Multitasking solves the problem by scheduling which task may be the one running at any given time, and when another waiting task gets a turn.
In computing, multitasking is a method by which multiple tasks may execute, apparently simultaneously, on a single computer processor.

 Computer multitasking - Encyclopedia, History, Geography and Biography
Although multitasking techniques were originally developed to allow multiple users to share a single machine, it soon became apparent that multitasking was useful regardless of the number of users.
Another reason for multitasking was in the design of real-time computing systems, where a number of possibly unrelated external activities needed to be controlled by a single processor system.
Typically, a multitasking system allows another process to run when the running process hits a point where it has to wait for some portion of memory to be reloaded from secondary storage.

 The Digital Research Initiative
Computers which are capable of "preemptive multitasking" are generally more powerful than those which are simple "multitasking" computers.
As a rule, most computers are powerful enough to handle preemptive multitasking, at least those made since the mid-1980s, but usually these computers don't have that ability because of the limitations of their operating systems.
It should be also noted that "preemptive multitasking" is an elusive goal for many operating systems, as very few are able to achieve this ability, Some companies claim their system is preemptive multitasking, when it is really not.

a much easier way to handle multitasking is to have all the programs switch their own contexts out periodically.
the type of multitasking you use also relates to the way your OS passes input to a program, and there are two ways of doing *that*, too.
translating that to OS terms, the computer's hardware triggers an electrical signal much like the ring of a telephone (called an interrupt) every time a key is pressed or the mouse is moved.

A computer program or routine is described as reentrant if it is designed such that a single copy of the program's instructions in memory can be shared by multiple users or separate processes.
The key to the design of a reentrant program is to ensure that no portion of the program code is modified by the different users/processes, and that process-unique information (such as local variables) is kept in a separate area of memory that is distinct for each user or process.
Reentrant programming is key to many systems of multitasking.
