The concept of humans doing multiple things at a time has been studied by psychologists since the 1920s, but the term “multitasking” didn’t exist until the 1960s. It was used to describe computers, not people. Back then, ten megahertz was so fast that a new word was needed to describe a computer’s ability to quickly perform many tasks. In retrospect, they probably made a poor choice, for the expression “multitasking” is inherently deceptive. Multitasking is about multiple tasks alternately sharing one resource (the CPU), but in time the context was flipped and it became interpreted to mean multiple tasks being done simultaneously by one resource (a person). It was a clever turn of phrase that’s misleading, for even computers can process only one piece of code at a time. When they “multitask,” they switch back and forth, alternating their attention until both tasks are done. The speed with which computers tackle multiple tasks ________________ that everything happens at the same time, so comparing computers to humans can be confusing. [3점]
