USB Connectors-Tips and How they Work
USB has come quite a long way since its conception in the year 1995, and it was initially designed to simplify how the users controlled peripherals and transferred data. Before its creation, the main interfaces used were parallel and serial connectors, both using different protocols to transfer data and control peripherals. The connectors were often clumsy and required lining up numerous pins to fit the holes in the female end connectors. They also comparatively provided slower transfer rates that the USB connector.
USB stands for Universal Serial Bus. USB connectors are used to link up different types of USB cables with a standard compatible USB port. The primary work of the USB cables if for data transfer. Data transfer speeds vary from 12 Mbps in version 1.1 and up to 480 Mbps in version 2.0. USB ports can also be used to connect several PC accessories by substituting their particular cables with the USB connectors.
How It Works
USB devices use low to medium bandwidths, and they can be plugged in and remove even with the system running. When the computer enters power saving mode, the USB device is automatically put to sleep mode. When the system powers up, it searches all the devices and assigns an address for the devices connected. The computer then finds out from each device the type of data transfer that it needs to perform. When removing the USB device, it is not necessary to switch off or reboot the system.
The USB allows you the chance of being able to connect with up to 127 devices on your computer. Most devices will have the USB connector at their back, but there are some computers which have it on their front. Once you plug in, the operating system automatically searches and detects the new device. If you are in possession of the driver disk, be sure to enter it when the system asks for it. If the device was previously installed, the system starts communicating with it immediately. The USB devices come with their in-built cables and have an “A” connection on it. If the in-built connector is not available, the device accepts the type “B” connector. Type “A” connectors head upstream while the “B” connectors head downstream and link devices. To avoid the confusion the standard USB Uses both “A” and “B” connectors.
As mentioned earlier, the USB has taken over a wide arrange of previously used interfaces like the serial and parallel ports as well as the individual power chargers for portable devices. USB connectors are now commonly used with devices like network adapters and portable media players as well as video game consoles and smartphones.
