You've made it this far and you're probably asking yourself, "Andrei, 3 00:00:06,390 --> 00:00:08,290 this has been really good really informative. 4 00:00:08,310 --> 00:00:11,039 But where is the coding; I want to start building some websites." 5 00:00:11,040 --> 00:00:13,469 And I know, I know we'll get there don't worry. 6 00:00:13,470 --> 00:00:20,249 But without even realizing it you just learned some really really important fundamental skills, and something 7 00:00:20,250 --> 00:00:28,380 that will take you very very far in the career of a web developer because now you know how to improve 8 00:00:28,430 --> 00:00:30,870 website performance without a single line of code. 9 00:00:30,910 --> 00:00:34,839 And just so you know we're gonna get a little silly here. 10 00:00:34,840 --> 00:00:40,059 We're actually going to make sure that you remember these fundamental skills every time throughout these 11 00:00:40,060 --> 00:00:45,500 lessons there's going to be chunks of very important lessons and to symbolize how important they are. 12 00:00:45,550 --> 00:00:47,739 I'm going to get Jean-Claude Van Damme's help. 13 00:00:47,740 --> 00:00:49,989 So again this is an important lesson. 14 00:00:49,990 --> 00:00:53,380 This is an important fundamental, web developer concept. 15 00:00:53,390 --> 00:00:56,790 So Jean-Claude Van Damme, how important is it? 16 00:01:01,140 --> 00:01:01,520 All right. 17 00:01:01,530 --> 00:01:03,939 So as you can see a very important concept and what is it? 18 00:01:03,940 --> 00:01:09,969 Well like I said without writing a single line of code you now know how to improve a website's performance 19 00:01:09,970 --> 00:01:11,580 so let's think about this. 20 00:01:11,620 --> 00:01:13,269 There's three things. 21 00:01:13,270 --> 00:01:19,629 We send 'google.com', we talk to Google servers, and we get these files back. So just looking at this and 22 00:01:19,630 --> 00:01:27,450 looking at what you've learned so far what's one thing that would make sure that this this process would be fast? 23 00:01:27,750 --> 00:01:30,870 Let's look at the first one I'm going to give you a second to think. 24 00:01:31,020 --> 00:01:32,489 Hopefully you get it. 25 00:01:32,490 --> 00:01:35,040 The first one is location of the server. 26 00:01:35,070 --> 00:01:37,690 We saw how big the Internet backbone is. 27 00:01:37,720 --> 00:01:43,389 So if the servers are really really close to you, let's say you're in the States and the servers are 28 00:01:43,390 --> 00:01:50,199 just a couple of kilometers away that hop is going to be really really fast versus if it's all the way 29 00:01:50,200 --> 00:01:51,130 across the globe. 30 00:01:51,160 --> 00:01:53,640 So location of the server is important. 31 00:01:53,830 --> 00:01:58,809 And we'll talk about these and how big companies use these to their advantage later on. 32 00:01:58,810 --> 00:02:00,410 So that makes sense. 33 00:02:00,430 --> 00:02:01,860 Let's look at the next one. 34 00:02:02,050 --> 00:02:04,470 So the next one is how many trips. 35 00:02:04,480 --> 00:02:11,369 So hopefully, ideally we just have one trip to the Google servers and Google servers send us all the 36 00:02:11,370 --> 00:02:12,669 files that we need back. 37 00:02:12,670 --> 00:02:19,209 But as we know there's new pages there are searches so this communication with Google is back and forth, 38 00:02:19,210 --> 00:02:19,980 back and forth. 39 00:02:19,990 --> 00:02:24,680 And the less trips we have, the faster that we would be able to to get the files. 40 00:02:24,700 --> 00:02:32,469 So how many trips. And then finally size of files again if this HTML file, CSS file, or Javascript 41 00:02:32,470 --> 00:02:35,780 file is massive and it's you know 100 megabytes. 42 00:02:35,860 --> 00:02:42,039 Well that's going to be a lot slower to transfer over the Internet than it is, if it was just a couple 43 00:02:42,040 --> 00:02:43,870 of kilobytes. 44 00:02:43,940 --> 00:02:44,750 So there it is. 45 00:02:44,760 --> 00:02:51,869 These three things are something that you'll take with you and you'll realize that every time you're 46 00:02:51,870 --> 00:02:57,449 building an application or web site you're going to be thinking about these things and these are going 47 00:02:57,450 --> 00:03:03,900 to help you make sure that you have a performant, fast web site and we're going to take these with us 48 00:03:04,050 --> 00:03:07,220 as we go on throughout the course. Talk to you soon. 5029
