Architecture of the Internet
The Internet is structured as a vast network of networks, each operating independently but interlinked through protocols. This architecture is inherently decentralized, with no single entity controlling the entire network. Instead, various types of hardware and software work together to route and manage data across different paths.
Here are the key components of the Internet’s architecture :
- Routers and Switches: These devices direct data traffic. Routers connect different networks, directing data packets based on their destination addresses. Switches connect devices within the same network, facilitating communication between them.
- Servers and Clients: The Internet operates on a client-server model. Servers host data and services, while clients (like your computer or smartphone) request these resources. This relationship is fundamental for accessing web pages, emails, and more.
- Protocols (TCP/IP): The Transmission Control Protocol (TCP) and the Internet Protocol (IP) are crucial. TCP ensures data is reliably transmitted across the network, while IP addresses allow data to find its way to the right destination.
- ISP Networks: Internet Service Providers (ISPs) manage local networks and connect them to the broader Internet. They provide the necessary infrastructure and services for users to access the internet.
- Physical Infrastructure: This includes cables (like fiber optics and copper), satellites, and cellular towers. These physical components are essential for transmitting data over long distances.
Is Internet a Distributed System?
The Internet is a global network connecting millions of computers worldwide. It enables data and information exchange across continents in seconds. This network has transformed how we live, work, and communicate. But is the Internet a distributed system? Understanding the answer to this question requires exploring its structure and functions. In this article, we will examine if the Internet shares characteristics with traditional distributed systems.
