What Is the Internet?
Understanding the Concept of the Internet
- The internet is often compared to plumbing, as it is a system that continuously moves information without users needing to understand its origins.
- Just like everyday inventions (e.g., ballpoint pen, flush toilet), most people use the internet without considering who created it or how it works.
Historical Background of the Internet
- In the early 1970s, Bob Kahn and his partner began designing what we now know as the internet, stemming from an earlier project called ARPANET.
- ARPANET was initiated by the Defense Department to create a communication system resilient enough to survive a nuclear attack, leading to innovative methods of data transmission.
Control and Structure of the Internet
- There is no single entity in charge of the internet; instead, it consists of numerous independently operated networks that collaborate for connectivity.
- The decentralized nature means decisions about routing packets and network interconnections are made independently by operators motivated by ensuring end-to-end connectivity.
Importance of Information Sharing
- The utility of the internet lies in its ability for any device to communicate with another globally, akin to making phone calls across different networks.
- Sharing information is crucial for scientific progress and innovation; this collaborative spirit drives new applications and infrastructure development on the internet.
