Human multitasking is the apparent performance by an individual of handling more than one task, or activity, at the same time. The term is derived from computer multitasking. An example of multitasking is taking phone calls while typing an email. Multitasking can result in time wasted due to human context switching and apparently causing more errors due to insufficient attention. However, studies have shown that some people can be trained to multitask where changes in brain activity have been measured as improving performance of multiple tasks (see below: The brain's role). Multitasking can also be assisted with coordination techniques, such as taking notes periodically, or logging current status during an interruption to help resume a prior task midway. ==Etymology== The term "multitasking" originated in the computer engineering industry.〔(ComputerUser, Inc. definition )〕 It refers to the ability of a computer to apparently process several tasks, or computer jobs, concurrently.〔"You say Multitasking like it's a good thing" by Charles J. Abate, March/April 2009 issue of ''NEAtoday''〕 Computer multitasking in single-CPU microprocessors actually involves time-sharing of the processor; only one task can actually be active at a time, but partial work on each task is rotated through many times a second. With multi-core computers, each CPU can perform a separate task simultaneously.
The first published use of the word "multitask" appeared in an IBM paper describing the capabilities of the IBM System/360 in 1965.〔(IBM Operating System/360 Concepts and Facilities ) - Witt, Bernard I. & Lambert, Ward〕
