USB (Universal Serial Bus) connectors are used to connect any type of device to a computer. They come in a variety of shapes and sizes. The most common type is the USB-A connector, which is a rectangular shape with four pins. This type of connector is found on computers, printers, external hard drives, and many other devices. There is also the USB-B connector, which is square-shaped and has seven pins. This type is mostly used for printers and scanners. The USB-C connector is the latest version, which is reversible and can carry a larger amount of data. It is used in laptops, tablets, and newer smartphones.
