Well, we all know USB stands for Universal Serial Bus.
It is named as so because it can be used to connect multiple products together either to charge or to transfer data.
What is USB? Types of USB and their differences
Some of the devices using USB are
- Hard Drives
- Webcams etc…
Well nowadays, we are using various devices to charge multiple digital devices.
Types of USB Ports.
Based on the physical shape of connectors, USB’s are classified into three types and they are
- USB Type-A
- USB Type B
- USB Type C
USB Type-A is the one end of USB cable which are rectangle in shape and mostly used to connect to computers and charging sockets.
USB Type B is the other end of USB cable which are connected to peripherals such as Mobiles, Printers, and Speakers etc…
USB Type B comes in different shapes based on peripheral connections. Such as square-shaped USB connector for printers, Micro USB for Mobiles etc…
USB Type C is the rounded rectangle-shaped port. It is having connectors inside the port both the sides. That means, we can connect USB Type C port in any direction.
Based on speed and power transmission, USB are classified into multiple versions such as USB 1.1, USB 2.0, USB 3.0 and USB 3.1
Each version has its own and different configurations as mentioned below
|USB 1.1||USB 2.0||USB 3.0||USB 3.1|
|Top Transfer Speed||12 Mbps||480 Mbps||5 Gbps||10 Gbps|
|Max Power||2.5V, 500mA||2.5V, 1.8A||5V, 1.8A||20V, 5A|
|Power Direction||Host to peripheral||Host to peripheral||Host to peripheral||Bi-Directional|
|Cable configuration||Type A to Type B||Type A to Type B||Type A to Type B||Both ends are Type C and are reverse plug orientation|
What is Host?
A host is a device which acts as a power station and transfers power via USB Cable. A host can be a computer, Charging Dock, Travel Charger etc…
What is Peripheral?
A Peripheral is a device which used the power drawn from Host to charge or to function. Some of the peripherals are Mobiles, Printers, webcams etc…
What is Port?
A port is a connecting space to connect USB ends to Host and Peripherals.
We can use all types of USB versions in all USB versions, but the transfer speed and power capacity will be the same as the low version of USB connection.
USB 3.0 connects to USB 2.0 Port, Then transfer speed will be max of 480 Mbps and power capacity of 2.5V and 1.8A.
Similarly, if USB 2.0 is connected to USB 3.0 Port, Then also transfer speed will be max of 480 Mbps and power capacity of 2.5V and 1.8A.
We recommend using the USB cables with same version ports to get better speed and for the long life of cables.
