What is the simplest network hardware device used to connect several computers?

• A. Network hub
• B. Switch
• C. Router
• D. Modem

Answer: (A)

Connecting several computers in the simplest way is through a basic network hub. A hub acts as a central junction with multiple ports and simply repeats any incoming signal to all the other ports. There’s no smart filtering or decision-making about where data should go, so it’s the most straightforward way to put multiple machines on one local network.

In contrast, a switch adds intelligence by learning which devices are on the network and only sending data to the correct destination port, which helps prevent unnecessary traffic. A router connects different networks and routes traffic between them, not just within a single LAN. A modem links to an internet service provider and converts signals for access to the wider internet, not for connecting several computers together on a LAN. So, for the simplest, non-intelligent shared connection, a hub is the best fit.
