WhatsApp Groups are a feature within the WhatsApp messaging app that allows users to create a space for multiple participants to communicate simultaneously. Each group can have up to 256 members, making it easy for friends, family, or colleagues to share messages, photos, and videos in one place. Members of a WhatsApp Group can send messages that everyone in the group can see, fostering discussions and collaboration. Group admins have the ability to manage participants, including adding or removing members, ensuring that the group remains organized and relevant to its purpose.
