Hi all. I need an Ethernet cable that goes from one of these ends to the other. What would I call it so that I can search for it and buy it on the internet?

Thanks in advance.

Thanks all - turns out I was being really dense. Thanks to the commenters who helped me sort out my thickness!

    The smaller end is RJ12, the bigger end is RJ45.

    The question is, what are you trying to do with it? RJ12 is/was typically used for telephone connections, RJ45 for Ethernet. Generally speaking, they don’t mix.

    If your plan is to connect a computer to a RJ12 socket on the wall, that’s not going to work. If you’ve been told the socket on the wall is “the internet”, you’re likely going to need a modem in between that socket and your computer.
