This isn't a clearly worded question, but if I understand correctly, you want to know how many pixels there are in such a display. Well, 640*480=307200.
Image resolution is usually expressed by giving the dimensions of the image in pixels. The size of an image that is 640 pixels wide and 480 pixels tall would be expressed as 640x480. 640x480 is read as "six forty by four eighty".
640x480 has more pixels, therefore it is sharper. Bigger numbers mean more pixels. More pixels make a sharper picture. 640x480= 307 200 pixels 640x360= 230 400 pixels
Probably author means pixel dimensions of photo like this one: 640X480 px in other words Width and Height in pixels because bit mapa is pixel grid of an image.
The standard accepted pixels for a web page is 640x480. This number is up from the previous standard of 480x360. Of course, the page can have more or less pixels, but it can affect the images.
VGA stands for Video Graphics Array. It is an old standard used for monitors and other displays. 640x480 refers to the number of pixels per inch, known as DPI.
Depends of the number of pixels per centimetres or inch (Ppi- pixel per inch).
The VGA board is always enabled, but, VGA is defined by the number of pixels you have your computer display set at. For instance, if you go into Control Panel>display you will see what your pixels are set at. VGA is 640X480, XGA is 800X600 and SVGA is 1024X768. So if you change your pixels to 640X480 then you will have VGA.
pixel is already singular, the plural for it is pixels.

Mega pixel webcam are performing much better that the vga webcams.Its depending on the resolution of each webcam.For example:1MP=1000000pixesVga resolution is equal to 640x480 pixels , that means 307200 pixels.A mega pixel webcam should deliver 1280*1024 screen resolution, which is arround 1.3mega pixels=1310720pixels.In other words megapixel webcam have much better performance than vga webcams
