What is screen resolution
Screen resolution is one of those IT terms that people use without necessarily knowing exactly what it means. We thought it was about time we explained it.
Screen resolution is the number of pixelsThe image on your computer screen is built up from thousands or millions of pixels. The screen creates the image you see by changing the colours of these tiny square elements.
The screen resolution tells you how many pixels your screen can display horizontally and vertically. It's written in the form 1024 x 768. In this example, the screen can show 1,024 pixels horizontally, and 768 vertically.

Decibel Table − SPL − Loudness Comparison Chart
To get a feeling for the heard sound quantities in decibels (dB), look at the table below which gives values for the sound levels of common sounds in our environment. Also shown are the corresponding sound pressures and sound intensities with the absolutely necessary measuring of the distance. From these we can see that the decibel scale gives numbers in a much more manageable range. Sound pressure levels are measured without weighting filters.
