Computer Science question

(a). Iteration and recursion are two very fundamental concepts underlying things we do in computing. (i). In your own words, compare and contrast the terms Iteration and Recursion in the context of solving problems in business, science or engineering; and explain the areas of use (in practice) of each of them. (ii). Using practical examples in business, science or engineering, explain reasons why people still use recursion to solve problems even-though iteration is more efficient. (b). In various fields of human endeavor, we use queues and stacks on daily basis. (i). In your own words, distinguish between queues and stacks in the context of computer-based information systems as against business operations; and draw a table of comparison to illustrate your answer. (ii). Provide two practical examples where we use queues and/or stacks in each of the following fields: (i). Business (ii). Education (iii). Manufacturing (iv). Computer Science

Question in Computer Science

To extend the battery lifetime, most contemporary devices have “sleep mode,” which reduces the duty cycle of the battery. Assume that there are the following three possible states of a device with the corresponding current drainage: sleep mode – 1 [mA], receive mode – 5 [mA], and transmit – 250 [mA]. Calculate the battery lifetime as a function of the battery duty cycle if the subscriber makes 1 call: (a) once a day, (b) every 6 hours, (c) every hour. Assume, that the battery capacity is 1[A*h] and that a call lasts 3[min].

With the advent of the modern civilization, rules were created for the citizens of various countries that helped bring down the chaos. Can we expect something on similar lines, i.e rules for AI machines as they seem to make a progressive leap in the coming decades?
