Difference between host and node?

Question

Computer networks

Node - any device that has ip
Host - MUST be a server that has a domain

The client may not have a domain name. And the server has it. That is, the server is the host. Is a node both?

Answer 1

Wikipedia.

A network node is a device connected to other devices as part of a computer network. Nodes can be computers, mobile phones, PDAs, and special network devices such as a router, switch, or hub

Host - any device that provides services in the "client-server" format in server mode over some interfaces and is uniquely identified on these interfaces.

Briefly:
a network node is any network device
Host is a terminal device that provides services

Answer 2

If your question is: "I correctly understood that they are no different", then here:
ip is not a domain, a domain is not ip
Example ip: 127.0.0.1 (local ip)
Example domain: yandex.ru (Yandex domain)
