What interfaces does the usb hub have?
Currently, there are docking stations on the market with varying numbers of interfaces from two to 12. These ports cover charging, audio, USB, HDMI, SD card, network port and other functions, and multiple interfaces can be used at the same time without affecting each other. Generally speaking, nine ports can basically meet daily office needs.

1. USB3.0: Expand peripherals
Mainly realizes the need to transfer data between U disks and mobile hard disks, as well as connect mice, keyboards, and MacBook mouse buttons.
2. USB2.0: data transmission
The maximum transfer rate of USB2.0 is 480Mbps, which is 60MB/s. However, in most cases, the maximum actual transmission speed of usb2.0 is only 30MB/s.
3. Type-C interface
Supports data transmission from mobile phones, hard drives, disks, etc. Now the speed of USB 3.1 Gen2 has reached 10Gbps, and the design standards can also meet the transmission of both video and data.
Applicable to Apple Macbook, Huawei Mate Book, Xiaomi notebook, Huawei P40, Mate30, Samsung S20, S10 series mobile phones.
It should be noted that USB 3.1 Gen1 is USB 3.0, and USB 3.1 Gen2 is the real USB3.1.
4. USB-A: connect keyboard and mouse
The USB-A port is also used to connect the keyboard and mouse, because the keyboard and mouse have very low performance requirements for the interface.
So regarding the connection of keyboard and mouse, you only need to pay attention to whether the number of interfaces is enough when purchasing. Don’t worry about performance issues.
5. Thunderbolt interface
The interface uses Thunderbolt technology and meets both PCI Express and DisplayPort communication protocols.
Among them, PCI Express is used for data transmission, DisplayPort (also known as DP interface) ultra-high-definition video and up to eight-channel audio.
Thunderbolt 3 interface, 40Gbps theoretical transmission rate. Only when the host port, connecting cable, and terminal equipment comply with lightning specifications can the best transmission performance be achieved.
It is often used on notebooks, and notebooks with this interface are more compatible with the docking station! However, products that support Thunderbolt 3 are currently very expensive.
6. HDMI: external large screen
The current mainstream versions are HDMI1.2, HDMI1.4, and HDMI2.0. Different interfaces support different resolutions, color depths, and refresh rates.
The HDMI interface is an interface used to transmit image and sound signals. It is common in smart TVs, set-top boxes, projectors and other equipment. Its interface is in the shape of an inverted trapezoid. In business, projectors/monitors are used for meetings, PPT presentations, etc., and a corresponding HDMI cable is required to achieve screen projection.
The HDMI interface was proposed in 2002. With the development of the industry, the HDMI 2.1 standard has been able to support 4K@120Hz and 8K@60Hz, supports high dynamic range imaging (HDR), can be optimized for scenes or frame numbers, and is backward compatible with HDMI 2.0, HDMI 1.4. The most important thing is that it transmits video and audio simultaneously.
