The USB Adapter is a device that is used to connect other practical electronic devices to the computer. The connection is wired and the adapter, also called a USB cable, as two ends. There are various sizes and types to these ends; so for example, to connect a smartphone the adapter has a regular USB-A type end to be plugged into the USB port of the computer and a mini A or B USB end to plug into the phone.
The USB Adapter becomes necessary because of its universal application. “It uses the Universal Serial Port (USB) technology which was designed to standardize the connections between computers and their peripheral devices,” said Mark, a Product Manager from Topbuy.com.au. The USB Adapter is a wired electronic cord that links the computer to many USB capable computer peripheral devices. By doing so the USB Adapter eliminates the need generally for three other devices; the serial port that was mainly used to connect keyboard and mouse, the parallel port which was mainly used to connect printers, and a power charger for some devices like the cell phone since the printer still have its own power supply. USB adapter then is that middle cord or cable use for (1) connecting a device to a computer/laptop/tablet, (2) provides a communication channel through which the device and the computer communicates and (3) serve as a power supply for small devices like the cell phone and digital camera.
This triple function of the USB Adapter makes it very useful. Additionally, it is simple to install – just plug and play. Many modern USB devices are ready to use the technology that way. There are some devices, especially those made years ago that requires an installation CD or to download the software from the internet before the computer can recognize the device.
These USB adapters are so convenient and popular that many smartphones and digital cameras power cords are made with a dual function. These power cords can now have a portion of it detached and the USB adapter section plug into the computer and ready to you. The USB adapter charges the cell phone battery whether or not the device is in use.
The quality and speed of these adapters also makes them the connecting device of choice for many. Attaching a microphone to a computer using a USB adapter, for example, provides a better quality sound than using the regular microphone slot. This is so because the USB adapter prevents the element of noise.
There are also extensions to these USB adapters. These extensions may have one section to plug into the computer and several sockets to plug in additional USB devices.
