The number of devices that use USB technology is growing. And in the event that there are not enough USB ports for all devices, you can purchase a USB hub.
What is a USB hub
USB technology, which was invented to connect computing and telecommunications devices, is now the primary means for connecting many gadgets. Their number is simply surprising - these are keyboards, mice, modems, coolers, external hard drives, printers, flash drives, even coffee makers and lamps. And since all these devices need to be connected to a computer, there is currently a trite lack of USB ports.
There are two ways to solve this problem. The easiest way is to connect only those devices that are needed at the moment, and disconnect unused devices, thereby freeing up USB ports. And the second way is to purchase an original device called a USB hub (USB hub).
A USB hub is a small device that has multiple USB ports. It connects to one of the computer's USB ports (thus taking up only one USB connector), and makes it possible to use multiple USB devices. Thus, a USB hub increases the number of USB connectors on your computer, reduces wear and tear, and makes it easier to use multiple devices.
Types of USB hubs
There are four types of USB hubs. The first is a USB PCI card that plugs into a PCI slot on the motherboard. To do this, you will have to open the system unit, and if you do not understand this, then it is better not to use this type of USB hub.
The second kind is a non-powered USB hub. This simple device plugs into one of your computer's external USB ports. After that, it will be possible to connect to it any other devices. These USB hubs are very compact and are great for both computers and laptops. But they have a small drawback. Some USB devices (printer, digital camera, scanner, etc.) need power supply, and this type of hub will not be able to provide them with the required amount of electricity, especially if several devices are connected at once.
The third type is a powered USB hub. It is also very compact and plugs into your computer's external USB port. In addition, this USB hub can be plugged directly into a power outlet. This makes it possible to connect any kind of USB devices to it.
And the fourth kind is a USB computer card. If you use a laptop in your work, and you also need to constantly move with it, then just such a USB card will be an excellent alternative to a USB hub. It connects to a USB port on the side of the laptop and allows you to connect two more additional devices.
