The Internet has become an increasingly important part of everyday life for people around the world. But if you have never used the Internet before, all this new information can be a bit confusing at first.
Throughout this tutorial, we will try to answer basic questions about the Internet and how to use it. Once complete, you will have a good understanding of how the Internet works, how to connect to the Internet, and how to browse the Web.
The Internet is a global network of billions of computers and other electronic devices. With the Internet, you can access almost all information, communicate with anyone in the world, and do much more.
You can do this by interfacing your PC to the internet. This is also known as going online. When someone says a computer is online, I t’s another way of saying that it’s connected to the Internet.
How does the Internet work?
At this point, you may be wondering how the Internet works. The exact answer is quite complicated and takes time to explain.
It is important to understand that the Internet is a global network of physical cables such as copper telephone lines, TV cables and fiber optic cables. Indeed, even remote associations like Wi-Fi and 3G/4G depend on these actual links to get to the Internet.
When you visit a website, your computer sends a request to the server through these wires. The server is where your website is stored and acts like your computer’s hard drive. When the request arrives, the server retrieves the website and sends the correct data back to the computer. The amazing thing is that this all happens in just a few seconds!
There are two main concepts that underlie the way the Internet works.
Packets and protocols
In networking, packets are small segments of large messages. Each packet contains both the data and information about that data. Information about the contents of a packet is called a “header” and is placed at the beginning of the packet so that the receiving machine knows what to do with it. To understand the purpose of packet headers, consider how some consumer products come with assembly instructions.
Connecting two computers that use different hardware and may run different software is one of the main challenges that Internet authors had to solve. Just as two people who grew up in different parts of the world need to speak a common language to understand each other, they need to use communication technology that all connected computers can understand.
The History of internet:
The Internet, also known as the net or the Web, was initially developed to support advances in computing technology by linking academic computer centers. The Internet we are currently using began development with the launch of the ARPANET in the late 1960s, with the first message sent on Friday, October 29, 1969. In 1993, the Internet grew the fastest ever, and today it is accessible to everyone. in the world.
