What type of interface does USB provide?

USB, or Universal Serial Bus, is designed as a standard for communication between various devices and host controllers, facilitating data transfer and power supply among a wide range of electronic devices. This includes peripherals like keyboards, mice, printers, and external storage devices connecting to computers or other host systems. The USB interface standardizes the way these devices communicate, ensuring compatibility and ease of use.

The role of USB in establishing communication is crucial; it acts as a bridge, allowing devices to send and receive data reliably and efficiently. The protocol defines both the electrical and physical standards for the communication process, ensuring that devices can interact seamlessly with the host controller, regardless of the manufacturer.

In contrast, other options refer to different contexts. Audio and video communication applies to technologies like HDMI or analog audio connectors, which are distinct from the general purpose of USB. The connection between network devices typically pertains to networking protocols and interfaces, such as Ethernet, which focus on network interoperability rather than direct device communication. Data transmission over fiber optics involves a specific medium for high-speed data transfer that is fundamentally different from the copper or plastic connectors and protocols used in USB technology.
