What to do if you want to move information
from one flash drive to another, or to synchronize data on several external
devices, such as the desired USB ports are already occupied by the printer,
keyboard, mouse, camera, or USB modem? Disconnect all unnecessary at the
moment, the devices, and after the necessary actions to join again? It is uncomfortable,
tedious and harmful for your computer. To solve such problems and invented a
device called a USB hub or a USB hub. This article will talk about how to
choose the right USB hub for your needs.
Tablet USB hub (hub – hub) or the hub – a kind of
splitter ports, allowing you to extend the functionality of the computer by
increasing the number of externally connected devices equipped with interface
USB, an intermediary between your computer and USB devices. USB (universal
serial bus), as the name implies, was originally developed to enable
connectivity of all devices to the appropriate controller on a computer. Such a
controller is called a USB controller, it software control, and provides the
programming logic for communicating with external devices, the connection of
which is carried out using a special USB cable. This cable section has a few (2
to 6) copper spiral twisted pairs of copper wires (twisted pair) for
transmission and reception of data, and two wires to provide power to the
external device. If you hold a loose analogy, a USB hub is a road junction with
traffic controller by radio.
As mentioned above, a powered Micro USB hub provides connectivity between peripheral devices and a
computer. The interface itself was developed in 1994 and since then was divided
into several specifications. Since modern USB hubs have on your hull ports with
multiple specifications, to select a good device it is necessary to understand,
than they differ from each other. The specifications differ in the supported
data transfer speed, maximum current, which can give the controller the number
of connected devices.
