Step by step
Solved in 2 steps
- Computer Science Write a code segment with a parent process having 3 child processes, wait for the last child process to finish before exitingA travel authorisation form is used in most companies to approve travel expenses for employees. Typically, an employee fills out a blank form and sends it to his or her manager for a signature. If the amount is (< R500), then the manager signs the form and routes it to accounts payable to be input into the accounting system. The system generates a check that is sent to the employee for the right amount, and after the check is cashed, the form is filed away with the cancelled check. If the check is not cashed within 90 days, the travel form expires. When the amount of the travel voucher is (> R500), then the manager signs the form and sends it to the chief financial officer, along with a paragraph explaining the purpose of the travel; the chief financial officer signs the form and passes it along to accounts payable. Of course, both the manager and the chief financial officer can reject the travel authorization form if they do not feel that the expenses are reasonable. In this…please write with proper explanation. Question half solution is here please write what is main disadvantages of this approach? Half solve questions: Mutual Exclusion: Mutex is an abbreviation for Mutual Exclusion. It is a programme object that prevents multiple users from accessing a shared resource at the same time. When a process accesses a shared variable, it is said to be in the critical section. When no two processes are present in the critical section at the same time, this is referred to as Mutual Exclusion or Mutex. while (true) { semaphore sem = S; while (S <= 0) do no operation { S = S-1; wait (S); } /*critical section*/ while (S > 0) { S = S+1; signal (S); } /*remainder section*/ }
- process( A, B ) begin Z <= (A or not(B)) and C; end process; In this example, what happens to Z if A or B change? If C changes, what will happen to Z?What is the difference between dynamic and static libraries? A. Dynamic libraries are linked when executable libraries are added to memory, and static libraries are inked alter the program is placed in the memory B. Dynamic libraries are much larger than static libraries because external programs are built in the executable file that is added to memory C. Static libraries are linked when executable libraries are added to memory, and dynamic libraries are linked after the program is placed in the memory D. Static libraries can be linked to any program at run time however, the program has to be loaded for the dynamic library code to be usedCourse Title: Object Oriented Analysis and Design Question : There is a utility company which provides waste management services to citizens. It has a CRM system, billing system, messaging system and mapping (GIS) system. When a customer is created in the CRM system, the billing, messaging, and GIS systems need a copy of customer data to perform follow-up tasks and automation. For instance—the billing system will create a billing account for the customer, the messaging system will send a welcome message with customer account details on preferred communication channel and the GIS system will update the customer’s address in the database for mapping purposes. After completion of one billing cycle the billing dept. sends a copy of the bill in a pdf format on the customer email address and the bill amount is directly debited from the customer’s bank account. Draw an appropriate Activity diagram . (Note): Forks and joins have the same notation: either a horizontal or vertical bar (the…
