Initially, the USB interface was developed forconnection of telecommunication 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 solve this issue, you can disconnect the unclaimed device for a while, and thus release the connector, or you can use a special device, such as a USB splitter.
This inexpensive device is a device that has two or more ports. USB splitter connected to the free connector of thecomputer. 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 concentrators. Let's consider each of them.
This USB hub connects tomotherboard PC through a free slot type PCI. If the user is not familiar with the device of the computer, then such an installation itself is not recommended. The advantage of this hub is the ability to install a new version of the 3.0 interface on a PC if it supported versions 1.0, 1.1 or 2.0. True, you should update the software.
This type of device is inexpensive and simpledevice. 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.
This device is also connected to a freeport of the PC. 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.
These USB splitters are ideal forlaptops. The specified devices are connected to a dedicated port 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.
