The full form of USB is Universal Serial Bus (USB). Originally designed to connect computers and telecommunication equipment, it has slowly become the main means of connecting a whole host of other devices and has contributed significantly to today’s IT world.

The large number of USB products on the market today is just stunning, from mice and keyboards, modems, external hard drives to USB fans, light heaters and coffee cups! Most external devices connected to your computer connect today to a computer through a USB port. So, no wonder that before most, most computer users are wondering what to do when the USB ports (sockets) on their computer are all used.

There are two solutions to the problem, connect and disconnect the connectors constantly when you change USB devices or invest in a simple and inexpensive device called USB Hub.

A USB Hub is a small unit with two or more USB ports that connect to a USB port on your computer, allowing you to connect multiple USB devices without disconnecting others.

Extending the number of USB ports on your computer in this way not only saves the USB ports and connectors but also ends up with all those who struggle behind your PC! Generally, there are four available types:

1. Internal USB PCI Card

A PCI USB internal card must be installed by opening the PC case and inserting a card into a vacant PCI slot on the motherboard, this type of USB expansion is only recommended if you are familiar with working with and inside computers. If you have older USB1.1 and upgrade to USB2.0, your version of Windows will need to be updated so your PC can support USB2.0 functionality.

2. USB Hub (Powered)

An external, non-powered USB Hub is an inexpensive and simple device that connects directly to one of the existing USB ports on your computer, and that’s all there is. These are usually very compact and thus make ideal solutions for mobile phone users with laptops and desktop users.

Note that some USB devices require a small amount of power through the USB port, usually mechanical devices such as printers, scanners, digital cameras, and so on. This type of USB hub may not be able to provide a proper power to these devices, especially if you use some USB devices together.

3. Powered USB Hub

A USB external hub is also compact and connects directly to one of the existing USB ports on your computer, so again you do not have to open your computer to install it. The only difference is that the powered Hub comes with a separate power supply that needs to be connected to the power outlet, feeding all the USB ports on the hub, allowing the proper operation of any type of USB device.

Most Hubs are delivered with a sensitive length of the USB cable, allowing the Hub to position itself in a more accessible place, on the top of your computer or on the desk, making it easier to connect and disconnect USB devices. This makes Hub Hub the best solution for all desktop computer users.

4. USB PC Card

If you are using a laptop and you are moving, you have an extra choice for the USB hub, the USB PC card, also known as the PCMCIA USB card. This device is inserted into the PCMCIA slot/port on the side of the laptop and instantly offers two additional USB ports without using any of the existing USB ports on your laptop.
