Understanding USB Connectors

USB, which stands for Universal Serial Bus, is a standard for connecting computers and other devices. Most of us are familiar with the common rectangular connector we use to charge our phones or connect peripherals. However, there are multiple types of USB connectors, with USB A and USB B being the most common.

What Is USB A?

USB A connectors are what most people think of when they hear “USB.” They are typically rectangular in shape and are often found on computers, laptops, and wall chargers. USB A ports are used to connect devices like flash drives, keyboards, and mice.

For example, consider a freelance graphic designer, Sarah, who uses a USB A flash drive to transfer high-resolution images for her clients. For Sarah, having the right USB A flash drive is critical to her workflow, allowing her to quickly transfer files without hassle.

What Is USB B?

USB B connectors are square and usually found on larger devices like printers and scanners. They are not typically used for connecting peripherals directly to computers but rather for connecting devices to a computer or power source. USB B connectors can come in a couple of variations, including mini and micro USB B, commonly used in smaller devices.

For instance, Mike runs a small print shop and frequently uses a USB B cable to connect his printer to the computer. The USB B connection ensures that high-quality images are transmitted for printing, but he sometimes struggles to find compatible cables. This pain point often leads to delays in his order fulfillment.
