The Internet is a computer network that connects the whole world for sharing data and information. It allows users to access and share information, communicate, and interact with others across the world. The Internet supports a wide range of services, including email, social media, online banking, e-commerce, streaming media, and access to websites and information resources. It is an essential tool for modern communication, education, business, and entertainment.

We get the word “Internet“ from the term “internetwork.” An internetwork is a type of LAN (Local Area Network) and/or WAN (Wide Area Network) that connects multiple networks, or intranets. In an internetwork, hosts use IP addresses to communicate with other hosts on different LANs. The internetwork is made up of many interconnected computers located in various places.

Ancient History of the Internet: In the late 1960s, ARPANET (Advanced Research Projects Agency Network) was developed by the United States Department of Defense’s ARPA (Advanced Research Projects Agency). ARPANET was the first computer network to use packet switching to connect geographically scattered computers. It was the foundation of the Internet and marked a significant milestone in the history of computing. The first node of ARPANET was established at the University of California, Los Angeles, in 1969. Tim Berners-Lee’s invention of the World Wide Web (WWW) in 1989 revolutionized how information is accessed and shared online.

Why Internet is Called a Computer Network?

The Internet is called a computer network because it consists of a vast system of interconnected computers and servers that communicate with each other. Here’s why it’s classified as a computer network:

1. Interconnection of Devices: The Internet connects millions of computers, servers, and other devices worldwide, allowing them to share data and resources.
2. Communication Protocols: It uses standardized communication protocols, such as TCP/IP (Transmission Control Protocol/Internet Protocol), to facilitate data exchange between devices. These protocols define how data is transmitted and received over the network.
3. Network Structure: It has a hierarchical structure of networks, including local area networks (LANs), wide area networks (WANs), and autonomous systems (AS). These networks are interconnected to form the global Internet.
4. Resource Sharing: The primary purpose of it, like any computer network, is to share resources, such as files, applications, and hardware (e.g., printers, storage devices), across multiple users and devices.
5. Access to Services: It provides access to a wide range of services, including the World Wide Web, email, file transfer, and online communication, which are typical features of a computer network.
6. Infrastructure: The infrastructure of the Internet includes routers, switches, and transmission media (e.g., fiber optics, satellites) that interconnect different network segments and facilitate data routing and transmission.

In essence, the Internet is a massive, global computer network that enables computers and other devices to connect and communicate with each other, making it an integral part of modern networking.
