    Backend Architecture and Data Processing

    TI-34 Online employs a hybrid backend architecture combining stateless serverless functions (e.g., AWS Lambda or Google Cloud Functions) for real-time computation with a centralized database for session management and historical data storage. The system processes user inputs through a tokenized parsing engine, converting mathematical expressions into abstract syntax trees (AST) for efficient evaluation. Key components include:

    - Computational Core:
    A lightweight JavaScript-based interpreter (WebAssembly-optimized for performance) executes arithmetic, logarithmic, and statistical functions with IEEE 754 floating-point precision. Advanced operations (e.g., matrix calculations, derivatives) utilize precompiled libraries to reduce processing overhead.

    - Data Storage:
    User sessions and temporary calculations are stored in in-memory caches (Redis) to minimize latency, while persistent data (e.g., saved projects or batch results) is encrypted and stored in NoSQL databases (MongoDB) with automatic sharding for scalability. Data retention policies comply with GDPR and other regional regulations, with optional export/import functionalities for user-controlled backups.

    - Security Measures:
    Input sanitization prevents injection attacks (e.g., SQL, JavaScript), while rate limiting and CAPTCHA challenges mitigate brute-force exploits. Session tokens are time-bound and invalidated after inactivity, with additional two-factor authentication (2FA) for administrative or sensitive calculations. All data transmissions adhere to TLS 1.3 standards.

    Computational Speed and Accuracy Benchmarks

    TI-34 Online achieves sub-millisecond response times for basic operations (e.g., addition, exponentiation) and <100ms for complex expressions (e.g., polynomial roots, statistical regressions), outperforming many desktop calculators in latency-sensitive environments.
