This can be done as part of the previous stage, or within a small code segment at the beginning of the program. If address space is assigned externally, such as in an application program that is run on a system that does not provide virtual memory, the compiler needs to access all modifiable data by adding an offset to a pointer to a private ...
copying the command-line arguments into virtual memory; initializing registers (e.g., the stack pointer); jumping to the program entry point (_start). In Microsoft Windows 7 and above, the loader is the LdrInitializeThunk function contained in ntdll.dll, which does the following:
An abstraction layer that allows legacy code to operate on more modern versions of Windows; typically this means running 16-bit Windows applications on 32-bit Windows, and 32-bit applications on 64-bit Windows. Virtual DOS machine: NTVDM
Microsoft Windows divides virtual address space into two regions. The lower part, starting at zero, is instantiated separately for each process and is accessible from both user and kernel mode. Application programs run in processes and supply code that runs in user mode.
Disk cloning is the process of duplicating all data on a digital storage drive, such as a hard disk or solid state drive, using hardware or software techniques. [1] Unlike file copying, disk cloning also duplicates the filesystems, partitions, drive meta data and slack space on the drive. [2]
Shadow Copy (also known as Volume Snapshot Service, [1] Volume Shadow Copy Service [2] or VSS [2]) is a technology included in Microsoft Windows that can create backup copies or snapshots of computer files or volumes, even when they are in use. It is implemented as a Windows service called the Volume Shadow Copy service.

File copying is a fundamental operation for data storage. [citation needed] Most popular operating systems such as Windows, macOS and Linux as well as smartphone operating systems such as Android contain built-in file copying functions as well as command line (CLI) and graphical (GUI) interfaces to filing system copy and move functions. In some ...
