Type-A

All cables have type-A connectors on one side; all peripheral devices (such as keyboards, mouse) have type-A connectors on one side; and a personal computer usually has multiple Type-A ports; in other devices and power adapters, type-A ports are used for data transfer and charging. 

Type-B

This connector looks almost square and connects printers and other power devices to computers. It is not as widespread as the type-A connector.

Mini-USB

The Mini-USB was the standard connector type for mobile devices when the micro-USB connector type was unavailable.

As we know from its name, mini USB is smaller in size when compared to regular USB and is used in cameras with non-standard connector types.

Micro-USB

These are used in today’s generation and other portable devices; standard USB cable is used in all types except in Apple. 

Type-C

This is a reversible cable which has a higher transfer rate and is more power compared to other USB types; because of its brilliant features, this is used in standard laptops, desktops, tablets, and smartphones.

Who Invented USB?
