Information system principle: WhatsApp
WhatsApp is the most used messaging application in the world ,it enable user to to send text messages ,make voice and video call ,share photos and videos .the paper were working on today objective is to explore the database ,software and hardware that WhatsApp use and how people are using it plus the concerns with privacy and security of the app .
Hardware:
1-user -side hardware:
-smartphone, tablet and computer: WhatsApp operate on smartphone as a primary hardware, it did expand on table and computer.
-microphone and camera: this hardware is used by WhatsApp to send voice notes, photos and videos
-internet connection: WhatsApp rely on the internet to function and operate, especially using wifi router and cellular connection.
2-sever hardware:
Data center: for WhatsApp to function properly it rely on servers that store and processes data

Operating Systems: WhatsApp rely on operation systems like iOS, android, windows and Mac OS to function, this software is the key connection between the software and hardware necessary for WhatsApp app to work.
Backend Software:
1-whatsapp backend is written in Erlang, a real time software used to manage billions of users efficiently
XMPP Protocol: WhatsApp use (xmpp) for real time communication, it's one of the most important elements of WhatsApp messaging system
Encryption Software: WhatsApp claim to use end -to-end encryption mean only the users end can read the messages
Database Management Systems:whatsappp use SQLite, a software that allow users to store chat history, photos, videos and settings
Database Involved in WhatsApp:
SQLite: WhatsApp use SQLite to store media, chat, and setting on user device
Server-Side Databases: WhatsApp servers use database to save information such, user phone number, profile picture and connection logs but the actual content are not saved in the server database because of end-to end encryption
