What is the fundamental distinction between a node and a host?

Answer 1

The fundamental distinction between a node and a host is that a node is a generic term used to refer to any device or object connected to a network, whereas a host specifically refers to a device or computer system that can send or receive information over a network.

A node can be any device that is part of a network, including computers, servers, routers, switches, or even IoT devices like smart speakers or cameras. It represents an entity in the network that has a unique address. Nodes can have various functions within a network, such as storing data, performing calculations, or facilitating communication.

On the other hand, a host refers to a specific type of node that can initiate or respond to network requests. It is usually a computer or a server that provides services, data, or resources to other devices connected to the network. Hosts have unique identification within a network, such as an IP address or hostname, and are actively involved in network activities like requesting web pages, serving web content, or hosting websites.

In summary, while all hosts are nodes, not all nodes are hosts. Nodes encompass a broader range of devices, whereas hosts are specifically devices that actively participate in network communication.
