Human multi tasking !

Human multitasking is the performance by an individual of appearing to handle more than one task at the same time. The term is derived from computer multitasking. An example of multitasking is listening to a radio interview while typing an email. Some believe that multitasking can result in time wasted due to human context switching and apparently causing more errors due to insufficient attention

Media multi Tasking..

Media multitasking involves using TV, the Web, radio, telephone, print, or any other media in conjunction with another. Also referred to as "simultaneous media use," this behavior has emerged as increasingly common, especicially among younger media users,[1] and has gained significant attention in media usage measurement, especially as a new opportunity for cross-media advertising.[citation needed]

Much of this multitasking is not inherently coupled or coordinated except by the user. For example a user may be browsing the Web, using e-mail, or talking on the phone while watching TV. More directly coordinated forms of media multitasking are emerging in the form of "coactive media" and particularly "coactive TV."

computer multi tasking

In computing, multitasking is a method where multiple tasks, also known as processes, share common processing resources such as a CPU. 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. 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. The act of reassigning a CPU from one task to another one is called a context switch. When context switches occur frequently enough the illusion of parallelism is achieved. Even on computers with more than one CPU (called multiprocessor machines), multitasking allows many more tasks to be run than there are CPUs.

Operating systems may adopt one of many different scheduling strategies, which generally fall into the following categories:

In multiprogramming systems, the running task keeps running until it performs an operation that requires waiting for an external event (e.g. reading from a tape) or until the computer's scheduler forcibly swaps the running task out of the CPU. Multiprogramming systems are designed to maximize CPU usage.
In time-sharing systems, the running task is required to relinquish the CPU, either voluntarily or by an external event such as a hardware interrupt. Time sharing systems are designed to allow several programs to execute apparently simultaneously. The expression 'time sharing' was usually used to designate computers shared by interactive users at terminals, such as IBM's TSO, and VM/CMS
In real-time systems, some waiting tasks are guaranteed to be given the CPU when an external event occurs. Real time systems are designed to control mechanical devices such as industrial robots, which require timely processing.
The term time-sharing is no longer commonly used, having been replaced by simply multitasking, and by the advent of personal computers and workstations rather than shared interactive systems.
