What's the difference between hub, switch and router as used in networt
Answers
Answer:
Hub Vs. Switch
A hub works on the physical layer (Layer 1) of OSI model while Switch works on the data link layer (Layer 2). Switch is more efficient than the hub. A switch can join multiple computers within one LAN, and a hub just connects multiple Ethernet devices together as a single segment. Switch is smarter than hub to determine the target of the forwarding data. Since switch has a higher performance, its cost will also become more expensive.
Switch Vs. Router
In the OSI model, router is working on a higher level of network layer (Layer 3) than switch. Router is very different from the switch because it is for routing packet to other networks. It is also more intelligent and sophisticated to serve as an intermediate destination to connect multiple area networks together. A switch is only used for wired network, yet a router can also link with the wireless network. With much more functions, a router definitely costs higher than a switch.
Hub Vs. Router
As mentioned above, a hub only contains the basic function of a switch. Hence, differences between hub and router are even bigger. For instance, hub is a passive device without software while router is a networking device, and data transmission form in hub is in electrical signal or bits while in router it is in form of packet.
HUB
A hub is an electronic device that connects multiple nodes in a network and sends and receives data from all the connected nodes. A hub contains multiple ports that are used to connect multiple nodes. This means that the data received by the hub is sent to all the computer that are connected with the hub.
ROUTER
A router is a networking device that connects multiple physical networks. The main job of a router is to prevent data broadcast. Of directs the data to the correct network and path based on the data properties.
SWITCH
A switch is an electronic device that connects multiple nodes and send data only to the intended node. It is an intelligent hub as it analyses the received data and sends it to the intended computer.
