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 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. Data transfer speeds vary from 12 Mbps 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.
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. When the computer enters power saving mode, the USB device is automatically put to sleep mode. When the system powers up, it searches 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. 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. 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. The USB devices come with their in-built cables and have an “A” connection on it. If the in-built connector is not available, the device accepts the type “B” connector. Type “A” connectors head upstream while the “B” connectors head downstream and link 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.
