Question 24 (4 points) Indicate whether each of the following are true for iOS only, Android only, or both iOS and Android. Architecture uses software stacks Based on an existing kernel (Linux or macOS) Uses a virtual machine Applications developed in Objective-C 1. iOS only Open source 2. Android only 3. Both iOS and Android Applications developed in Java Provide frameworks for developers Executes code natively Closed source Question 25 (1 point) Java programs running on Android systems do not use the standard Java API and virtual machine. Google developed a separate API and virtual machine for mobile devices.

True False Question 32 (1 point) A statically-linked library is only linked and loaded if it is conditionally required during program runtime. True False Question 33 (1 point) Applications that are designed to work on one operating system will also work on another operating system as long as they provide the same APIs. True False Question 34 (1 point) A microkernel is a kernel containing many components that are optimized to reduce resident memory size that is compressed before loading in order to reduce its resident memory size that is compiled to produce the smallest size possible when stored to disk that is stripped of all nonessential components Question 35 (1 point) allow operating system services to be loaded dynamically.
