This system context diagram visualizes a  social media platform and its external components: User, Advertisers, and the Bank. The interaction of the social media platform and user is easy: The platform sends the user a feed of daily comments from others. Users give some information about themselves, such as username, password, and date of birth. Advertisers’ entities represent those who place ads on the platform. The social media platform shares user data for targeted ads. The social media platform earns money from advertisers, sending revenue to the bank.
