What is the Internet?

Imagine the internet as an enormous electronic library that links together all computers and devices worldwide. It allows us to effortlessly share information like photos and videos with individuals across the globe. Similar to how a library houses books filled with knowledge, the internet consists of websites and web pages where we can discover a wide range of information while also communicating with others. Essentially, it acts as an expansive digital network that grants us access to knowledge sharing and global connections.
                   

History of the Internet

The journey of the internet is one characterized by innovation and collaboration. Initially known as ARPANET in the late 1960s, it originated as a research project for the U.S. Military aimed at connecting their computers together. As time passed, ARPANET expanded its reach to include universities before eventually becoming accessible to everyone.
Tim Berners Lee brought about the inception of the World Wide Web in 1990, transforming it into a more user friendly platform. Nowadays, the internet has become a vast network that connects countless individuals and devices worldwide, greatly influencing our lifestyles, professions and modes of communication.

How Does the Internet Work

The internet functions by connecting a vast network of computers and devices worldwide. Let me provide you with a simplified explanation of its operation;
Data Transmission; When you utilize the internet, your computer or device sends and receives digital packets that contain various types of information, such as text, images, videos or any other data you access.
Addresses and Routing; Every device connected to the internet possesses a unique address known as an IP (Internet Protocol) address. Think of it as a postal address for your device. When you request information from a website or send an email, your device’s IP address is employed to identify it. Special devices called routers manage internet traffic and assist in directing these packets of data to their intended destinations.
Protocols; To ensure the successful transmission and reception of data, diverse communication protocols are utilized. The most widely used one is TCP/IP (Transmission Control Protocol/Internet Protocol). TCP ensures that data packets arrive intact and in the correct order, while IP handles addressing and routing.
Servers and Clients; The internet operates based on a client server model.
When you open a web browser, your device (the one you’re using) asks for information from a different computer that holds the website (called a web server). This request is sent out and the server then works on it and sends back the data you wanted.
To make things easier, instead of remembering numbers like IP addresses, we use domain names (such as www.example.com) to visit websites. The Domain Name System (DNS) helps by converting these domain names into the corresponding IP addresses.
When you enter a URL in your browser, DNS servers help your device find the correct IP address associated with that domain.
Data Exchange: Once your device receives the data packets from the server, it assembles them into a usable format, such as a web page or video, and displays it on your screen.
Encryption and Security: To protect your data from being intercepted by unauthorized parties, encryption is often used. This means that data is scrambled before transmission and decrypted upon arrival, ensuring privacy and security.
Global Connectivity: The internet’s infrastructure consists of a vast network of fiber optic cables, satellite links, and other technologies. This global connectivity allows data to travel across the world quickly and efficiently.

World Wide Web

The internet, often referred to as the World Wide Web (WWW), is a network of interconnected web pages and digital content found on the internet. It allows individuals to access a wide range of information, including text, images, videos and links. This can be done through popular web browsers like Chrome, Firefox or Safari. When you visit websites, search for information online, watch YouTube videos or engage on social media platforms such as Facebook – all of these activities involve using the web. It plays a vital role in connecting people globally and making information and entertainment easily accessible.
