What's this cable used for ? - Lemmy.world

I don’t know much about cables so if type something wrong forgive me … I was wondering around with some old stuff, and found this cable that is usb to usb “as shown in the image below” https://m.media-amazon.com/images/I/71hHpyqvvnS._AC_UF1000,1000_QL80_FMwebp_.jpg [https://m.media-amazon.com/images/I/71hHpyqvvnS._AC_UF1000,1000_QL80_FMwebp_.jpg] Now what i thought was that it might be used to connect 2 computers with each other so i tried that and connected 2 computers with each other using it and nothing happened Can anyone tell me what this cable is even used for ???
