What does USB stand for?

USB stands for Universal Serial Bus. This term describes a standard for peripheral connection that enables computers and devices to communicate and supply power to each other through a single interface. Introduced in the mid-1990s, USB has become essential in connecting various devices, including keyboards, mice, printers, and external storage, facilitating both data transfer and electrical power.

The "Universal" aspect of USB highlights its widespread applicability across different types of devices and manufacturers. "Serial" indicates the method of data transmission, referring to the sequential sending of data bits, while "Bus" signifies a common pathway through which data can be communicated among multiple devices.

The other options do not accurately reflect the established meaning of USB or relate to any recognized technical standard within the field of computing. Understanding the accurate definition and function of USB is crucial for grasping how various devices interact in today's technology landscape.
