Cyber Security for Absolute Beginners - 2022 Edition - Part 02 - Hubs, Switches, and Routers

The video tutorial explains the roles and differences of networking devices: hubs, switches, and routers. Hubs are basic devices that broadcast messages to all connected devices, leading to performance issues. Switches and routers are more intelligent, directing messages only to intended recipients. Switches connect devices within a network using MAC addresses, while routers connect different networks using IP addresses and offer additional features like firewall protection.
