Final answer:
A workgroup is a group of interconnected computers that share resources without a central server, reflecting the shift from centralized minicomputer systems to distributed personal computing.
Step-by-step explanation:
A workgroup is a group of interconnected computers that share each other's resources without relying on a central server. This means that in a workgroup, each computer functions as a peer to the other, with no one machine having control over another. This concept is part of the evolution of personal computing, moving away from the era of the minicomputer, which was a computer that supports many users at once and had lower computing capacity than a mainframe, to a more distributed and personalized computing paradigm. Personal computing has seen a transition from a single desktop meant for the whole family to individual devices fostering a truly "personal" relationship with technology. In today's workgroups, powerful personal computers can connect directly to each other to share resources such as files, printers, and internet access.
