Well, as we have already studied, a computer has at least hardware and the other part of 00:00:00
our computers is software. 00:00:09
In this presentation, we are going to study the basic software. 00:00:13
The software that let us to manage all the files and other kind of hardware in the computer. 00:00:18
is usually called operating system. Software is the computer's logical support of a set of 00:00:29
logical components that makes this operation possible. But software, when you buy a software, 00:00:39
what you buy indeed is a license. So software can have different types of licenses depending 00:00:47
was the author of the software uh let you do to how let you have to to use this this kind of 00:00:55
software we can distinguish between two main licenses that are operate open source license 00:01:04
and a no commercial commercial or proprietary license so if you have an open source license 00:01:16
you can change the the software that they provide you but it isn't no open 00:01:24
open source software you are unable to change the software that they that you 00:01:34
have bought. On the other hand if it is freeware it is totally free as its name 00:01:42
show or you can have for example adware that have a lot of ads advertisement or 00:01:53
you can also have server there are different types of license our software 00:02:02
can have yeah well a software can be classified in taking into consideration 00:02:09
the function that they have in the computer so if you take into consideration this we have some 00:02:18
system applications and this system application can be firmware or operating system a firmware 00:02:27
let us to control other hardware that you have in your computer. 00:02:40
Operating system lets you to manage and control the computer in different aspects. 00:02:47
Apart from this, you can have different user applications at Office, 00:02:55
Automation, Learning, or you can have 00:03:01
some developed applications that led you to create your own software. 00:03:05
One operating system led you to control the execution of the rest of the program 00:03:14
and as an intermediary between the user and the machine. 00:03:21
So it must facilitate the communication, provide the microprocessor with the hardware resources, 00:03:26
to control the inputs and output operations, program execution, and also the different heroes that the system can have. 00:03:36
It must be comfortable, easy to use, efficiency, and obviously it has a very high evolution capacity. 00:03:47
We have some operating system which interface is graphic. 00:04:00
They are the best because the graphic interface is very intuitive, so it's very easy to use. 00:04:21
Apart from this, they can be single uses or multi-user. 00:04:30
They can also be single-task and multi-task. 00:04:37
They can also have different architectures, 32 or 64 bits. 00:04:45
Or they can be free or unaware, they can have different types of licenses. 00:04:55
Here you have a comparative chart between the most important operating system, for example, 00:05:04
the first one is the only operating system that nowadays is used using a textual interface. 00:05:11
Windows uses a graphic interface, Linux has both, graphic and textual, IOS is graphic 00:05:21
and android is graphic nowadays the most of the majority of the program the operating system 00:05:31
are graphic multi-user multitasking and they can provide the of 00:05:38
network manager. The architecture nowadays is 32, and it's a little bit obsolete, 64 and 128. If you 00:05:49
want to set up the operating system in your computer, it's necessary to organize your 00:06:13
computer using partitions. So in your hard disk you usually have a one part 00:06:21
which is MPR that let the computer to to read the hard disk but apart from this 00:06:28
when you switch on the computers you have what usually so called BIOS memory. 00:06:36
BIOS memory is a very special memory that can be switched on with a battery, 00:06:43
independent battery, and in it there are the most important software that let the 00:06:54
computer run at the beginning. One of these functions is knowing which part of 00:07:03
computer it must be reading, it must be read fast. You should configure BIOS 00:07:11
in order that create that the first device that the computer can read 00:07:22
is an external memory because it led to let computer to change for example the 00:07:29
operating system and then the second is usually the hard disk. In the hard disk you 00:07:38
usually set up the operating system so you must you must do this before using 00:07:44
any computer and it's also important if you do some backup of your computers 00:07:53
each year more or less. Well here you have the type, the size and the format of the 00:07:59
partition in which you can set up the different operating system. FAT and FAT32, well you can use 00:08:07
it but it's not very very useful because the majority of our operating system and our 00:08:19
application needs a format such as NTFS or Xtune for it is Linus or if you need 00:08:27
some partition in order to to be used as a RAM memory you can have a shape, a shape 00:08:40
partition and as you can see the format is different in this case and also the 00:08:50
size. So you must organize your hard disk before anything, with the format and with the size. 00:08:56
When you have the partitions, in each partition you are going to set up the right operating system 00:09:08
and if you have configured properly the BIOS, you can choose between different operating systems 00:09:16
because in your computer at the beginning the computer lets you to choose between for 00:09:26
example linux or windows or whatever and this is all for today i hope you you find this 00:09:33
