3. What’s the difference between USB and USB-C?

USB, or Universal Serial Bus, is a standard that defines the cables, connectors and protocols used to connect, communicate and supply power between computers and electronic devices. There are several types of USB connector, including Type A, Type B, Mini, USB Micro, and more recently, USB Type-C, or USB-C.

  1. USB Type A: This is the most commonly used USB connector. It is flat and rectangular, and is often found on computers, games consoles, televisions, etc.
  2. USB Type B: These are square and are mainly used to connect printers and scanners to computers.
    USB Mini and Micro: These are smaller than USB Type A and B, and are often used to charge mobile devices such as smartphones and tablets.
  3. USB Type-C: USB-C is a newer, more advanced version of the USB standard. It has a reversible design, meaning you can plug it in either direction, which is not the case with other types of USB connectors. What’s more, USB-C can support higher data transfer speeds (up to 10 Gbps with USB 3.1) and higher output power (up to 100W), making it capable of charging larger devices such as laptops.USB-C also supports several protocols such as HDMI, DisplayPort, and Thunderbolt 3, meaning that with the right adapters, it can be used to connect a variety of different devices.
