Hence it naturally follows that the provision of information security in a general problem can be achieved only if the decision of three components interconnected issues: – the protection of being in the system information from the destabilizing impact of external and internal threats – the protection of elements of the system from the destabilizing effects of external and internal information threats – protecting the environment from the threats of information from the system. In accordance with the outlined a general scheme for information security can be represented as pokazano. Consider now the state of affairs in the study and development of the second component of information security – the protection of information. Protection of information is to use special methods and means to prevent or neutralize the negative impact of the elements in the system (human and technical complexes) information as available (generated, stored, processed and used) within the system, and coming from the external environment (protection of information systems) as well as having an adverse impact output information systems to elements of the environment (information ecology). The urgency of this part of the overall problem of information security is that information can provide such impact of the on humans and technical systems, the results of which can carry not just the negative and tragic, even disastrous. Everyone knows that thinking (and even intellectual activity) Rights to a great extent subject to external influences, and these effects may be very different character, but the result it can be very profound.
This algorithm may be needed in programs loaders, whose task is to download files from the Internet, such as software download master, or application for that process web pages. The latter Related different kinds of parsers that process and downloaders from the pages of the chosen site opredelonogo opredennomu pattern information, or similar software is the task of downloading the full site given argument. Implement this task can be in three different ways. First, using the standard components of Delphi IDE for working with the network about this method can be found in the book Foundations of Delphi. Professional approach. Second, with help functions Win32 – it is the most difficult option, but the code get the most 'fast', use it if you want to achieve the fastest possible execution and most optimal and easy option with help Delphi library functions, they are based on the Win32 API. uses URLMon; … function DLFile (Source, File: string): boolean; begin try Result: = UrlDownloadToFile (nil, PChar (Source), PChar (File), 0, nil) = 0; / / Source – a source from which the file is downloaded, or the page / / File – the path on your computer to save the downloaded file or page funnaly Result: = false; / / in case error function is not nothing sledaet and the program will exit with a message about a critical error, just nothing happens end; end; Example: procedure TForm1.Button1Click (Sender: TObject); begin DownloadFile ('', 'c: working stolsite. com.txt '); end; This alternative solution is the best if you have to use operating system functions that would have to write a lot of extra code to check peredavaymyh parameters, checking the value returned by the functions and etc. In the case of components subject to the mandatory use of forms that do not always really need and create them just because you do not know how realzovat a particular algorithm is Group.
I propose the following solution (I think 97% have read do not even know what I'll write). The solution is to reinstall the operating system as soon as it gets 'dirty'. With my solution, rearrangement of the system is maximum of five minutes. Welcome Windows XP operating system the user's account. What you need: The paper handle Windows StartUp Disk Norton Symantec Ghost (or similar software) Windows Installation Disk (the very same version that you use) First of all, I would like to say that the work will be much easier if you have a computer more than one disk (no matter how physically or Partition). If it is not, but you really want to make a partition just two – do not despair, Partition Magick splits into two without the need to wash anything. With everything listed below assume that you have a second disk or another Partition.
His version of Ghost, we set and copy the master files (ghost.exe, nothing more ought such) on another disk. Thus, take a piece of paper and a pen. And write down: All the programs that should be on a fresh installation (that is, everything that you use in your everyday life). All the most important thing you need to configure and customize (dat files to icq, configure Dial-Up, etc.) After that, erase everything from the main drive (format the view) and start installing Windows system. Set up carefully and accurately, in the way of configuring everything possible and necessary. After installation, the first thing we establish all necessary for the drivers (for example, for me it is: Graphics Card, Sound Card, TV Card, Modem, Printer drivers, Digital Camera drivers,), and then install the patches and updates (I advise to pump all the most important patches from Microsoft and put on the second diskpartition).
USB flash drive is a means of storing information based on NAND technology. Unlike floppy disks, such devices portable and recordable, as well as USB flash drives are much smaller than a floppy disk (2.5 to 6 cm) and weighing about 60 grams. Capacity USB drives from 64 MB to 64 GB. Some of these devices allow you to overwrite a million times and can store information of up to 10 years. Typically, USB flash drive connected to a computer with a USB connector, 1.1 or 2.0. In USB drives have the advantage over other portable storage media, particularly floppy disks. USB more compact, fast, and can carry more information, more reliable and strong. In addition, most computers are now available without a floppy drive.
Ports for USB, On the other hand, there are now almost any computer. Flash '>'> flash drive consists of a chip protected with plastic or rubber housing, so strong that it can carry in a pocket or a keychain. USB connector is usually protected by a cap. In order to begin work with a USB device must be connected to the USB port.
