Text 1 – The Computer Monitor
A computer monitor is an output device that displays information processed by a computer. It looks similar to a television, but it is specifically designed to display text, images, videos, and other visual information from a computer. Modern monitors usually use LED or LCD technology because these technologies produce clear images while consuming relatively little electricity.
One important feature of a monitor is its resolution. Resolution refers to the number of pixels that can be displayed on the screen. A higher resolution generally produces sharper and more detailed images. The monitor also has several buttons or controls that allow users to adjust brightness, contrast, and other display settings.
Monitors come in different sizes, usually measured diagonally in inches. A larger screen can make it easier for users to work with several windows simultaneously. However, a larger monitor does not automatically mean that its image quality is better.

Alphabetic keys are used to type letters, while numeric keys allow users to enter numbers. Function keys, usually labeled F1 through F12, can perform different commands depending on the software being used. Navigation keys, such as the arrow keys, help users move the cursor or navigate through documents.
