Understanding Network Devices for Connecting Nodes

The question asks about a device specifically used to connect multiple 'nodes' to a network. In computer networking, a 'node' is any device connected to the network, such as computers, printers, or servers. Different network devices serve different purposes in building and managing networks.

Exploring Different Network Devices

Let's look at the functions of the devices listed in the options:

• Router: A router is a device that connects different networks together, such as connecting your home network to the internet. It routes data packets between these different networks based on IP addresses. It's primarily used for inter-network communication, not just connecting multiple nodes within a single network segment.
• Repeater: A repeater is used to regenerate a network signal to extend its range. It takes a weak signal and retransmits it at a higher power level. It doesn't connect multiple devices directly; it extends the reach for existing connections.
• Modem: A modem (Modulator-Demodulator) is used to convert digital signals from a computer into analog signals for transmission over traditional telephone lines or cable lines, and vice versa. It's essential for connecting to the internet via certain types of connections but doesn't connect multiple local network nodes to each other.
• Hub: A hub is a basic networking device that connects multiple Ethernet devices or nodes together. When a data packet arrives at one port of a hub, the hub broadcasts or copies that packet to all other ports. This allows all connected devices (nodes) to communicate with each other, essentially creating a single shared network segment. Hubs are simple and less intelligent than switches or routers.

Identifying the Device to Connect Multiple Nodes

Based on the functions described, the device specifically designed to connect multiple nodes within the same network segment is a hub. It provides a central connection point for all the network devices.

Therefore, a device used to connect multiple nodes to a network segment is a hub.
