Connectors Quiz!

Twaggies presents another quiz, which this time will have you in knots of frustration behind the media center.



  1. The correct answer is not offered on several of the questions, so I selected the least wrong ones.  And got 100%, even though I’ve never heard of that spade connector thingy.

  2. Oh, they really turned up the easy mode on this one.

    I absolutely knew that I was out of the woods when the correct answer was “SCSI connector”, rather than “Which May god have mercy on your doomed soul…”

    1. Oh, man, good times. “I’ve got a Jaz, a Zip and an external CD-ROM, and they’re all SCSI, and they all have different ports.”

      (Bonus fun : “Which one(s) need a terminator and where, and what order do they need to go in?”)

      There are some things I miss about the old Macs. SCSI voodoo is not one of them. 

  3. “Ethernet connector” should be labelled ‘RJ45 connector” (It’s used for more than Ethernet)
     (bonus question should have been ‘straight-thru or crossover?’)

    VGA connector might be known as a SVGA connector (wrong # of pins) Although I will admit VGA connectors don’t show up much in the field, but that’s a topic for legacy nitpickers.

  4. Their testing methodology leaves a bit to be desired – as someone else noted, they have some examples named by their use and others named by their connector type. Also, if you’re going to ask us to identify a type of connector, don’t show it to us in such a way as to occlude part of the connector. The PS/2 example where I couldn’t see half the pins made that one a little harder.

  5. Yes, don’t confuse connector styles with the signals carried on them.  For instance there’s no such thing as an “RS232 connector”- while it’s common to see it on a DE9, there’s actually no connector specified in the spec.

  6. I was hoping that there would be some obscure connectors. The USB 3 was the closest thing to obscure, as it’s brand-new. And to the person who called the SCSI connector a Centronics connector, the number of pins is important. SCSI is 50, Centronics is 36. They’re actually Amphenol ribbon connectors, dating from the 1960s and first used in telephone systems.  A larger version was used in the back of Tektronix oscilloscope plug-ins in the 1950s.

    I could go on, but I won’t.

    1. Actually both the 36-pin and the 50-pin are “Centronics” connectors. The key factor is the plastic bar in the center of the connector body that holds the contact pins, regardless of how many there are.

  7. Yeah, I was expecting something challenging. I suppose we could use it a work to weed out the dimmest of job candidates.

  8. If there was some kind of quiz that would keep people from jamming 3.5mm phone plugs into the holes in RCA connectors, I would support that. 

  9. RJ-45 also implies a certain type of phone circuit is connected to the connector.

    Also I was annoyed that the F connector was just called “Coaxial RF connector”.  Do they not realize just how many RF connectors there are?
