What Is a USB?


Universal Serial Bus (USB) is a standard technology used to connect peripheral devices to computers.

Its plug-and-play feature allows devices like keyboards, mice, printers, or external hard drives to interface and exchange data with a computer without installing additional software.

USB also delivers power to connected devices and is commonly used to charge phones, cameras, and other portable gadgets.

There are several versions of USB connectors and USB port types, each with different transfer speeds and power delivery capabilities. USB Type-C, introduced in 2014, is becoming a cross-industry standard for electronic devices due to its efficient transfer rates, reversible design, and user preference.
