Multitasking | FrendlyOS

Multitasking, in the context of operating systems and software, refers to the ability of a computer to execute multiple tasks or programs concurrently. Historically, early computers were single-tasking, executing one instruction at a time. The advent of time-sharing and preemptive multitasking in systems like CTSS (Compatible Time-Sharing System) in the 1960s, and later refined in Unix and modern OSes like Windows and macOS, allowed for the illusion of simultaneous operation by rapidly switching CPU time between processes. This has profoundly shaped user interaction, enabling complex workflows and the seamless integration of applications, though the cognitive load on the human user remains a significant, often overlooked, factor.
