The Standard-B is used at the device side. Since USB 2.0 and USB 3.0 ports may coexist on the same machine and they look similar, the USB 3.0 specification recommends that the Standard-A USB 3.0 receptacle have a blue insert (Pantone 300C color). The same color-coding applies to the USB 3.0 Standard-A plug.
USB-C is the emerging standard for charging and transferring data. USB-C cables can carry significantly more power, so they can be used to charge larger devices like laptops. They also offer up to double the transfer speed of USB 3 at 10 Gbps.
I wouldn't think there's any performance decrease from USB-C compared to HDMI. USB-C display use Thunderbolt 3 and that's really powered by the DisplayPort. So, if I'm using my USB-C, I can't use DisplayPort concurrently. But I could use both USB-C and HDMI together.
Apple's Lightning port is proprietary and USB-C is universal. Every Android phone has a USB-C port. Hell, even Apple has exercised extreme courage by ditching Lightning on the iPad Pro with USB-C; the iPad Air 4 will do so, too. All of Apple's MacBooks only come with USB-C ports.
Short answer: USB type C cables are quite likely to replace HDMI cables, but HDMI will live on within the USB type C cables. So no, USB type C won't replace HDMI, it will just provide HDMI connectivity in a different physical form. USB type C is a physical connector, ie: plug, socket and cable.
USB 3.1 is backwards compatible with USB 3.0 and USB 2.0, except in the following scenarios: USB-B 3.1 cables are not compatible with USB-B 2.0 ports. Devices that require USB 3.1 transfer speeds of 10Gbps might not work with USB 3.0 or USB 2.0, or you might experience lower transfer speeds and impacted performance.
Q:USB 3.0 cable is compatible with USB 2.0 port? A: Yes, USB 3.0 is backwards compatible, though it will only work at USB 2.0 speeds.
With the right data standard (see below), USB-C is much faster and more versatile than USB-A. In time, you can expect USB-C connections to replace all older USB-A connections and other ports.
Universal Serial Bus Type-C
Type-C USB and USB 3.1 are backward-compatible with USB 3.0 and USB 2.0. In a pure Type-C USB connection, the Type-A ports and plugs are no longer included. However, you'll find compatible Type A-to-Type C cables. On top of that, there will be adapters to make Type C hosts and devices work with existing USB devices.
A USB-C connection can charge devices up to 20 times faster than basic USB. USB-C ports support USB Power Delivery, a fast-charging standard that can deliver 100 watts of power to compatible devices.
This means that smartphones, tablets, laptops, cameras, and any other devices with a USB-C port can be built to directly output video to any HDMI display with a single cable. USB-C devices that support these Alt Modes can then, with the correct USB-C cable, transfer those signals in addition to regular USB data.
Devices like wireless mice, keyboards, speakers, and smart home devices, all either currently do, or could in the future, offer USB-C ports, both for power delivery and data transfer. USB-C is rapidly appearing on storage devices from flash drives to external hard drives, thanks to USB-C's 10 Gbps transfer rate.
Today, there are three main connectors. Android devices typically use USB-C or the older micro-USB, and Apple uses Lightning.
USB Type-C is more flexible and faster than micro USB. According to a survey, Type-C port can be used to input or output power, while micro USB can only input power. USB Type-C port has a fast charging speed for phones at 18 Watts and can charge laptops with a maximum of 100 Watts.
It lets you connect a USB 3.1 Type C cable or devices to the rear of your PC without needing an adapter. Type C is good because it's slim, can transmit more power (like for charging devices), and the connector works if you insert it upside down.
USB Type-C goes in either way, upside down or right-side up, taking the guesswork out of the plug-and-play game. The USB Type-C connector can potentially provide up to 100 watts of power, so you can use it to power and charge cell phones, laptops, and tablets, as well.
You can generally tell the difference between USB 1.0, 2.0, and 3.0 by color alone. While the size and shape may be identical, the key is to look at the color of the plastic inside the device. The USB 1.0 features a white plastic color, while USB 2.0 is black, and the USB 3.0 is blue.
