A router is a networking device that forwards data packets between computer networks.

• Routers operate at the network layer (Layer 3) of the OSI model.

• They use routing tables to determine the best path for data packets to reach their destination.

• Routers can connect multiple networks together, such as LANs and WANs.

• They provide network address translation (NAT) to allow multiple devices to share a single public IP address.

• Examples of routers include Cisco routers, TP-Link router...read more

Switches and hubs are networking devices used to connect multiple devices in a network.

• Switches operate at the data link layer of the OSI model and make forwarding decisions based on MAC addresses.

• Switches provide dedicated bandwidth to each connected device, allowing simultaneous communication.

• Hubs operate at the physical layer and simply broadcast incoming data to all connected devices.

• Hubs share the available bandwidth among all connected devices, leading to collisions and...read more

IP stands for Internet Protocol.

• IP is a set of rules that governs how data is sent and received over the internet.

• It is responsible for assigning unique addresses to devices connected to a network.

• IP addresses can be either IPv4 (e.g., 192.168.0.1) or IPv6 (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334).

• IP is a fundamental protocol in the TCP/IP suite, which is the foundation of the internet.

• IP packets contain both the source and destination IP addresses, allowing routers to ...read more
