The document defines computer hardware and identifies its five primary groups: input devices, output devices, input/output devices, working storage, and permanent storage. It provides examples of common computer hardware that fall within each group, such as keyboards and mice as input devices; monitors and printers as output devices; and RAM and hard disk drives to differentiate working and permanent storage.

1. Lesson Objectives:
• Define what is computer hardware;
• Enumerate the five primary groups
of computer hardware;
• Differentiate primary groups of
computer hardware; and
• Classify computer hardware
devices according to their groups.

2. -refers to the physical parts of a
computer and related devices. Internal
hardware devices
include motherboards, hard drives,
and RAM. External hardware devices
include monitors, keyboards, mouse,
printers, and scanners.
