What Role Does the Internet Play in Our Lives?
The Internet has become an integral part of our daily lives because nearly everyone has access to an Internet-enabled device. We use it for a wide range of activities, including chatting with friends, learning new things, managing our finances, watching movies, placing pizza orders, and doing our jobs.
What if I told you there’s a science to how the Internet functions? The ability to chat with a friend on the other side of the world as if you were sitting right next to each other is something that many people wonder about. When you hit the send button in your messaging app, many things happen behind the scenes that may not be immediately apparent. Here, we’ll explain the Internet’s functions in the simplest terms possible.
One of the most important things to know is that the Internet is a vast network of computers (or any other Internet-capable device), such as your smartphone.
Basics of networking
How do you connect two or more computers? In a word, yes. Ethernet cable, Wi-Fi, and Bluetooth are all viable options. Although this works well for up to five computers or other gadgets, the setup is still cumbersome. The router comes into play here.
The router’s job is to act as a go-between for various gadgets. When devices are connected to the router, the router handles messages (or information) going both ways. It ensures that a letter sent from computer A is delivered to computer B and not computer C as the default destination. It acts like a postmaster.
However, how can you use the Internet with just this device? What about Google? Using a web browser and entering “google.com” into the address bar will return an error message if all you have is a router and a smattering of devices. So, the modem is needed.
Not all modems and routers are the same, as many people believe. Internet service providers may blame this misconception, as some offer a hybrid modem router that simplifies setup. They may look alike, but they are not the same thing. The modem establishes the Internet connection, while the router controls the flow of data received by the modem. This traffic is routed to the correct device on your home network based on the device’s request.
How the Internet Works
After learning a little about networks, we’ll see how the Internet operates. LAN and Wi-Fi file transfers are the most common methods of transferring data between devices. For the most part, data is sent from a server to a client, who then receives it.
Your web browser needs files to view a website’s content are stored on a server. As a result, a server could be considered the website’s home. The server is a special kind of computer that is always connected to the Internet and listens to customer requests.
When you type “google.com” into the address bar of your browser, your computer tells the Internet, “I want to view google.com” (of course, not literally). Your computer’s request for “google.com” files (which is Google’s server) will be responded to with “I got you, buddy!” and a message. Google’s homepage would be an example of what this means. An image, a video, or whatever else you “requested” from a web server can also be the “response.”
The IP address
There is a unique IP (Internet protocol) address assigned to each device that is connected to the Internet. A server’s speech can be uniquely identified by its Internet Protocol (IP) address. To put it another way, it’s like your physical address on the Internet.
IP addresses are generated when you enter “google.com” into the address bar of your web browser. The name you use, “google.com,” was created to make it easier for us to remember the address of a web server. This is referred to as the domain name.
Imagine that you have a multi-computer network connected to the Internet at once. If your modem only has one IP address, how can the Internet send the correct webpage or message to the proper computer? Using a router is the answer.
The router assigns each device connected to the router a unique IP address. There are two types of internal IP addresses: those that can only be seen by the router and those that can only be accessed. Your modem’s IP address serves as your external IP. On the Internet, this is how your entire home network is identified. You can easily find out your external IP address using online resources. Your operating system includes tools for finding out your device’s internal IP.
Your computer sends a request to google.com, while your sister’s phone sends a request to facebook.com. This is an example of how external and internal IP works. You and your sister’s mobile phone both have internal IP addresses of 192.168.1.11 and 192.168.1.12, respectively, when the router receives these requests. When a user makes a request, these internal IP addresses will be added as a sort of “label.” To get it to the Internet, you’ll need a modem and a router. The labels help the router know where to send the requests once the response has been received.
To make this more understandable, imagine that you live in a building with other people. Your external IP address is the address of your apartment building, and your internal IP address is the number of your room. Then you place an order for a package and, like the router, include your apartment’s address and room number in your purchase request. The box has been delivered and is addressed to the apartment where you live (your external IP). As a router sees the internal IP address, the receptionist sees the apartment number and sends it to your room. Order request and package delivery were completed successfully in this manner.
