This document discusses the parts of a desktop computer. It identifies five main parts: 1) program files/icons which launch programs and open files, 2) the start button which displays the start menu listing programs, 3) the taskbar at the bottom of the screen displaying open windows, 4) the time box showing the current time, and 5) the desktop which is the main working environment. The document provides examples and screenshots to illustrate these parts and their functions. Students are instructed to locate the parts using the mouse pointer and complete a short assignment identifying additional desktop parts and their functions.
