Try to answer the question: "Which operating systems do you know?"All, of course, aware of Windows, which is the most popular.On the other, many have not heard.We also will not go into the jungle.Recall except that of the good old Macintosh, Linux systems to advanced, including Ubuntu, which sometimes comes bundled with laptops.It is necessary to clarify that the Macintosh from Apple in its present form is only installed on the devices of this brand.
General: What is the operating system OS
essence easiest to understand by presenting the library and himself in it.In a large building kept a huge amount of books.How to find the right (not the book, but the information)?This will help librarians.Similarly constructed, and the computer.Hard drive - is the object itself, filled with books that store all the information.RAM - a desk librarian.There are processed involved in the current program.But the operating system - is the librarians.They help to work with programs and a hard disk, remove the necessary information.Of course, the larger the library / hard drive, the more data it can store.The same can be said about the RAM.What it more, the programs run faster.Here I was presented a simplified model of the OS.Formally it is: An operating system is a set of programs that are designed for data processing and control devices.It should properly allocate all the resources of the system between computing processes and is the interface between devices of computer systems and applications.And now you can go back to the question of which operating system you know.
Forms OS
Whatever it was, in spite of some variety, are the two main systems - Mac OS and Windows.The first one appeared in 1984.She already had a graphical tool before all controls only on the command line.To run any program needed to ask some text command.Such a method is very uncomfortable, but it was at the beginning of the development of computer software.Everyone understands why the man is clear what an invaluable breakthrough made by Apple.At the same time it is to control the labels and icons was created a computer mouse.But remembering what operating system you know, do not forget that the biggest drawback of Mac OS - the ability to use it only for products Apple.But it is much more expensive than the competition.But the attractiveness of the system, its advantage over the other - trouble-free operation, for example, when running at the same time two hundred applications.
little about Windows XP
This operating system has a rather advanced age.It was released three service pack, and now an official service discontinued.Despite this, it still remains one of the most popular.Consider the pros and cons.The main advantages include the following.This system is the usual, familiar to most users, when working with her problems almost never happens.Until very recently studied nuance interface.For her release a lot of games and programs, which, of course, run on other operating systems, but is not so easy.Windows XP main disadvantage is that it, unlike other systems that require large resources and has so many variety of settings.No less important disadvantage is considered and that the basic software for it is paid, and the user will have to buy it or use illegal software.Although there is an alternative - free programs, which are often not very different in their capabilities.
The good 64-bit operating system.A bit of history
Not so long ago, almost all computer run a 32-bit OS.This also applies to XP and 7-ki, which appeared not long ago.They were sold with a pre-installed.And, you set it up.This is despite the fact that have been available, and 64-bit.But they were used mainly by those who run programs that require more resources.For example, people often or constantly engaged in video editing.If you do not tell the whole story, it should be noted only that the users of the system, 64-bit, was adopted with Windows 7, and it has become part of our lives.External systems are no different from one another, and you, if you are not a programmer, do not find any difference.And now tell you about the main advantages over its 32-bit.
advantages of 64-bit operating system to a 32-bit
64-bit operating system has the following advantages over its predecessor:
- significantly increase the speed of data processing.During the same time, Windows 7, with the architecture process information twice.Keep in mind that if you use the computer only for Internet access, and printing documents, you only need a 32-bit version.For modern, graphically complex games, video editing she did not like.Many new games on it even starts.
- Many programs are available, as originally optimized for 64-bit system.On it they will run faster.And thanks to the increased speed of information processing at the same time can not work one or two, and a lot of programs without braking.
- Now you can use more RAM.And do not just install it on your computer and have the appropriate returns, then there is a real increase in productivity.
We have presented the main advantages.Most importantly - a user who has a PC with a 64-bit operating system will be much less likely to face the phenomenon of podvisanie computer, and even a complete failure of that "treated" just a forced reboot.
few words about Linux
Operating System OS Linux was created by Linus Torvalds, then a student.It differs greatly from Windows and is mainly used for server and programmers.You may ask why regular users prefer not to her, but the OS from the "Microsoft"?Because they do not want to retrain, and why, if there is a favorite over the years proven "Wind".Although recently released a number of different Linux distributions, among which we can find practically identical Windows.Consider one of them - Ubuntu.In its latest version even solved the problem with internet access.Install the program Wicd, click on "Connect" and you - in the network, configure, nothing more is needed.And the Internet is very important for Ubuntu as an update for it out every week.
One of the latest operating system - Windows 8
If you are asked about what operating system do you know, do not forget about the innovation of "Microsoft" Windows 8. So what is it innovative?The fact that it works on plates rather than on computers.Nevertheless, the operating system is recognized as a failure product.Steve Ballmer wanted to compete with the corporation Apple, but, as they say, crossed the line.Due to the dramatic change the interface, familiar to users who have problems when they move to the new system.Despite the nice view of colorful tiles, to get used to working with such a desk is not so simple.PC market continues to slowly decline, while sales of tablets are gradually increased.Most likely, the operating system 8 step aside as Vista, its time and its place will be more worthy.Especially now that you can download and install a trial version of Windows 10.
What operating system to choose
As acknowledged by many specialists and ordinary users reviews, their choice of operating system ended the purchase of devices from Apple.But most simply can not afford it because of the high cost of the devices with the Mac OS.You can select the system Linux, but most friendly to Ubuntu users is still a "Linux" with all its shortcomings.This is especially true in cases where a person has previously worked for many years with Windows, and got used to it.It is for this simple reason, the majority of it and does not leave.Go on Ubuntu in the case if you use the computer mainly for Internet access.
