Ultimate Chart of Computer Connectors and Ports

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.

    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 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!

  • 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

    Hi Phil,

    Thank you for this clear and structured version of most of connectors.
