The Internet architecture is the foundational framework that enables the global network of networks to function. It is composed of various layers and protocols that work together to ensure data is transmitted efficiently and reliably across the globe.
Key Components
- TCP/IP: The core protocol suite that defines how data is sent and received over the Internet.
- DNS: The Domain Name System translates human-readable domain names into IP addresses.
- Routing: The process of directing data packets from the source to the destination.
- Protocols: A set of rules and conventions for communication between devices.
Architecture Layers
- Physical Layer: The physical components of the network, such as cables and routers.
- Data Link Layer: The layer that handles the transmission of data frames between adjacent nodes.
- Network Layer: The layer responsible for routing packets across different networks.
- Transport Layer: The layer that ensures reliable delivery of data between hosts.
- Application Layer: The layer that provides services to end-user applications.
Internet Evolution
The Internet has evolved significantly since its inception. From a small research network to a global phenomenon, the Internet has transformed the way we communicate, work, and access information.
- ARPANET: The precursor to the modern Internet, developed by the U.S. Department of Defense.
- World Wide Web: Created by Tim Berners-Lee in 1989, it revolutionized the way we access information.
- Mobile Internet: The advent of smartphones and mobile data has made the Internet accessible to billions.
