The service uses internet connectivity, either through Wi-Fi or cellular data, to send and receive messages, voice calls, and video calls. This ensures that users’ conversations remain private and secure. Messages are sent using end-to-end encryption, meaning only the sender and recipient can read the messages, and no third parties, including WhatsApp, can access them. Once registered, they can start messaging other users who are in their contacts list. To use WhatsApp, users must first download the app on their mobile device and create an account using their phone number. In February 2014, Facebook acquired WhatsApp for $19 billion, making it one of the most expensive acquisitions in tech history.
The app was created in 2009 by two former Yahoo employees, Jan Koum and Brian Acton, who wanted to develop a messaging service that was secure, fast, and easy to use. WhatsApp is a popular messaging application that enables users to send text and voice messages, make voice and video calls, and share files and locations with other users.
