The History of the Internet


To begin with we as a species. We've been trying to categorize an attain all the knowledge. We haven't to a database of sorts for a very long time right so for example in seventeen twenty. Eight ephraim champions globe maker publishes the cyclopes or a universal dictionary of arts and sciences. It is the earliest attempt to link by association all the articles in an encyclopedia or more generally all the components of human knowledge. He wrote in his preface quote this. We endeavored to attain by considering the several matters. E topics not only absolutely and independently as to what they are in themselves but also relatively or as they respect each other. So we've been thinking about like how to how to access knowledge how to obtain information and organize it in in a in a way so that more people can access it quicker classic enlightenment. Classic enlightenment am my right So in one thousand. Nine hundred belgian lawyers and bibliographer paul outlet and on revilla contain proposed a central repository for the world's knowledge organized by the universal decimal classification. It was called the mondays And it would eventually house. More than fifteen million index cards one hundred thousand files and millions of images and in nineteen thirty four outlet further advanced his vision for the radiated library in which people worldwide will place telephone calls to his quote mechanical collective brain. And we'll get back information as tv signals. So this was a theory. This is something that they thought could get off the ground then in nineteen thirty six h. g. wells first predicts what's called the world brain He wrote the whole human memory can be and probably short time. We'll be made accessible to every individual time is close at hand when any student in any part of the world will be able to sit with his projector in his own study at his or her convenience to examine any book. any document in an exact replica. Study accurate it's pretty accurate so the world brain was to be a central repository of the world's knowledge organized by complex taxonomy invented by wells. So clearly there has been a precedent for desiring this kind of thing. So the concept of data communication or transmitting data between two different places through an electromagnetic medium such as radio or an electric wire predates the introduction of the first computers right. Such communication systems were typically limited to point to point communication between two end devices. Like semaphore lines are telegraph systems and telex machines so these can be considered early precursors to this kind of communication and the telegraph in the late. Nineteenth century was the first fully digital communication system. So that's just cool trivia fact it been a deeply so up until about nineteen sixty computers were huge unwieldy and self contained. You could use them as a tool. But you couldn't necessarily make them talk to each other or transmit information across any distances using them but there were a bunch of people working towards making that happen so a man named christopher stray cheesy who became the oxford university is first professor of computation filed a patent application for time sharing in february of nineteen fifty nine in june that year. He gave a paper called time sharing enlarge fast computers at the unesco information processing conference in paris where he passed the concept onto to lick lighter of mit like lighter vice president at both derek and newman inc and they discuss a computer network in his january. Nineteen sixty paper called man computer symbiosis so a quote from that is a network of computers connected to one another by wideband communication lines which provide the functions of present day libraries together with anticipated advances in information storage. And retrieval and other symbiotic functions. So super like great reading. You know just like pull it up right. Now read it. Yeah take it to the beach. You know something really exciting. So paul baran then publishes reliable digital communications systems using unreliable network repeater nodes the first of a series of papers that proposed the designed for distributed networks using packet switching. And we'll talk about that for a second. Method used to this day to transmit information over the internet and then a little later. Donald davies the. Uk's national physical laboratory or n. P. l. independently developed the same idea. So there's a little bit of like linear here So while baron used the term message blocks for his units of communication davies. Use the term packets so i was like what the hell is packet. Switching so packet switching is essentially and i. I used the the metaphor of of charlie and the chocolate factory. Ok you know mike. Tv how said the tv you're broken up into little pieces gets reassembled on the other side. That's basically what packet switching is with. Data the pieces get sent over in smaller pieces because they can travel over greater distances being smaller and then they get reassembled on the other side so that's packet switching s perfect. I'm gonna get a lot of emails. Okay so. Jc are lick lighter so jc are lick lighter. He was known as either. Jc are like friends. Call them lick several shame. I guess it's shorter than say j. C. r. guess so or just like yourself jim anyway He became the director of the newly-established information processing techniques office. Or the ipo within the us. Defense department's advanced research projects agency or darpa. So then robert. Taylor becomes the director of the information processing techniques office. Pto in nineteen sixty six and he intended to realize lighters idea of an interconnected networking system so he proposes to his boss the arpanet so the advanced research projects agency net which is a network that would connect the different projects that arpaio was sponsoring so a way to like keep everything together and at the time each project has its own specialized terminal and unique set of user commands so in order to talk to each terminal you had to physically go to the computer terminal that only spoke to that individual one so he was like what if we just had one computer that connected to everything and that was arpanet basically bam bam so there were like great. I love this. So they awarded. Arba awarded the contract to build this network to bolt beranek and newman or bbn technologies. And they're involved in the early stages of the internet in a major way and so all mentioned them like a bunch of times so the first arpanet link was established between the university of california los angeles and the stanford research institute at twenty to thirty hours on october. Twenty ninth nineteen. Sixty-nine the first message was the word log in that's boring. I know it's super boring computer guys. I was necessary to jump. It wasn't the first text message. Merry christmas oh. I don't know maybe it was being at least that s something. Yeah or what. Does it come here. I need you. That's the one for the telephone log in. Yeah right fine. at least it's easy to remember. Yeah i message sent over. The internet is the message lock-in so sent over arpanet between the network node at ucla and a second one at sri. So leonard kline rock of ucla said at the ucla and they typed in the l. and asked sri by phone if they received it got the l. Came the voice reply. Ucla typed in the. Oh asked if they got it and received got the oh. ucla then typed in the g. And the darn system crashed boy the beginning on the second attempt. It worked fine so by the end of that year. Four host computers connected together in the initial arpanet so this was like the beginning of of the end. Basically
