Loading a program involves either memory-mapping or copying the contents of the executable file containing the program instructions into memory, and then carrying out other required preparatory tasks to prepare the executable for running. Once loading is complete, the operating system starts the program by passing control to the loaded program ...
Fast Hack'em was updated often, and later versions added more copying options. The one feature that stood out from other copying programs was that these updates include parameters. They include the methods of copy protection individual programs use so even a fast copy can then be artificially re-protected and give a working copy.
In computing, a system image is a serialized copy of the entire state of a computer system stored in some non-volatile form, such as a binary executable file.. If a system has all its state written to a disk (i.e. on a disk image), then a system image can be produced by copying the disk to a file elsewhere, often with disk cloning applications.
Installation (or setup) of a computer program (including device drivers and plugins), is the act of making the program ready for execution. Installation refers to the particular configuration of software or hardware with a view to making it usable with the computer. A soft or digital copy of the piece of software (program) is needed to install it.
A zip bomb allows a program to function normally, but, instead of hijacking the program's operation, creates an archive that requires an excessive amount of time, disk space, or memory to unpack. [2] Most modern antivirus programs can detect zip bombs and prevent the user from extracting anything from it. [3]
An example of non-orthogonal persistence using a system image is a simple text editing program executing specific instructions to save an entire document to a file. Shortcomings: Requires enough RAM to hold the entire system state. State changes made to a system after its last image was saved are lost in the case of a system failure or shutdown.
In computing, Windows on Windows (commonly referred to as WOW) [1] [2] [3] is a discontinued compatibility layer of 32-bit versions of the Windows NT family of operating systems since 1993 with the release of Windows NT 3.1, which extends NTVDM to provide limited support for running legacy 16-bit programs written for Windows 3.x or earlier.
Application virtualization is a software technology that encapsulates computer programs from the underlying operating system on which they are executed. A fully virtualized application is not installed in the traditional sense, [1] although it is still executed as if it were.
