Most EHR systems today are based on which type of computer model?

• A. Hardware-software
• B. Client-server
• C. Hosted
• D. Peer-to-peer

Answer: (B)

Most EHR systems are built on a client-server model in which a centralized server hosts the database and application logic, and client devices access the system over a network. This setup provides centralized data management, strong security controls, and robust audit capabilities essential for healthcare, while allowing many users to work simultaneously and enabling reliable integration with other hospital systems. The other options describe deployment or architecture that don’t match how EHRs are typically structured: hardware-software isn’t a specific model, hosted refers to where software runs rather than how it’s organized, and peer-to-peer lacks a central data store, making governance and security much harder in a healthcare setting.
