USB-C has better data rates than traditional USB ports, making it ideal for driving high-resolution monitors.
USB-C ports can support speeds of up to 10Gbps, with some newer ports supporting speeds of up to 20Gbps.
The USB-IF has announced that future USB-C ports will support speeds of up to 120Gbps with the USB4 specification.
Switches
Switches are a fundamental aspect of any electronic device, and understanding how they work is crucial for troubleshooting and repair.
A basic switch is essentially a mechanical or electrical component that can be flipped or pressed to make or break a connection, allowing or blocking the flow of electricity.
In the context of electronic devices, switches are often used to control power, activate features, or adjust settings. For example, the article mentions that the "Power Button" switch is used to turn the device on and off.
Some switches are designed to be highly reliable and durable, while others may be more prone to wear and tear. The article notes that the "Toggle Switch" is a type of switch that is commonly used in applications where a high number of on/off cycles are expected.
Switches can be found in various forms, including momentary switches, maintained switches, and toggle switches.
Compatibility and Adapters
USB-C ports are not all created equal, so it's essential to check the specs on any device you're considering buying. Not all USB-C ports support connecting DisplayPort and/or HDMI displays with an adapter.

The USB-C standard supports connecting DisplayPort and/or HDMI displays with an adapter, but not every device maker has connected the ports to the system's graphics hardware. This means some USB-C ports may support video-out connectivity, while others may not.
You'll need an adapter or cable with an appropriate plug to connect anything that doesn't have the USB-C oval shape. Apple sells a variety of USB cables and adapters for connecting USB-C to other technologies like Lightning or Ethernet.
A couple of normal USB-C cables will work with anything and everything that supports USB-C, regardless of generation. However, this does not extend to Thunderbolt, which requires a Thunderbolt-specific cable to guarantee compatibility and full speed.
A Thunderbolt-specific cable will have a USB-C connector at both ends and a lightning-bolt symbol on each, and it will be significantly pricier than a standard USB-C cable.
