Verified By Collegedunia
The Correct Option is A
Solution and Explanation
The Data Science workflow follows a logical progression from raw data to final communication.
1. Step-by-Step Logic:
• Data Collection (C): The foundation of any project. You must first acquire the raw data.
• Data Preprocessing (A): Cleaning, handling missing values, and preparing the data for the algorithm.
• Model Building (B): Selecting the algorithm and training it on the prepared data.
• Model Evaluation (E): Testing the model against metrics (accuracy, precision, etc.) to ensure it works.
• Data Visualization and Interpretation (D): Final step where insights are communicated through charts and reports. 2. Resulting Sequence: The only logical flow is C $\to$ A $\to$ B $\to$ E $\to$ D.

- Choose the correct answer from the options given below:
(A). RAID 3 requires only a single redundant disk.
(B) In RAID 4 scheme, two different parity calculations are carried out and stored in separate blocks on different disks.
(C) RAID 5 distributes the parity strips across all disks.
(D) In RAID 2, the number of redundant disks are proportional to the log of the number of data disks. - In case of DMA, after the completion of the transfer, the processor is required to be notified of the completion. This is done through.
- In a two-level memory hierarchy, the access time of the cache memory is 12 nsec and the access time of the main memory is 1.5 msec. The hit ratio is 0.98. What is the average access time of the two-level memory system?
- Match List I with List II.
List I List II A. Supervisor mode I. Entered when the processor encounters a software interrupt instruction B. Abort Mode II. Entered in response to memory fault C. Fast Interrupt Mode III. Entered whenever the processor receives an interrupt signal from a designated fast interrupt source D. Interrupt Mode IV. Entered whenever the processor receives an interrupt signal from any other source - Deallocation of stack of thread and register contexts will take place.
