It has seamlessly woven into the fabric of our lives that considering it an integral part of our conscience is not wrong. Today, anyone can access the internet sitting anywhere in the world. Exactly ‘what is Internet‘ is known even by a child, but the internal details are only known by the experts. So what are you waiting for, to become familiar with every detail related to the internet, read the blog till the end.
What is Internet?
The omnipresence of the Internet is a global sensation today. Once known as a technical marvel has now become an indispensable tool for communication, information retrieval, and entertainment. The number of people who use the Internet has been increasing rapidly over the last 5 years.
The term “Internet” comprises two terms “interconnected” and “network.” The internet is like a huge worldwide club where millions of computers can talk to each other. They use special rules (protocols) to share information. The internet is like a busy city where everyone can connect, share ideas, and have fun.
How the Internet works? - Internet Service Explained
Imagine the internet as a big club where everyone can talk to each other. Now, this club has two main parts: the stuff (like your computer or phone) and the rules (which we call protocols).
- Stuff (Hardware): In the club, you have smartphones, computers, and other devices (we call them clients). There are also special computers called servers that store websites. To connect everything, we use things like cables, cell phone towers, and routers.
- Rules (Protocols): These are like the instructions for talking in the club. We use something called TCP/IP, which helps devices understand each other. Every device in the club has a unique ID called an IP address.
- Finding Websites: When you want to visit a website (like www.example.com), your device asks a DNS server (think of it like a club directory) for the website’s IP address. Once it gets it, your device can talk to the server holding the website.
- Talking in Packets: When your device talks to another, it sends information in small packets. Each packet has an ID and a destination. It is like sending tiny letters. These packets travel through the internet and reach their destination.
- Translation and Journey: The packets go through layers like floors in a building (we call it the OSI model). When they reach the server, it figures out where to send them. The server does its thing, and the website’s content comes back to your device in more packets.
- Back and Forth: The packets go back and forth until your device has all the information. It is like a conversation between your device and the server.
In the end, it is a bit like sending and receiving letters in a massive, well-organized postal system. Each device has an address and follows the rules, and voila, the internet makes it all happen!
What is an IP Address?
An IP (Internet Protocol) address is a unique numerical label assigned to each device connected to a computer network. It serves as the device’s identity on the network, allowing it to send and receive information. IP addresses help route data to the correct destination, enabling communication between devices. They come in two versions, IPv4 and IPv6, each with its specific format. IP addresses can be dynamic (changing) or static (fixed).
What are the types of Internet?
The types of Internet available for use today are as follows-
- Broadband (DSL, Cable, Fiber): Fast and reliable, broadband uses high-speed data transmission to provide internet access. DSL and cable typically use existing telephone or cable TV lines, while fiber-optic cables offer even higher speeds.
- Satellite Internet: Ideal for remote areas, satellite internet connects users via satellite signals. It can be slower than other types and may have latency issues due to the distance signals travel.
- Dial-Up: An older technology, dial-up uses phone lines to connect to the internet. It’s slow compared to broadband but may still be available in some areas.
- Mobile Internet: Accessing the internet via cellular networks, mobile internet is widely used through smartphones and mobile hotspots. Speeds vary based on network coverage and technology (3G, 4G, 5G).
- Fixed Wireless: Using radio signals, fixed wireless connects users to the internet without physical cables. It’s commonly used in areas where laying cables is challenging.
- Wi-Fi: While not a standalone type, Wi-Fi allows devices to connect to the internet wirelessly within a limited range of a router or access point. It’s commonly used in homes, businesses, and public spaces.
- Tethering: Users can share their mobile device’s internet connection with other devices through USB or Bluetooth, known as tethering.
What is a Network?
A network is a collection of computers, servers, mainframes, or other devices connected to share resources, information, or services. Networks can be categorized into different types, such as local area networks (LANs), metropolitan area networks (MANs), wide area networks (WANs), and personal area networks (PANs).
What is an Internet Protocol?
An Internet Protocol (IP) is a set of rules and conventions that govern how data is transmitted and received over a network, specifically the Internet. Each device connected to the Internet is assigned a unique IP address, which serves as its identifier. When data is sent from one device to another, IP ensures that it reaches the correct destination by routing it through the network based on these addresses. The most widely used versions are Internet Protocol version 4 (IPv4), and Internet Protocol version 6 (IPv6).
The internet protocols include-
What is the difference between the World Wide Web and the Internet?
The Internet is like a giant network that links tons of devices together, letting them share information. Now, think of the World Wide Web as a special part of the Internet—it is like a neighborhood where you can explore linked documents and stuff using web browsers.
So, the Internet is like the whole city, and the World Wide Web is one cool neighborhood in it. The Internet makes everything possible, and the World Wide Web is just one way we navigate and find things on this massive network. Not all things on the Internet are part of the World Wide Web, but the WWW relies on the Internet to exist.
What is Internet Security?
