What's the difference between photoshop and coral draw?

The main difference is that Photoshop is a raster graphics editor while Corel is vector graphics editor

Coral Draw is A vector based program can make a vector art file as large as we want. Adobe Photoshop is a pixel based program that uses small squares of color to make a picture. 

I can say photoshop and other image editing software is Raster and pixel based software 

for coral draw is the vector Based software although you can edit
