Close the main features of USB type-C you should know drag
Updated on August 19:. Added the latest information about USB-C and Thunderbolt 3
Look around your house and chances are you at least a few devices that use Universal Serial Bus (USB). On average, approximately 3 billion USB ports are delivered each year, by far the most successful peripheral connection type to make.
In fact, the device manufacturers are so confident in USB-C, the Intel last year announced that Thunderbolt 3 (once thought to be a USB replacement) would use the same port type as USB-C. That means every Thunderbolt 3 port can also function as a USB C port and any Thunderbolt 3 cable as a USB-C cable.
Before you can fully appreciate what a leap forward both USB Type C and Thunderbolt 3 are, let’s make them with USB type-A, USB type-B and the different versions of the Thunderbolt standard.
Before 3 to Thunderbolt, Thunderbolt 2 and the original Thunderbolt shared the same cable type and port (which is the same port type as that of Apple Mini DisplayPort) and top data transfer speeds of 20 Gbps and 10 Gbps. With these older thunderbolt standards, the cable was active, which means the cable itself would need a device that requires power to operate any Thunderbolt 1 or 2 device would require external power to operate. This made thunderbolt a much more expensive solution, as the cable itself is about 10 times more expensive than a USB cable of the same length.
Here’s how Thunderbolt 3 differs from its predecessors:
The connection mini display type has been ditched in favor of a USB-C connection
All cable Thunderbolt 3 will work as a USB C cable.
All USB C cables will work as long as Thunderbolt 3 cables, as they are good quality cables.
Thunderbolt 3 has a top data transfer speed of 40Gbps as long as the cable. 5m (1.6 ft) or shorter.
For 1m (3.2 ft) or longer cable, Thunderbolt 3 passively supports (cheaper) those who have a top speed of 20 Gbps and active cables (more expensive) that retain the 40Gbps speed.
Thunderbolt 3 is backward compatible with earlier versions of Thunderbolt, but due to the new port type, adapters are required to use legacy Thunderbolt devices.
All USB C device (like a Nexus 6P phone) connected to a Thunderbolt 3 port will work normally.
Since Thunderbolt 3 devices will operate discrete Thunderbolt chips, they will not work if they are plugged into a USB C port.
All versions of Thunderbolt allow Daisy to six device concatenation together and in addition to the data can also wear Hi-def video and audio signals.
In the USB world, things have been a little more complicated because it has been called Thunderbolt more versions and types. In general, the models refer to the speed and functionality of the USB cable, while the USB type refers to the physical form and wiring of the connectors and connectors. Let’s start with the USB type.
For mostly type-a-ends (left of the coin) the USB cable stays the same over existing USB versions. Dong NGO/CNET USB Type-A
Also known as USB standard A, USB type-A is the original design for the USB standard and uses a flat rectangular shape.
On a typical USB cable the type a connector, also known as the A-plug, is the end that goes into a host, like a computer. And on a host, the USB port (or container) where the type a plug goes in, is called an A jack. Type a ports are mostly in host devices, including desktop computers, laptops, game consoles, media players and so on. There are very few peripheral devices that use a type a port.
Various USB versions including USB 1.1, USB 2.0, USB 3.0 (more versions below) currently have the same USB type a design. This means that a type-a port is always compatible with a type-a-event port if the device and host use other USB versions. For example, a USB 3.0 external hard drive also works with a USB 2.0 port and vice versa.

Similarly small devices such as mouse, keyboard or network adapters that always have hardwired USB cables use Type a connectors. This also applies to devices without cables, such as a USB stick.
USB 3.0 The ports and ports have more pins than USB 2.0. This is to deliver faster speed and higher performance. However, these pens are organized in such that they do not prevent physically working with the older version.
Also note that there are small type-a connectors and connectors, including mini-type-A and micro type-A, but there are very few devices that use these designs.
Popular USB Type-B: from links standard-B, mini-B, micro-B micro-B USB 3.0, and standard-B USB 3.0. Dong NGO/CNET USB-type-B
Typically the Type B connector is the other end of a standard USB cable that is plugged into the peripheral device (such as a printer, a phone, or an external hard drive). It is also known as type B-male. The peripheral device is called the B-female USB port.
Because the peripheral devices vary a great deal in shape and size, the type B connectors and its respective port also come in many different designs. So far there have been five popular designs for the USB Type B Plug and connectors. And since the type a end of the USB cable remains the same, the type B end is used to determine the name of the cable itself. (Wikipedia has a large USB plug matching matrix you can consult.)
The original standard (Standard B): This design was first used for USB 1.1 and is also in USB 2.0. It is mainly for large connection of peripheral devices such as printers or scanners to a computer
Mini-USB (or mini-B USB):. Significantly smaller, mini-USB, type B ports are found in older portable devices, such as digital cameras, smartphones and older portable drives. This design is now almost obsolete
Micro-USB (or micro-B USB):. Slightly smaller than mini-USB, the micro-USB Type B connector is currently being replaced by USB-C as the charging and data port for the latest smartphones and tablets
Micro-USB 3.0 (or micro-B USB 3.0). This is the largest design and especially used for USB 3.0 portable drives. Most of the time, the type a end of the cable is blue
Standard B USB 3.0. This design is very similar to the standard B, but it is designed to handle USB 3.0 speed. Most of the time, both ends of the cable are blue.
Note that there is also another, less popular, USB 3.0 powered-B Plug and socket. This design has two additional pins to supply additional power to the peripheral device. Also, there is a relatively rare micro type-AB port that allows the device to work on either a host or a peripheral device.

Not all devices use the standard USB cable mentioned above. Instead, use some of them to create your own design at the point of type B Plug and socket. The best known examples of these devices are the iphone and the ipad, where either a 30-pin or flash port takes place of type-B end. The type a end is still the default size.
USB 1.1: Released in August 1998 this is the first USB version to be widely adopted (the original version 1.0 never in consumer products). It has a maximum speed of 12 Mbps (although in many cases it only performs at 1.2 Mbps). It is largely outdated
USB 2.0. Released in April 2000, it has a maximum speed of 480 Mbps in hi-speed mode or 12 Mbps in full-speed mode. It currently has the maximum power put of 5 V, 1.8 A and is backward compatible with USB 1.1
USB 3.0 released in November 2008, USB 3.0 has the maximum speed of 5 Gbps in Super speed mode. A USB 3.0 port (and plug) is usually colored blue. USB 3.0 is backward compatible with USB 2.0 and its port can deliver up to 5v, 1, 8a power. This is ever sometimes called USB 3.1 Gen 1
USB 3.1 (sometimes referred to as USB 3.1 Gen 2.). Published in 26. July 2013, USB 3.1 doubles the speed of USB 3.0 to 10Gbps (now called Super + or Super Speed USB 10 Gbps) to make it as fast as the original Thunderbolt standard. USB 3.1 is backwards compatible with USB 3.0 and USB 2.0. USB 3.1 has three power profiles (according to the USB specification power delivery) and allows for greater device performance to be pulled from a host: up to 2 A at 5 V (with a power consumption of up to 10 W) and, if necessary, up to 5a for either 12v (60w) or 20v (100w). The first USB 3.1 products are expected to be available at the end of 2016 and will mostly use USB Type C design.

Physically the Type C connector and connector is about the same size as that of the micro-B USB mentioned above. A type C port measures only 8.4 mm from 2.6 mm. This means that it is small enough to work for the smallest peripheral devices as well. With type-C, both a USB cable ends are the same, so for reversible connector orientation. You also don’t need to worry about plugging in the head as it will work in both directions.
Since 2015, USB-C has been widely adapted and used in many smartphones and tablets. Many new storage devices also use USB C port instead of a USB B port. Almost all devices that use USB 3.1 port USB-C. USB 3.1 has the maximum speed of 10 Gbps and can deliver the power of up to 20v (100w) and 5a. If you are looking at most 15-inch notebook computers only require around 60 w of power, this means in the future laptop computers can be the way tablets and smartphones are now loaded, via their small USB port. In fact, Apple has been making its new MacBook, which has only one USB C port as the only peripheral and power connector.
Type-C USB also allows a bidirectional current, so that apart from the peripheral charger, if applicable, a peripheral device could also load a host device. All this means that you can do away with a number of proprietary power adapters and USB cables, and move to a single rugged and small solution that works for all devices. Type-C-USB is significantly currently cut a lot of wires required to make devices work
This is the first time adapters with USB are required, and probably the only time, at least for the foreseeable future. USB Implementers Forum, the group responsible for the development of USB says that type-C-USB is designed to be future-proof, the design sense for future and faster USB versions will be used.
It will take as popular as the current type-A on the host side a few years more for type-C, but if it does, it will simplify the way we work with devices. In fact, Intel is also working on a USB audio standard that could make the 3.5 mm audio jack superfluous. And with the addition of Thunderbolt 3 now being the super set of USB-C to be, finally, we just have one kind of connection and cable all the peripherals together and connect to one computer. It is predicted that thanks to support for USB-C, the adoption of Thunderbolt 3 will stand out, which was the case with earlier versions of Thunderbolt.
