- Assignment/Lab 9 In this lab, your task is to develop a simple address book tool. The tool maintains contact information of people. For each person, the tool maintains name and date of birth. Contact information consists of physical address and phone number. For physical addresses, the system must be able to maintain current and previous addresses. Current/active address information should have starting date and no end date, previous addresses must have a starting date and an ending date. A person cannot have multiple active physical address. For phone number, the system must maintain active phone numbers only, no previous phone numbers. For implementation, use MySQL database system. MySQL is open source and is available for Linux as well as Windows. For software application, use Python. The tool/application must support the following functionality: 1- Search current contact information by last name, the user enters last name, the system must locate active physical address and phone…Draw a component diagram would illustrate the following components and their relationships: (Please draw with computer.) HoneynetCentralServer Dependencies: Honeypot, LogProcessor Honeypot Dependencies: LogEntry LogEntry LogProcessor Dependencies: MongoDBAtlasDatabase, ExternalAPI (optional) MongoDBAtlasDatabase Dependencies: StoredLogEntry StoredLogEntry ManagementTool Dependencies: HoneynetCentralServer or LogProcessor (depending on where data fetching occurs), ExternalAPI (optional) ExternalAPI To create the component diagram, you would represent each component as a rectangle with its name inside. Then, draw dependency arrows between the components to show their relationships, as indicated in the list above. For example, you would draw an arrow from HoneynetCentralServer to Honeypot and another arrow from HoneynetCentralServer to LogProcessor to indicate that the HoneynetCentralServer depends on these two components. Similarly, draw arrows between other components…m6 C++ Question: Make an execution chart like the example below for the code provided. Example chart: An execution chart is a text version of the hierarchy. Indentation is used to indicate thesublevels or calls inside a call. It also contains the data exchange between the components asdesignated in the hierarchy chart.

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*/ }
- From a programmer point of view, make an argument that supports the use of deep access rather than shallow access; try to avoid an argument that revolves around performance.If you are a developer, as opposed to a user, it is in your best interest to utilise deep access rather than shallow access. This is because deep access provides more security. Users should only have access to limited resources at most.50. Match the following.i) Mutual exclusion a) A process may hold allocated resources while waiting assignment.ii) Hold and wait b) No resource can be forcibly removed from a process holding it.iii) No preemption c) Only one process may use a resource at a time. a. i-a, ii-b, iii-c b. i-a, ii-c, iii-b c. i-b, ii-c, iii-a d. i-c, ii-a, iii-b

Furthermore, at any time, a process should be able to access only those resources that it currently requires to complete its task. This is commonly referred to as the need-to-know principle, or domain of protection. Discuss this “domain” and its structure, including the following: Whether the relationship between a process and a domain is static or dynamic Domain switching How domain switching happens in the following cases: Each user is a domain Each process is a domain Each procedure is a domain
