computer displays, a computer icon is a small
pictogram. Icons have been used to supplement the normal alphanumerics of the computer. Modern computers now can handle bitmapped graphics on the display terminal, so the icons are widely used to assist users.A computer icon usually ranges from 16 by 16
pixels up to 128 by 128 pixels. Some
operating systems feature icons up to 512 by 512 pixels. When the
graphical output device has a smaller size, the icon size is small. Vision impaired users (due to such conditions as poor lighting, tired eyes, medical impairments, bright backgrounds, or
color blindness) may need to utilize the self-selected icon size options.
