A terminate-and-stay-resident program (commonly TSR) is a computer program running under DOS that uses a system call to return control to DOS as though it has finished, but remains in computer memory so it can be reactivated later. [1] This technique partially overcame DOS's limitation of executing only one program, or task, at a time.
A terminal multiplexer can be thought of as a text version of graphical window managers, or as a way of putting attach virtual terminals to any login session.It is a wrapper that allows multiple text programs to run at the same time, and provides features that allow the user to use the programs within a single interface productively.
Virtual DOS machines can operate either exclusively through typical software emulation methods (e.g. dynamic recompilation) or can rely on the virtual 8086 mode of the Intel 80386 processor, which allows real mode 8086 software to run in a controlled environment by catching all operations which involve accessing protected hardware and forwarding them to the normal operating system (as exceptions).
GNU Screen can be thought of as a text version of graphical window managers, or as a way of putting virtual terminals into any login session.It is a wrapper that allows multiple text programs to run at the same time, and provides features that allow the user to use the programs within a single interface productively.
A similar model is used in Windows 9x and the Windows NT family, where native 32-bit applications are multitasked preemptively. [10] 64-bit editions of Windows, both for the x86-64 and Itanium architectures, no longer support legacy 16-bit applications, and thus provide preemptive multitasking for all supported applications.

In addition, four environments are provided containing native compilers, build tools and libraries that can be directly used to build native Windows 32-bit or 64-bit programs. The final programs built with the two native environments don't use any kind of emulation and can run or be distributed like native Windows programs.
Note: Wait for 20 seconds, and then turn on the computer. 2. On the keyboard, hold down the Command and Option keys, and then tap the esc key. In the Force Quit Applications window, click any program other than Finder to highlight it, and then click Force Quit. 3.
