I was gonna say that I have to sometimes refer to it as "RJ45” port, because we actually also work with differently shaped Ethernet ports. Then I decided to look up, if that's specifically the name of the plug or of the port as well.
And Wikipedia is immediately like, oh yeah, the scrubs refer to it as "RJ45", when it was really named after the "RJ45S" standard. But that standard actually describes a specific, obsolete wiring configuration of what's really an 8P8C connector.
I'm not calling out the mistranslation, obviously. I'm calling out The Simpsons -related gag above it which turns the mistranslation into a racist joke.
Let me know if you need any help understanding. Or maybe you could ask your educational institution, assuming that you went to one.
I'm currently reading though ways to DIY an internet hole into my car hole. Now I see the folly of searching for articles using terms like rj45 keystone and garage.
