What does USB stand for?

USB stands for Universal Serial Bus. This term reflects its function as a standard for connecting a wide variety of devices to computers and other peripherals. The main purpose of USB technology is to facilitate data transfer and provide power supply between devices. The design is intended to streamline the process of connecting different types of hardware without requiring the user to understand the technical details behind the connection types.

The term "Universal" emphasizes the widespread applicability of the standard across various types of devices, while "Serial" indicates that it communicates data one bit at a time (in a sequential manner). This has contributed to USB's popularity as a reliable and user-friendly method to connect numerous devices, ranging from keyboards and mice to external hard drives and cameras.

Other options, like Universal Service Bus or Unique Serial Bus, do not correctly represent the established terminology used in the industry, leading to confusion about the functionality and scope of USB technology. Universal Secure Bus is not a recognized term in the context of data transfer technology. Therefore, the correct designation of Universal Serial Bus clearly identifies its purpose and function in the realm of digital connectivity.
