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!
You can click on the image below to open a larger version where the descriptions are much easier to read.

I would like to make this into a poster for my classroom. I teach computer maintenance & networking. Is that possible? What would the size be? Thanks
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
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.
i will like to know more about this conection coz. i use more tyme on using computer
I also would like to make it into a large poster. Has anyone succeeded in doing this? When I enlarge it the words are not legible.
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 Phil – can I also have a link to the high-res version of the image to print off a large copy.
Thank you,
Hi Phil, I would like one have the link as well please. Thanks in advance.
May I have a high res version as well?
Please send me an email high res link too.
Thanks
Hi Erwan, The high res links are now in the body of the post itself. Thanks!
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.
My apologies. Just tried the TIFF link again, and it worked very quickly.
Very nice graphic.
Tufte would have smiled to see it.
Glad the download worked for you, Sheldon. Must have been a temporary glitch with Dropbox. Thank you!
Hi Phil,
Can I also Get a high res version of this for my computer class? Many Thanks in advance.

Nice infographics…hats off
Can I also get to download a better images?, thanks..
Please may have an improved image download. Many thanks.
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!
Please send me the hi-res link.
Thanks so much!

Thank you

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!
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!
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).
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.
How can i buy ultimate chart of Computer connectors and Ports with the cheap price.
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.).
Hi Phil – can I also have a link to the high-res version of the image to print off a large copy.
Thank you,
Hi Rudi, the links to the high-res versions of the image are now part of the blog post itself, right at the bottom of the post (before the comments section). Best regards!
I need the following type of cable: USB 2.0 Type-A male to USB 2.0 Type-C male.
Hi David, I believe this is the cable you are looking for: https://www.amazon.com/AmazonBasics-Double-Braided-Nylon-Type-C/dp/B07D7TXTPP/
Hi
Thank you for this beautiful chart.
May you add GPIB interface (IEEE 488) general purpose interface bus.
I am organizing a course on IT fundamentals and would like to use the chart within my presentation. How do I go about requesting rights to use the chart solely for educational purposes?
