Explanation:

The typical physical connector used for a Gigabit Ethernet port is an RJ-45. This connector is standard for network cabling and provides the necessary performance for Gigabit Ethernet, which is also known as 1000BASE-T. RJ-45 connectors are used because they can support higher data rates compared to other connectors like RJ-11 or RJ-9, which are commonly used for telephone connections, and DB-25, which is an older serial port connector not suitable for high-speed Ethernet connections1.
