Answer Description

USB-C connectors are known for their reversibility, meaning they can be inserted with either side facing up, which is a significant improvement over previous USB designs. This convenience trait, along with their ability to carry power and data, makes them widely used in current-generation electronics. MicroUSB and MiniUSB, although also used for charging and data transfer, are not reversible. USB-A is not commonly used in modern smartphones due to its larger size and non-reversible design.
