaded, a copy may remain on your device until you delete it.
Be careful when downloading files from unfamiliar websites.
What Is Uploading?
Uploading is the opposite of downloading.
It means sending something from your device to the internet.
For example, you’re uploading when you:
- Attach a photo to an online form
- Post a picture
- Upload a résumé
- Back up photos to cloud storage
- Submit a document online
An easy way to remember the difference:
Download = internet to your device.
Upload = your device to the internet.
What Is the Cloud?
The cloud refers to information stored on computers accessed through the internet instead of only on your own device.
Cloud services can store:
- Photos
- Documents
- Backups
- Videos
This can allow you to access the same information from multiple devices.
For example, a photo taken on your phone might also appear on your computer if both devices use the same cloud account.
What Is Cellular Data?
Smartphones and some tablets can connect to the internet without Wi-Fi by using a cellular network.
This is called cellular or mobile data.
It allows you to access the internet while you’re away from Wi-Fi.
Your phone plan may limit how much cellular data you can use each month.
Public Wi-Fi
Many places provide public Wi-Fi, including:
- Libraries
- Airports
- Hotels
- Restaurants
- Coffee shops
Public Wi-Fi can be convenient, but use extra caution when accessing sensitive accounts on networks you don’t control.
Avoid automatically connecting to unfamiliar networks simply because they’re available.
Internet Speed
Internet connections aren’t all the same speed.
Your internet speed can affect:
- How quickly websites load
- Video quality
- Video calls
- Downloads
- Online gaming
- Streaming
If several people or devices are using the same connection at once, performance may sometimes slow down.
A slow website also doesn’t necessarily mean your internet connection is the problem. The website itself could be experiencing difficulties.
When the Internet Stops Working
If you suddenly lose your internet connection, start with a few simple checks.
- See whether Wi-Fi is turned on.
- Make sure you’re connected to the correct network.
- Try another website.
- Check whether another device can connect.
- Restart the device you’re using.
- Check your modem and router.
- Restart your internet equipment if appropriate.
- Check whether your internet provider is experiencing an outage.
These steps can help determine whether the problem involves your device, Wi-Fi network, or internet service.
Basic Internet Safety
A few simple habits can make using the internet safer.
- Use strong passwords.
- Don’t share verification codes.
- Be cautious with unexpected links.
- Download files only from sources you trust.
- Check website addresses before entering sensitive information.
- Keep your devices updated.
- Don’t assume everything you read online is accurate.
- Be careful about how much personal information you share.
Online safety isn’t about being afraid of the internet. It’s about learning to recognize when something deserves a closer look.
