How secure and stable is the 12-in-1 Type C Hub during data transmission? Is there any data error correction or protection mechanism?

Generally speaking, the working principle of a hub is to broadcast the received data to all connected ports, regardless of the address of the target device. This broadcast nature may bring some potential problems.
In terms of security, since the hub does not have the ability to identify the target computer, it will send user data packets to all nodes, which is likely to bring insecurity to data communication, because some people with ulterior motives may easily illegally intercept other people's data packets.
In terms of stability, when multiple devices communicate at the same time, the communication between them may conflict, resulting in a decrease in network performance. Especially in the case of large network traffic, the hub may be congested, which in turn affects the stability of data transmission.
However, some more advanced hubs may have certain data error correction or protection mechanisms to improve the reliability of data transmission. For example, they may use some signal processing technology to reduce the impact of signal attenuation and interference on data, or have certain error detection and correction capabilities to try to correct data errors when they are found.
But in general, hubs are relatively weak in terms of the security and stability of data transmission. In contrast, a switch is a smarter device that can send data packets only to the devices that need to receive it based on the MAC address of the target device, thereby reducing redundant data traffic on the network, reducing the possibility of conflicts, and generally performing better in terms of security and stability.
If you have high requirements for the security and stability of data transmission, it is recommended to consider using a switch to build a network. Of course, the specific security and stability will also be affected by a variety of factors such as the brand, quality, design of the hub, and the connected devices and network environment. In practical applications, the overall performance and stability of the network can be improved by reasonably planning the network topology, controlling the number of devices in the network, and avoiding excessive broadcast data. At the same time, take appropriate network security measures, such as encrypted communication, access control, etc., to enhance the security of data transmission.
