Objects and their properties: Operational Windows system- object-oriented. This means that in this O.S. there are certain objects and O.S. Able to work with them, namely create, run, copy, move, open, etc. An object is a concept, so it has no definition. An object should be understood as everything that O.S. For example, Windows objects are files, folders, drives, windows, and so on. Any object in Widows is presented visually, namely, it is provided with an icon. An icon is a visual representation of an object. When we work with icons, we work with the objects they represent. All objects have a number of properties. There are no objects without properties, just as there are no properties without objects. All objects are distinguished by their properties. The properties of each object are unique. Properties allow you to characterize an object, specify its parameters, for example, volume, size, unique name, etc.
Operating system.
Operating system (OS ) is a set of programs that ensures the holistic functioning of a computer and its devices when interacting with the user in the process of solving various problems. information tasks on the computer.
History of creation Windows
The history of Windows dates back to 1986, when the first version of the system appeared. It was a set of programs that extended the capabilities of existing operating systems for greater ease of use. The most widespread system in our country was Windows 95. Its feature was the ability to auto tuning additional computer equipment, as well as the ability to work with the Internet. Windows development does not stand still. Now the most common systems are Windows XP and Windows Vista.
General characteristics
Windows is an integrated program. Under the control of the Windows shell, not only special programs designed for operation in the Windows environment can run, but also "regular" programs. This shell provides an efficient and comfortable exchange of information between individual programs running under its control. Users are attracted to the Windows environment by the specifics of the applications implemented in this environment. In original delivery Windows package there are several applications. They perfectly illustrate the capabilities of the shell and provide some minimal service.
When Microsoft called a press conference at Comdex in November 1985 in Las Vegas, many considered the event a last chance, especially after Windows environment was not released as promised in June of that year. The press conference smoothly flowed into the presentation of a new product -
Microsoft Windows 1.0.
Windows is a ubiquitous, essentially standard multi-tasking operating system for modern IBM-compatible computers. There are two main families of it: relatively speaking, for home use (Windows versions 3.1, 3.11, 95, 98 and Millennium Edition) and for professional applications (Windows NT versions 3.5, 4.0, 2000 and XP). Systems of the first type are installed, of course, not only on home computers, but also in most institutions, firms, and institutions. NT is used when they want to create a local or global network of an enterprise or educational institution (however, here Windows NT has serious competitors) or when it is necessary to provide increased system stability, which, generally speaking, is desirable for everyone, but for professionals it is simply vital .
From the point of view of working methods, the appearance of the screen and windows, buttons and menus, the systems of both families are very similar. So if you know how to work in Windows 95, then in NT 4.0 you will not have any special problems. And if you have mastered Windows 98 and Me, then in Win 2000 you may not notice any difference at all.
No, you will notice something: the 98th and Me often freeze, give obscure crashes, after which you have to reboot, and 2k and XP. they don't do anything.
Microsoft is going to gradually transfer all home users to new technology(NT in translation - New Technology), for which, Windows 2000 systems were created, and then XP. The development of the "old technology" has been discontinued - for the Millennium 'mind is nothing
will no longer be.
The first generation systems (Windows 3.1 and 3.11, as well as NT 3.5), which were very popular in the mid-90s, have practically died out.
Name XP comes from English. experience(an experience). The name entered the practice of use as a professional version.
Some of the most notable improvements in Windows XP over Windows 2000 are:
New GUI styling, including more rounded shapes and smooth colors; as well as additional functional improvements (such as the ability to present a folder as a slideshow in Windows Explorer).
Possibility fast switching users, which allows you to temporarily interrupt the work of one user and log in as another user, while leaving the applications launched by the first user enabled.
Function "remote assistant", allowing advanced users and technicians to connect to a Windows XP computer over the network to resolve problems. At the same time, the assisting user can see the contents of the screen, conduct a conversation, and (with the permission of the remote user) take control.
Program system recovery, designed to return the system to a certain previous state (this function is an extension of a similar program included in Windows ME), as well as improving other methods of system recovery. So, when loading the last known good configuration, the previous set of drivers is also loaded, which in some cases makes it easy to restore the system in case of problems that arose as a result of installing drivers; the ability to roll back drivers, etc.
Windows Vista came out 5 years after XP.
New system supports both 32-bit and 64-bit computers (we worked with the 32-bit version), has improved mechanisms for working with mobile devices, as well as the ability to manage and maintain a large number of computers in huge companies.
Vista will be 15% faster than Windows XP to launch applications. Vista will boot up half as fast; the number of reboots performed when installing updates will also be reduced. The operating system wakes up in just 2 seconds. In addition, Microsoft estimates that migrating to a new OS will take three-quarters less time, and installing it System Administrator will spend only about
A big plus of this system is that 32-
and 64-bit versions are being developed at the same time. So users who work with more demanding applications get a 64-bit system that meets all the requirements. However, it still has a big drawback:
64-bit operating systems are still
do not have proper support from hardware manufacturers, as many of them have not yet released drivers for their hardware.
The operating system went on sale on October 22, 2009, less than three years after the release of the previous operating system, Windows Vista .
Windows 7 included both some of the developments that were excluded from Windows Vista, as well as innovations in the interface and built-in programs. Games have been removed from Windows 7 Inkball , Ultimate Extras; applications that have analogues in Windows Live ( Windows Mail , Windows Calendar etc.), technology Microsoft t agent , Windows Meeting Space; from start menu the ability to return to the classic menu and the automatic docking of the browser and email client disappeared.
Windows 7 supports folder aliases internally. For example, the Program Files folder in some localized Windows versions was translated and displayed with a translated name, but remained in English at the file system level.
New version 11 DirectX, first released as part of this operating system, has the following improvements: support for new compute shaders, multi-threaded rendering, improved tessellation, new texture compression algorithms, etc.
player Windows Media Player 12 received new interface and became truly "omnivorous", unlike its predecessor, which required a large number of codecs to play.
Advantages Windows
1 . Usability and device support .
2. Unified user interface.
3. Support for scalable fonts.
4. Multimedia support.
5 . multitasking
6. Communication tools
7. Developer Opportunities
Windows Disadvantages
The main disadvantage of Windows for users is that the described advantages of Windows are achieved at the expense of a significant increase in the load on the computer hardware.
Windows is not a one-size-fits-all solution for all users and for all occasions.
Has its negative sides and programming under Windows. The fact is that Windows forcibly forces programmers to use the Windows programming interface (API) tools - this is more
600 functions.
Windows is the most common operating system, and for most users it is the most suitable due to its simplicity, good interface, acceptable performance and huge amount application programs for it.
