USB

Also known as Universal Serial Bus

thumb|USB 80 Gbit/s port logo Universal Serial Bus (USB) is an industry standard, developed by USB Implementers Forum (USB-IF), for digital data transmission and power delivery between many types of electronics. It specifies the architecture, in particular the physical interfaces, and communication protocols to and from hosts, such as personal computers, to and from peripheral devices, e.g. displays, keyboards, and mass storage devices, and to and from intermediate hubs, which multiply the number of a host's ports.

AI overview

Universal Serial Bus (USB) is an industry standard that allows different types of electronic devices—like computers, keyboards, displays, and storage devices—to connect together and share data and power. It works by specifying the physical connectors and communication rules that these devices need to follow so they can reliably talk to each other and be powered through a single standard connection type.

Introduced in 1996, USB was originally designed to standardize the connection of peripherals to computers, replacing various interfaces such as serial ports, parallel ports, game ports, and Apple Desktop Bus (ADB) ports. Early versions of USB became commonplace on a wide range of devices, such as keyboards, mice, cameras, printers, scanners, flash drives, smartphones, game consoles, and power banks. USB has since evolved into a standard to replace virtually all common ports on computers, mobile devices, peripherals, power supplies, and manifold other small electronics.
