Which Two Statements Describe Intermediary Devices? (Choose Two.)

Intermediary devices

The infrastructure is like the platform where the whole network is established and it is like the cable connecting one computer to the other. The component of the network is three in total:

• End devices.
• Intermediary devices.
• Network media.

In this article, you are going to learn about intermediary devices. The hardware work with the component of the network that is visible such as the hub, router, switches. To know more about the intermediary devices read the article to the end!

What are the intermediary devices and how does it work?

The intermediary devices are built to move the data from one side to the other computer which is connected to the network.it is a medium for the connection for the other nodes and also manages the background services which ensure that data is transferred accurately and efficiently.

The data flow through the intermediary device is maintained with the help of IP address, port address the physical address (MAC address), and the complete knowledge of the interconnected devices in a network. The switching tells the effective path for the message that flows through them.

The working or function of the intermediary devices are in the following:

• The damping (which increases the response and makes the noise less) has been reduced through regeneration and retransmission happen with the help of the intermediary devices.
• For the transmission of the message, the source and the destination address are kept by the intermediary devices and also have the information of the path that exists in the network.
• The faults are the network detects by the intermediary devices.
• During the data transfer, the correction in the error is also done by these devices.
• The transfer rate and the response time are maintained by the devices.
• The path, setup of the messages with their priorities are done by the intermediary devices.
• The security is also provided by the devices by permitting and denying the data through the network.

Some of the examples of the intermediary devices are given below:

Router:

The router in the network is responsible for the data motion and shows the path to the data in the computer network. The data transfer and the flow rate among the two or more subnet who are not of the same network address are maintained by the router. The best possible path for data is directed by the router.

Modem:

A modem is responsible for modulation (convert the analog signal to digital) and demodulation (convert the digital signal to the analog). A modem allows the transmission of digital signals through telephones and fiber optics which are analog mediums.

Hub:

The hub works at the physical layer of OSI and acts as the connector for ethernet ports, and the bandwidth among the connected devices is also maintained by it.

Which two statements describe intermediary devices? (Choose two.)

• the encapsulation is initiated by the intermediary devices.
• Generate the data.
• The path is directed by the intermediate devices. The devices connect the individual to the host.
• The data has been changed by these devices.

Answer: the applications are responsible for data generation, modification in the data, and the initiation of the encapsulation.
