Difference Between Hub and Modem

We have complimentary equipment like hubs and modems in most modern houses, with two or more computers and Internet connections, which usually don’t communicate with but assist to maintain the network.

Hub vs Modem

The main difference between Hub and Modem is that basically if you wish to link two or more computers, a hub is used. A hub is an interface between your computers and a modem because it allows your computers to communicate to the modem and to connect to the Internet whereas, A modem is what enables us to connect to the internet and a modem may be used as frequently as a single computer.

Hub vs Modem

Hubs are networking devices used to link numerous devices in a network using a physical layer of the OSI architecture.

Put another way, it translates digital data from your computer into analog signals that can be transferred over cables, and it can also translate incoming analog signals into digital data that your computer can comprehend.

What is Hub?

A hub is a virtual networking device that connects a network’s numerous PCs or other network devices.

Hub is used to link LAN segments. If a packet reaches a single port, it gets duplicated to all other ports stored in the hub.

When the frame is received, it is transferred after amplification to the port of the target computer.

What is Modem?

Modem or “Modulator-Demodulator,” is a component of hardware that permits an Internet-based computer or another device like a router or switch.

The early modems were “wired,” thus a telephone number was needed to be dialed to connect to an ISP.

This period is in bits per second (bps). Another method to define modem speed is to count the number of times a modem sends a new signal in a given period as the number of times the signal state changes in a unit of time.

Main Differences Between Hub and Modem

  1. The transmission mode for a hub is Half Duplex whereas, the transmission mode of a Modem is Full Duplex.
  2. The maximum speed of a Hub is 10Mbps whereas, the maximum speed of a Router is 56.6Kbps.
Difference Between Hub and Modem


A modem is an interface between a digital and analog network, whereas a hub is entirely digital. In today’s environment, every home must have a Modem or a Hub.

A router needs to be connected to a device that can transport your digital traffic on whatever sort of Internet connection you have and that device is the modem.
