All USB and USB C, USB 3.1, USB 3.2, USB4 Explained

USB (Universal Serial Bus) ports are the most common and easily recognizable PC connection ports in modern hardware. Your drawer may be filled with various types of USB cables, including Type A, Type B, Mini, and Micro versions, as well as the increasingly popular USB Type-C, commonly abbreviated as Type-C, USB-C, or USB C.

What is USB A?

In the mid-1990s, USB A, also known as USB-A or USB Type-A, began to gain popularity. This standard connector has a unique top and bottom, requiring proper alignment to insert.

What is USB B?

USB Type-B interfaces are relatively uncommon, but they have the same electrical characteristics as USB A interfaces. USB B interfaces are commonly used in printers and can also be found on some monitors and USB hubs.

What is Micro USB?

Micro-USB (and Mini-USB) is a smaller version of the USB interface. Due to its compact size, it has been an ideal choice for connecting and charging portable electronic devices since its introduction, such as power banks, e-readers, handheld GPS devices, and mobile phones.

What is USB C?

USB-C refers to the physical shape of the latest USB connector (note that the shape of the USB-C connector should not be confused with the speed of the data transfer standards, such as USB 3.1, USB 3.2, or USB4. This will be detailed later.)
