Plain-English definition
SaaS
What it means
SaaS, or software as a service, is software people use over the internet through their browser instead of installing it on their own computer. The company that makes it runs it, updates it, and keeps it working, so users just log in and go.
In plain terms
Like using a laundromat's machines instead of buying and maintaining your own: they're always there, always ready, and someone else keeps them running.
