Hubs
Layer 1 device, known as a multi-port repeater. Connects collision domains, making them bigger
What are the types of hubs
passive, active, and smart
Passive Hub
repeats suignal without amplification
Active Hub
boosts signal to overcome cable length limitations
Smart Hub
like an active hub with enhanced features like SNMP for remote configuration
Bridges
Layer 2 device
Analyzes source MAC addresses to populate MAC address table
Use destination MAC addresses to decide where to forward traffic
Divide collision domains, improving both network security and efficiency
Switches
Operates at layer 2
Modern replacement for hubs often referred as multiport bridge
Each port operates in its own collision domain
Learns MAC addresses and uses MAC address table to forward traffic
improves traffic management, minimizes collisions, and enhances security
supports full duplex, enabling simultaneous two-way communication without interference
Routers
Works in Layer 3
Use IP addresses to direct network traffic
divide broadcast domains to improve overall network performance
offer multiple interface types for flexible and versatile connections
Layer 3 switches (Multilayer switch)
Function at layer 3, with each port acting as its own broadcast domain
integrate the roles of both switches and routers
well suited for internal network routing, but not ideal for large scale routing tasks
