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 peripheral devices today connect to a personal computer via a USB interface. As a result, a problem such as a lack of free ports arose. To solve 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 (hub)?
This low-cost device is a device that has two or more ports. USB splitter plugs into a free slot on a personal computer. It makes it possible to use more devices through this type of interface. The advantages of such devices include reduced wear on the main port of a personal computer. There are four types of hubs. Let's consider each of them.
Internal computer system board card (USB PCI)
This USB hub is connected to the PC motherboard via an available PCI slot. If the user is not familiar with the computer device, then such an installation is not recommended to be carried out independently. The advantage of the mentioned hub is the ability to install a new version of the interface 3.0 on the PC if it supports versions 1.0, 1.1 or 2.0. True, you should update the software.
External non-powered USB hub
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 owners of portable and stationary computers. However, you should be aware that some peripherals connected to the USB interface require power through such a connector. For example, scanners, printers, digital cameras and more. 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 splitter
This device also connects to a free PC port. The difference lies in the built-in or external power supply from the 220V network. Through it, peripheral devices connected to the hub are powered.
External computer USB card
These USB hubs are ideal for laptops. These devices are connected to a dedicated port, which is located on the side of the laptop. Such a hub is able to provide two additional USB connectors. If the connector is located on the back of the computer, then it is advisable to purchase an extension cord. This will allow you to place the concentrator in a place convenient for the user.
