USB

The USB port provides a single connection for multiple devices.
The icon was developed in 1995 and soon appeared as tattoos for ‘nerd’ and ‘geek’.
The design was inspired by Neptune’s Trident (Dreizack) -a three-pronged spear like Lord Shiva’s Thrishula.
Instead of points at the tips the symbol ends with a circle, triangle and square.
The different shapes represent attachment options.
This powerful design is a symbol of universal connectivity.
