Introduction :- Router, switch, and hub are networking devices. These are used for data transmission and communication in computer networks. The work of these three is different.
Router :-
A router is a networking device in which many networks are connected, and it sends data packets from one network to another. Router provides internet to customers through ISP. Router sends data packets using IP address.
Features of Router :-
1. Data Routing: The router tells the way to send data packets to the right destination.
2. Network Security: The router has security features like a firewall. Which makes data transfer secure.
3. Multiple Networks: Routers can connect with many networks.
4. DHCP Server: Router works like a DHCP server. It provides IP addresses to the devices.
Use of Router :-
1. Home Networking: A router is used to access the Internet.
2. Office Networking: A router is used to connect the network of offices to the Internet.
3. Virtual Private Network (VPN): Router helps in connecting to Virtual Private Network.
Switch :-
Like a router, a switch is a network device. In which the switch sends data packets from one network to many devices. It creates a MAC address to send data packets to the devices. The work of the switch network is also done to secure the network.
Features of Switch :-
1. Data Switching: Switch creates MAC address to send data packets to the right devices. Switch increases the speed of data transmission.
2. VLAN: Switch supports VLAN. Due to this the network gets divided into different parts.
3. Port Management: Switch has many ports. Which makes it easy to connect devices.
Use of Switch :-
1. Local Area Network (LAN): The work of a switch is to connect devices in a LAN. And works to send data.
2. Data Center: Switches are used to connect servers in data centers and to connect storage devices.
3. Office Network: Switches are used to connect computers, printers, and many devices in the office network.
Hub :-
Just like a router and switch, a hub is also a network device. It works to send data to all the devices connected in the hub. The hub works as a central connection point. And works to simplify data transmission. The hub works to send data packets to all ports.
Features of Hub :-
1. Data transmission: The hub sends data packets to all ports.
2. Simplicity: The design of the hub is very simple, which makes it easy to use.
3. Low cost: It costs less to use a hub. Hubs are used for small networks.
4. Ports: Hubs have many ports through which many devices can be connected simultaneously.
Use of Hub :-
1. Small Network: Hub is used to connect devices in a small network.
2. Provisional Network: Hub is used to send data in a temporary network.
3. Device Connection: Hub is used to connect multiple devices simultaneously.
Conclusion :-
Router, switch, and hub are all essential devices of networking. All three fulfill the requirement of networking. A router works to connect multiple networks. Switch works to send data to the correct destination; similarly, a hub divides data packets into multiple ports.
Through these three devices, the speed of data transmission is fast, and data is secure. Therefore, they are used, keeping in view the requirement of networking.
