Advancements in IoT-Based Healthcare Monitoring and Memory Hierarchy in Computing: A Comprehensive Analysis of Smart Medical Devices and Digital Memory Systems

IoT-integrated healthcare has contributed greatly to patient monitoring and medical diagnostics. This study focuses on the design of IoT-based healthcare monitoring devices, specifically the Telecare-ECG Monitor, and the improvement of remote patient care. The report covers the technical aspects of microprocessor and microcontroller interfacing, energy iteration in design considerations, and connectivity technologies that are critical to health monitoring in real time. This study now takes a look at the memory hierarchy in computing and how it contributes toward the performance optimization of the system with respect to energy efficiency and cost. Through the study of the various functions carried out by Random-Access Memory (RAM), Read-Only Memory (ROM), and virtual memory, the paper emphasizes the other ways in which digital memory systems promote computational efficiency. These findings reinforce how IoT healthcare innovations and memory management enhance medical diagnostics and computing performance.
