For the avoidance of doubt .DMG information aren't really "pictures" of Apple Mac software. Instead the .DMG file extension identifies Macintosh OS X (ie the most recent version of the Mac operating system) disk picture files. In the context of IT and pc software program the phrase "disk picture" means something aside from what we might otherwise perceive to be a photograph of a disk, or an icon depicting a disk.
Indeed, on this context, "disk images" are comparable (if still very distinct) to software copies and laborious disk backups. The normal copying of a CD, DVD, arduous disk, or different media, would require that the pc learn the file structure of the media and duplicate that throughout to somewhere else. Nonetheless this solely works if the PC has entry to all those information: your PC won't (or at the least not easily) be capable to copy information which might be protected, encrypted or otherwise not designed to be read by the system (such because the content of bootable disks).
By contract disk imaging software program takes a special strategy, in that it duplicates the knowledge actually on the CD, DVD, or other media, directly. By copying the individual bits of data from the source media the disk imaging software program can create a perfect duplicate of the original content.
There are a selection of purposes of the precept of disk imaging. At first the expertise was used simply to backup a tough drive, or create a clone of floppy media or a CD/DVD. Nevertheless it is now a preferred methodology for creating complete system backups which allow the system administrator to get better a damaged computer by loading the disk image of a previous configuration of that PC.
Equally, in fashionable company environments, the place there are numerous identically configured PCs, programs administrators will not install all of the software program on each single laptop, each single time. As a substitute they'll configure one system accurately, then clone it (ie create a hard disk picture) to every new PC they want (also referred to as ghosting). |
