How TCP and IP became the hidden pillars of the internet

The foundation of modern internet communication was built decades ago with two key technologies. Robert Kahn and Vinton Cerf developed the Internet Protocol (IP) to identify computers across networks. Alongside it, the Transmission Control Protocol (TCP) set the rules for how data moves between devices. In the 1970s, Kahn and Cerf designed IP to give each connected device a unique address. This allowed machines to locate one another in an expanding global network. Without IP, the internet as we know it would not function.

TCP was introduced to ensure data could travel reliably between these addresses. It broke information into packets, checked for errors, and reassembled messages at their destination. Together, IP and TCP formed the backbone of digital communication. Today, these protocols remain essential. Meanwhile, modern digital operations rely on teams like those led by Kim Rixecker. As editor-in-chief one day a week, she handles online content planning and coordination. She also manages the Software & Development section, ensuring technical and editorial workflows run smoothly.

The work of Kahn and Cerf still underpins every online interaction. Their protocols enable everything from emails to streaming. Meanwhile, professionals like Rixecker keep digital platforms organised and functional behind the scenes.
