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”

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 ???
Generally no - USB connections are asymmetric, with hosts and devices. Your PCs are both hosts - they cannot function as devices or communicate with other hosts.
It’d be like you trying to fill up 2 swimming pools with one hose, pumping water into each end, right?
