00:00:00,000 --> 00:00:09,720
If you want to work with partitions, there's a choice.

2
00:00:09,720 --> 00:00:12,920
Either you use the old way, MBR, or you go for the new way,

3
00:00:12,920 --> 00:00:14,640
which is GPT.

4
00:00:14,640 --> 00:00:16,480
Let's talk about it.

5
00:00:16,480 --> 00:00:18,360
MBR is Master Boot Record.

6
00:00:18,360 --> 00:00:20,799
It was invented in 1981.

7
00:00:20,799 --> 00:00:24,240
And it works with basic input-output system, or BIOS,

8
00:00:24,240 --> 00:00:30,080
to store partition information in a 512 bytes on-disk area,

9
00:00:30,080 --> 00:00:32,000
as well as the bootstrap loader.

10
00:00:32,000 --> 00:00:33,639
The bootstrap loader is taking care

11
00:00:33,639 --> 00:00:35,599
of loading your operating system.

12
00:00:35,599 --> 00:00:38,160
And with this bootstrap loader, there

13
00:00:38,160 --> 00:00:42,200
is 64 bytes remaining for partitions.

14
00:00:42,200 --> 00:00:45,119
And that gives you place for four primary partitions

15
00:00:45,119 --> 00:00:50,439
with a size of 16 bytes each to address metadata information

16
00:00:50,439 --> 00:00:53,119
about these partitions.

17
00:00:53,119 --> 00:00:56,520
To address more partitions, extended and logical partitions

18
00:00:56,520 --> 00:00:57,759
are needed.

19
00:00:57,759 --> 00:01:00,919
So the trick is that one of the primary partitions

20
00:01:00,919 --> 00:01:03,520
is used as an extended partition.

21
00:01:03,520 --> 00:01:05,080
And within the extended partition,

22
00:01:05,080 --> 00:01:07,800
you can create logical partitions.

23
00:01:07,800 --> 00:01:10,120
Now, in MBR, you can address a maximum

24
00:01:10,120 --> 00:01:12,320
of two tebibytes of storage.

25
00:01:12,320 --> 00:01:13,720
And that is for the simple reason

26
00:01:13,720 --> 00:01:15,680
that there is only 64 bits.

27
00:01:15,680 --> 00:01:19,040
And in 64 bits, well, addresses that can be used

28
00:01:19,040 --> 00:01:20,559
are maximized.

29
00:01:20,559 --> 00:01:22,680
Storage is limited.

30
00:01:22,680 --> 00:01:28,440
FDisk is the recommended utility to create MBR partitions.

31
00:01:28,440 --> 00:01:31,720
GWT partition table, or GPT, was developed

32
00:01:31,720 --> 00:01:34,160
to manage the shortcomings of MBR.

33
00:01:34,160 --> 00:01:36,239
It was introduced in 2010.

34
00:01:36,239 --> 00:01:38,519
And it offers larger area to store up

35
00:01:38,519 --> 00:01:42,279
to 128 partitions in total.

36
00:01:42,279 --> 00:01:45,839
Because in GPT, many partitions can be stored,

37
00:01:45,839 --> 00:01:48,680
there is no more need for extended partitions.

38
00:01:48,680 --> 00:01:51,440
And GPT is the default on systems

39
00:01:51,440 --> 00:01:54,559
that work with the Unified Extensible Firmware

40
00:01:54,559 --> 00:02:00,279
Interface, or UEFI, which is a default on all physical systems

41
00:02:00,279 --> 00:02:02,080
nowadays.

42
00:02:02,080 --> 00:02:06,720
Partet or GDisk are the tools to work with GPT partitions.

43
00:02:06,720 --> 00:02:10,479
But nowadays, FDisk has been modified

44
00:02:10,479 --> 00:02:13,679
to manage GPT partitions also.

45
00:02:13,679 --> 00:02:15,559
That depends on your distribution.

46
00:02:15,559 --> 00:02:18,119
If you're on Red Hat, you can use FDisk.

47
00:02:18,119 --> 00:02:20,919
But if I may give you a tip for your exam,

48
00:02:20,919 --> 00:02:23,600
make sure that you're also familiar with the Partet

49
00:02:23,600 --> 00:02:24,320
utility.

50
00:02:24,320 --> 00:02:27,279
There might be some questions about them.
