What is the role of ARP in computer networking, and why is it essential for communication between hosts on a network?
Address Resolution Protocol (ARP) plays a crucial role in computer networking by mapping IP addresses to MAC addresses. In a network, hosts communicate using IP addresses, which are logical addresses assigned to devices for network communication. However, at the data link layer, devices use MAC addresses to identify each other. The ARP protocol bridges this

How does the Address Resolution Protocol (ARP) contribute to effective communication across VLANs?
Address Resolution Protocol (ARP) plays a crucial role in facilitating effective communication across Virtual Local Area Networks (VLANs) by enabling devices within different VLANs to communicate with each other. VLANs are used to logically segment a network into multiple broadcast domains, enhancing security and efficiency. However, communication between devices in different VLANs requires a mechanism
Differentiate between Local Area Networks (LANs) and Wide Area Networks (WANs), including their respective functions and typical use cases.
Local Area Networks (LANs) and Wide Area Networks (WANs) are two fundamental types of computer networks that form the backbone of modern communication systems. Understanding the differences between LANs and WANs is crucial in comprehending how data is transmitted and shared within and between organizations, homes, and the internet at large. A Local Area Network
