Which of the following statement is true?a)A switch creates a single c...
Explanation:
Switch:
A switch is a networking device that operates at the data link layer of the OSI model. It is used to connect multiple devices within a local area network (LAN). Switches use MAC addresses to forward data packets to the correct destination device.
Collision Domain:
A collision domain is a network segment or LAN where collisions can occur. Collisions happen when two devices try to transmit data on the same network segment at the same time. In Ethernet networks, collisions can cause data loss and network congestion.
Broadcast Domain:
A broadcast domain is a network segment or LAN where broadcast packets are sent. Broadcast packets are sent to all devices on the network segment. Devices within the same broadcast domain can directly communicate with each other using broadcast packets.
Router:
A router is a networking device that operates at the network layer of the OSI model. It is used to connect different networks together and route data packets between them. Routers use IP addresses to determine the best path for forwarding packets to their destination.
Explanation of Options:
a) A switch creates a single collision domain and a single broadcast domain. A router creates a single collision domain.
- This statement is incorrect because a switch actually creates separate collision domains, not a single collision domain. A router does not create a collision domain.
b) A switch creates separate collision domains but one broadcast domain. A router provides a separate broadcast domain.
- This statement is correct. A switch creates separate collision domains for each of its ports, which reduces the likelihood of collisions. However, it only creates one broadcast domain. A router, on the other hand, provides a separate broadcast domain for each of its connected networks.
c) A switch creates a single collision domain and separate broadcast domains. A router provides a separate broadcast domain as well.
- This statement is incorrect because a switch creates separate collision domains, not a single collision domain. However, it is true that a switch can create separate broadcast domains.
d) A switch creates separate collision domains and separate broadcast domains. A router provides separate collision domains.
- This statement is incorrect. A switch creates separate collision domains, but a router does not provide collision domains. Routers route packets between networks based on their IP addresses.
Therefore, the correct statement is option b) A switch creates separate collision domains but one broadcast domain. A router provides a separate broadcast domain.
