A physical link is a direct connection between two or more devices, such as computers, over a distance. It involves the transmission of data through a physical medium, such as a wire, cable, or wireless signal.
Physical links are essential for data communication as they enable devices to directly exchange information with each other. They facilitate the transfer of data bits across the network, allowing devices to communicate and share resources.
Some common physical links include:
Ethernet cables: These cables connect computers in a local area network (LAN).
Bluetooth: This wireless technology allows devices to communicate over short distances.
Radio waves: These waves are used in wireless communication systems like cellphones and Wi-Fi.
Fiber optic cables: These cables transmit data using light signals, offering high bandwidth and reliability
