The act of reassigning a CPU from one task to another one is called a context switch.

A context switch can mean a register context switch, a task context switch, a thread context switch, or a process context switch.

When a task switch occurs the CPU can automatically load the new state from the TSS.

Some applications allow the user to switch between these modes at their choosing, depending on personal preference or the task at hand.

Speech synthesizers are also commonly used for the same task, and a blind user may switch between the two systems or use both at the same time depending on circumstances.

For example, with a 20 MHz 68000 processor ( typical of late 1980s ), task switch times are roughly 20 microseconds.

However, multitasking allows each processor to switch between tasks that are being executed without having to wait for each task to finish.

A Critical Chain project network will tend to keep the resources levelly loaded, but will require them to be flexible in their start times and to quickly switch between tasks and task chains to keep the whole project on schedule.

If all processes share a single address space, then the only way could be implemented would be to swap the memory pages along with the rest of the task context switch.

Quarterdeck's predecessor to DESQview was a task switching product called Desq ( shipped late April or May 1984 ) which allowed users to switch between running programs.

Pressing the Alt key by itself would bring up the DESQview menu allowing access to the program's features: start new tasks, switch among them, mark text on the screen, paste text as input into the current task, resize or move the text windows, configure new menu items, etc.

A team may choose to switch tasks as many times as they wish with no penalty other than the time lost in attempting the tasks and traveling between task locations.

Another example in the Intel Pentium Pro, the page global enable ( PGE ) flag in the register CR4 and the global ( G ) flag of a page-directory or page-table entry can be used to prevent frequently used pages from being automatically invalidated in the TLBs on a task switch or a load of register CR3.

Thus a context switch will not result in the flushing of the TLB – but just changing the tag of the current address space to the tag of the address space of the new task.

Colonies allocate workers to different tasks, and workers switch from one task to another in response to changing conditions.

Fields are often surrounded by obstacles such as trees, telephone lines, and farm buildings, so pilots have to switch quickly from the task of dropping chemicals accurately and smoothly to the task of dodging obstacles.

Support was added for the DR DOS task switcher TaskMAX ; if this was present, applications would be launched as separate tasks, and ViewMAX could switch between them.

This way the task can be accomplished with a simple one-handed movement, while keeping the weapon stationary.

In this context, a computational problem is understood to be a task that is in principle amenable to being solved by a computer ( i. e. the problem can be stated by a set of mathematical instructions ).

For this reason, the task of orthodox Marxism, its victory over Revisionism and utopianism can never mean the defeat, once and for all, of false tendencies.

Research has indicated that learners who are better at goal-setting and self-monitoring tend to have greater intrinsic task interest and self-efficacy ; and that teaching learning strategies can increase academic achievement.

The time it would take to write such a number also renders the task implausible: if a person can write two digits per second, it would take around about 1. 51 years, which is about 1. 1 times the age of the universe, to write a googolplex.

This task can be divided into three required steps:

* Decision / reaction time / speed ( Gt ) reflects the immediacy with which an individual can react to stimuli or a task ( typically measured in seconds or fractions of seconds ; it is not to be confused with Gs, which typically is measured in intervals of 2 – 3 minutes ).

Separation of duties ensures that an individual can not complete a critical task by himself.

When a given task is appropriate for a team, task design can play a key role in team effectiveness ( Sundstrom, et al., 2000 ).

Such expansions of team task assignments can make teams more effective and require teams to spend greater amounts of time discussing and planning strategies and approaches for completing assigned tasks ( Hackman, et al., 1976 ).

These theories assume that an effective leader can accurately " read " a situation and skillfully employ a leadership style that meets the needs of the individuals involved and the task at hand.

What is knowledge representation can best be understood in terms of five distinct roles it plays, each crucial to the task at hand:

There should be a task for everyone and these tasks should be rotated.

These are usually ' temps ' ( temporary workers ) or consultants who, depending on the project and their experience, might be brought on to lead a task for which the skill-set did not exist within the company, or in the case of a temp, in the vernacular sense, to perform busy-work or an otherwise low-skilled repetitive task for which an employee is deemed too valuable to perform.

In the case of a computer with a single CPU, only one task is said to be running at any point in time, meaning that the CPU is actively executing instructions for that task.
