6 Facts About Products Everyone Thinks Are True

A Guide to USB Connectors

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. 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 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 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 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. When the system powers up, it enquires 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 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. 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. 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. 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. USB connectors are now commonly used with devices like network adapters and portable media players as well as video game consoles and smartphones.
