How is the proliferation of mobile devices that are locally powerful, use apps instead of full-fledged applications, and rely on wireless network connectivity changing system architecture design considerations?
What will be an ideal response?
The move from centralized computing (e.g., mainframes) to personal computers changed system design. The current movement of computing “to the edge,” powered by mobile devices and wireless networks, is again changing system design.
The architectures are more network-centric. The apps that provide functionality are often under the control of the end-user, not the IT administrator, due to the BYOD nature of this system architecture. Security concerns may shift to protecting critical infrastructure from infection from the mobile devices, rather than the users’ equipment being infected or compromised by a central source.

Analyze the following fragment:
double sum = 0; double d = 0; while (d != 10.0) { d += 0.1; sum += sum + d; } a. The program does not compile because sum and d are declared double, but assigned with integer value 0. b. The program never stops because d is always 0.1 inside the loop. c. The program may not stop because of the phenomenon referred to as numerical inaccuracy for operating with floating-point numbers. d. After the loop, sum is 0 + 0.1 + 0.2 + 0.3 + ... + 1.9
