USB Connectors-Tips and How they Work
The USB has come a long way since its establishment in 1995 with its main purpose being to ease the way consumers 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. These connectors were often cumbersome and required lining up several pins to fit the holes in the female end connectors. They also offered slower data transfer rates as compared to the USB connector.
USB is an abbreviation that stands for Universal Serial Bus. The USB connectors are mainly used to connect different kinds of USB cables with all standard compatible USB port. Primarily, USB cables are used for data transfer. The data transfer speeds may vary from 12Mbps in version 1.1 and up to 480 Mbps in version 2.0. USB ports also can be used to connect numerous computer accessories by replacing their specific cables with USB connectors.
The Working Mechanism of the USB
USB devices need low to medium bandwidths, and it is possible to plug them in and remove when the system is still functioning. Whenever the system enters the power saving mode, the USB device is automatically put into the sleeping mode. Once the system has been powered on, it enquires all the devices and allocates an address for the devices connected. Then, the computer will find out from each of the devices the type of data transfer it has 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. 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. 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 come with their inbuilt cable and have an “A” connection on it. In the absence of the inbuilt cable, the device accepts a USB “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.
The USB has replaced many interfaces that have been used in the past like the parallel and the serial 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.
