Ultimate Chart of Computer Connectors and Ports

Updated for 2020

The world of computers has a staggering array of cables, adapters, and ports in a variety of shapes, sizes, and colors. Most people don’t have to deal with these things on a daily basis, and one look at the back of your PC or the side of your laptop can sometimes be a bit confusing.

This handy chart is intended to help with that.

Not everything in the world is depicted here, but we’ve compiled a collection of all the common and/or major types. See anything that is incorrect, or think we should have included one you don’t see here? Drop us a comment below and we’ll make sure the next revision takes those into account. Thanks!

By the way, you can click on the image below to open a larger version where the descriptions are much easier to read.

    Thank you very much need all the help we can get these days. There is so much out there
    what ever happened to iso standard? LOL

  • Gord 04.13.2017 at 10:57 am

    I suggest indicating which connectors are legacy connectors (maybe with a different color in for the text?) Just to simplify what a person needs to be concerned with from 2017 on. Also consider adding lightning connectors.

    • Phil Rice 09.28.2017 at 2:05 pm

      Hi Catherine, I sent you an email with links to a high res version of the image that should work better for enlarged print quality. Thanks!

          Hi Erwan, The high res links are now in the body of the post itself. Thanks!

          • Sheldon 02.23.2020 at 11:03 am

            The hi res links are a fail. You see a winding progress indicator which simply does not go away.

            I have tried all three repeatedly, with the same result every time.

            I can see that it has been a few years, but sure hope someone will
            look into it.

          • Sheldon 02.23.2020 at 11:08 am

            My apologies. Just tried the TIFF link again, and it worked very quickly.

            Very nice graphic.

            Tufte would have smiled to see it.

          • Phil Rice 02.27.2020 at 6:09 pm

            Glad the download worked for you, Sheldon. Must have been a temporary glitch with Dropbox. Thank you!

  • Jun 10.05.2017 at 8:13 pm

  • Kevin 01.16.2018 at 5:47 am

    I came across your picture on pin interest. I’ve never seen one like it before and as soon as I saw it realised how incredibly helpful it is. My study is full of about 100 connectors kept over the years for different pieces of video and IT equipment – I think I have an example of every one of these!!

    At last I can sort them and decide which to keep and which to junk!

  • John 01.16.2018 at 7:46 am

    Please send me the hi-res link.

    Thanks so much!

  • Lila Alevizaki 01.30.2018 at 4:38 am

    Hi, High resolution image pleeeease

  • John Pleasants 02.01.2018 at 1:46 pm

    I would love a Hi Res. version for my new STEM class room.
    If there are large ready made prints available I can certainly compensate.

    Thank you
    John Pleasants

    I’d like a link to the hi-res version of this great poster.

    Maybe you could make that link public here in the comments.

    Thank you!

  • Mary 05.11.2018 at 12:55 pm

    Hi Phil: Do you sell the high resolution version? I’m a beginning IT student and this is incredibly helpful, as well as saving much newbie humiliation 🙂 Thank you!

  • Phil Rice 05.15.2018 at 4:27 pm

    Ok, whew! I think I’ve got the links sent to everyone who asked for them. For anyone who asks from now on… check the bottom of the post, the high-res links are right there for you too. Enjoy!

    We are currently testing a printed poster version of this which may be made available for sale, for those who would like to have it delivered ready to hang. If you’re interested in this, let me know in the comments and I’ll make sure you are notified first when this is ready. (I’m thinking end of May 2018.) Thank you for your support!

  • John Small Berries 02.01.2019 at 1:25 pm

    Suggestion for future revisions: You’ve got the DB15 MIDI/Game port introduced in the Sound Blaster, but not the standard 5-pin MIDI port offered by a number of other sound cards (and the vast array of MIDI musical equipment – even most of the devices that implement MIDI over USB also have standard MIDI ports for compatibility with other dedicated MIDI devices).

  • David 05.08.2019 at 2:35 pm

    Hello! I love this chart, I have it hung in my office so that when people come to me to ask about cables I can ask them to point it out for me. (It’s sounds childish, but it seems to be working wonderfully)
    Thanks for this, I hope you keep updating it yearly when new ports become available.

  • Sovanny 06.20.2019 at 7:50 am

    How can i buy ultimate chart of Computer connectors and Ports with the cheap price.

    • Phil Rice 06.20.2019 at 5:40 pm

      Hi Sovanny, you can either purchase the poster from us on our website, or you can download the high res images from this page for free and get it printed somewhere yourself (local printer, VistaPrint, etc.).
