21.       Which one of the following media is multidrop?
(A) Shielded Twisted pair cable
(B) Unshielded Twisted pair cable
(C) Thick Coaxial cable
(D) Fiber Optic cable
22.       What is the baud rate of the standard 10 Mbps Ethernet?
(A) 10 megabaud
(B) 20 megabaud
(C) 30 megabaud
(D) 40 megabaud
Explanation:
The Ethernet uses Manchester encoding, which means it has two signal periods per bit sent. The data rate of the standard Ethernet is 100-Mbps, so the baud rate is 200 Mbaud.
23.       At any iteration of simplex method, if Δj (Zj – Cj) corresponding to any non-basic variable Xj is obtained as zero, the solution under the test is
(A) Degenerate solution
(B) Unbounded solution
(C) Alternative solution
(D) Optimal solution
24.       A basic feasible solution to a m-origin, n-destination transportation problem is said to be ................... if the number of positive allocations are less than m + n – 1.
(A) degenerate
(B) non-degenerate
(C) unbounded
(D) unbalanced
25.       The total transportation cost in an initial basic feasible solution to the following transportation problem using Vogel’s Approximation method is
(A) 76
(B) 80
(C) 90
(D) 96
26.       An actor in an animation is a small program invoked ............... per frame to determine the characteristics of some object in the animation.
(A) once
(B) twice
(C) 30 times
(D) 60 times
27.       Bresenham line drawing algorithm is attractive because it uses
(A) Real arithmetic only
(B) Integer arithmetic only
(C) Floating point arithmetic
(D) Real and integer arithmetic

(A) Crucial fusion frequency
(B) Current frequency fusion
(C) Critical fusion frequency
(D) Critically diffused frequency
29.       In homogenous coordinate system (x, y, z) the points with z = 0 are called
(A) Cartesian points
(B) Parallel points
(C) Origin point
(D) Point at infinity
