Difference between Router, Switch, and Hub. Send this to a friend. The following part will focus on the topic—hub vs switch vs router, aiming to clarify differences among them. A hub contains multiple ports. When a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets. Hub acts as a common connection point for devices in a network. A switch operates at the data link layer layer 2 and sometimes the network layer layer 3 of the OSI Open Systems Interconnection Reference Model and therefore support any packet protocol.
In networks, the switch is the device that filters and forwards packets between LAN segments. See more information on Network Switch and Selection Suggestions.
The router is generally located at gateways, the places where two or more networks connect. Using headers and forwarding tables, router determines the best path to forward the packets. In addition, router uses protocols such as ICMP Internet Control Message Protocol to communicate with each other and configures the best route between any two hosts.
Functions: As discussed earlier, a hub can connect multiple Ethernet devices as a single segment, whereas a switch can join multiple devices within one LAN. Device Type: The hub is the least intelligent device as it simply passes a received data packet to all the devices connected to it.
Both, the switch and router are considered as the intelligent devices as they send the received data packets to appropriate devices. Data Transmission Form: The data transmitted through a hub is in the form of an electrical signal or bits; through a switch, it is in the form of frame and packet. Through a router, it is in the form of a packet. Transmission Mode: The hub uses a half-duplex mode to exchange the data. This is in contrast to an Ethernet hub.
