What is usb meaning?

The Universal Serial Bus (USB) is a standard cable interface that allows communication between devices, including computers, smartphones, cameras, and external storage drives. It was first introduced in 1996 as a replacement for the older serial and parallel ports. USB is a plug-and-play interface, which means it automatically detects and configures devices without requiring any software installation or configuration. It is a bi-directional communication interface that allows data to be transferred between devices at high speeds. There are different types of USB connectors, including Type-A, Type-B, Micro-USB, Mini-USB, and Type-C. USB has become the most popular data transfer and charging standard globally, and almost all modern devices include USB ports.
