USB hubs have become popular in particular with laptops and different computers. With the need for devices that require a USB connection, the USB hubs have emerged very usefully. These hubs provide extra USB ports for other cables (like- USB to HDMI adapters) to a setup. Hubs are the USB version of a standard extension lead plug, transforming one USB socket into a USB hub. These are plugged in the computer or laptops, and the additional ports that come with a USB hub are used to connect keyboards, mice, and other like devices.
Technology and Specification of USB hubs
The Universal Serial Bus hub, also termed an upstream port, hosts other devices or connections. The hubs are usually transparent for the system and are not visible on system mapping. The host hub broadcasts the data received or sent from the upstream port to the downstream ports, yet the data collected from the downstream port is signalled to just the host and the upstream port.
With further advancement in technology, the intelligent USB hubs (including type c HDMI cable) can be connected to the PC or laptop via USB 3.0 or USB-C. Several USB ports range from 4 USB 3.0 ports to 7 USB 3.0 ports, along with backward compatibility of USB 2.0 and USB 1.1 in some. The transported data is rated up to five GBPS along with the support of hot-swapping. The difference arises when the USB port hub is 3.0 rather than being USB 2.0, as the former transfers files or data much faster than the latter.
