Answer:
(a) yes, this protocol allows only serializable schedules for transactions as due to this the system maintains it's consistency. As in this protocol a unique transaction id is being assigned and with the help of that transaction id the system would be able to identify the process which has taken place in what particular order. For example, in case of bank transfers
balance = 1000 transaction id 100
write ADD 200 transaction id 101
write SUB 1100 transaction id 102
write ADD 900 transaction id 103
in here with the help of transaction id we can check which operation has happened in which order, if not then some operation will not happen like 102 immediately after 100 and skipping 101
(b) the modified version of this protocol would be to also consider the time of transaction and take this factor in the consideration
Answer:
Recursive solutions can be less efficient than their iterative counterparts
Explanation:
Recursion can be defined or described as a method of solving a problem where the solution depends on solutions to smaller instances of the same problem.
It entails using iteration to ensure that smaller parts of a solution are satisfied towards solving thw overall problem.
Ita major disadvantage seems to be that it seem to be less efficient than their iterative counterparts. This is as a result of concentrating on trying to solve a smaller instances.
Answer:
D. To ensure that the software adheres to technical standards
Explanation:
The responsibility of the software architect is to ensure that all parts of the software system are able to meet the requirements set forth by the project or specifications, in this case, the technical standards. This is an important piece of the software system because without it, the software system may not perform the necessary functions that it was written to do.
