00:00:00,000 --> 00:00:10,800
[Intro music]

2
00:00:10,800 --> 00:00:14,880
Linux distribution. I will cover here all the

3
00:00:14,880 --> 00:00:18,209
Linux operating system and its flavors that are

4
00:00:18,239 --> 00:00:21,209
out there, the main ones and the popular ones.

5
00:00:21,209 --> 00:00:24,000
There are many, many of them, but a few of them

6
00:00:24,000 --> 00:00:28,079
that I captured here, and the first one is Red Hat.

7
00:00:28,350 --> 00:00:31,469
You probably have heard of Red Hat from many

8
00:00:31,469 --> 00:00:35,400
different sources. Red Hat is an enterprise level

9
00:00:35,400 --> 00:00:39,599
operating system that are being used by big major

10
00:00:39,599 --> 00:00:43,229
companies. They do charge for the support, they do

11
00:00:43,229 --> 00:00:47,549
provide their own customized pre configured build

12
00:00:47,580 --> 00:00:50,580
operating systems, you cannot change it, it's not

13
00:00:50,580 --> 00:00:53,459
open source, and anything goes wrong with the

14
00:00:53,459 --> 00:00:56,130
operating system, Red Hat can provide the support

15
00:00:56,130 --> 00:01:01,139
to fix it. The next one we have is Cent Operating System,

16
00:01:01,139 --> 00:01:03,180
which is CentOS. This is the operating

17
00:01:03,180 --> 00:01:06,690
system actually we will be working with in my

18
00:01:06,690 --> 00:01:10,440
course. And the good thing about learning CentOS

19
00:01:10,470 --> 00:01:14,819
is if you are planning to apply for a job on Linux

20
00:01:15,300 --> 00:01:17,849
after the course or once you gain some experience

21
00:01:17,849 --> 00:01:21,059
or whenever you are ready, you could easily find

22
00:01:21,059 --> 00:01:25,080
many jobs in Red Hat because CentOS is exactly the same

23
00:01:25,110 --> 00:01:28,349
as Red Hat. It is also managed by Red Hat. They

24
00:01:28,349 --> 00:01:30,779
don't provide support on CentOS and it's

25
00:01:30,779 --> 00:01:35,220
completely free. Then we have Fedora, this is also

26
00:01:35,220 --> 00:01:38,910
one of the popular operating system that is used

27
00:01:38,910 --> 00:01:43,919
by many companies. Again this one is free. Then we

28
00:01:43,919 --> 00:01:48,935
have SUSE. SUSE is very popular operating system and

29
00:01:49,199 --> 00:01:54,269
in terms of customization, many people uses a disk

30
00:01:54,300 --> 00:01:57,959
operating system and they change the code to give

31
00:01:57,959 --> 00:02:01,050
their proprietary appliances and their proprietary

32
00:02:01,050 --> 00:02:05,849
programs. A lot of companies like VMware also run

33
00:02:05,879 --> 00:02:10,287
a SUSE appliances in their environment. Then we

34
00:02:10,287 --> 00:02:14,880
have Debian. Debian is very popular at the PC level

35
00:02:15,449 --> 00:02:19,199
and the last one is Ubuntu. So all of these are

36
00:02:19,889 --> 00:02:23,970
major Linux distributions and Linux operating

37
00:02:23,970 --> 00:02:28,110
systems that I wanted to highlight. You will be

38
00:02:28,110 --> 00:02:33,059
hearing many of these names down the road. And our

39
00:02:33,059 --> 00:02:36,990
focus in this course is Cent Operating System,

40
00:02:36,990 --> 00:02:38,130
which is CentOS.

41
00:02:38,130 --> 00:02:39,572
