Are modems intermediary devices?
Modem. A modem (modulator – demodulator) is an intermediary device that converts analog signals transferred over networks into digital signals and digital signals back to analog. They enable the transmission of digital data over analog mediums like telephone lines and optic fiber cables.
What are intermediate devices?
Intermediary devices interconnect end devices. These devices provide connectivity and work behind the scenes to ensure that data flows across the network. Intermediary devices connect the individual hosts to the network and can connect multiple individual networks to form an internetwork.
What is hub and its diagram?
If a packet reaches at one port, it is able to see by all the segments of the network due to a packet is copied to the other ports….Difference between hub and switch.
| Hub | Switch |
|---|---|
| A hub works at the physical layer of the OSI model. | A switch works at the data link layer of the OSI model. |
What is an end user device?

Which two devices are intermediary devices?
Intermediary devices connect the individual hosts to the network and can connect multiple individual networks to form an internetwork….Examples of intermediary network devices are:
- switches and wireless access points (network access)
- routers (internetworking)
- firewalls (security).
Is Bluetooth an intermediary device?
