Bandwidth refers to the maximum volume of data a network can transmit per second, acting as a strict upper limit on its transfer speed.For example, if the bandwidth of a network is 50 Mbps, it implies that the network cannot transmit data faster than 50 Mbps in any given case.
Bus-powered means a device draws its electrical power directly from the data cable connected to the host computer, eliminating the need for an external power supply.

Fast Charging is a technology that increases charging wattage (by raising voltage or current) to deliver more power to a device's battery, significantly reducing the overall charging time.
GaN (Gallium Nitride) is a next-generation semiconductor material used in modern chargers to deliver higher power output and faster charging speeds in a significantly smaller, cooler-running size compared to traditional silicon.
Graphical Anomalies (also known as artifacts or glitches) refer to unintended visual distortions or errors displayed on a screen, usually caused by hardware overheating, driver issues, or software bugs.
A gyroscope is a sensor or device that measures or maintains rotational motion and orientation, allowing technology to detect exactly how it is being tilted, turned, or rotated in 3D space.
Heat Dissipation is the process of transferring and removing excess heat away from a device or component to the surrounding environment to prevent overheating and maintain optimal performance.
MagSafe products use Apple's official certified technology to deliver maximum 15W/25W wireless charging and exclusive animations, while MagSafe Compatible products use third-party magnets to mimic the magnetic alignment but are limited to slower 7.5W charging speeds.
Memory (RAM) is the volatile, ultra-fast temporary workspace where your device processes active tasks, while Storage (SSD/HDD) is the non-volatile, large-capacity permanent warehouse where all your files and applications are saved.
NFC (Near Field Communication) is a short-range wireless connectivity technology that allows devices to securely exchange data or make contactless payments when brought within a few centimeters of each other.
NVMe is a high-performance storage protocol designed specifically for SSDs that utilizes the fast PCIe bus to deliver significantly faster data transfer speeds and lower latency compared to legacy SATA protocols.
PCIe Tunneling is a technology used in USB4 and Thunderbolt that encapsulates native PCIe data packets within a single high-speed connection, allowing external devices like eGPUs and NVMe SSDs to communicate directly with the CPU over a Type-C cable.
Qi is the global universal standard for wireless charging, and its latest version, Qi2, integrates magnetic alignment (similar to Apple's MagSafe) to ensure perfect placement and faster 15W charging across both Android and iOS devices.
Qi2 is the next-generation universal wireless charging standard that incorporates Apple's magnetic alignment technology to deliver precise, cooler-running 15W fast wireless charging for both Android and iOS devices.
Resolution refers to the number of pixels on a screen determining image sharpness and clarity, while Refresh Rate is the number of times the screen updates per second (measured in Hz) dictating the smoothness of motion and animations.
SATA is a legacy data transfer interface and protocol used to connect storage devices (like HDDs and older SSDs) to a computer's motherboard, with a maximum real-world speed limit of around 550MB/s.
Thunderbolt is a high-speed hardware interface developed by Intel and Apple that utilizes the Type-C connector to deliver massive bandwidth (up to 40Gbps/80Gbps) for simultaneous fast data transfer, dual 4K/8K video output, and high-wattage power delivery.
Transfer Rate refers to the actual speed at which data is successfully moved from one location or device to another over a given period, typically measured in MB/s for storage devices or Gbps for connectivity interfaces.
UHS-I and UHS-II are SD card bus standards, where UHS-II features a second row of physical pins on the back to deliver up to three times faster data speeds (up to 312 MB/s) compared to UHS-I for demanding tasks like high-speed burst photography and 4K/8K video recording.
An Upstream or Host Port is the primary port on a docking station or monitor explicitly designated to connect back to the main computer (the host), allowing all other connected peripherals to communicate with it.
USB 3.2 Gen $1 \times 1$ is the confusing, re-branded technical name for the classic USB 3.0, delivering a maximum data transfer speed of 5Gbps over either a Type-A (typically blue) or Type-C connector.
USB 3.2 Gen $2 \times 1$ is the official technical name for USB 3.1 Gen 2, delivering a maximum data transfer speed of 10Gbps (around 1000 MB/s in the real world) over either a Type-A or Type-C connector.
USB 3.2 Gen $2 \times 2$ (SS+) utilizes two parallel lanes over a Type-C connector to double the bandwidth of Gen 2, reaching a blazing-fast maximum data transfer speed of 20Gbps (around 2000 MB/s).
USB-C (Type-C) is a universal, reversible 24-pin physical connector standard that can simultaneously handle high-speed data, ultra-high-definition video output, and up to 240W of power delivery depending on its underlying protocol.
USB-C PD (Power Delivery) is a universal fast-charging standard delivering up to 100W/240W of power via a Type-C connector, using smart chip communication to dynamically negotiate the safest and fastest voltage for any compatible device.
USB4 is a next-generation standard built on the Thunderbolt 3 architecture that utilizes the Type-C connector to deliver massive bandwidth (up to 40Gbps/80Gbps), intelligent dynamic bandwidth allocation, and PCIe tunneling support.
Volts measures electrical pressure, Amps measures the rate of current flow, and Watts is the total power output calculated by multiplying Volts by Amps ($W = V \times A$), which directly determines charging speed.
