Hey Computer Guys. I Bought A Laptop. Parts Help.

I just got a new computer. It’s a laptop for my kid and me. I don’t know what this is and there’s no real instructions with this.  It was in the box and also the four screws in the last picture. 




Its a hard drive connector

in. just got a laptop a couple weeks ago. ive had a little bag with 4 tiny screws sitting on my counter since i opened it. 

looks like a hard drive connecting cable, the screws might mount the hard drive inside there.
