Characteristics of OS Windows XP.

A further continuation of the Windows line is Windows XP, it has much more functionality especially in the area of multimedia, is less prone to failure and provides faster launch of many applications. Windows XP is designed for a computer with 32-64 bit Intel processors, but can be installed on other compatible processors. Windows XP is released in 3 versions:

1.Windows XP Home Edition, designed for home use and small businesses.

2.Windows XP Professional, targeted at business applications for Windows 2000 users.

3. Windows XP 64 Bit Edition – 64 bit client axis, designed for users of special technical workstations involved in the development of technical and scientific applications, as well as the creation of special effects for movies, 3D animation, etc.

The Windows XP interface is simple, the appearance of the desktop has changed somewhat, such elements as the “My Pictures” folders (music, video, etc.) have appeared. The appearance of the desktop can be changed using the desktop options settings. The start button menu has changed. The top-level menu is automatically added to the part used. Programs. The “search assistant” section has been added to the menu, which allows you to search not only on a computer, but also on the Internet, the appearance of the taskbar has changed, a function has appeared to group tasks by application type into one button. The appearance of the control panel has changed, in this folder the objects are grouped into categories, and the necessary functions are located inside the category. An additional panel appears in the Explorer window, which contains small task windows with the most commonly used OS tools. At the heart of any OS is the principle of organizing the work of an external information storage device, the essence of which is the organized storage of logically related sets of information in the form of the so-called. files.

A file is a logically connected collection of data or programs, for which a named area is allocated in external memory.

6. 6. The concept of the file system. Features and New Functions in Windows XP .

Windows XP is designed to work with the NTFS file system. When installing it, it is proposed to format the existing partition on which the OS is installed in the NTFS file system. However, this system can support file systems such as FAT32 and FAT thanks to the built-in “Application Compatibility Mode” component.

Results:

1. Innovations in Windows XP related to the file system come down to improving the ability to protect, organize and manage files.

2. Changes in the settings of the main folders of Windows XP. Each folder contains a list with links to other folders and locations, as well as basic file and folder operations.

3.When using Windows XP, network files can be made available automatically. When you reconnect to the network, all changes made to files while working offline are updated.

4. To reduce the amount of space occupied by folders and their elements, the “Compressed ZIP folders” tool is used; you can also compress archive files and folders.

5. There are options for compressing a disk using Explorer. You can compress the root directory, all subdirectories and files on the disk. To solve production-related problems, the system provides special monitor tools, which include the task manager, system monitor, alert log. The following system management features have been added to Windows XP:

a) Automatic system recovery, providing protection against errors.

b) Replacing unpatched device drivers with a previously installed version and refusing to install if it seems incompatible to the system.

c) Diagnosis and elimination of system and network problems, allowing you to find out the current status of Internet services, get information about the computer, information about the OS, etc.

d) Remote connection to a computer to gain access to any documents and files on a remote computer.

Convenience during the operation is achieved due to the presence of a large number of wizards in Windows XP. Introduced controls that display automatically resizing images for the browser window selection.

Browsers (browsers, WEB viewers), these include software tools designed to view electronic documents made in HTML format.

Modern browsers reproduce text, graphics, music, human speech, provide listening to radio broadcasts on the Internet, watching Video conferences, e-mail services, etc.

7. Use of object-oriented programming (OOP) in the Windows OS family. Characteristics of the main objects of Windows OS .

Modern technological development of software products, including Windows OS, is based on the concept of object-oriented programming, which maintains a unified approach to data and programs. The principle of event programming assumes that an application should consist of several subroutines that are called when certain events occur, which consider any change in the system related to this application. An event in the system can be the activation of a user application, the selection of a menu item, a window resize, and so on. The application informs about the occurrence of one or another event by sending1 the corresponding message. All interactions between the application and the OS are done through message passing, and the sequence of events is usually not known in advance, so parts of the application, which are called message handlers, interact only through shared data, as in OOP. Windows applications are based on: files, folders, applications, documents.

The file system provides access to a specific file and allows you to find free space when writing a new file. You can get acquainted with the general properties of the file through the properties command of the context-sensitive menu (type, size, date and time of creation). With a file of any type, you can perform a standard set of operations and actions.

A folder is a storage of objects, it can contain files, shortcuts, etc.

A label is a link to some object or a secondary image of an object indicated by its location. The shortcut is used to speed up the launch of programs or a document.

Windows/System/Shell 32.dll.

windows/programs. exe.

An application is a set of interconnected programs for creating and modifying objects (documents), as well as for managing objects of a certain type.

A document is an object created by an application that contains information of a certain type. Unlike a program, a document cannot be launched for execution, because it’s not a program, it’s data. The document can be opened in the program in which it was created.

A window is an area of the standard view screen through which the user interacts with the program. From the point of view of the application developer, a window is an independent object, the parameters of which are stored in a special data structure, and the behavior is determined by the developers of the message. That. any Windows application consists as min of 2 parts: 1 – main program, 2 – window function.

Typical Windows windows:

1. application window

2. document window

3. dialog box (dialog box)

Explorer is a program (application) with which the user can find any file system object and perform the necessary actions with it. With File Explorer, you can launch an application, open documents, move, copy, format floppy disks, surf the Web on the Internet, and so on.

Setting up the Windows environment is carried out through the tools located in the “Control Panel” folder. (Start – Settings – Control Panel).

8. Two approaches to information processed on a computer. Brief description of the types of navigation and conclusions .

There are 2 approaches to information stored in a computer:

1. Physical (when information on a computer was considered from the point of view of storing it on disks, as well as in directories and files located in specific sectors of a particular disk).

2. Logical (when information is considered from the point of view of storing it in folders and documents on a computer)

Navigating the logical structure through the main menu of the Start button is the smartest way to navigate and is used when the desktop is closed or when there are not enough icons or folders on it.

9. Two approaches to information processed on a computer. Navigation through the physical structure.

Navigate the physical structure through “my computer”. All disk drives and the entire physical structure of the computer are represented here. With it, you can work with the control panel, so. “my computer” is used to access the physical device and configure the hardware of the computer. That. My Computer is the most convenient way to navigate to solve hardware problems.

10. Two approaches to information processed on a computer. Logical structure navigation.

Navigation through the logical structure is navigation through the main menu of the Start button, which contains items such as: programs, documents, settings, search, help, run, shutdown. Used when the desktop is closed or when there are not enough icons or folders on it.

11 . Navigating with File Explorer. Purpose and functions of Explorer: operations on files. Create an object on the desktop.

Windows Explorer performs similar functions to Norton Commander (NC) in MS DOS. The explorer window consists of 2 panels: one of them contains all the folders and Windows objects, the right panel contains files and folders, the open object on the left panel. The most powerful way to navigate is File Explorer, which allows you to search for “copying”, moving and deleting files.

Navigating using the desktop is not the most convenient way to move through folders and files, because:

1. A window of a program can be maximized on the screen, and in this case you cannot see other icons and windows.

2.on the desktop, you cannot place the icons of all folders and files that are stored on the computer, i.e. the desktop cannot be “littered”.

The easiest way to navigate is the desktop – this is working with folders, icons, windows.

12. Shortcut: purpose, functions, creation and change of the shortcut icon .

Label – (this is not a file, not a document, not a device) is a link to some object, a secondary image of this object, indicating its location. You can perform actions on the shortcut: create, delete, rename. A shortcut is used to speed up the launch of a program or document. The shortcut can be created on the printer and other PCs. When you delete a shortcut, the file associated with it is not deleted. Deleting the file does not delete the shortcut either. The shortcut icon can be changed using the icon library, if it is not available or if you need to select a different icon, you can refer to the following folders:

Windows/System: Shell32. dll. Pifmgr.dll.
