Telegram Groups are chat spaces within the Telegram messaging app where users can communicate with multiple people at once. These groups can have up to 200,000 members, making them suitable for communities, organizations, or large gatherings. Users can share messages, photos, videos, and files, fostering collaboration and discussion among members. Groups can be either public or private. Public groups are open to anyone and can be found through search, while private groups require an invitation to join. Administrators can manage group settings, control membership, and moderate discussions to ensure a positive environment for all participants.
