Odd One Out:
The odd one out is option D: TCP.
Explanation:
TCP stands for Transmission Control Protocol, which is a protocol used for establishing and maintaining network connections. The other options, Bridges, Routers, and Gateways, are all network devices or technologies, whereas TCP is a protocol.
Details:
Below are the details of each option:
- Bridges: Bridges are network devices that connect multiple local area networks (LANs) together. They operate at the data link layer of the OSI model and are used to extend network coverage and improve network performance.
- Routers: Routers are network devices that forward data packets between different networks. They operate at the network layer of the OSI model and use routing tables to determine the best path for data transmission.
- Gateways: Gateways are devices that enable communication between networks with different protocols or architectures. They can perform protocol translation, data format conversion, and other necessary tasks to allow different networks to communicate with each other.
- TCP: TCP is a protocol that provides reliable, ordered, and error-checked delivery of data packets over an IP network. It is used in conjunction with the Internet Protocol (IP) to establish connections between devices and ensure the reliable transmission of data.
In summary, Bridges, Routers, and Gateways are all network devices, while TCP is a protocol used for data transmission. Therefore, TCP is the odd one out in this context.
