Question 51
Warnier Diagram enables the analyst to represent:
Step-by-Step Solution
Detailed Explanation:
Warnier-Orr diagrams use brackets to represent hierarchical relationships among data and processes (Information Hierarchy).

Given X: 0, 10, 16 and Y: 6, 16, 28.
The interpolated value at $X=4 using piecewise linear interpolation$ is:
Detailed Explanation:
$X = 4 lies$ in the interval [0, 10] with endpoints (0, 6) and (10, 16).
$Linear interpolation equation: Y(X) = Y0 + ((Y1 - Y0) / (X1 - X0)) \times (X - X0).$
$Y(4) = 6 + ((16 - 6) / (10 - 0)) \times (4 - 0) = 6 + (1 \times 4) = 10.$
In functional dependency Armstrong inference rules refers to:
Detailed Explanation:
Armstrong's three fundamental axioms for functional dependencies are:
Reflexivity: If Y ⊆ X, then X → Y.
Augmentation: If X → Y, then XZ → YZ for any Z.
Transitivity: If X → Y and Y → Z, then X → Z.
Option B lists all three axioms. Decomposition is a derived rule, not one of the three basic axioms.
Number of chips (128 x 8 RAM) needed to provide a memory capacity of 2048 bytes:
Detailed Explanation:
Single chip capacity = 128 bytes.
Target memory capacity = 2048 bytes.
Number of chips required = 2048 / 128 = 16 chips.
There are three processes in the ready queue. When the currently running process requests for I/O how many process switches take place?
Detailed Explanation:
When the running process yields CPU for I/O, CPU scheduler performs exactly 1 context switch to dispatch the next ready process from the queue.
