The Internet: Packets, Routing & Reliability
Code.org・6 minutes read
The internet functions like a car system, with data packets navigating different paths to ensure reliable delivery through routers and TCP protocols, maintaining the integrity of transmitted information and allowing seamless operation across a wide range of devices. Interconnected networks and standardized protocols enable various online activities, such as emails, web browsing, video chats, and device communication.
Insights
- Data packets in the internet are akin to cars on different routes, ensuring reliability through transmission and reassembly.
- The Transmission Control Protocol (TCP) guarantees data delivery integrity by verifying and resending packets, enhancing internet reliability and efficiency.

Data packets ensure reliable internet transmission.
- The internet operates on a system of data packets that travel through various routes, similar to cars navigating different paths to reach a destination, ensuring reliability and fault tolerance.
- Large files, like images or songs, are broken down into smaller packets for transmission, with routers managing the flow of packets through the network to ensure smooth delivery.
- The Transmission Control Protocol (TCP) guarantees the complete delivery of data packets, like a mail service, by verifying and resending missing or incomplete packets to ensure the integrity of the transmitted information.
- The scalability of the TCP and router systems allows for seamless operation across a wide range of devices, from a few to billions, enhancing the reliability and efficiency of the internet.
- The internet's functionality relies on interconnected networks and devices following standardized protocols to facilitate the smooth transmission and reassembly of data packets, enabling various online activities like emails, web browsing, video chats, and device communication.
