Physical Devices
Physical devices refer to tangible hardware components such as smartphones, tablets, IoT sensors, embedded systems, and industrial machines that run software applications. They encompass a wide range of computing hardware from consumer electronics to specialized industrial equipment, often interacting with software through operating systems, drivers, and APIs. Developers work with physical devices to create applications that leverage hardware capabilities like sensors, connectivity, and processing power.
Developers should learn about physical devices when building applications for IoT, mobile, embedded systems, or hardware-software integration, as it enables direct interaction with hardware features such as GPS, cameras, or sensors. This is crucial for fields like robotics, smart home automation, industrial control systems, and mobile app development where software must interface with real-world hardware. Understanding physical devices helps optimize performance, ensure compatibility, and implement security measures for hardware-dependent applications.
