Why is STP considered crucial in optimizing network performance in complex network topologies with multiple interconnected switches?
Spanning Tree Protocol (STP) is considered important in optimizing network performance in complex network topologies with multiple interconnected switches due to its ability to prevent loops in Ethernet networks. Loops occur when there are redundant paths between switches, causing packets to circulate indefinitely, leading to network congestion and potential broadcast storms. STP addresses this issue
Explain the concept of administrative distance in routing and its significance in selecting preferred routes.
Administrative distance in routing refers to a measure used by routers to select the best path when multiple routing protocols provide route information for the same destination. It is a important concept in computer networking, especially in the context of dynamic routing protocols and traffic forwarding. Each routing protocol assigns a numerical value to its
What are the benefits of assigning one subnet per VLAN in network organization?
Assigning one subnet per Virtual Local Area Network (VLAN) in network organization offers various benefits in terms of network security, performance optimization, and simplified network management. VLANs are a fundamental component of modern network design, allowing network administrators to logically segment a single physical network into multiple isolated broadcast domains. Each VLAN operates as a

Explain the role of routers in forwarding data packets between different networks in the TCP/IP model and why they are essential for efficient data transmission.
Routers play a pivotal role in forwarding data packets between different networks within the Transmission Control Protocol/Internet Protocol (TCP/IP) model. The TCP/IP model is a conceptual framework used for understanding how data is transmitted over a network. It consists of four layers: the Application layer, Transport layer, Internet layer, and Network Access layer. The Internet
Describe the importance of understanding full-duplex and half-duplex modes in network communication.
Understanding the concepts of full-duplex and half-duplex modes in network communication is important in the realm of computer networking, particularly in the context of physical networks and cabling devices. These modes define how data is transmitted and received between devices on a network, impacting the efficiency, speed, and overall performance of network communications. Full-duplex communication
