Default Why using short reads?

Hi, everyone. I'm a newbie here.

I have a question that always baffles me that why NGS only uses short sequence tags?

Instead sequence the whole DNA fragments, it only sequences the first 25-50 bp of a DNA fragment.

Is there a particular reason for doing this?

Thank you!
