What are the limitations of Classic Spanning Tree (802.1d) and how do newer versions like Per VLAN Spanning Tree (PVST) and Rapid Spanning Tree (802.1w) address these limitations?
Classic Spanning Tree Protocol (STP), defined in IEEE 802.1d, is a fundamental mechanism used in Ethernet networks to prevent loops in bridged or switched networks. However, it comes with certain limitations that have been addressed by newer versions such as Per VLAN Spanning Tree (PVST) and Rapid Spanning Tree Protocol (RSTP, 802.1w). One of the
Differentiate between IEEE 802.1Q and Cisco's Inter-Switch Link (ISL) tagging methods in VLAN trunking.
IEEE 802.1Q and Cisco's Inter-Switch Link (ISL) are two distinct methods used in Virtual Local Area Network (VLAN) trunking to carry multiple VLANs over a single link between switches. Understanding the differences between these tagging methods is crucial for network administrators to effectively manage VLANs within their network infrastructure. IEEE 802.1Q, also known as dot1q,
What is the purpose of protocols in a network, and how do they facilitate communication between devices?
Protocols in a network serve as the foundation for communication between devices by establishing a set of rules and conventions that enable devices to transmit and receive data effectively and efficiently. These protocols define how data is formatted, transmitted, received, and acknowledged within a network, ensuring that devices can understand each other's communications. One of

Does Modern Internet network protocols strictly implement the OSI model?
Modern Internet network protocols do not strictly implement the OSI (Open Systems Interconnection) model. The OSI model is a conceptual framework that defines the functions of a network protocol stack, dividing it into seven layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application. Each layer has its own specific set of protocols and functions,
