You sould KNOW!!! What is USB or Univesal Serial Bus?
Everyone has used at least once a device that was connected to another device with the help of a USB port. Whether we are talking about flash
memory sticks or other peripherals like printers, many device are using the USB standard connector. In this article we will share what USB stands for,
What it does what are the advantages and disadvantages of using USB to connect device.
What Does USB Mean?
USB stands for Universal Serial Bus and it is a term that defines cables, connectors and communications protocols used in communication between devices.
It was designed in 1996 by a group of seven companies that included Microsoft, Compag, IBM, Intel, DEC, NEC and Nortel. It
purpose was to standardize the connection between peripheral devices like printers, Keyboards, mice and personal computers.

purpose was to standardize the connection between peripheral devices like printers, Keyboards, mice and personal computers.
These companies wanted to replace the multitude of connectors that were used back then,
removing problems like the usability issues of existing interfacs and simplifying the software configuration of all devices
that were connected via USB, as well as permitting greater data transfer rates between devices.
USB has become a very successful standard and it is now used by many devices in the world.
Today there is no computer that's manufactured without at least on USB port.
Types of USB Connectors
the are two USB standard plugs: Standard A and Standard B. they are show in the diagram below.
If you haven't realized yet, the USB connector is an electronic device, so like any other electronic device it needs electrical energy to operate.
It receives energy through pins 1 and 4, and the data is transferred through pins 2 and 3.
Nowadays, almost any device you can buy can be connected to a personal computer via the USB interface, whether it is a keyboard, mouse, smartphone,
Pinter or something else, Even a device that's designed and built by you can be connected with your computer. Also, the USB
interface permits power supply exchanges between computers and electronic devices.
For example, this means that the battery of a smartphone will charge while the device is connected to a computer via USB.
In order to use this new technology on smaller devices like cell phones, portable game consoles or other similar devices, the Mini USB port was released in October 2000.
This connector is rated at 5.000 connect-disconnect cycles. it has been used by PDA's and early smartphones.

In 2007, the new Micro USB was announced. The thinner micro connectors are intended to replace Mini USB in new device including Smartphones, Personal digital assistants,
and cameras. The Micro USB plug design is rated for at least 10.000 connect-disconnect cycles, which is more than the Mini USB plug design.
This plug has revolutionized the way portable devices are connected. The Micro USB was endorsed as the standard connector for data and power on mobile device and as a universal
charging solution, You can see it in the diagram below.

In order to use the speed rates of USB 3.0 on smartphones, the Micro USB 3.0 connector was created. It consists of a standard USB 2.0 Micro USB cable plug with 5 additional pins.
The Micro 3.0 receptacle is compatible with the Micro USB 2.0 plug. Samsung Galaxy Note 3was the first smartphone to include this connector. and so on !!!
