Well, they are the type of USB ports used in smartphones, Bluetooth, speakers,etc. If you did notice, you would have found a difference in your smartphone's charging port and the charging port of latest flagships(unless you own one of the latest flagships), Yeah they have got a new type of port which is acknowledged as Type C. The common port used is micro B on previous of non-flagship smartphones.

(1) USB TYPE-C
USB-C, technically known as USB Type-C, is a 24-pin USB connector system, which is distinguished by its rotationally-symmetrical connector.The USB-C connectors connect to both hosts and devices, replacing various USB-B and USB-Aconnectors and cables with a standard meant to be future-proof.The 24-pin double-sided connector is slightly larger than the micro-B connector.
Audio Adapter Accessory Mode
USB-C plug supports analog headsets through an audio adapter accessory with a 3.5 mm socket providing four standard analog audio signals (Left, Right, Mic, and GND). The audio adapter may optionally include a USB-C pass-through plug to allow 500 mA device charging. The engineering specification states that a 3.5 mm analog headset jack should not replace a USB-C plug.
Analog signals use the USB 2.0 positive differential pair (Dp) and the two side-band use pairs. The presence of the audio accessory is signalled through the configuration channel and VCONN.
Alternate Mode
An Alternate Mode dedicates some of the physical wires in a USB-C 3.1 cable for direct device-to-host transmission of alternate data protocols. The four high-speed lanes, two side-band pins, and (for dock, detachable device and permanent cable applications only) two non-SuperSpeed data pins and one configuration pin can be used for alternate mode transmission. The modes are configured using vendor-defined messages (VDM) through the configuration channel.
Compatibility with other fast charging technology
In 2016, Benson Leung, an engineer at Google, pointed out that Quick Charge 2.0 and 3.0 technologies developed by Qualcomm are not compatible with the USB-C standard. Qualcomm responded that it is possible to make fast charge solutions fit the voltage demands of USB-C and that there are no reports of problems; however, it did not address the standard compliance issue at that time. Later in the year, Qualcomm released Quick Charge 4 technology, which cited – as an advancement over previous generations – "USB Type-C and USB PD compliant".
ADVANTAGES OF USB TYPE-C
It’s small. The new port is half the width and one-third the height of a standard USB connector and only slightly larger than Apple’s Lightning or the micro-USB connectors.
It’s reversible. Unlike older USB cable, it doesn’t matter which side is up with a Type-C plug; you can insert it either way.
It’s fast. Type-C ports can transfer data using the zippy speeds of the latest version of the USB protocol — up to 10 gigabits per second.
It’s powerful. The new connector can provide up to 100 watts of power, enough to power a laptop.
It’s flexible. Via adapters, users will be able to connect older devices to Type-C ports, even devices that use non-USB technologies, like DisplayPort, VGA and Ethernet

ADVANTAGE OVER MICRO USB-B
At first blush , type C looks slightly bigger than micro USB. Owing to its oblong reversible shape, you can plug it in whichever way without worrying about which side is up. This standard takes advantage of USB 3.1 and 3.0 data transfer speeds and a higher throughput capability to ensure a fast charge along with transfer rates from 5Gbps to 10Gbps. It can deliver up to 100W of power, enough to charge a laptop and other such devices. (Apple already uses this standard on their Macbooks).That said, you will probably come across USB 2.0 type C cables more often than not, especially for smartphone devices which don’t much require the extra oomph!.
Hope you guys have a clear view on TYPE-C and TYPE-B USB.
