The device that connects multiple network segments and forwards data packets based on their IP addresses is called a ____________. 

1. Switch 

2. Router 

3. Hub 

4. Modem

b) Router

Detailed answer by teachoo

-lock-

Let’s go through each of the options and see why they are correct or incorrect.

a) Switch: This option is incorrect because a switch forwards data packets based on their MAC address, not their IP address. A MAC address is a unique identifier of a device on a network, while an IP address is a logical address that identifies a device on an inter-network.

b) Router: This option is correct because a router forwards data packets based on their IP address, which is the requirement of the question. A router can connect multiple network segments and perform various functions such as routing, filtering, security, etc.

c) Hub: This option is incorrect because a hub broadcasts data packets to all the connected devices, not to the specific destination device based on their IP address. A hub does not filter or process the data packets, which can cause collisions and congestion on the network.

d) Modem: This option is incorrect because a modem modulates and demodulates the signals between analog and digital formats, not forwards data packets based on their IP address. A modem enables communication over telephone lines or cable networks, not connecting multiple network segments.

So, the correct answer is b) Router.
