The Universal Serial Bus (USB) is a standardized interface for connecting peripheral devices to a computer. It was first introduced in 1996 and has since become the most widely used interface for connecting devices such as keyboards, mice, printers, cameras, and external hard drives.
One of the key features of USB is its plug-and-play capability, which means that devices can be connected and disconnected without the need to restart the computer or reconfigure the system. USB devices are also hot-swappable, meaning that they can be connected or disconnected while the computer is running.
USB has evolved over the years and there are several versions of the interface, including USB 1.0, 2.0, 3.0, and 3.2. Each version offers increased speeds, improved power management, and additional capabilities.
The USB interface provides many benefits to users, including simplified setup and configuration of devices, ease of use, and increased compatibility with a wide range of devices.
