What is USB?

USB is an acronym which stands for Universal Serial Bus. USB is very common today and is very popular for moving and copying files, specifically flash drive memory using USB port.

USB wires also function like those of the flash memory USB. The USB wire or the USB cord has four wires inside if you do the skinning. Get a knife or cutter and then you slice the USB wire. You can see four wires inside it.

A USB wire has four different colors and you can see them after you remove the rubber covering of the USB cord wire.

There are various set of wires of USB wire depending on the brand names you have.

In our photo example here, you can the wire colors. We have the colors red, black, green and white.

Other set of colors will be included for discussion below.

Now, the USB color code of our first picture here will be stated below.

Color Code of the four wires inside a USB

1. Red wire. Red wire of the USB is the five volt wire or the positive wire to power a device and it will be paired with its partner, the negative wire which is the black wire.

2. Black wire. Black wire is the ground wire or the negative wire. The red wire and black wire inside a USB is the electric power pathways of the USB in DC or direct current.

4. Green wire. The Green wire of the USB cord inside is the negative data wire or the negative minus. This wire is paired, of course, with the white wire.
