We need to understand 6 00:00:23,450 --> 00:00:28,649 what this whole thing of being a web developer means and what problems we're solving and what we did 7 00:00:28,650 --> 00:00:30,030 in the past and what we do today. 8 00:00:30,140 --> 00:00:36,559 So today we're going to talk about Tim Berners-Lee, the person who invented the World Wide Web in 1989 9 00:00:36,560 --> 00:00:41,479 and I have a picture of him right here and we're going to talk about him because he's the first web 10 00:00:41,480 --> 00:00:42,170 developer. 11 00:00:42,230 --> 00:00:46,829 And in order to explain that concept we need to make a distinction between the Internet 12 00:00:46,830 --> 00:00:48,130 and the World Wide Web. 13 00:00:48,150 --> 00:00:51,589 I have this website that I'll share in the links below. 14 00:00:51,590 --> 00:00:54,350 It's really really good if you kind of want to get a history lesson. 15 00:00:54,530 --> 00:01:00,880 But essentially the Internet started off with the Arpanet in 1969, basically a military project 16 00:01:00,904 --> 00:01:01,999 and was more of a test. 17 00:01:02,100 --> 00:01:09,830 It connected a few universities such as Utah, UCLA and throughout the 70s the 80s. 18 00:01:09,930 --> 00:01:17,050 It kept growing but there was one problem that they had and that was essentially for the academics. 19 00:01:17,070 --> 00:01:23,550 They needed a way to share documents and up until the World Wide Web existed the Internet was there 20 00:01:24,010 --> 00:01:30,250 but it was really really hard for computers to communicate with each other to share academic papers 21 00:01:30,460 --> 00:01:31,410 between each other. 22 00:01:31,480 --> 00:01:34,650 Most of the time each computer had their own way of doing things. 23 00:01:34,740 --> 00:01:38,379 Or you can think of this as languages so it's kind of like communicating with people from different 24 00:01:38,380 --> 00:01:41,090 countries and a language that you don't know. 25 00:01:41,290 --> 00:01:44,449 Yeah sure you can make it work but it's very very difficult. 26 00:01:44,450 --> 00:01:46,160 So that was the problem. 27 00:01:46,250 --> 00:01:53,019 And Tim Berners-Lee what he did and he was working at CERN at the time he actually created the World 28 00:01:53,020 --> 00:02:00,980 Wide Web and what the worldwide web is it's the 'www' that we see whenever we type in Google.com 29 00:02:00,990 --> 00:02:02,080 over here. 30 00:02:02,100 --> 00:02:05,899 Is essentially a common language that computers can speak. 31 00:02:05,900 --> 00:02:10,989 With the worldwide web saying hey from now on everybody if we want to communicate together if we 32 00:02:10,990 --> 00:02:18,229 want to share images or if you want to share files let's just have this agreed upon language agreed 33 00:02:18,230 --> 00:02:22,309 upon protocol in order to share these documents together. 34 00:02:22,310 --> 00:02:23,540 So that's what it is 35 00:02:23,670 --> 00:02:30,569 those servers the HTML, CSS, Javascript, the browsers all work on top of the World Wide Web so you can 36 00:02:30,570 --> 00:02:36,989 think of it as the Internet as your phone and the World Wide Web is Instagram that runs on your phone. 37 00:02:36,990 --> 00:02:39,500 So it's essentially a decentralized application. 38 00:02:39,530 --> 00:02:42,660 Now, how is Tim Berners-Lee the first web developer? 39 00:02:42,740 --> 00:02:49,519 He actually created the first browser and the first server and later on we're actually going to 40 00:02:49,520 --> 00:02:52,060 talk about what he did with the files over here as well. 41 00:02:52,070 --> 00:02:59,460 But he created the very very first server and web browser but also the first web site. 42 00:02:59,470 --> 00:03:01,280 And they actually still have a copy of it. 43 00:03:01,510 --> 00:03:07,309 This is the very first web site ever and it's from 1991. 44 00:03:07,310 --> 00:03:13,789 And this is what it looked like, and he created this ability for people to communicate and link to other 45 00:03:13,790 --> 00:03:20,359 documents, so that we have this growing knowledge base of the world. In the next lesson we're going to 46 00:03:20,360 --> 00:03:23,520 be talking about the history of these files, 47 00:03:23,670 --> 00:03:28,540 What they mean, what problem they solved, and how they came to be. I'll see you in the next one. 48 00:03:28,610 --> 00:03:29,319 Bye-bye. 5370
