Developed in the 1990s, the Universal Serial Bus (USB) standard was developed to define communication protocols, including cables and connectors, between computers and electronic devices such as printers and scanners. As the number of devices multiplied in quantity and types, the USB port was adopted as the basic connection portal.
Devices like smartphones, PDAs, tablets, smartphones and video game consoles can connect to computers with USB ports allowing recharging and communication thereby replacing the requirement of adapters and power chargers.
USB3.0 was released in November 2008, almost eight years after the release of USB 2.0. Over five years later, in 2014, USB 3.1 was released with widespread use expected in 2015.

The newest standard is for USBs is USB 3.1. It offers three major improvements over 3.0: an 'always right' C-type connector that plugs in without regard to orientation, higher data transfer speeds of up to 10 Gbps (gigabits per second), and the capacity to power any type of device.
Welcome to pySerial’s documentation¶. This module encapsulates the access for the serial port. It provides backends for Python running on Windows, OSX, Linux, BSD (possibly any POSIX compliant system) and IronPython. Serial interfaces use a PPP connection (point to point connection) but Fa is a fast ethernet port which can provide a speed of 100 mb/s and to this port can be connected a ethernet switch but to Serial port not. The digits 0/0/0 means the number of module/submodule/port number, when you are logged on a real equipment there could be a different numbering depending of type of router.
The C-type connector is small enough for modern, slim devices, such as MacBook Air-type notebooks, tablets, and smartphones. but still robust enough for 10,000 cycles of use. Data transfer speeds are more in sync with current app and user needs, especially for video and image files. And the option to connect to and power any type of device, with 100 watts of charging power that can be divided between two devices, greatly reduces 'charger and cable clutter,' simplifying connectivity between personal devices. However, backwards compatibility will be limited.
When data is being transferred through USB 3.0 devices, cables, and connectors, the transaction is initiated by the host making a request followed by a response from the device. The device either accepts the request or rejects it. If accepted, the device sends data or accepts data from the host. If there is lack of buffer space or data, it responds with a Not Ready (NRDY) signal to tell the host that it is not able to process the request. When the device is ready then, it will send an Endpoint Ready (ERDY) to the host which will then reschedule the transaction.
USB 3.0 Connectors are different from USB 2.0 Connectors and the 3.0 connectors are usually colored blue on the inside in order to distinguish them from the 2.0 connectors.
USB 3.0 is compatible with USB 2.0. However, the USB 3.0 product will perform at the same level as a USB 2.0 product, so speed and power benefits will not be fully realized.
USB 3.0 receptacles are electrically compatible with USB Standard 2.0 device plugs if they physically match. USB 3.0 type-A plugs and receptacles are completely backward compatible, and USB 3.0 type-B receptacles will accept USB 2.0 and earlier plugs. However, USB 3.0 type-B plugs will not fit into USB 2.0 and earlier receptacles.
This means that USB 3.0 cables cannot be used with USB 2.0 and USB 1.1 peripherals, although USB 2.0 cables can be used with USB 3.0 devices, if at USB 2.0 speeds.

Used for communication between the Arduino board and a computer or other devices. All Arduino boards have at least one serial port (also known as a UART or USART), and some have several.

On Uno, Nano, Mini, and Mega, pins 0 and 1 are used for communication with the computer. Connecting anything to these pins can interfere with that communication, including causing failed uploads to the board.
You can use the Arduino environment’s built-in serial monitor to communicate with an Arduino board. Click the serial monitor button in the toolbar and select the same baud rate used in the call to begin().
Serial communication on pins TX/RX uses TTL logic levels (5V or 3.3V depending on the board). Don’t connect these pins directly to an RS232 serial port; they operate at +/- 12V and can damage your Arduino board.
To use these extra serial ports to communicate with your personal computer, you will need an additional USB-to-serial adaptor, as they are not connected to the Mega’s USB-to-serial adaptor. To use them to communicate with an external TTL serial device, connect the TX pin to your device’s RX pin, the RX to your device’s TX pin, and the ground of your Mega to your device’s ground.
