Lesson Content

I. Definition of a Computer Monitor

A computer monitor is an electronic output device that displays visual information, including text, images, and videos. It allows users to interact with the computer by providing a graphical interface.

II. Description of a Monitor as an Output Device

A monitor is classified as an output device because it receives and displays data from the computer. It does not process or store information but presents it visually to the user.

III. Types of Computer Monitors

1. Monochrome Monitor:
   • Displays information in only one color (black and white or green and black).
   • Used in older computer systems and some specialized applications.
2. Color Monitor:
   • Displays multiple colors and is used in modern computers.
   • Available in different technologies such as CRT (Cathode Ray Tube), LCD (Liquid Crystal Display), and LED (Light Emitting Diode) screens.

IV. Identifying the Prompt and Cursor

• Prompt: A signal on the screen that indicates the computer is ready for user input. Example: The blinking text in a command prompt.
• Cursor: A movable indicator, often a blinking line or arrow, that shows where text will appear when typed or where actions will take place on the screen.
