USB Connectors-Tips and How they 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. Also, they had slower transfer rates compared to the USB connector.
USB is an abbreviation for Universal Serial Bus. The USB connectors are mainly used to connect different kinds of USB cables with all standard compatible USB port. USB cables are primarily used to transfer data. The data transfer speeds may vary from 12Mbps 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.
The Working Mechanism of the USB
USB devices require low and medium bandwidths and can be plugged in and our anytime even when the system is running. When the computer enters power saving mode, the USB device is automatically put to sleep mode. When the system powers up, it enquires 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. You don’t have to switch off or restart the system to remove the USB device.
The USB allows you the chance of being able to connect with up to 127 devices on your computer. The USB connector is generally found at the back of your machine, but in some machines it can be found at the front as well. Soon after plugging in, the operating system will automatically search and discover 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 the device had been previously connected, the system would start the communication process soon after plugging it in. The USB devices come with their in-built cables and have an “A” connection on it. In the absence of the inbuilt cable, the device accepts a USB “B” connector. The “A” connector leads upstream while the type “B” connector head downstream and link to devices. To avoid confusions, the standard USB uses “A” and “B” connectors.
As mentioned earlier, the USB interface replaced a wide range of previous interfaces such as the serial and parallel ports and 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.
