How USB Ports Work

The USB is a method of connecting peripheral devices to a computer so that they can be used easily.  This method is far superior to older methods, as the ease of connection is so much better with the USB port.  The speed at which data can be transferred has been improved greatly as well.  The USB allows for a device to be identified as soon as it is plugged in.  With other methods, you had to attach a device while the computer was off.  USB ports have become one of the most common methods for connecting peripheral devices.

To realize how convenient the USB port is, we need to go back to the old ways.  Printers were connected to printer ports, and there was usually only one of these.  This is also the same spot that you would need to plug your Zip drive into, or any gadget that required high-speed.  Modems and many other devices plugged into the serial port.  If you were lucky, you had two.  If you only had one, chances are you needed it for the modem.  Devices needing faster speed came with their own card.  These had to go into a card slot inside the computer case.  The number of card slots was limited, so you had to pick and choose your devices wisely.  We won’t even talk about having to install the software for the cards.  The USB came in to help stop these headaches and seemingly grueling activities.   You can now connect up to approximately 127 devices to your computer with one simple, standardized method, making customised USB devices extremely popular.

When you plug a customised USB device into a USB port, the computer operating system searches for the device in its drivers.  If the driver is not found, the appropriate one must be installed.  The computer will be able to recognize the device the next time that it is hooked to the computer.  When the device is recognized and loaded to the correct driver, data is transferred between the computer and the devices at a very high rate of speed.  Files can be transferred to and from hard drives, USB flash drives and other storage devices.

USB has been a great time and sanity saver for any computer user.  People seem to be more on the go these days, and the quicker ways of the USB make it possible to travel, and to be a lot more mobile with your operating systems, programs and information.

Not only can you run many more devices with USB ports, you save a lot of space on your computer as well.  There is also not as much wear and tear on your hard drive. Not everything has to be stored and formatted like the old days, and customised USB devices are adding an extra dimension of fun to data storage with numerous fantastic designs available.

As you sit and use your separate keyboard, scanner, printer and more with your portable laptop, you have your USB set up to thank.   The world of computers is much more convenient due to the production and function of the USB port.
