Definition

In technological and computing contexts, the term “host” has multiple meanings:

  1. Computer Networking: In computer networks, a host is a machine, often a computer or server, that provides resources, services, or applications to other devices on a network. These hosts use networking protocols to communicate with other hosts.
  2. Online Communications: In Internet communications, such as chat rooms, a host (or moderator) is an individual who manages the conversation, ensuring adherence to guidelines and managing user interactions.

Examples

Computer Networking Host Example

  • Web Server: A web server that hosts websites and provides web pages to users’ browsers when requested.
  • File Server: A computer that hosts and manages files, enabling users to store and access shared files.
  • Mail Server: This host manages and distributes emails; Gmail and Outlook servers are prominent examples.

Online Communications Host Example

  • Chat Room Moderator: A person managing a chat room on platforms like IRC or Discord, ensuring rules are followed and moderating discussions.
  • Webinar Host: Responsible for managing an online webinar session, facilitating discussions, and handling questions from participants.
