Types of USB Ports and connectors


USB Ports

Nowadays, there are different types, sizes, and shapes of USB ports and connectors. On computers, laptops, or tablets, you can find at least one USB port. The following different types of USB connectors can carry high power and data.


Types of Connectors

In the beginning, when technology comes into existence, there were only two types of connectors, standard A and standard B. Now, there are many different devices and peripherals that are available, but still, they do with A and B connector interfaces.  


USB-A

USB Type-A connector is known as a standard-A connector. It is the most recognized and commonly used connector for desktops, laptops, notebooks, and tablets. It supports almost every USB version, like USB 3.0, USB 2.0, and USB 1.1.

USB-B

Users can connect printers, scanners, and other external hard drives to computers using USB-B Types of connectors. It has two different configurations, one is 1.1 and 2.0-speed protocols, and the other is 3.0 and later spec. Most of the USB application uses two connector type scheme, like type-B to type-A cable.  


USB-B-Mini

Mini USB is smaller than standard USB. It has five pins, while the standard USB has four pins. The Mini USB connection is usually used by portable electronics such as mp3 players and cameras with 1.1 and 2.0 speeds. There are both four-pin and five-pin versions of the Mini-B connector.

USB-B- Micro


Micro USB is a minimized version of the USB. Design Micro USB aims to replace Mini-USB, so it is thinner than mini USB. It has five pins, and all of them are inoperative modes.

Gigabit per second (symbol Gbit/s or Gb/s, often abbreviated "Gbps") is a unit of data transfer rate equal to 1,000 megabits per second. 1,000,000 kilobits per second. 1,000,000,000 bits per second. 125,000,000 bytes per second


Mbit/s Megabit per second

Megabit per second (symbol Mbit/s or Mb/s, often abbreviated "Mbps") is a unit of data transfer rate equal to 1,000 kilobits per second. 1,000,000 bits per second. 125 kilobytes per second.
