is an apparent human ability to perform more than one task, or activity, over a short period (1 hour). An example of multitasking is taking phone calls while typing an email and reading a book. Multitasking can result in time wasted due to human context switching
and apparently causing more errors due to insufficient attention
. Studies have shown that it is impossible to focus on more than one task at a time. However, if one is proficient at one of the tasks at hand, then it is possible to do these tasks.
