What is USB?
USB – Universal Serial Bus is a very basic connection port on devices such as laptops, desktops, … they are commonly used to connect these devices to a number of other accessories such as: : keyboard, mouse,…
There are several types of USB standards that are widely used today such as: USB 2.0, USB 3.0, USB 3.1. In addition, there is USB 1.1, but this connection standard is no longer commonly used and has been replaced by more modern connection types.
Features of USB
USB is a type of communication port, allowing devices equipped with this type of port to be connected to each other without having to use the internet or a third-party transmission line. Users can transfer data (audio, video, etc.) from one device to another through the USB port.
Besides, the USB port is also capable of transferring power from the power supply to the power needed to operate. Users can supply power from the laptop to a number of devices such as phones, heat sinks, … through this connection port.
Today’s popular USB standards
USB 2.0
USB 2.0 is considered the second generation of USB 1.1 with speeds up to 50 times faster. In particular, this USB 2.0 version is well compatible with previous USB 1.1 devices, both software and hardware, thanks to the support of three main speeds of 1.5 Mbps, 12 Mbps, 480 Mbps.
Currently, manufacturers have released USB 3.0, 3.1, 3.2 and higher USB 4.0 standards, but the USB 2.0 standard has always been applied with at least 2 ports and more than 4 ports (2 before – 2 later) to connect to basic devices such as a keyboard or mouse.

USB-A 3.0, 3.1
USB 3.0 is the third major version of the Universal Serial Bus (USB) standard, equipped with a new data transfer acceleration technology called SuperSpeed USB (SS) that makes it possible to transfer data at high speeds. up to 5 Gbit/s .
USB 3.0 allows better connection of computers and electronic devices. If converted to a capacity value for easy visualization, the number means that USB 3.0’s write speed is up to 625 MB/s , 10 times faster than the USB 2.0 standard.
For USB 3.1, currently this connection standard is divided into 2 versions:
- USB 3.1 gen 1: is actually just another name for the USB 3.0 standard, they keep the same parameters as on the 3.0 standard and improve slightly in performance but not too significantly.
- USB 3.1 Gen 2 : this is a big upgrade over Gen 1. This USB standard can support data transfer at 10 GB/s (theoretical specification). In actual use, the data transfer rate achieved by this connection standard is about 1.2 GB/s .
USB-C
USB-C is a form of USB connection port, they came after USB-A and USB-B . First, we need to clearly distinguish the concept of USB-C which is the regulation of the shape of the connection port, and the USB 3.0 or 3.1 standard which is the regulation of data transmission speed .
Most current USB-C types use the 3.1 standard , providing stable connectivity and better transmission speed. This type of connection port possesses many advantages such as: compactness, image transfer support (USB A and USB B are not available), easy connection.
Currently, USB-C has been widely used on most electronic devices such as smartphones, laptops, and tablets. Besides, the ability to transfer power up to 100W also helps this type of port to be used to charge devices faster.
USB-C is gradually being popular on all devices and this type of port can completely replace previous connection ports such as: HDMI, VGA, USB-type A, DisplayPort, charging port, …
