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 ???
It’s not an officially sanctioned application of USB, but some product vendors use it for various reasons. After all, a USB cable is just a bunch of wires (some twisted together a special way).
One example that springs to mind is the HTC Vive link box. This was made before USBC was very popular, and I’m guessing they wanted USB 3 speeds with a lower profile connector. Typically, you’d use an A to B cable, but the B connector is much taller.
Thanks for the info, I have another question. Can it be used to connect one pc to another maybe for sharing files or for doing some other stuff ?
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?
Nope. Computer USB A ports are “upstream ports.” Both computers would be expecting to find a downstream device on the port. USB needs a single host to control everything. Can’t have two hosts.
If it was already tried with this specific cable and it didn’t work, then this cable doesn’t have the capability built in. Some cables like this have a bridge in the cable that allows pc to pc communication.
Laplink is a major product that still does this. In the center is a controller that acts as a device to both ends, letting both PCs act as a host.
It still requires their software to make use of this connection, though.
Not without special support from the hardware and software. But a smartphone is pretty much a PC with specialized hardware and software. And you can certainly plug your smartphone into a PC to share photo’s.
