1
00:00:00,690 --> 00:00:09,910
Well, as we have already studied, a computer has at least hardware and the other part of

2
00:00:09,910 --> 00:00:13,070
our computers is software.

3
00:00:13,070 --> 00:00:18,649
In this presentation, we are going to study the basic software.

4
00:00:18,649 --> 00:00:29,730
The software that let us to manage all the files and other kind of hardware in the computer.

5
00:00:29,730 --> 00:00:39,579
is usually called operating system. Software is the computer's logical support of a set of

6
00:00:39,579 --> 00:00:46,539
logical components that makes this operation possible. But software, when you buy a software,

7
00:00:47,500 --> 00:00:55,979
what you buy indeed is a license. So software can have different types of licenses depending

8
00:00:55,979 --> 00:01:04,620
was the author of the software uh let you do to how let you have to to use this this kind of

9
00:01:04,620 --> 00:01:16,109
software we can distinguish between two main licenses that are operate open source license

10
00:01:16,989 --> 00:01:24,989
and a no commercial commercial or proprietary license so if you have an open source license

11
00:01:24,989 --> 00:01:34,670
you can change the the software that they provide you but it isn't no open

12
00:01:34,670 --> 00:01:42,069
open source software you are unable to change the software that they that you

13
00:01:42,069 --> 00:01:53,340
have bought. On the other hand if it is freeware it is totally free as its name

14
00:01:53,340 --> 00:02:02,379
show or you can have for example adware that have a lot of ads advertisement or

15
00:02:02,379 --> 00:02:09,939
you can also have server there are different types of license our software

16
00:02:09,939 --> 00:02:18,159
can have yeah well a software can be classified in taking into consideration

17
00:02:18,159 --> 00:02:27,639
the function that they have in the computer so if you take into consideration this we have some

18
00:02:27,639 --> 00:02:40,419
system applications and this system application can be firmware or operating system a firmware

19
00:02:40,419 --> 00:02:47,180
let us to control other hardware that you have in your computer.

20
00:02:47,180 --> 00:02:55,460
Operating system lets you to manage and control the computer in different aspects.

21
00:02:55,460 --> 00:03:01,819
Apart from this, you can have different user applications at Office,

22
00:03:01,819 --> 00:03:05,979
Automation, Learning, or you can have

23
00:03:05,979 --> 00:03:14,580
some developed applications that led you to create your own software.

24
00:03:14,580 --> 00:03:21,580
One operating system led you to control the execution of the rest of the program

25
00:03:21,580 --> 00:03:26,580
and as an intermediary between the user and the machine.

26
00:03:26,580 --> 00:03:36,580
So it must facilitate the communication, provide the microprocessor with the hardware resources,

27
00:03:36,580 --> 00:03:47,580
to control the inputs and output operations, program execution, and also the different heroes that the system can have.

28
00:03:47,580 --> 00:04:00,620
It must be comfortable, easy to use, efficiency, and obviously it has a very high evolution capacity.

29
00:04:00,620 --> 00:04:21,850
We have some operating system which interface is graphic.

30
00:04:21,850 --> 00:04:30,269
They are the best because the graphic interface is very intuitive, so it's very easy to use.

31
00:04:30,269 --> 00:04:37,949
Apart from this, they can be single uses or multi-user.

32
00:04:37,949 --> 00:04:45,290
They can also be single-task and multi-task.

33
00:04:45,290 --> 00:04:55,910
They can also have different architectures, 32 or 64 bits.

34
00:04:55,910 --> 00:05:04,120
Or they can be free or unaware, they can have different types of licenses.

35
00:05:04,120 --> 00:05:11,660
Here you have a comparative chart between the most important operating system, for example,

36
00:05:11,660 --> 00:05:21,800
the first one is the only operating system that nowadays is used using a textual interface.

37
00:05:21,800 --> 00:05:31,120
Windows uses a graphic interface, Linux has both, graphic and textual, IOS is graphic

38
00:05:31,120 --> 00:05:38,720
and android is graphic nowadays the most of the majority of the program the operating system

39
00:05:38,720 --> 00:05:49,199
are graphic multi-user multitasking and they can provide the of

40
00:05:49,199 --> 00:06:13,009
network manager. The architecture nowadays is 32, and it's a little bit obsolete, 64 and 128. If you

41
00:06:13,009 --> 00:06:21,050
want to set up the operating system in your computer, it's necessary to organize your

42
00:06:21,050 --> 00:06:28,790
computer using partitions. So in your hard disk you usually have a one part

43
00:06:28,790 --> 00:06:36,149
which is MPR that let the computer to to read the hard disk but apart from this

44
00:06:36,149 --> 00:06:43,290
when you switch on the computers you have what usually so called BIOS memory.

45
00:06:43,290 --> 00:06:54,649
BIOS memory is a very special memory that can be switched on with a battery,

46
00:06:54,649 --> 00:07:03,209
independent battery, and in it there are the most important software that let the

47
00:07:03,209 --> 00:07:11,769
computer run at the beginning. One of these functions is knowing which part of

48
00:07:11,769 --> 00:07:22,370
computer it must be reading, it must be read fast. You should configure BIOS

49
00:07:22,370 --> 00:07:29,889
in order that create that the first device that the computer can read

50
00:07:29,889 --> 00:07:38,230
is an external memory because it led to let computer to change for example the

51
00:07:38,230 --> 00:07:44,889
operating system and then the second is usually the hard disk. In the hard disk you

52
00:07:44,889 --> 00:07:53,329
usually set up the operating system so you must you must do this before using

53
00:07:53,329 --> 00:07:59,050
any computer and it's also important if you do some backup of your computers

54
00:07:59,050 --> 00:08:07,750
each year more or less. Well here you have the type, the size and the format of the

55
00:08:07,750 --> 00:08:19,670
partition in which you can set up the different operating system. FAT and FAT32, well you can use

56
00:08:19,670 --> 00:08:27,850
it but it's not very very useful because the majority of our operating system and our

57
00:08:27,850 --> 00:08:40,090
application needs a format such as NTFS or Xtune for it is Linus or if you need

58
00:08:40,090 --> 00:08:50,350
some partition in order to to be used as a RAM memory you can have a shape, a shape

59
00:08:50,350 --> 00:08:56,490
partition and as you can see the format is different in this case and also the

60
00:08:56,490 --> 00:09:05,210
size. So you must organize your hard disk before anything, with the format and with the size.

61
00:09:08,919 --> 00:09:15,320
When you have the partitions, in each partition you are going to set up the right operating system

62
00:09:16,200 --> 00:09:26,679
and if you have configured properly the BIOS, you can choose between different operating systems

63
00:09:26,679 --> 00:09:33,080
because in your computer at the beginning the computer lets you to choose between for

64
00:09:33,080 --> 00:09:44,970
example linux or windows or whatever and this is all for today i hope you you find this
