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 ???

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.
