A WhatsApp Group is a feature within the WhatsApp messaging app that allows multiple users to communicate in a single chat. Users can send text messages, images, videos, and voice notes to all group members simultaneously. This makes it easy for friends, family, or colleagues to stay connected and share information. Groups can have up to 256 participants, and the group admin has the ability to manage members and settings. Notifications can be customized, allowing users to mute conversations if needed. Overall, WhatsApp Groups facilitate organized communication among larger groups of people.
