• A. Compile time
• B. Frequency
• C. Deadlines
• D. Execution time

Explanation: A deadline is the time limit by which a real-time system must process a stimulus and produce a response.

• A. 50 ms
• B. 55 ms
• C. 70 ms
• D. 100 ms

Explanation: User authentication is the aspect responsible for requesting and validating a login name and password.

• A. Separation of concerns
• B. Writing aspects
• C. Finding code complexity

Explanation: Separation of concerns keeps different responsibilities independent, making software easier to understand, modify, and test.

• A. 1ms
• B. 10ms
• C. 100ms
• D. none of the mentioned

Explanation: The power monitor must react very quickly, so its average execution time is specified as less than 1 ms.

• A. High-speed data acquisition system
• B. Failure of a power supply in an embedded system
• C. Both High-speed data acquisition system AND Failure of a power supply in an embedded system
• D. None of the mentioned

Explanation: A high-speed data acquisition system can divide acquisition, processing, and storage into successive pipeline stages, allowing them to…

• A. software re-engineering
• B. artificial programming
• C. aspect-oriented programming
• D. all of the mentioned

Explanation: Aspect-oriented research has mainly developed aspect-oriented programming, which modularizes concerns that otherwise cross-cut multiple…

• A. aspect
• B. join point
• C. join point model
• D. weaving

Explanation: Weaving is the process of inserting an aspect's advice code at the selected join points in the base program.

• A. aspect
• B. join point
• C. join point model
• D. pointcut

Explanation: A join point is a specific event or location during program execution, such as a method call, where an aspect's advice may run.

• A. UI
• B. DBMS
• C. Application subsystem
• D. None of the mentioned

Explanation: The application subsystem contains the business logic that implements the functional requirements of the application.

• A. Local Presentation
• B. Distributed presentation
• C. Remote presentation
• D. All of the mentioned

Explanation: Remote presentation keeps the database and application logic on the server, while the client uses the received data to construct the user…

• A. File servers
• B. Database servers
• C. Client servers
• D. None of the mentioned

Explanation: A database server receives SQL statements from clients, executes them against stored data, and returns the results over the network.

• A. Distributed logic
• B. Distributed presentation
• C. Remote presentation
• D. All of the mentioned

Explanation: Distributed logic assigns presentation and data-entry processing to the client, rather than limiting it to display duties.

• A. obtain pertinent information about the desired method from the interface repository
• B. create a data structure with parameters to be passed to the object
• C. create a request for the object
• D. all of the mentioned

Explanation: CORBA dynamic invocation obtains the method description from the interface repository, packages the arguments into a request structure…
