Introduction: Computer classification based on physical size and form factor ranges from handheld mobile devices to large-scale enterprise servers.
Information Booster:
· Tablet (D): The smallest among the options; a handheld device primarily operated via a touchscreen.
· Notebook Computer (B): Also known as a laptop; larger than a tablet but designed for portability.
· Desktop Computer (C): A stationary computer meant to sit on a desk; larger and not designed for frequent movement.
· Mini Computer (A): In technical hierarchy, "Mini" is a bit of a misnomer today; historically, these were mid-sized multi-user computers larger and more powerful than a standard personal workstation (Desktop).
Additional Knowledge:
· While "Mini" sounds small, in the history of computing, the sequence from smallest to largest is Microcomputer (PC/Laptop/Tablet) < Minicomputer < Mainframe < Supercomputer.
