A router is a hardware device that operates at the network layer and is responsible for directing network traffic between different networks. It uses routing tables to determine the best path for forwarding packets. On the other hand, a brouter is a hybrid device that combines the functionalities of a router and a bridge. It can operate at both the network layer and the data link layer, allowing it to handle both IP-based networks and non-IP-based networks.Rate this question:
-
- 32.
What hardware devices does the transport layer deal with?
- A.
Gateway
Correct Answer
A. GatewayExplanation
The transport layer of the network protocol stack is responsible for managing the end-to-end communication between two devices. It ensures reliable and efficient data transfer by breaking the data into smaller segments and reassembling them at the receiving end. A gateway is a hardware device that acts as an interface between different networks. It can connect networks with different protocols or architectures, allowing data to flow between them. Therefore, the transport layer may interact with gateways to facilitate communication between devices on different networks.Rate this question:
