USB-A and USB-C are two different types of USB connectors with distinct features:
1. Physical Design: USB-A connectors have a rectangular shape, while USB-C connectors have an oval shape and are symmetrical (reversible).
2. Reversibility: USB-C connectors can be plugged in either way, making them more convenient.
3. Size: USB-C connectors are smaller and more compact, allowing devices to be thinner.
4. Data Transfer Speeds: USB-A typically supports lower speeds (USB 2.0/3.0), while USB-C supports USB 3.1 Gen 2 and USB 4 for faster rates.
5. Power Delivery: USB-C supports Power Delivery (PD) technology for faster charging of larger devices like laptops.

USB and USB-C cables differ in several ways:
1. Physical Design: USB typically uses Type-A/B rectangular connectors, while USB-C features symmetrical oval connectors for reversible plug orientation.
2. Internal Structure: Standard USB cables contain four wires (power and data), while USB-C cables have additional wires for video output and Power Delivery (PD).
3. Compatibility: USB-C is the latest standard increasingly adopted in newer devices.
4. Performance: USB-C wiring supports faster data transfer (up to 10 Gbps) and higher power delivery (up to 100W) compared to traditional USB.

Not every usb c charging cable supports Power Delivery (PD). To support PD, a cable must meet certain specifications to ensure it can transmit sufficient power. While most cables are capable of data transfer and regular charging, to support high-power PD charging, you need to ensure that the usb c to usb c cable you choose complies with the relevant PD standards and can meet the charging requirements of your device.

USB-C cables are not necessarily interchangeable for all devices. The specific functionality depends on the cable’s specifications. Some may support charging and high-speed data, while others only support basic charging. For features like video output (DisplayPort Alt Mode) or Thunderbolt, both the cable and device must be compatible. Therefore, it’s important to check the specifications of both the cable and the device.

A USB-C cable does not have a fixed maximum speed. Typical speeds based on standards include:
1. USB 2.0: Up to 480 Mbps
2. USB 3.2 Gen 1: Up to 5 Gbps
3. USB 3.2 Gen 2: Up to 10 Gbps
4. USB 3.2 Gen 2x2: Up to 20 Gbps
For Thunderbolt 3 or 4 cables using the USB-C connector, speeds can reach up to 40 Gbps. Note that the maximum speed is limited by the lowest-performing component in the chain.
