Goal: Practice of software modeling using UML Consider the following use case specification for a use case called "Search Student" Search student Brief description: The actor receives results of students Actors: Participant Preconditions: The actor is a registered student Basic flow of events: 1. The actor logs into the system 2. The system authenticates the actor and starts a session 3. The actor chooses to search for student 4. The actor is guided by the system to fill the required criteria's to search for student 5. The actor receives results for student 6. The actor leaves the system Extensions: 1a. The system fails to authenticate the actor. • The system informs the actor and doesn't allow the actor to proceed 3a. The system fails to search • The system informs the actor Post-conditions: The system outputs results for the search of student Special requirements: Actor is connected to Internet and uses a Java enabled Mobile phone 1. Draw a class diagram for this use case (5 marks) 2. Draw a sequence diagram for this use case (5 marks)
Answers
The main answer is to provide a class diagram and a sequence diagram for the "Search Student" use case.
What diagrams are needed for the "Search Student" use case?To effectively model the "Search Student" use case, two diagrams are required: a class diagram and a sequence diagram.
The class diagram represents the static structure of the system, showcasing the classes involved and their relationships. In this case, the class diagram would include classes such as "Actor," "System," and "Student." Associations, attributes, and methods can also be depicted to capture the essential elements and behaviors.
On the other hand, the sequence diagram illustrates the dynamic interactions between objects during the execution of the use case. It shows the sequence of messages exchanged between the actor and the system, highlighting the steps outlined in the use case specification.
Each step, such as logging in, authentication, searching, and receiving results, is represented by lifelines and messages.
These diagrams provide visual representations that aid in understanding the structure and behavior of the system during the "Search Student" use case. They facilitate communication among stakeholders, help identify potential issues, and serve as a foundation for implementing the software.

Which increases the rate of soil formation?
Answers
Answer: Increased temperature increases the rate of chemical reactions, which also increases soil formation. In warmer regions, plants and bacteria grow faster, which helps to weather material and produce soils. In tropical regions, where temperature and precipitation are consistently high, thick soils form.
Explanation: Hope this works
They are created from rocks (the parent material) by weathering and erosive forces of nature. Parent material is broken down by a variety of factors, including water, wind, gravity, temperature change, chemical reactions, living things, and pressure variations.
What are the factor involving in the formation of soil?Parent materials' rate of weathering and, consequently, soil characteristics like mineral composition and organic matter concentration are influenced by temperature and precipitation.
Faster plant and bacterial growth in warmer climates aids in the weathering of materials and the formation of soils. Thick soils develop in tropical areas where the temperature and precipitation are both constantly high.
Therefore, The rate of chemical reactions is accelerated by rising temperature, which also accelerates soil formation.

d. 6to4
Answers
Out of the four popular tunneling standards that enable you to link your IPv6 client to an IPv6 router over an IPv4 network, Teredo is the one built into Microsoft Windows. Option A.
What is Teredo?Teredo is a tunneling protocol that provides IPv6 connectivity by encapsulating IPv6 packets inside IPv4 packets. It was created to help transition to IPv6 when there is no native support for it.
It is designed to work with network address translation (NAT), which is commonly found in home and small office networks, to enable IPv6 connectivity.
Teredo is enabled by default on Windows Vista and later versions of the operating system and uses UDP port 3544 for communication. It can be disabled or enabled by utilizing the `netsh interface teredo set to state` command in the Command Prompt.
Hence, the right answer is option A. Teredo.

An input can come from a file or the command line. Reading the input and passing it to the program as necessary is achievable with C programming's built-in functions. The term “output” describes how data is shown, whether it's on a screen, a printer, or in a file.
What are the different output of c++?To accept input and show output in C++, input and output (I/O) operators are needed. The insertion or put to operator () is the operator used to display the output, whereas the extraction or get from operator (>>) is used to take the input.
