The internet has become an indispensable part of our lives, revolutionizing communication, commerce, and information sharing on a global scale. This “network of networks” has connected people across continents, transformed industries, and reshaped society as we know it. But how did it all begin? This blog posts delves into the fascinating history of the internet, tracing its origins from its humble beginnings to the expansive network we rely on today.
Life Before The Internet
Before the advent of the internet, life was significantly different in many aspects. Here are some key aspects of life that were impacted by the absence of the internet:
Communication: Communication relied heavily on traditional methods such as landline telephones, postal mail, and face-to-face interactions. Long-distance communication was primarily through expensive international phone calls or handwritten letters that took days or even weeks to reach their recipients.
Information Retrieval: Accessing information required physical resources like books, encyclopedias, and libraries. Research involved spending hours in libraries, sifting through countless books, journals, and microfilm. Reference materials were limited to what individuals had in their personal collections or what was available locally.
News and Media: Staying updated with current events relied on newspapers, television, and radio broadcasts. Breaking news took longer to reach the masses, and people had to rely on scheduled broadcasts rather than instant updates.
Commerce and Shopping: Shopping was primarily done in brick-and-mortar stores. Consumers relied on physical catalogs or brochures to browse and purchase products. Comparison shopping required visiting multiple stores in person, and the availability of products was limited to local or regional markets.
Entertainment and Media Consumption: Entertainment options were largely limited to television, movies, radio, and physical media like CDs, DVDs, and VHS tapes. Access to music, movies, and TV shows required purchasing or renting physical copies from stores.
Social Interaction: Socializing was primarily done face-to-face or through telephone conversations. Organizing events and gatherings required more effort, such as sending invitations by mail or making phone calls.
Professional and Academic Research: Academic and professional research involved manually searching through physical libraries, journals, and archives. Collaboration required physical meetings or mailing documents, leading to slower progress and limited access to resources and expertise.
Banking and Transactions: Financial transactions involved visiting banks in person, writing checks, and using cash for everyday purchases. Online banking, electronic transfers, and digital payment systems were nonexistent.
Travel and Navigation: Planning trips relied heavily on physical maps, guidebooks, and travel agencies. Getting directions required asking locals or referring to physical maps, which could lead to delays and difficulties in unfamiliar places.
Personal Entertainment and Hobbies: Hobbies like reading, crafting, and playing musical instruments were pursued through physical books, materials, and instruments. Joining clubs or groups with similar interests often required physical meetings or advertisements in local publications.
Overall, life before the internet was slower-paced, relied more on physical resources, and required greater effort and time for various activities. The internet has significantly transformed and accelerated the way we communicate, access information, conduct business, and engage in entertainment and social interactions.
The Birth of ARPANET
The roots of the internet can be traced back to the 1960s and the U.S. Department of Defense. Their Advanced Research Projects Agency (ARPA) sought to create a reliable system beyond a single network. The primary goal was to create a decentralized and resilient network that could withstand disruptions, such as a nuclear attack. Computer scientists including J.C.R. Licklider quickly saw the potential of such a network beyond nuclear research. In 1969, ARPANET, the precursor to the modern internet, was established. It connected four universities and allowed for the sharing of resources and research among academic institutions, and other computer networks. The development of packet switching, a method of breaking electronic data into small packets for efficient transmission, formed the foundation of this groundbreaking network.
There was also competition during the Cold War era. The Soviet Union had its own computer network called the Soviet Academic Network (SANET), which connected academic and research institutions within the country. However, SANET was a closed network limited to internal communication within the Soviet Union and was not connected to the global internet.
Al Gore, the former Vice President of the United States, is often associated with a statement that he claimed to be responsible for the invention of the internet. However, this statement is a misinterpretation of his actual words and involvement.
In the 1990s, Al Gore was indeed a strong advocate for the development and expansion of the internet. He recognized its potential and played a significant role in promoting legislation that supported its growth and accessibility.
Gore was instrumental in securing funding for the Advanced Research Projects Agency Network (ARPANET), which was an early precursor to the internet. As a senator, he sponsored the High-Performance Computing and Communication Act of 1991, also known as the “Gore Bill.” This legislation allocated funds for research and development in high-performance computing and networking, including the emerging internet.
Gore’s support for the internet continued during his time as Vice President under President Bill Clinton. He helped to promote initiatives and policies that aimed to expand public access to the internet, such as the National Information Infrastructure (NII) and the Information Superhighway.
While Al Gore did not invent or create the internet, his efforts in supporting legislation and promoting its development were influential in shaping its growth and accessibility in the United States.
The Stanford Research Institute (SRI) played a significant role in the early development of the internet. In the late 1960s and early 1970s, SRI was one of the nodes (or sites) connected to the precursor of the internet, known as the ARPANET (Advanced Research Projects Agency Network).
As part of its involvement, SRI made several important contributions to the development and advancement of the ARPANET:
- Interface Message Processor (IMP): SRI was contracted by the U.S. Department of Defense’s Advanced Research Projects Agency (ARPA, now DARPA) to design and build the IMPs. These were the early routers that connected different computers and networks in the ARPANET. SRI’s team, led by Wesley Clark, developed the first IMP, which was later installed at UCLA in 1969, making it the first node on the ARPANET.
- Network Measurement Center: SRI operated the Network Measurement Center, one of the original four Network Measurement Centers on the ARPANET. This center monitored and analyzed network performance, helping to improve the network’s efficiency and reliability.
- Network Information Center (NIC): SRI hosted and operated the Network Information Center, which served as a central repository for network-related information. It maintained the ARPANET Directory, a directory of people, organizations, and resources connected to the network.
- Network protocols: SRI researchers contributed to the development and refinement of various network protocols that became the foundation of the internet. Notably, Vint Cerf, who was a member of the SRI team, co-designed the TCP/IP protocol suite, which became the standard protocol for communication on the internet.
SRI’s involvement in the ARPANET, including its work on IMPs, operation of measurement centers and the NIC, and contributions to network protocols, played a crucial role in the early stages of the internet’s development.
The first message sent over ARPANET was transmitted on October 29, 1969. The event is commonly referred to as the birth of the internet.
At 10:30 PM on that day, a graduate student at UCLA named Charley Kline attempted to send the first message to the Stanford Research Institute (SRI). Kline typed “LOGIN” on a computer terminal at UCLA’s end, and the intention was to have the message displayed at SRI’s end. However, after typing the first two letters, the system crashed, and only the letters “LO” were transmitted.
Nonetheless, this partial message marked the first time that data was successfully transmitted between two computers over a network, demonstrating the feasibility and potential of the ARPANET. The development and growth of the network from that point onwards laid the foundation for the modern internet we know today.
Kahn and Cerf
Robert Kahn is an American electrical engineer and computer scientist who played a significant role in the development of the internet and the TCP/IP protocol suite. He is often referred to as one of the “fathers of the internet.”
In the late 1960s and early 1970s, Robert Kahn worked at the U.S. Department of Defense Advanced Research Projects Agency (ARPA, now DARPA) as a program manager. During his time at ARPA, Kahn played a crucial role in the creation of the ARPANET, the precursor to the internet.
Together with Vint Cerf, Kahn co-developed the TCP/IP protocol suite, which stands for Transmission Control Protocol/Internet Protocol. TCP/IP provides the foundational protocols for communication on the internet, ensuring reliable and efficient transmission of data across networks.
Kahn and Cerf designed TCP/IP to be an open and interoperable protocol, allowing different networks to connect and communicate with each other. This was a significant breakthrough that enabled the eventual expansion and global reach of the internet.
After his work on the TCP/IP protocol suite, Kahn co-founded the Corporation for National Research Initiatives (CNRI) in 1986, where he served as its president until 2000. At CNRI, he continued to contribute to the advancement of networking technologies and internet-related research.
Robert Kahn’s contributions to the development of the internet and the TCP/IP protocol suite have been widely recognized and have had a profound impact on the way we communicate and share information in the digital age. He has received numerous awards and honors for his work, including the National Medal of Technology and Innovation in 1997 and the Turing Award in 2004, along with Vint Cerf, for their pioneering work on the internet protocols.
