Specifically refers to the capacity at which a network can transmit data. For example, if the bandwidth of a network is 40 Mbps, it implies that the network cannot transmit data faster than 40 Mbps in any given case.
The hub and/or adapter relies on the power provided by the port of the host device in order to function.
Provides a universal docking solution to any platform, enabling multiple displays, audio, Ethernet, and other USB peripherals to be connected to PCs, Macs, and tablets through the USB port (including USB-C port) or the wireless connection.
An E-Marker (electronic marker) is a chip that is used in the latest USB connector iteration, USB Type-C, to communicate between power source and power sink devices. The chip is used to communicate with connected devices to ensure safe data and power delivery to and from the source and sink.
Chargers with an output of 15W or more are considered fast-charging. Depending on the host device, the minimum requirement varies among different devices and platforms.
Gallium Nitride - a very hard, mechanically stable wide bandgap semiconductor. With higher breakdown strength, faster switching speed, higher thermal conductivity, and lower on-resistance, power devices based on GaN significantly outperform silicon-based devices.
Glitches or color correction issues in regards to video output with our cables, hubs and adapters.
A device that is used to measure and maintain the orientation and angular velocity of an object. In regards to the R2 remote, with the AirMouse feature, the gyroscope sensor can detect the movement and direction of the remote to control the cursor of the host device. This would work for controlling the mouse from a long distance or using the cursor in a presentation to point out an object.
Thermal dissipation refers to a form of heat transfer. Heat transfer in this respect occurs from an object that is hotter, to surrounding objects and environment that are cooler. In many industries particularly those involving technology, this can be deleterious as it “corrosion under insulation”.
MagSafe Compatible vs, MagSafe
A magnetic technology from Apple, built into the internal engineering of iPhone 14/13/12 models. Originally created as a safety feature for MacBook charging cords, MagSafe was incorporated into the iPhone 14/13/12 to create a new ecosystem of accessories for easy attachment and faster wireless charging.
Memory vs Storage
Memory is what your computer uses to store data temporarily, while storage is where you save files permanently.
NFC (near field communication) is the technology that allows two devices — like your phone and a payments terminal — to talk to each other when they're close together. NFC is the technology that enables contactless payments.
NVMe (nonvolatile memory express) is a storage access and transport protocol for flash and solid-state drives (SSDs) that delivers the highest throughput.
USB4 introduces the idea of tunneling, which allows multiple protocols to be combined over a single interface to increase flexibility. USB 3.2 data, display (DisplayPort), and load/store (PCIe) information tunneling is possible depending on the device.
Qi is a wireless charging standard used for wirelessly powering electronic devices such as smartphones, headsets, and wearable gadgets. Besides this, it also talks about the security and interoperability between Qi-enabled devices. Now you may be wondering what is a Qi device. A Qi device is certified hardware designed to charge batteries according to the norms of the Qi standard. Any device following this standard for wireless charging can be called a Qi device and use the same wireless chargers.
Based on the same idea as Apple's MagSafe, but it's a universal standard designed for all smartphones moving forward.
Resolution vs Refresh Rate
Resolution is the clarity of the display's image; higher resolution results in more vivid images. Refresh rate is the responsiveness of the video and movement of images; the higher the refresh rate, the smoother the playback.
SATA (also referred to as Serial ATA) stands for Serial Advanced Technology Attachment, an industry-standard bus interface for connecting a computer's host bus adapter to storage devices such as hard disk drives (HDD), optical drives, and solid-state drives (SSD).
Thunderbolt ports are completely compatible with USB-C devices and cables, but they have a few extra features that make them stand out from USB-C ports. For example, you can connect multiple external 4K monitors and Thunderbolt extension docks to your PC.
A Thunderbolt expansion dock lets you connect a single cable to a Thunderbolt port and then provides different kinds of ports to your PC. These may include an Ethernet connector, an HDMI port, multiple USB ports, and a 3.5 mm headphone jack. Conversely, USB C can only offer individual connections in single ports.
Transfer Rate (Transfer Speeds)
Transfer rate is the speed at which data moves between two locations. As a baseline, transfer rates were stated in bits per second (bps) or bytes per second (Bps). However, with modern Internet, transfer rates are commonly measured in megabits per second (Mbps) and gigabits per second (Gbps) as speeds are increased.
UHS-I vs UHS-II
UHS-I bus interface, with transfer rates up to 104 Mb/s, debuted as the first upgrade from normal, high-speed specification.
Next, came UHS-II, which bumped up the speeds to 312 Mb/s. Perhaps the most prominent difference from its first version, was the added 2nd row pins, which uses Low Voltage Differential Signaling (LVDS) technology to allow higher transfer rates.
UpStream / Host port
The port that requires a connection to the computer or other host device.
USB 3.2 Gen 1X1 (USB 3.0)
5 Gbps transfer speeds. Can be in either USB-A or USB-C formats.
USB 3.2 Gen 2 X 1 (USB 3.1)
10 Gbps transfer speeds. Can be in either USB-A or USB-C formats.
USB Gen 1 X 2/ 2 X 2(SS+)
20 Gbps transfer speeds. Typically in USB-C formats.
Type-C refers to the physical shape of the newest USB connector.
USB-Power Delivery (PD) is a fast-charging technology based on the USB-C standard. Certain Apple® and Android smartphones/tablets and various laptop brands support the technology, which provides much higher performance than standard charging methods.
USB-C PD is a new standard that can deliver up to 240 watts of power, which is enough to charge laptops and other devices that require more power than USB-C alone can supply. This specification was created by the USB-IF in response to requests from laptop manufacturers for a connector that could deliver more power.
The USB-C PD standard is compatible with the USB4 and USB Power Delivery 3.1 specifications. The USB-C PD specification defines how devices can use the USB-C connector to supply power and how these devices are identified and managed. It defines what the pins in the connector do and how they can be used to provide power at various voltages and currents.
USB4, sometimes referred to as USB 4.0, is a technical specification that the USB Implementers Forum released on 29 August 2019. USB4 is based on the Thunderbolt 3 protocol specification, which Intel has donated to the USB-IF, but is aligned with the Thunderbolt 4 specification.
Volts/ Amps / Watts
Amps measure the electrical current or the speed at which electrons flow through a conductor. Volts measure the electrical voltage and represent the difference in electrical potential. Watts is the rate at which electrical energy is transferred in a circuit. Watts are a measure of power. When amps and volts combine, they result in watts (amps x volts = watts). Watts is a measurement of the amount (or more specifically the rate) of energy or power released or used.
