ARP – Quick Answer

ARP stands for Address Resolution Protocol.

This is a networking system that helps devices find each other on a local network, like WiFi.

What Is the Meaning of ARP?

In simple words, ARP is a helper system inside a network.

Its job is to make sure devices know exactly who they are talking to. Every device has two main identifiers:

An IP address (like a house number)
A MAC address (like a fingerprint)

ARP connects these two.

Real-Life Example

Imagine you ask for a friend’s house in a big neighborhood. Someone shows you the exact house.
That “someone” is basically ARP.
