Firmware development focuses on creating low-level code that directly interacts with hardware, while software development typically involves higher-level applications that run on operating systems.
C and C++ are crucial for firmware development, with assembly language being important for performance-critical and low-level hardware interaction tasks.
It's vital. Firmware developers must understand hardware architecture and operation to write effective code that controls and interacts with electronic components.
Yes, firmware updates can patch vulnerabilities, enhance security protocols, and protect devices from emerging threats.
Current trends include IoT integration, a focus on security, the incorporation of AI and machine learning, energy efficiency improvements, and enhanced cloud connectivity.
