Detailed explanation-1: -A hub connects multiple computers together in a Local Area Network (LAN). All information sent to the hub is then sent through each port to every device in the network.
Detailed explanation-2: -A router is a device that connects two or more packet-switched networks or subnetworks. It serves two primary functions: managing traffic between these networks by forwarding data packets to their intended IP addresses, and allowing multiple devices to use the same Internet connection.
Detailed explanation-3: -Hub. A hub is a physical device used to join multiple devices on the same LAN. For example, a laptop, desktop computer and printer can connect into a hub’s ports with Ethernet cables and be part of the same local network.
Detailed explanation-4: -A network switch is a physical device that operates at the Data Link layer of the Open Systems Interconnection (OSI) model–Layer 2. It takes in packets sent by devices that are connected to its physical ports, and forwards them to the devices the packets are intended to reach.
