1
00:00:00,090 --> 00:00:01,140
Well, hello, my friend.
2
00:00:01,170 --> 00:00:04,050
So, guys, in this lesson, we're going to learn about servers.
3
00:00:04,620 --> 00:00:08,220
So I want to get started because, hey, what else are we going to do?
4
00:00:08,530 --> 00:00:13,350
No, I'm really excited about this stuff because they've really, really, really come a long way.
5
00:00:13,920 --> 00:00:16,320
In fact, a lot of people have servers in their houses now.
6
00:00:17,450 --> 00:00:24,320
So servers are indeed advanced, and they are durable computers, and they're actually designed to work
7
00:00:24,620 --> 00:00:30,830
uninterruptedly so that they are always accessible, protected in data centers with extensive security
8
00:00:31,160 --> 00:00:33,410
generators and cooling systems.
9
00:00:33,770 --> 00:00:38,030
And that's how we have 24-7 internet connection, by the way.
10
00:00:39,170 --> 00:00:45,050
Now, although there are many different types, the most well-known servers are Web servers, and those
11
00:00:45,050 --> 00:00:50,780
are the ones that store the content of the websites and enable the sites to be published by serving
12
00:00:50,780 --> 00:00:54,680
this content out to the internet users and internet land.
13
00:00:55,940 --> 00:01:04,130
So servers are actually digital systems where software and programs are installed and run, allowing
14
00:01:04,130 --> 00:01:06,050
multiple users to share data.
15
00:01:07,050 --> 00:01:13,770
More powerful than your average normal personal computer servers are configured to manage multiple tasks
16
00:01:13,770 --> 00:01:16,890
simultaneously and way faster.
17
00:01:18,120 --> 00:01:19,860
All right, so how does this system work then?
18
00:01:21,060 --> 00:01:28,050
Well, compared to your personal computer, servers have more memory, more multiple network connections,
19
00:01:28,500 --> 00:01:31,320
multiple hard drives and multiple CPU's.
20
00:01:31,650 --> 00:01:37,080
So for this reason, they can enable thousands or even millions of people to view the codes that create
21
00:01:37,080 --> 00:01:41,430
a web page in a very short period of time or even a short amount of time.
22
00:01:44,160 --> 00:01:45,870
So let me break it down for you a little bit more.
23
00:01:45,900 --> 00:01:48,630
A web server needs an IP address.
24
00:01:49,760 --> 00:01:53,120
That way, it will be accessed by users outside of its network.
25
00:01:54,370 --> 00:02:01,510
So each Web site also has an IP address, and this IP address is a combination of four numbers between
26
00:02:01,510 --> 00:02:03,850
zero and 255.
27
00:02:04,840 --> 00:02:13,120
And these numbers correspond to the domain name or domain address of the site, such as an example would
28
00:02:13,120 --> 00:02:19,030
be two five five Dot two one one two two Dot one two three.
29
00:02:21,200 --> 00:02:22,160
But that's just the numbers.
30
00:02:23,410 --> 00:02:24,100
Check this out.
31
00:02:24,970 --> 00:02:27,730
DNS, the domain name system.
32
00:02:28,540 --> 00:02:34,040
This is the system that connects internet users and websites with their IP addresses.
33
00:02:34,420 --> 00:02:38,140
Converts the site address typed into the address bar of a browser.
34
00:02:39,380 --> 00:02:41,480
Into the corresponding IP address.
35
00:02:42,570 --> 00:02:52,440
So it goes like this DNS and IP systems content requested by a user clicking a link, it transmits it
36
00:02:52,440 --> 00:02:55,320
from the server where it is stored to the user's computer.
37
00:02:56,040 --> 00:03:02,490
So in other words, the content of the web, such as text and images and videos, which is well, what
38
00:03:02,490 --> 00:03:07,320
the user wants to be displayed, is presented and served.
39
00:03:08,440 --> 00:03:09,820
To the visitor by the server.
40
00:03:10,300 --> 00:03:10,630
All right.
41
00:03:11,170 --> 00:03:17,230
So for this process, there is special software such as in Gen-X and Apache.
42
00:03:17,680 --> 00:03:23,560
These have to be installed on servers that will analyze the request and then display the relevant documents
43
00:03:23,560 --> 00:03:25,390
in the visitor's browser.
44
00:03:26,550 --> 00:03:27,150
Wow.
45
00:03:27,210 --> 00:03:27,870
And that's it.
46
00:03:28,950 --> 00:03:32,880
We've learned about servers now, you know, something more that you can tell your friends.
47
00:03:33,540 --> 00:03:35,400
And it gets more exciting from here.
48
00:03:35,700 --> 00:03:37,080
So I'll see you on the other side.
