Google Groups is an online discussion group and collaboration management service offered by Google. It allows users to create, manage, and participate in discussion groups on various topics. Each group has its own email address, making it easy for members to exchange messages. Google Groups offers features such as storing and archiving discussions, the ability to moderate contributions, and customization options for privacy and access settings. It is particularly useful for work teams, online communities, and organizations looking to centralize communications and promote collaboration among members. By integrating discussion groups into the Google ecosystem, users benefit from a seamless experience with other Google services, such as Gmail and Google Drive.
