This video discusses how basic network topologies like full mesh and star are impractical for large networks due to high cost and link requirements, necessitating the use of switched networks composed of interlinked nodes called switches. Switched networks are primarily categorized into Circuit Switching, where a dedicated path is established and resources are reserved for guaranteed bandwidth and consistent delay, and Packet Switching. Packet switching, the basis of the modern Internet (IP), breaks data into small packets and is more efficient as resources are used only on demand; it can operate as Datagram networks, where packets take independent routes and arrival order is not guaranteed, or Virtual-Circuit networks, where all packets follow the same pre-established logical path. Message switching, an older and largely obsolete technique, treats the entire message as one unit using a store-and-forward mechanism, leading to potentially high delays
