Answer:
Device B is Router.
Explanation:
Router is the device that is used to connect different networks to communicate with each other to make possible for all devices of all networks to communicate with each other that are connected to that particular network.
In above case, Device A is 8 port switch that makes a network of 8 different computers. Device C is a 4 port hub that is connected with 4 computers. Both Device A and Device C are different Networks, router is used to connect both all devices of both networks so that they can communicate each other. So the Device B should be router.
<em>r = 15 cm</em>
<em>formula</em>
<em>V = πr²×h/3</em>
<em>replace</em>
<em>4950 = 22/7×r²×21/3</em>
<em>4950 = 22/7×r²×7</em>
<em>4950 = 22×r²</em>
<em>r² = 4950/22</em>
<em>r² = 225</em>
<em>r = √225</em>
<em>r = √15²</em>
<em>r = 15 cm</em>
Answer:
Explanation:
Router. A router is a networking device typically used to interconnect LANs to form a wide area network (WAN) and as such is referred to as a WAN device. IP routers use IP addresses to determine where to forward packets. An IP address is a numeric label assigned to each connected network device.
