If you've ever looked closely at the USB ports on your computer, motherboard, or docking station, you might've noticed they're not all the same color. Black, blue, teal... and sometimes, bright red.

USB ports began development in 1994 with the goal of creating a universal connector to replace the multiple standards used in computers of the time. Since then, USB ports have evolved significantly.

One piece of technology that's hard to avoid every day, besides your phone, is a USB port. They're everywhere -- on your laptop, phone, tablet, PlayStation, or even in your car or on your couch.
