That lens was made in many different mounts. You can search eBay to see if you can match up the lens with a particular mount.
If it is a Nikon mount(except non AI) or Pentax K mount, you will be able to use it on a current Nikon or Pentax DSLR camera. If it is one of the other manual focus mounts from the film camera era, you will need an adapter to fit a modern DSLR. Some mounts can be easily adapted to Modern cameras, and some can’t. Mirrorless cameras are designed to have the lens mounted close to the image sensor, and this makes it easier to use old film era lenses with adapters.
The lens sells for about $25 on eBay and is probably not worth the effort as results will be disappointing.
Here are a few examples of this lens in different mounts taken from from eBay listings.
