How the USB Connectors Work
USB has come quite a long way since its conception in the year 1995, and it was initially designed to simplify how the users 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 type of connectors were often clumsy and required lining up many pins to match the holes in the female 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. The primary work of the USB cables if 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. 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. When removing the USB, you do not need to reboot or switch off 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. 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. The type “A” connectors head upstream while the “B” connectors head downstream and link to devices. To avoid the confusion the standard USB Uses both “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.
