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 the development of the USB, the main interfaces used were the parallel and serial connector that used different protocols to transfer data and control peripherals. These type of connectors were often clumsy and required lining up many pins to match the holes in the female connectors. They also comparatively provided slower transfer rates that the USB connector.
USB stands for Universal Serial Bus. The USB connectors are mainly used to connect different kinds of USB cables with all 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.
Universal Service Bus Operation Mechanism
USB devices need low to medium bandwidths, and it is possible to plug them in and remove when the system is still functioning. The moment the PC gets into the power saving modem the USB device automatically is put into the sleep 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 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. USB devices have their in-built cables and have a type “A” connection. If the in-built connector is not available, the device accepts the type “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.
