Switchs Flashcards
What is a switch?
A switch is a network device that connects devices within the same local area network (LAN) and forwards data based on MAC addresses.
What is the difference between a hub and a switch?
A hub broadcasts data to all connected devices, while a switch sends data only to the specific device it is intended for, reducing collisions.
What is VLAN in a switch?
A VLAN (Virtual Local Area Network) allows logical segmentation of a network into smaller, isolated subnetworks, even if devices are physically connected to the same switch.
How does a switch improve network performance?
A switch reduces collisions and improves performance by directing traffic to the correct device, rather than broadcasting it to all devices.
What is a Layer 3 switch?
A Layer 3 switch can perform both switching and routing functions, forwarding traffic based on IP addresses.
What is the purpose of QoS in switches?
Quality of Service (QoS) in switches prioritizes certain types of network traffic to ensure critical data, like voice or video, is transmitted with higher priority.
What are PoE switches?
PoE (Power over Ethernet) switches provide electrical power to devices like IP cameras and phones over the same Ethernet cable used for data transmission.
How does a managed switch differ from an unmanaged switch?
A managed switch allows for configuration, monitoring, and troubleshooting, while an unmanaged switch operates without user intervention.
What is MAC address learning in a switch?
MAC address learning is the process by which a switch builds a MAC address table by learning the source MAC address of incoming frames.
What is broadcast storm in switching?
A broadcast storm occurs when there are too many broadcast packets sent on a network, which can overwhelm switches and degrade network performance.
