what are hubs, switches and routers
Answers
The router forwards data packets along networks. It is connected to at least two networks, commonly two LANs or WANs or a LAN and its ISP's network. Routers are located at gateways, the places where two or more networks connect. Routers use headersand forwarding tables to determine the best path for forwarding the packets, and they use protocols to communicate with each other and configure the best route between any two hosts.
What is a Switch?
In networks the switch is the device that filters and forwards packets between LAN segments. Switches operate at the data link layer (layer 2) and sometimes the network layer (layer 3) of the OSI Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs.
Finally, what is a Hub?
A hub is a common connection point for devices in a network. Hubs connect segments of a LAN. It contains multiple ports so 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.
WHAT IS A 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.
WHAT IS A 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.
WHAT IS A 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.
