The Dawn of the Digital Odyssey

The 1970’s mark a pivotal period in the the history of the internet. During this decade the foundational circuitry would be laid paving the path for the internet as we know it today. Many of the major and influential players in the technology landscape, like Microsoft and Apple, also go their start in the 1970’s.

1971

In 1971 ARPANET was improved by yet another technology – email messages. A member of the BBN Company Roy Tomlinson implemented a program that allowed users to send email messages across the ARPANET distributed network. 

At the beginning, the whole program was actually a combination of two programs: 

  1. CPYNET (a file transfer software)
  2. SENDMSG (intra-machine email software)

That same year, Michael Hart started the project Gutenberg. The goal was to make various resources and works available electronically for free. The US Declaration of Independence is the first piece of information available.

Ray Tomlinson – born in 1941 in Amsterdam, New York. He was one of the pioneering computer programmers. His greatest achievement is the implementation of an email system on ARPANET. That’s what let him earn the title “inventor of email”. Tomlinson died in 2016.

Project Gutenberg – this project is the attempt to digitize essential resources and help distribute eBooks online. It’s the oldest digital library in the world and it still exists today on the internet. This is a public domain platform that provides most things for free.

1972

The email program used on ARPANET was modified by Ray Tomlinson. A new sign (@) was introduced to create a difference between local and global emails. At the same time, Larry Roberts starts writing the first ever program for managing emails. 

The program is called RD and it will ultimately let users respond, forward, file, and read emails. While all of this is happening the IMP network is slowly expanding and currently has 23 hosts and 15 nodes. ARPANET is demonstrated to the public by Robert Kahn for the first time. 

20 computers are connected at the International Computer Communication Conference. This is actually the moment when the public learned just how important packet-switching will be for the future of computing.

The first Internet Address Registry is created by Jon Postel and other scientists. This technology will later turn into IANA or Internet Assigned Numbers Authority. All of this enables IP addresses and many other essential internet functions. 

In France, Louis Pouzin is leading a team of his own towards building their own ARPANET called CYCLADES. However, even though CYCLADES was built on the same principles as ARPANET, it was only meant for internetworking.

Internet Address Registry –  Internet Address Registry or Internet Assigned Numbers Authority is an organization that tracks IP address allocation on the global level, performs root zone management for DNS, internet numbers, and other symbols related to internet protocols.

CYCLADES – one of the first research networks that used packet switching. Hosts had to deliver data independently and there wasn’t a centralized delivery service. Transport protocols were used for exchanging Datagrams.

First email management program – at first the emails at ARPANET were sent “manually”, which involved coding. That’s why Larry Roberts decided to make things easier on ARPANET and develop the first email management program that would make sending, managing, and forwarding emails easier. This program was the foundation of email as we know it today.

1973

Ethernet was invented in 1973 by Bb Metcalfe at Xerox Parc. Metcalfe was given the task of connecting a room of computers and creating a network.

At the same time, Robert Kahn and Vint Cerf started developing the most important internet protocol TCP/IP. This protocol will be the major breakthrough that would allow different networks to communicate through the same standards.

Danny Cohen implemented the “packet voice and packet video” when setting up the visual flight simulator and upgrading its functions on ARPANET. This is called the “Network Voice Protocol” and it was the first time that packet switching was used with applications running in real time.

ARPANET went international as University College of London created a successful link. The connection was established via NORSAR in Norway.

TCP/IP protocol – the Transmission Control Protocol/Internet Protocol are two essential internet communication protocols. Through this technology computers are able to communicate from far away. TCP is in charge of reassembling and collecting data packets, while IP pinpoints the destination to which the packets should go.

Network Voice Protocol – NVP was the first ever protocol for computer networks that allowed the transportation of human speech. It used a packet switch communication principle. This was the first Voice protocol for the internet. Source: Wikipedia 

1974

The SRI International’s NIC (Network Information Center) was joined by Elizabeth Feinler. This event was very important because Feinler formed a group that had a major role to play in the development of the first white and yellow-page internet servers. 

They also created the Host Naming Registry, WHOIS server, and query-based host names for the internet. Her group also created the first essential domain names for the internet including .com, .gov, .org, .edu, .net, and so on.

Robert Kahn and Vint Cerf continued their work, successfully publishing a new paper that detailed how the TCP (Transmission Control Program) would be designed. Cerf and Khan are the people who coined the term “Internet.”

That same year, ARPANET went commercial as Telenet. It was the first ever packet data switch network made by the BBN Company and Lawrence Roberts.

Top-level domain – a domain located at the top level of the Internet and Domain Name hierarchy. At first, the domain space for top-level domains was separated into three categories including multi organizations, categories, and countries. Initially, the ARPA infrastructure top-level domains were the only ones, but they developed along with the internet.

1975

The development of the connected networks that started from ARPANET was always controlled by ARPA,  but in 1975 the operational management of these networks (the internet) transferred to the Defense Communications Agency (DCA).

That same year, the first unified email platform was created. Anyone on the network could use it for drafting, forwarding, and replying to their messages. 

UCL, BBN, and Stanford ran tests through new satellite links stretching from the UK to Hawaii.
