How does Clean room software engineering Differs from the conventional and object-oriented views ?

How does Clean room software engineering Differs from the conventional and object-oriented views ?

A. It makes explicit use of statistical quality control
B. It verifies design specification using a mathematically based proof of correctness
C. It relies heavily on statistical use testing to uncover high-impact errors
D. All of the mentioned

The times by which stimuli must be processed and some response produced by the system is known as____________________?

The times by which stimuli must be processed and some response produced by the system is known as____________________?

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

Explanation: If the system does not meet a deadline then, it results in a system failure; in a soft real-time system, it results in degraded system service .

Which of the following is represented as an aspect that requests a login name and password ?

Which of the following is represented as an aspect that requests a login name and password ?

A. Class
B. Object
C. User authentication
D. All of the mentioned

Explanation: User authentication may be represented as an aspect that requests a login name and password. This can be automatically woven into the program wherever authentication is required.

Which of the following is a key principle of software design and implementation ?

Which of the following is a key principle of software design and implementation ?

A. Separation of concerns
B. Writing aspects
C. Finding code complexity
D. None of the mentioned

Explanation: The separation of concerns is a key principle of software design and implementation. It means that you should organize your software so that each element in the program (class, method, procedure, etc.) does one thing and one thing only.

An example of a system that may use a process pipeline is a _________________________?

An example of a system that may use a process pipeline is a _________________________?

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: Data acquisition systems collect data from sensors for subsequent processing and analysis. These systems are used in situations where the sensors are collecting a lot of data from the system’s environment and it isn’t possible or necessary to process that data in real time.
