How the USB Connectors Work

The USB has come a long way since it was developed in 1995 and was originally designed to simplify how consumers controlled peripherals and transferred data. Before then, he main interfaces that were used to transfer data and control peripherals were the parallel and serial connectors that used different protocols to perform this task. 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 connect different types of USB cables with all standard compatible USB ports. USB cables are primarily used to transfer data. The two version available of the USB is the 1.0 and 2.0 and both have varying speeds of 12Mbps and 480 Mbps respectively. USB ports can also be used to connect several PC accessories by substituting their particular cables with the USB connectors.

Universal Service Bus Operation Mechanism
USB devices use low to medium bandwidths, and they can be plugged in and remove even with the system running. Whenever the system enters the power saving mode, the USB device is automatically put into the sleeping mode. When the system powers up, it searches all the devices and assigns an address for the devices connected. Next, the computer will find out from each device the kind of data transfer it wishes to carry out. When removing the USB device, it is not necessary to switch off or reboot the system.

The universal service bus offers a simple standard way of connecting up to 127 devices to the computer. Most devices will have the USB connector at their back, but there are some computers which have it on their front. As soon as you plug in, the operating system will automatically search and detect the new device. Incase you have the driver disk, make sure that you insert it once the operating system asks you to do so. If you had installed the device prior, the system will start interacting with it on plugging. USB devices have their in-built cables and have a type “A” connection. In the absence of the inbuilt cable, the device accepts a USB “B” connector. The type “A” connectors head upstream while the “B” connectors head downstream and link to devices. The standard USB uses the “A” and “B” connectors to avoid any controversy.

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. Of late, USB connectors are being used with devices such as network adapters, video consoles, portable media players as well as smartphones.
