What is Thunderbolt?
▪ A display interface that is used for data transfer
68
Thunderbolt version 1 and 2
Thunderbolt version 1 and 2 used a physical connector that were backwards compatible
69
Thunderbolt 1 - history
Thunderbolt 1 is the first product in the series that was integrated into the MacBook Pro laptop in the year 2011. It achieves a data rate of 20Gbps in such a way that it bears four channels of 10 Gbps each for data transmission. It uses the architecture of the Mni-DisplayPort connector under the protocol 4 x PCIe 2.0 DisplayPort 1.1a.
70
Thunderbolt 2 - History
Difference between Thunderbolt 1 and 2 Although Thunderbolt 2 is physically identical to its previous version, it stands out with the feature of channel bonding to simultaneously display as well as transfer a complete 4K video. While Thunderbolt 1 has 4 channels, Thunderbolt 2 combines two channels so overall it has two channels, each of 20Gbps. Thus with the same bandwidth as Thunderbolt 1, Thunderbolt 2 causes less overhead and enables more efficient transfers.
71
Thunderbolt 3 - history
Thunderbolt 3 shares close similarities with the USB Type C connector. It supports a connection speed of 40Gbps per second. It is capable to supply two 4K displays simultaneously and transfer the audio as well as video files at the same time. Quick Notebook charging is another attractive feature. It was launched in the market in late 2015. Later, USB 4 was released in August 2019 based on the specification of Thunderbolt 3. All Thunderbolt version 3 will support USB-C, but not all USB-C we'll support Thunderbolt 3 Max cable length for max speed is 1.6ft
72
What is the data transfer over cables for Thunderbolt?
Supports speeds of up to 40 gigabits per second for data transfer over cables
73
What is Lightning Cable?
A specific proprietary connector that was created by Apple their mobile devices
74
What is SATA Cable?
Serial Advanced Technology Attachment ▪ The standard cables that are the main method of connecting a storage (e.g. HardDrive to Motherboard) device to a motherboard inside of a desktop computer ▪ The SATA cable has two cables, one is a seven-pin data cable, which does not supply any power, and the other is a 15-pin SATA power connector to provide the power to the device
75
SATA version 1 can support speeds of up to?
SATA version 1 can support speeds of up to 1.5 gigabits per second
76

78
What is External SATA ?
A SATA cable on the outside of the case
79
What is PATA cable?
The old IDE connectors with the exact same cables and connectors and standards but renamed for branding
80
Parallel devices have each cable support up to how many devices?
Parallel devices have each cable support up to two devices and they both can communicate at the same time
80
What is a Molex Power Connector?
A 4-pin connector that would attach from the power supply directly to a device
81
What is a SCIS connector?
