USB splitter: purpose, description, types of devices

Initially, the USB interface was designed to connect telecommunications and computer equipment. However, gradually it became the main type that connects most devices, for example, keyboards, computer mice, modems, external hard drives, lamps, coolers and even coffee machines. Most peripherals now connect to a personal computer via a USB interface. As a result, there was such a problem as the lack of free ports. To resolve this issue, you can temporarily disconnect an unclaimed device, and thus release the connector, or you can use a special device, such as a USB splitter.

What is a hub?

This inexpensive device is a device that has two or more ports. USB splitter Is connected to the free connector of the personal computer. It enables the use of more devices through this type of interface. The advantages of such devices include reducing wear on the main port of a personal computer. There are four types of hubs. Let's consider each of them.

Internal card of the computer's system board (USB PCI)

This USB hub connects to the PC motherboard via a free PCI slot. If the user is not familiar with the computer device, then such an installation is not recommended. The advantage of this hub is the ability to install a new version of the 3.0 interface on the PC if it supported versions 1.0, 1.1 or 2.0. True, you should update the software.

External non-powered USB splitter

This type of device is an inexpensive and simple device. It connects directly to the port of the personal computer. No settings are provided, the hub is immediately ready for use. Such devices, as a rule, are very compact and ideally suited to the owners of portable and stationary computers. However, you should be aware that some peripheral devices connected to the USB interface require power through this connector. For example, scanners, printers, digital cameras and stuff. This type of hub is not able to provide power to external devices, especially if several devices of this type are connected at once.

External powered USB hub

This device also connects to an idle PC port. The difference lies in the built-in or external power supply from the 220V network. Through it the peripheral devices connected to the concentrator are powered.

External computer USB-card

These USB splitters are ideal for laptops. These devices are connected to a dedicated port, which is located on the side panel of the laptop. Such a hub is capable of providing two additional USB connectors. If the connector is in the back of the computer, then it is advisable to purchase an extension cord. This will place the hub in a user-friendly location.
