USB connectors come in different shapes and sizes, but the most commonly used types are:
USB-A: This is the standard USB connector found on most computers and USB hubs. It is a rectangular-shaped connector with four contacts. USB-A is usually used as a host port for connecting devices like flash drives, keyboards, mice, and external hard drives.
USB-B: This type of USB connector is commonly used on devices that are connected to a computer, like printers, scanners, and external hard drives. It has a squarish shape with either a rectangular or trapezoidal top section and is often larger than a USB-A connector.
USB-C: This is the newest type of USB connector, known for its small, oval shape and reversible design. It has a symmetrical connector that can be plugged in either way, eliminating the need to check for the correct orientation. USB-C is becoming increasingly popular and is found on many modern devices, including smartphones, tablets, laptops, and monitors. It supports higher data transfer speeds and can also carry power, video, and audio signals.
