GPS and GSM modules are hardware components used in tracking devices to determine location and communicate data wirelessly.

• GPS module receives signals from satellites to determine location coordinates

• GSM module uses cellular network to transmit data to a remote server or device

• Both modules work together in tracking devices to provide real-time location updates

• Example: A GPS module like NEO-6M and a GSM module like SIM8

RTOS is designed for real-time applications with strict timing requirements, while normal OS is more general-purpose.

• RTOS is optimized for deterministic response times, ensuring tasks are completed within specific time constraints.

• Normal OS prioritizes multitasking and resource sharing, which may lead to less predictable response times.

• RTOS is commonly used in embedded systems, automotive control systems, and industria...read more
