This article provides information about the communications aspects of Universal Serial Bus : Signaling, Protocols, Transactions. USB is an industry-standard used to specify cables, connectors, and protocols that are used for communication between electronic devices.
The Universal Serial Bus was developed to simplify and improve the interface between personal computers and peripheral devices, such as cell phones, computer accessories, and monitors, when compared with previously existing standard or ad hoc proprietary interfaces. [12]
Universal Serial Bus 4 (USB4), sometimes erroneously referred to as USB 4.0, is the most recent technical specification of the USB (Universal Serial Bus) data communication standard. The USB Implementers Forum originally announced USB4 in 2019. USB4 enables multiple devices to dynamically share a single high-speed data link.
The eXtensible Host Controller Interface (xHCI) is a technical specification that provides a detailed framework for the functioning of a computer's host controller for Universal Serial Bus (USB). Known alternately as the USB 3.0 host controller specification, xHCI is designed to be backward compatible, supporting a wide range of USB devices ...
A Universal Serial Bus, or a USB is an industry standard communication protocol used to communicate data across connectors, and cables from computers to peripheral devices and/or other computers. [4] WebUSB is a set of API calls that enable access to these hardware devices from web pages.
USB communications device class (or USB CDC) is a composite Universal Serial Bus device class. The communications device class is used for computer networking devices akin to a network card , providing an interface for transmitting Ethernet or ATM frames onto some physical media.
The USB Implementers Forum (USB-IF) is a nonprofit organization created to promote and maintain USB (Universal Serial Bus), a set of specifications and transmission procedures for a type of cable connection that has since become used widely for electronic equipment.
Serial AT Attachment, or SATA is designed and optimized for communication with mass storage devices. This usage is not universal, some definitions of peripheral bus include any bus that is not a system bus, including examples like PCI. [1] Others treat PCI and similar systems as a third category, the expansion bus. [clarification needed]
