Simply put, a node is a networking device with an IP address that aids in connectivity with other nodes.
I'm not sure you explain it poorly or confused between term "node" and "server" when the context is Bitcoin wallet. When people say "networking device", they usually refer to device such as router, switch or wifi receiver. Obviously you can't run Bitcoin full node on such device.
I also thought that he's talking about networking instead of Bitcoin and got suspicious on his activity after browsing though his post history.
After a few searches, I found out that his post is suspiciously similar to this answer from a Q&A website.
