Which device establishes a temporary connection between the source and...
Device that establishes a temporary connection between the source and the destination for communication:
There are two possible options for this question: Hub and Switch. Let's discuss both of these devices and their functions:
1. Hub:
- A hub is a basic networking device that connects multiple devices in a network.
- It operates at the physical layer (Layer 1) of the OSI model.
- When a device sends data to a hub, it broadcasts the data to all devices connected to it.
- The hub does not make any intelligent decisions regarding where the data should be sent, it simply forwards the data to all connected devices.
- Since it broadcasts the data to all devices, it can cause congestion and collisions in the network.
2. Switch:
- A switch is a more advanced networking device that connects multiple devices in a network.
- It operates at the data link layer (Layer 2) of the OSI model.
- When a device sends data to a switch, the switch examines the destination MAC address of the data.
- It then forwards the data only to the device with the corresponding MAC address, instead of broadcasting it to all devices.
- This helps in reducing congestion and collisions in the network, as data is only sent to the intended destination.
So, the correct answer is D: Both a & b (Hub and Switch).
- Both a hub and a switch can establish a temporary connection between the source and the destination for communication.
- However, it is important to note that switches are more commonly used in modern networks due to their ability to make intelligent forwarding decisions based on MAC addresses.
