Question Answered step-by-step A child’s toy is battery operated and has four large illuminated… A child’s toy is battery operated and has four large illuminated push buttons, a number of smaller buttons and a loudspeaker that is used to play tunes. Production will be 50 000 units per month for at least six months. (a) Give a block diagram of the product, showing the principal partition decisions. Describe the function of each block, explaining why it exists and how it should be made. [6 marks] (b) You may (or may not) have used a microprocessor – explain why your design strategy is a good idea and discuss the alternative approach. [6 marks] (c) How would you test the product concept before production? [4 marks] (d) How would you test the product in production before shipping? [4 marks]  In a large-scale distributed system, what advantages might be gained by using role-based access control (RBAC)? [2 marks] A server which is an object manager implements RBAC by issuing principals with persistent capabilities which include the fields “role” and “object-name”. Describe how a signature field in the capability can be used to ensure its integrity. Define the protection the signature does and does not enforce. [6 marks] How can such a persistent capability be made principal-specific? To what extent does this improve protection? [4 marks] Discuss the desirability or otherwise of the persistence of capabilities and the use of persistent principal names. [4 marks] Discuss revocation for the capability schemes suggested above. [4 marksDescribe how Floyd-Hoare logic can be used to define the semantics of programming languages (axiomatic semantics). Give advantages and disadvantages of this approach. [5 marks] Describe the general idea of how program verification may be mechanised using verification conditions. Discuss what can be done completely automatically and what requires manual assistance. [5 marks] Describe the difference between deep and shallow semantic embeddings of one language in another and compare and contrast the benefits of each. What is the point of embedding Floyd-Hoare logic in higher order logic? [5 marks] Discuss possible commercial uses of formal software verification. How would you justify its use? [5 marks] 3 Digital Communication II What information does a host require to transmit an IP datagram to a given destination IP address? [3 marks] Describe how the host determines this information. How does this change in the presence of subnets? [3 marks] Routing protocols can be classified as either link-state or vector distance. (a) Briefly describe the operation of each of these schemes. [4 marks] (b) In which case does the overall state converge more rapidly after a change? Justify your answer. [2 marks] (c) Which scheme is more scalable? Justify your answer. [2 marks] Sketch a design for a transport protocol providing reliable data transmission over IP multicast. What are the main issues here? Which changes within the network could lead to a more efficient implementation?Image transcription text4.

Question Answered step-by-step The following is all the information given. As a floor supervisor:... The following is all the information given.  As a floor supervisor:• Create the distribution of personnel (BSN and LPN) for shift 7-3 and place the Rs at theirdiscretion (if someone is missing they have to double shift).• Add numbers to the rooms to identify them• Distribute bed baths equitably to LPN staff. At a Hospital in San Juan, in the Telemetry area there is a staff of 5 graduate nurses, 3 practical nurses, 1 supervisor.  It has 7 isolation rooms (only 1 patient) and 25 regular rooms (capacity double). For a total of 32 rooms and 57 patients. All rooms are occupied. Of the 7 rooms that you have as supervisor of the floor, you have 5 occupied with intubated patients, category V. In addition to bedridden patients who are bathing in bed, you have 11 additional bed baths.Staff peculiarities.BSN Nurse 1- Takes 4 shifts in a row. This would be his last turn and he has R.
