00:00:01,750 --> 00:00:03,166
System architecture.

3
00:00:03,298 --> 00:00:05,854
There are two type of system architectures.

4
00:00:06,022 --> 00:00:08,994
There are 32-bit and 64-bit,

5
00:00:09,092 --> 00:00:12,970
and they are depending on your CPU,

6
00:00:13,090 --> 00:00:17,046
the chipset that is installed inside of your computer.

7
00:00:17,228 --> 00:00:19,998
The chipset comes again as a

8
00:00:20,024 --> 00:00:24,020
32-bit processor or 64-bit.

9
00:00:24,410 --> 00:00:28,398
The main difference between 32 and 64-bit is the

10
00:00:28,424 --> 00:00:32,381
one that I highlighted in this paragraph, which says a

11
00:00:32,396 --> 00:00:36,510
big difference between 32-bit processor and a 64-bit

12
00:00:36,560 --> 00:00:40,578
processor is the number of calculations per second

13
00:00:40,724 --> 00:00:43,122
they can perform. The rest,

14
00:00:43,256 --> 00:00:45,546
whatever is written, I want you to read it.

15
00:00:45,608 --> 00:00:47,622
But the primary difference is the

16
00:00:47,636 --> 00:00:50,430
one is highlighted in bold.

17
00:00:51,110 --> 00:00:54,522
So when you have a 32-bit system and

18
00:00:54,536 --> 00:00:59,766
when you have a 64-bit system, you could

19
00:00:59,888 --> 00:01:04,001
run 32-bit applications on a 64-bit system.

20
00:01:04,135 --> 00:01:07,530
However, you cannot run 64-bit

21
00:01:07,580 --> 00:01:09,980
applications on a 32-bit system.

22
00:01:10,790 --> 00:01:14,550
So when you are going and talking to

23
00:01:14,600 --> 00:01:18,502
your vendors, talking to your hardware manufacturers, you're

24
00:01:18,526 --> 00:01:21,402
going to have to decide what kind of

25
00:01:21,476 --> 00:01:24,320
architecture that you want for your computer.

26
00:01:25,490 --> 00:01:30,234
And it also depends on the user who is requesting the

27
00:01:30,272 --> 00:01:36,198
compute to have the application installed on it, what kind of

28
00:01:36,224 --> 00:01:39,954
architecture they want. In Linux, the command to find out whether

29
00:01:39,992 --> 00:01:44,334
it's a 32-bit system or 64 it's just by running

30
00:01:44,372 --> 00:01:51,594
a simple command arch, architecture. In Windows, go to My Computer,

31
00:01:51,692 --> 00:01:53,662
right click, and go to Properties.

32
00:01:53,806 --> 00:01:56,394
You should be able to see if your

33
00:01:56,432 --> 00:01:58,950
computer is 32-bit or 64-bit.

34
00:01:59,060 --> 00:02:01,878
So as an exercise for you right now at

35
00:02:01,904 --> 00:02:03,978
this point, I want you to go onto your

36
00:02:04,004 --> 00:02:07,858
Windows machine and find out what is your architecture.

37
00:02:07,954 --> 00:02:11,422
What is your CPU chipset architecture?

38
00:02:11,506 --> 00:02:13,818
Is it 32-bit or is it 64-bit?

39
00:02:13,964 --> 00:02:17,862
I bet you, most of you will find that out today.

40
00:02:18,056 --> 00:02:20,694
Let's run this command in our Linux environment and

41
00:02:20,732 --> 00:02:23,600
then we'll see how the output comes out.

42
00:02:24,110 --> 00:02:27,210
So I'll go into my Linux lab machine.

43
00:02:27,210 --> 00:02:30,030
[No audio]

44
00:02:30,030 --> 00:02:32,354
You don't have to be root to run this command.

45
00:02:32,402 --> 00:02:37,534
So I'll simply run arch, and here it would

46
00:02:37,572 --> 00:02:42,574
tell you, the last two digits is 64-bit.

47
00:02:42,732 --> 00:02:46,370
You could also get this information from another command

48
00:02:46,430 --> 00:02:50,914
that we have learned is uname -a, and

49
00:02:50,952 --> 00:02:54,600
uname -a right here, somewhere in the middle

50
00:02:54,990 --> 00:02:56,914
or close to the end, you will see the

51
00:02:56,952 --> 00:03:02,640
architecture is showing as 64-bit operating system.

52
00:03:03,330 --> 00:03:07,198
The reason I have added arch command, which

53
00:03:07,224 --> 00:03:10,378
is very short, is because sometimes you do

54
00:03:10,404 --> 00:03:13,550
have to run certain scripts in your environment,

55
00:03:13,670 --> 00:03:16,570
and you need to find out information about

56
00:03:16,620 --> 00:03:19,226
your architecture by running simple command.

57
00:03:19,358 --> 00:03:21,658
So architecture is another thing that when you

58
00:03:21,684 --> 00:03:23,614
log into any of the machine, please run

59
00:03:23,652 --> 00:03:25,790
it, try it, what are the architectures,

60
00:03:25,910 --> 00:03:29,974
and also, I would highly recommend you to go

61
00:03:30,012 --> 00:03:34,282
online, and read little more about the difference

62
00:03:34,356 --> 00:03:39,361
between 32-bit and 64-bit architecture. Thank you.
