How does Viber and WhatsApp work - briefly?

Both Viber and WhatsApp are messaging applications that utilize end-to-end encryption to ensure the security of user communications. They operate by sending messages through the internet rather than traditional SMS channels, enabling multimedia sharing and real-time communication features.

How does Viber and WhatsApp work - in detail?

Viber and WhatsApp are two of the most popular messaging applications in the world, facilitating communication through text, voice calls, and video conferencing. Understanding how these platforms operate involves delving into their technological underpinnings, security measures, and user experience enhancements.

At their core, both Viber and WhatsApp rely on internet connectivity to transmit data between users. They utilize end-to-end encryption to ensure that messages and calls remain private and secure. This means that only the intended recipients can read or listen to the communication, adding a layer of protection against eavesdropping and hacking attempts.

Viber, developed by Viber Media, was one of the first applications to offer free voice and video calls over the internet. It uses Voice over Internet Protocol (VoIP) technology to convert audio signals into digital data packets that can be transmitted over the internet. These data packets are then sent from one device to another, allowing for real-time communication without incurring traditional phone charges. Viber also supports group chats and multimedia messaging, enabling users to share images, videos, and documents with ease.

WhatsApp, owned by Facebook Inc., follows a similar approach but has expanded its features to include status updates, story sharing, and business accounts. It utilizes the Extensible Messaging and Presence Protocol (XMPP) for messaging and Signaling System No. 7 (SS7) for voice calls. WhatsApp's end-to-end encryption is implemented using the Signal protocol, which is widely regarded for its robust security features. Additionally, WhatsApp offers a desktop application and web client, allowing users to stay connected across multiple devices.

Both platforms have undergone significant updates to improve user experience and enhance functionality. Viber has introduced features like secret chats, which offer additional layers of privacy by setting messages to self-destruct after a specified time. WhatsApp, on the other hand, has implemented features such as disappearing messages and view once media, providing users with more control over their shared content.

In terms of infrastructure, Viber and WhatsApp maintain servers around the world to ensure reliable and fast communication. These servers handle the routing of messages and calls, ensuring that data is transmitted efficiently between users. The applications also employ push notifications to alert users of new messages or incoming calls, even when the app is not actively in use.

Despite their similarities, Viber and WhatsApp have different approaches to monetization. While both platforms were initially free to use, WhatsApp has introduced business-oriented features that allow companies to communicate with customers directly through the app. Viber, however, relies more on in-app purchases for stickers and other digital content, as well as partnerships with businesses for promotional activities.

In conclusion, Viber and WhatsApp operate on sophisticated technologies that enable secure, real-time communication over the internet. Their use of end-to-end encryption ensures privacy, while their continuous updates and feature enhancements cater to the evolving needs of users. By leveraging robust infrastructure and advanced protocols, these platforms have become indispensable tools in today's digital landscape.
