WhatsApp is a popular messaging app used by millions of people around the world to communicate with each other. The app allows users to send messages, photos, videos, audio recordings and other files to each other in real time. It also provides a platform for group chat and voice calls.
WhatsApp works by using an internet connection on the user’s device to send messages between users. This connection can be through a Wi-Fi network or a cellular data plan.
All messages sent through WhatsApp are encrypted, meaning that only the sender and recipient can read them. This ensures that no one else can access the messages.
When you send a message through WhatsApp, it is sent over an encrypted connection to another user’s device where it is decrypted and displayed. If you are sending a picture or video, it is first compressed into a smaller size before being sent over the internet. This helps to reduce the amount of data that is used when sending images or videos.
WhatsApp also allows users to make voice calls over their internet connection. When making a voice call, both parties must be connected to the internet in order for them to connect with each other. The call will then be routed through WhatsApp’s servers before being connected to the other person’s device.
Conclusion:
In conclusion, WhatsApp is an incredibly useful tool for communicating with people all around the world. It uses an encrypted connection to send messages between users and allows for voice calls as well as group chats. By compressing images and videos before sending them over the internet, WhatsApp helps reduce data usage while still providing high quality pictures and videos.
