What is a "remote host"?

A "remote host" refers to a computer or server that is located away from the user, typically connected via a network, allowing users to access its resources or services over that network. This term emphasizes the separation in geography or network location between the user and the host, commonly encountered in contexts like cloud computing, remote access services, or any distributed systems architecture where resources are not located on the user's local machine.

This definition aligns with the understanding that remote hosts enable users to retrieve data, run applications, or utilize services from a distance. The other options do not encapsulate the essence of the term as well; for example, while a server hosting public websites is indeed a type of remote host, it doesn’t fully capture all instances of remote hosts which can include various forms of computers or servers. Similarly, telecommunication systems and network devices that connect local machines, while relevant in their contexts, stray from the specific concept of a "remote host" as described.
