Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Consider a 10MB file transfer in a 32-bit processor system where the maximum transfer limit is 128KB per interrupt. How many interrupts are needed?

💡 Hint: Convert MB to KB and divide by the transfer limit.

Challenge 2 Hard

Analyze the impact of using burst mode for real-time applications that require continuous data processing.

💡 Hint: Consider how frequently the CPU needs to process tasks simultaneously.
