MS-DOS managed hardware device contention (see terminate-and-stay-resident program) by making each device file exclusive open. An application attempting to access a device already in use would discover itself unable to open the device file node. A variety of device driver semantics are implemented in Unix and Linux concerning concurrent access. [4]
Depending on the device type, different kernels can be selected; for instance, like OpenHarmony base itself but with a single kernel, lightweight systems are chosen for low-power devices like watches and IoT devices to execute lightweight HarmonyOS apps, whereas large-memory devices like mobile phones, tablets, and PCs utilize standard system.
Android 4.4 introduced the Storage Access Framework (SAF), a set of APIs for accessing files on the device's filesystem. [131] As of Android 11, Android has required apps to conform to a data privacy policy known as scoped storage , under which apps may only automatically have access to certain directories (such as those for pictures, music ...
CoAP is designed for use between devices on the same constrained network (e.g., low-power, lossy networks), between devices and general nodes on the Internet, and between devices on different constrained networks both joined by an internet. CoAP is also being used via other mechanisms, such as SMS on mobile communication networks.
