Which of the following is a Physical Layer standard?

This standard includes details about cables, connectors, signal types, and how devices connect and communicate at the hardware level.

Key points about Ethernet (IEEE 802.3):

• Defines physical media types (like twisted pair, fiber optic)


• Controls how bits are placed on the wire


• Works at the lowest levels of network communication


• Used in most LAN (Local Area Network) setups

Because it manages how devices physically connect and send signals, Ethernet is a standard related to the Physical Layer.
