B. UML
by using UML one can draw relationships between classes (types) & other
components of the program, so you have a visual view of the code of your program.
Answer:
Slide transition.
Explanation:
PowerPoint application can be defined as a software application or program designed and developed by Microsoft, to avail users the ability to create various slides containing textual and multimedia informations that can be used during a presentation.
Some of the features available on Microsoft PowerPoint are narrations, transition effects, custom slideshows, animation effects, formatting options etc.
Basically, the views that are available on the Microsoft PowerPoint application includes;
1. Slide Sorter.
2. Notes Page.
3. Reading Pane.
4. Presenter view.
In this scenario, Ryan has made a presentation of ten slides, which he wants to display in sequence after a specific time interval.
Using slide transition in the presentation software, Ryan can make the slides appear, one after the other, after a specific time interval.
Slide transition is an inbuilt feature of a presentation software that automatically changes the slides at regular intervals.

Answer:
Explanation:
To maintain data consistency and integrity in a large multi-user system, transactions are completed concurrently with the aid of concurrency management techniques.
The following are some of the benefits of concurrent transaction processing and execution versus serial transaction processing and/or execution:
Improved Resource Usage:
A transaction frequently combines both CPU and Input/output activities, resulting in better resource usage. Computers have the ability to run disks and CPUs in parallel. As a result, transactions can also be executed in parallel, with one employing the usage of the CPU and the other using the disk. As a result, resources are better used than in serial transaction processing and execution.
Improved throughput:
Running transactions in parallel has an immediate impact of increasing throughput since a greater number of transactions can be completed in the same period of time.
Lower/shorter waiting time:
Reduced wait time: When transactions are processed sequentially and serially, a short transaction is forced to wait for a longer transaction. Because transactions usually affect distinct portions of the database. As such, it's best if they happen at the same time i.e it is run concurrently.
The characteristics listed above are critical to a system's performance.
Thus, It is obvious that the benefits of concurrency exceed the extra programming work necessary to execute transactions concurrently. As a result, database systems must handle concurrent transactions despite the additional work necessary since it is worthwhile.
