Amazon Basics USB 2.0 A-Male to Micro B Cable For Smartphone, 6 feet, Black

Product Information

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.

The USB Type-A connector is fully backwards compatible with all generations of USB Type-A plug, from 1. The throughput of each USB port is determined by the slower speed of either the USB port or the USB device connected to the port.Thus, to support SuperSpeed data transmission, cables contain twice as many wires and are larger in diameter. However, some of this directed topology is lost with the advent of multi-purpose USB connections (such as USB On-The-Go in smartphones, and USB-powered Wi-Fi routers), which require A-to-A, B-to-B, and sometimes Y/splitter cables. Compliant devices must either fit within the size restrictions or support a compliant extension cable that does.

In reality, all types can be high-quality or low-quality, depending on the quality of their engineering and the application. The mini and micro formats may connect to an AB receptacle, which accepts either an A or a B plug, that plug determining the behavior of the receptacle.The goal was to make it fundamentally easier to connect external devices to PCs by replacing the multitude of connectors at the back of PCs, addressing the usability issues of existing interfaces, and simplifying software configuration of all devices connected to USB, as well as permitting greater data transfer rates for external devices and Plug and Play features. A composite device may provide several functions, for example, a webcam (video device function) with a built-in microphone (audio device function). With the release of the USB Type-C specification in 2014 and its 3A power capability, the USB-IF elected to increase the upper voltage limit to 5.

Various protocol converters are available that convert USB data signals to and from other communications standards. While not compliant with the USB standards, these cables at least do not provide a device damage hazard since Type-B ports on devices are unpowered by default. The Micro connector is also designed to reduce the mechanical wear on the device; instead, the easier-to-replace cable is designed to bear the mechanical wear of connection and disconnection. However, USB has the advantage of allowing hot-swapping, making it useful for mobile peripherals, including drives of various kinds.Original Thunderbolt implementations have two channels, each with a transfer speed of 10Gbit/s, resulting in an aggregate unidirectional bandwidth of 20Gbit/s. Class 2 support enables much higher sample rates such as PCM 24 bit / 384 kHz and DSD (DoP) up through DSD256.
