ARP role in networking?

Address Resolution Protocol (ARP) plays a crucial role in networking, especially in facilitating communication between devices within a local network. In the context of networking courses like the "100% Job Guarantee Course" or "Job Guarantee Course," understanding ARP becomes paramount for students aiming for success in the field.
ARP serves as the bridge between the logical addresses used by network protocols, such as IP addresses, and the physical MAC addresses of devices on the network. When a device wants to communicate with another device on the same network, it first checks its ARP cache to see if it already knows the MAC address corresponding to the IP address of the destination device.
