Internet
- An interconnected network of computers globally, using common standards to communicate and exchange data.
- J.C.R Licklider (MIT, 1962) envisioned a globally interconnected computer system for easy access.
- Pentagon's ARPANET (1969) was a functional network for US academic and scientific research.
- Lawrence Roberts was a key architect of ARPANET.
- Ray Tomlinson sent the first email in 1972.
- ARPANET adopted TCP/IP in 1983, enabling a significant increase in the number of hosts (nearly 30,000 in 1987).
- The World Wide Web became commercialized in 1995.
- The Federal Networking Council (NFC) defined the term "Internet" in 1989.
- Internet is logically linked by a unique address space (Internet Protocol).
- Supports communication using TCP/IP and other compatible protocols.
World Wide Web
- A collection of interconnected multimedia documents stored on the internet, accessed via a standard protocol (HTTP).
- Each electronic document is a web page.
- A collection of web pages forms a website.
Protocols
- Protocols are formal specifications defining procedures for data transmission.
- TCP/IP is a foundational protocol for managing communication between servers and clients.
- HTTP is a standard for exchanging information between browsers and web servers.
