Computer cables (data cables) are somewhat similar to audio and video cables. Instead of transmitting sound or images, they send data for your computer to use. This can be anything from sending over a Word document to streaming movies and TV shows. Technically ethernet cables fall under this category, but ethernet is such a broad topic it needed its own independent article. Common types of data cables include:

  • USB
  • FireWire
  • Serial
  • DIN
  • PS/2

USB

USB is the most common type of data cable today, being found on computers, printers, hard drives, cell phones, and more. Along with transmitting data, USB is commonly used to recharge batteries on cell phones and other devices like video game controllers. There are several types of USB cables in various shapes and sizes. The two primary groups are USB 2.0 and USB 3.0.

USB 2.0 is capable of speeds up to 480 Mbps and comes in a few different varieties. When someone just says “USB”, they are generally referring to USB 2.0 Type A. These are the standard rectangle-shaped connections you can find on any computer. Next, there is Type B, which is also called a printer cable. Newer printers use this more square-shaped connection instead of older serial connections. Mini USB used to be used on cell phones but has mostly been replaced by Micro USB. You will still occasionally see it on other devices like digital cameras and GPS. Micro USB is still the standard on many Android phones but is starting to be replaced by USB 3.0 Type-C.
