A type B USB uses a removable cable like a printer and is connected to an upstream port. The input device, keyboard and mouse are a well-known example of type A USB connectors. And, to supply power and transmit data, it is inserted into a USB or hub host. Type A is USB 2.0, which contains a flat rectangle interface. There are many types of USB connectors, but type A and type B are one of two major types. Then, Intel Compaq, Microsoft, and other companies adopted this industry-standard quickly. Its first version 1.0, was introduced in January 1996. In the devices like smartphones and tablets, a USB may also use for supplying power as well as charge their batteries. Without having to restart the computer, plug-and-play makes it capable of operating the system to involuntarily discover and configure, and hot-swapping allows replacement and removal of a new peripheral device.

With a single USB port, up to 127 peripherals can be connected with the help of a few USB hubs, although that will need quite a bit of dexterity.Ī USB is intended to allow hot-swapping and enhance plug-and-play. The USB has replaced a wide range of interfaces like the parallel and serial port because it is used for a wide variety of uses as well as offers better support for electrical power. It is the most common interface used in today's computers, which can be used to connect printers, scanners, keyboards, mice, game controllers, digital cameras, external hard drives and flash drives. A USB is a common computer port, which shorts for Universal Serial Bus and allows communication between a computer and peripheral or other devices.
