Think of one worker at one desk with four jobs waiting on it. Nothing is truly done at the same moment: the worker touches one job, drops it, picks up the next, and comes back. Speed is what makes it look like everything is moving together.
From the word’s history
multi- (many) + task + -ing. The source marks the human use as figurative, which points to the computing use as the earlier one.
由 multi-（多）加 task（工作）加 -ing 組成，字面就是「同時進行多項工作」。來源資料把講人的意思標為比喻用法，也就是先有電腦那層，才有人的那層。
