To understand the term "pixel", it is necessary to imagine that the whole world consists of particles: a collective of individuals, a person consists of molecules, which are an ordered accumulation of atoms. A pixel is a part of a graphic image or object.
Instructions
Step 1
At its core, a pixel is nothing more than a point. You've probably heard that the resolution of a screen or photo can be measured in pixels. In other words, an image, like a mosaic, consists of parts, the smallest of which is a pixel.
Step 2
To see the pixels, it is enough to enlarge the photo using a graphics editor or viewer. If you see the points that make up the image, know that they are pixels. Open any photo from your hard drive, if you don't have them, navigate to the My Pictures folder, which is located in the My Documents folder.
Step 3
In the folder that opens, double-click on the "Sample Pictures" shortcut, and then on one of the available photos. In the image viewer, find the Larger + tool and use it, zoom in until the keypoints appear.
Step 4
Also, the number of pixels used in monitor resolutions can be found in the Display Properties applet. To do this, right-click on the desktop and in the context menu select "Properties" (for Windows XP) or "Screen resolution" (for Windows 7).
Step 5
In Windows XP, go to the "Settings" tab, in the "Screen resolution" section, the value of the current resolution will be indicated, for example, 1024 by 768 pixels. To change it, just move the slider to one side and click the "Apply" button, so you will see that the number of dots affects the quality of displaying the picture and icons on the desktop.
Step 6
In Windows 7, the resolution setting is on the first tab of an open window. Above the slider for the number of pixels there is a preview window of the result, before applying one or another mode, you can see how it will look.
Step 7
To view the number of pixels of images or photos, you need to call the properties of the viewed file. Right-click on the picture icon and select "Properties". In the window that opens, go to the "Summary" tab and click the "Details" button. The value of the "Width" and "Height" strings is the number of pixels.
