A Brief History of the Internet

Introduction

This research report will present a brief history of the Internet, focusing on some of the milestones in the development of such a fundamental international computer network system. In order to convey thorough understanding each milestone will be discussed in significant detail, thus expressing an in depth study allowing one to develop a thorough comprehension of the growth, use and possible future developments of the Internet.

When it comes to technology, all we want is more. We want it faster, we want it accessible, and we want it now. It's a trend that has always existed, and will continue existing while there is pressure from the population. Since the creation of the Internet in 1969, the Internet has rapidly developed and nowadays for most the Internet is a crucial tool for daily life. The Internet has changed the way we communicate with others due to social networking sites such as Twitter. The Internet has changed the way we express ourselves with the likes of anonymous video commenting to personal online blogging. The Internet has changed the way we advertise business and sell products through the expansion of e-Commerce. The Internet has changed the way we deliver news with many current political and foreign affairs easily accessible nowadays public outrage is exacerbated, e.g. the US ‘murder’ of Osama Bin Laden (May 2011). Therefore, the Internet past, present and future is milestone in the world’s history and this report shall outline some of the most notable breakthroughs.  

1969 – ARPANET (Advanced Research Projects Agency Network)

The ARPANET became the basis for the Internet that we all use today. The Pentagon’s Advance Research Projects Agency (Arpa) had the idea for a computer network in the early 1960s, with many believing that due to the Cold War America wanted to undermine the Russians with more advanced technology. Therefore, the ARPANET was mostly funded by US Military sources in order to assist the US Defence Agency with enhancing their military technology.

ARPANET was created using a packet switching scheme and the system consisted of a number of individual computers connected by private lines. Packet switching is still the dominant basis of today’s data communications, unlike older methods of circuit switching. Previously, circuits were reserved for the duration of only one communicating session; therefore meaning it was only possible to communicate between two parties that were interconnected. However, with packet switching, a data system is able to communicate with numerous machines through the same link, as data is collected into datagrams and transmitted as ‘packets’ whenever network links are free. Hence, not only can links be shared but also each ‘packet’ can be routed independently, therefore utilizing the available link capacity, minimizing response time and increasing the robustness of communication.

On 29th October 1969 computers at the University of California, Los Angeles and Stanford connected for the first time – therefore initiating the first 2 hosts. The first message ever sent over the Arpanet was supposed to be ‘Login’ in order to take control of the over computer, however, the UCLA to Stanford link crashed on the letter ‘g’. Hence, the first ever message was actually just ‘Lo’.

By December 2 more computers were added to the network, so in 1969 4 hosts located at The University of Utah, The University of Los Angeles, The Stanford Research Centre and The University of Santa Barbara were directly connected.

Evidently ARAPANET was a highly significant event in the Internet’s history as the development of the first functioning packet switching network paved the way for future improvements. As a result, still today in 2011, the Internet is based on ARPANET’s modern (in 1969) packet switching system and ultimately ARPANET became the core of the global Internet network to come, hence ARPANET was a crucial event in the Internet’s history.

1971 – Email

 Ray Tomlinson a BBN employee devised the first electronic mail for APRANET, while trying to develop the TENEX operating system in the early 1970s, with the local email programs called SNDMSG and READMAIL. In late 1971, Tomlinson created the first APRANET email application by adding a program called CPYNET to the SNDMSG when he updated it. The new program CPYNET was capable of copying files over the network. Using this, Tomlinson was able to send the first ever email to his colleagues announcing the existence of network email and giving instructions on how to use the new program.

Tomlinson also made the notable decision to use the ‘commercial at symbol - @’ to separate the user and host names, providing the naturally meaningful notation “user@host” that is the standard email addressing today.  Tomlinson claimed he chose the @ symbol because it made sense and was not used anywhere else.

Although these early programs had simple functionality and were command line driven, they established the basic transactional model that still defines the technology today.

Similar to ARPANET, the reason why the development of email is so significant is due to its modern day status (in 2011). Ray Tomlinson’s basic invention in 1971 has advanced dramatically to what we now use in daily life. Taking into consideration daily communication, we in the 21st century would struggle to function without the use of email. Bosses contact their employees, employees contact each other and clients, friends contact friends – basically everyone uses email. No matter where you are in the world, providing you have an Internet connection, you can communicate with anyone, and it is the fact that you can have worldwide contact without extensive costs or basic face-to-face communication that makes email so important. Although some may see this is running human contact and communication, the fact is email is practically vital in today’s society (2011).

1978 – International packet switch service 

The IPSS was created in 1978 through the collaborative works of the UK General Post Office, the Western Union Company and the United States data communications network Tymnet.

The system worked by allowing users to connect to a network via a PSS (Packet Switch Stream) modem, or an X.25 PAD (Packet Assembler/Disassembler), as well as, a dedicated PSS line. Subsequently, users could then access a variety of online databases and mainframe systems.

Available 24 hours a day 7 days week, the IPSS have a selection of three different speeds ...
