Emergence and Evolution of Early Networks.
The inaugural computer networks comprised specialized systems like SABRE (an airline reservation system) and AUTODIN I (a defense command-and-control system), crafted in the late 1950s and early 1960s. By the early 1960s, semiconductor technology found its way into commercial products, witnessing the deployment of both conventional batch-processing and time-sharing systems across advanced companies. Time-sharing systems, a notable innovation, enabled a computer's resources to cycle rapidly among multiple users, creating an illusion of dedicated use despite simultaneous access by many. This concept laid the foundation for the idea of sharing computer resources, leading to the emergence of ARPANET.
ARPANET, established on October 29, 1969, by the Advanced Research Projects Agency (ARPA) of the U.S. Department of Defense, marked a significant milestone. As one of the earliest general-purpose computer networks, it connected time-sharing computers at government-backed research sites, predominantly universities in the United States. ARPANET swiftly became a vital infrastructure component for the U.S. computer science research community. Tools and applications, such as the simple mail transfer protocol (SMTP or e-mail) and the file transfer protocol (FTP), quickly surfaced.
To enable cost-effective interactive communications between computers, ARPANET embraced the innovative technology of packet switching. Packet switching involves breaking large messages into smaller, manageable packets that travel independently to the destination, where they are reassembled. Unlike traditional voice communications, packet switching does not necessitate a dedicated circuit between users.
While commercial packet networks emerged in the 1970s, they primarily aimed at providing efficient access to remote computers via dedicated terminals. Telenet and Tymnet were notable examples in the United States, although they did not support host-to-host communications. DARPA (formerly ARPA) played a pivotal role in supporting ground-based and satellite-based packet networks. Ground-based packet radio systems offered mobile access to computing resources, while the packet satellite network connected the U.S. with European countries.
With the advent of packet radio, the feasibility of connecting mobile terminals to computer networks became apparent. However, the formidable size and cost of time-sharing systems at the time limited mobility. Consequently, the integration of packet radio and packet satellite networks with other networks became imperative. This interconnected network landscape laid the groundwork for the evolution of computer networks, paving the way for the expansive and interconnected digital realm we experience today.
Establishment of the Internet.
The Internet originated from efforts to interconnect research networks in the United States and Europe. DARPA initiated the Internetting program, focusing on the interconnection of diverse networks using the concept of open architecture networking. This approach relied on gateways to interconnect networks with standard interfaces. A crucial milestone was the design and development of a new protocol and system architecture, achieved through collaboration between Vinton Cerf at Stanford University and DARPA.
In 1974, Cerf and his collaborator proposed the transmission control protocol (TCP), a groundbreaking development enabling different machines on global networks to route and assemble data packets. TCP, initially incorporating the Internet protocol (IP) for global addressing, laid the foundation for the TCP/IP standard. Adopted by the U.S. Department of Defense in 1980, TCP/IP's open architecture approach gained widespread endorsement.
Throughout the 1980s, various U.S. governmental bodies, including the National Science Foundation (NSF), the Department of Energy, and NASA, played significant roles in networking. While DARPA had established an initial version of the Internet, NSF collaborated to expand access to the broader scientific and academic community. The NSF funded supercomputing centers and the development of the NSFNET, a national backbone network connecting these centers.
By the late 1980s, NSFNET operated at high speeds, and NSF funded nonprofit local and regional networks to connect users. Commercial networks emerged, leading to the formation of the Commercial Internet Exchange (CIX) to facilitate transit traffic between commercial networks. In 1995, NSF decided to withdraw support for the NSFNET infrastructure, as commercial providers could meet the research community's needs.
Over time, control of the Internet transitioned from government stewardship to private-sector participation and oversight. The Internet Engineering Task Force, a group of individuals, contributed to grassroots development for Internet standards. The nonprofit Internet Society and the Internet Corporation for Assigned Names and Numbers (ICANN) played roles in maintaining standards and overseeing domain names and numbers policies. Today, the Internet operates under a loosely structured, collaborative model involving private entities and government oversight.
Commercial expansion.
The commercialization of the Internet experienced a significant upswing, driven by the emergence of commercial services and applications. Several factors contributed to this phenomenon, including the advent of personal computers and workstations in the early 1980s. The rapid progress in integrated circuit technology, coupled with a substantial decline in computer prices, played a pivotal role in fostering this development. Concurrently, the rise of Ethernet and other local area networks facilitated the connection of personal computers, contributing to the expansion of Internet capabilities.
The restructuring of AT&T in 1984 presented additional opportunities for the National Science Foundation (NSF) to explore new options for national-level digital backbone services, leading to the evolution of the NSFNET. In 1988, a groundbreaking experiment linked a commercial e-mail service (MCI Mail) to the Internet, marking the first connection to a commercial provider outside the research community. Subsequent approvals expanded access to other e-mail providers, triggering a surge in Internet traffic.
In 1993, federal legislation granted NSF the authority to open the NSFNET backbone to commercial users. This shift was a departure from the previous "acceptable use" policy, signaling a recognition that commercially supplied network services would be more cost-effective than sustaining special-purpose network services.
The same year witnessed the release of Mosaic by the University of Illinois, a pioneering web browser that simplified Internet access through its user-friendly interface. Mosaic incorporated protocols and standards from the World Wide Web (WWW), developed by Tim Berners-Lee at the European Organization for Nuclear Research (CERN). Netscape Communications Corporation, formed in 1994, further advanced the Mosaic browser for commercial use, while Microsoft Corporation introduced Internet Explorer.
By the late 1990s, the Internet landscape boasted approximately 10,000 Internet service providers (ISPs) worldwide, with consolidation becoming prevalent as smaller providers merged or were acquired by larger counterparts. Companies like America Online, Inc. (AOL) transitioned into dominant Internet service providers, with widespread global influence and millions of subscribers by the year 2000. Internet portals like AOL, Yahoo!, and Excite became advertising hubs, leveraging their substantial user base for revenue. However, the speculative nature of some Internet services, coupled with a focus on advertising, led to a burst of the dot-com bubble by 2001.
The 21st Century Internet Landscape and Future Trajectories.
Following the collapse of the Internet bubble, the concept of "Web 2.0" emerged, signifying a shift towards social networking, user-generated content, and the advent of cloud computing.
