They say that the "best" in the formats and standards argim in computing that there are so many to choose from. Each author is the program argim you would like to see his source, preferably a commercial format to become the next great global standard. One area where this is especially true scope of the images of optical disks, which are great inventions and a very convenient way to work with data stored, backup and almost every other field of application of optical discs. A FEW WORDS ABOUT disk image
Although we have pictures and other optical argim discs probably all meet, it's one of the things that most take for it for granted and do not think about it too much something. It mostly is not necessary, but if you are dealing with these files will not be redundant if they briefly. Picture disk (disk image) is basically a file that contains all the data stored on the media. This means that not only contains files with the media, but also the structure of the media itself and the information about where exactly is what saved file. So the image contains information about the structure of the media "sector by sector" or "byte for byte" and is so precise contextual and structural copy of the medium. Some tools for working with disk images for such "cloning" disc content is compressed, mostly in order to remove unused space. This file is no longer figure in the literal argim sense, but already one of the archive files.
Today, the use of images of hard drives for backup area, quite separate from the scope of the images of optical disks, which are mainly used for file transfer and backup optical discs. The biggest advantage of these files is that the installation of the optical disc or download its contents somewhere else is not necessary to write ("baking") physical puck CD or DVD, but you can use their images to create a virtual optical drive, which can do everything what could be done with the physical. Another advantage of such a method works is that the transfer of such data to the virtual CD-ROM argim or DVD much faster than the physical, it is not necessary argim laser-read optical media and transfer data from it to the hard drive, but everything happens within the framework of hard drive. To download the optical disc somewhere on the other end of the world as we do not need envelopes for CD and postage, it can image the media sent via the Internet than any other file. Needless to say, this kind of valuable data stored also much safer than if they were stored on optical argim media. Hard disk is safely stored in a metal box which further protects the computer chassis or enclosure external drive, optical media, we all know how fragile argim they are. If we file safely brought to possibly more than one hard drive, a few scratches on the plastic will not be able to spoil the day.
Images of optical discs are also very popular among legal and illegal exchangers files as they are ideal for the distribution of content argim that otherwise distributed on optical media, such as programs, games and operating systems. In this context, it is well to remember that these files may also contain various viruses, Trojans, rootkits and other dirt on which images of optical disks, of course, are not immune. Therefore, caution should be exercised when working argim with files that we've got somewhere in the Internet, not redundant. In general, we will focus free program that allow you mount images of optical media.
Mounting (mounting) is a process simulation software that creates a virtual optical drive. This will be recognized by the computer argim exactly as it would recognize the physical. Some of programs for editing these files also allow the creation of optical media files, converting them to other formats, and the like, although these purposes generally argim useful programs for "baking" of optical discs (CDBurnerXP, Nero, DeepBurner ...). Before you create the belief that these programs are absolutely necessary, applies also to know that the images of optical media (as I mentioned argim earlier) in close kinship with archive files such as. Zip,. Rar., 7z., Tar.gz and the like. Therefore, in many cases, can file. Iso. Bin., Or other more well-known image formats easily opened by programs to work with archive files such as the. 7zip and WinRAR. It sometimes does not work when you are dealing with copies of the programs or games, even bigger obstacle is endless confusion in the field of formats. FORMATS, FORMATS FORMATS AND AGAIN ...
About all formats appearing on the work with images of optical disks, it would probably be cataloged the entire magazine. But this is one of those areas where the format even more crowded than anywhere else. It's good to show that every commercial program unable to exercise their own, commercial format. Most image formats of optical discs is so commercial and closed, we are working problems, as they often can be opened only by their own program. The only more or less
