Multitasking is a feature of modem operating systems that we all take for granted.1 After all, we expect to be able to run a word processor and an e-mail program at the same time and not have them be in conflict, or have the word processor stop working if e-mail needs to be downloaded. Of course, what actually happens is that the operating system rapidly switches between the programs that are running on the CPU (unless you have multiple CPUs of course). This gives the impression that multiple programs are running at the same time, because even the fastest typist (or for that matter, the fastest Internet connection) cannot keep up with the speed of even one modern CPU.
