I see this term thrown out a lot, and I just simply do not understand it.

"100% Crop"

I don't quite understand what that means.

Can anyone explain it, and if possible, show me a picture, and then a 100% crop of it?

Thanks,

Ron
 
It's like showing a part of an image only.

Just to expand on that....When you record a digital photo, it will have a certain size (number of pixels). It might be 4272 x 2848 for example.

Now, a computer monitor might be set to a resolution of 72 pixels per inch...so in that case, at 100% zoom, the image would be 59.3 inches wide. So unless your monitor is more than 60" wide, you wouldn't see the whole image on the screen (at 100% zoom).
This is why we resize our images for displaying on the web. I usually scale down my images to about 800 pixels wide, which is just over 11 inches at 72 PPI. That way, the whole image will fit on most monitors.

But of course, you can't really show the tiny details of an image when it's resized so much. So when we want to show the detail of an image, without having to post a huge image...we just crop out a section that will fit on the screen at 100% zoom.
 
It means that you have taken a crop of the image such that 1 pixel in the image corresponds to 1 pixel on your monitor.
 
Few computer displays are still 72 PPI (pixels-pre-inch).

To determine the PPI of your display you need to note the resolution your display is set to (my 22" (diagonal) is set to 1600 x 1200). Then measure the width of the display and divide by the pixel width.

My 22" (diagonal) display is 18 5/8 inches (18.625) wide, so 1600 pixels divided by 18.625 = 85.91 pixels-per-inch (PPI).
 
Thank you for taking the time to elaborate, it made a lot more sense after this post.
