Embedded Systems Glossary

RTOS (Real-Time Operating System)

A specialized OS that guarantees timely task execution. RTOS is essential in mission-critical systems like aerospace and medical devices.

Microcontroller

A single chip containing CPU, memory, and peripherals. It controls embedded devices like washing machines, drones, and sensors.

FPGA (Field Programmable Gate Array)

A reconfigurable silicon chip used in embedded development. Designers can optimize logic circuits without manufacturing new hardware.

IoT (Internet of Things)

A system of smart devices that communicate over the internet. Embedded systems act as the brains behind smart homes, cities, and industry automation.

Firmware

Permanent software programmed into ROM that controls hardware functions. Firmware is updated less often but is crucial to system stability.

Embedded Security

Techniques and features that protect embedded systems from threats. Includes secure boot, encryption, and hardware firewalls for IoT and critical devices.
