Back in the days where laptops and notebooks are packed in a big compartment, input and output ports were having no problem fitting into those devices. With time, technology grows more steeper in the charts. Laptop and notebooks transform into a more lightweight and slim designed devices. Ports tends to have a problem into fitting big sized ports to the devices. Because of that, manufacturers tried to develop their own “all-in-one” ports with a mission to eliminate unnecessary ports laying around. Apple Inc. were the first compony who started the movement of these “all-in-one” ports. Back then, Apple introduced the lighting cables on 12 September 2012. It shocked the world with its simplicity, usability, and portability. But the technology provided is enclosed for Apple devices only. The technology of simplicity forces the wave of evolution to turn back down.
Intel technology develop a port that has the same idea of the lighting cable that Apple has. ThunderboltTM is a new port that is developed by intel by using USB type-C connector. In conclusion, Thunderbolt was designed by Apple and Intel. With its latest generation Thunderbolt 3, it brings speed and versatility to USB-C. it was initially developed and marketed under the brand Light Peak and was sold around 2011. On 2009, at Intel Developer Forum was discussed how to transfer a video stream plus LAN and storage devices over a single cable with USB with its ends. This was inspired by the Mini DisplayPort that was also developed by Apple, that is why video transmission is the basics of the Thunderbolt port.
As expected in the rumors, the launch of the 2011 MacBook Pro product line will adapt several new data port types, and much of the speculation revolves around implementing Light Peak.  At that time there were no leaks that showed detailed system details similar to previous Intel demos that used a combination of USB and Light Peak. Unfortunately, shortly before the release of the new machine, the USB Implementer Forum (USB-IF) announced that Zafira would not allow this, they stated that the USB was not open for modification in this way.
Apart from comments and speculation, the introduction came as a big surprise when it was revealed that the Light Peak port was integrated into DisplayPort, not USB. As this system mechanism works, the solution provided by Intel in overcoming the display connection problem becomes clear: Thunderbolt folds data from an existing DisplayPort system with data from a PCI Express port into a single cable mechanism. The previous display connection, which uses DisplayPort 1.1, must be placed at the end of the Thunderbolt device chain, but a new display connection can be placed anywhere. Thunderbolt devices can go anywhere on the chain line.
At the end of February 2011, Apple introduced a new line of their portable computers, the MacBook Pro. It was also announced that the commercial name of this technology was Thunderbolt, where the machine was asked to be the first to adapt the new features of I / O technology. DisplayPort, a legacy from Apple, is fully compatible with Thunderbolt, and both share the Mini DisplayPort connector. The Thunderbolt port on the new MacBook Pro laptop is placed in the same location and is almost identical in appearance to the previous generation Mini DisplayPort.
At the end of June, Apple introduced this on their all in one computer, the iMac. In the 21 “model they provide 1 thunderbolt channel and on 27” they introduce 2 thunderbolt channels which allow to connect to 2 displays at once (Cinema Display) and with a new Apple monitor, Thunderbolt display, Thunderbolt can be displaced.
Devices with Thunderbolt 3 ports began shipping at the beginning of December 2015, including notebooks running Microsoft Windows (from Acer, Asus, Clevo, HP, Dell, Dell Alienware, Lenovo, MSI, Razer, and Sony), as well as motherboards (from Gigabyte Technology), and a 0.5 m Thunderbolt 3 passive USB-C cable (from Lintes Technology).
This follows previous practice, where higher-end devices such as the second-generation Mac Pro, iMac, Retina MacBook Pro, and Mac Mini use two-port controllers; while lower-end, lower-power devices such as the MacBook Air use the one-port version.
Support was added to Intel’s Skylake architecture chipsets, shipping during late 2015 into early 2016.
In October 2016, Apple announced the updated MacBook Pro which features two or four Thunderbolt 3 ports, depending on the model. In June 2017, Apple announced new iMac models that feature two Thunderbolt 3 ports, as well as the iMac Pro, which would feature four ports when released in December 2017.
On 8 January 2018, Intel announced a product refresh (codenamed Titan Ridge) which enhanced robustness and added support for DisplayPort 1.4. The new peripheral controller is now capable of acting as a USB sink (compatible with regular USB-C ports).
Intel offers a single port (JHL7340) and double port (JHL7540) version of this host controller and a peripheral controller supporting two Thunderbolt 3 ports (JHL7440).
Unlike Thunderbolt 1 and 2 cables which are available in longer lengths via optical cables, Thunderbolt 3 optical cables have yet to be released
For the first time, one computer port connects to Thunderbolt™ devices, to every display and billions of USB devices. Now, just one compact port can enable lightning-fast data transfer, support two 4K UHD 60 Hz displays2, and even provide quick laptop charging. Expand your capabilities while reducing cables with the simplicity of a single Thunderbolt™ 3 port paired with the latest 8th Generation Intel® Core™ processor. Incredible data transfer rates deliver exciting potential for multi-streaming HD and 4K UHD video to multiple monitors, or transfer 4K UHD movies and hours of 4K UHD GoPro* footage with ease. With an unprecedented speed of 40Gbps, Thunderbolt™ 3 technology provides the bandwidth to do it all.
