Unlike the daily doses of humor that Kim_Johnson provides for us, I tend to only tell the one joke a year and it is the same joke every year, regarding my new year’s resolution… I mentioned that mine was 300dpi
But I don’t think most of you got the joke, so I am going to have my TA explain it to you
Print resolution is three hundred dots per inch, often abbreviated to 300dpi. There is some dispute over screen resolution, which is either 96dpi or 72dpi. I've heard it both ways...
DPI is a relative measurement, as it is predicated on inches. Notice the TA is showing you how the same pixel dimensions would translate into different dpi measurements
