Question 1

time taken by header of a message between two directly connected nodes is called as-----------------
A)startup time
B)per hop time
C)per word transfer time
D)packaging time

Accepted Answer

The time taken by the header of a message between two directly connected nodes is referred to as "per hop time." This term is used to describe the duration required for a data packet's header to travel from one node to another in a network, emphasizing the per-segment or per-link basis of the measurement.

Question 2

the number of switch requirement for a network with n input and n output is ------------------
A)n
B)n2
C)n3
D)n4

Accepted Answer

The number of switches required for a network with n inputs and n outputs, assuming a non-blocking network architecture like a crossbar switch, is n^2. This is because each input can potentially be connected to any of the outputs, requiring a switch at each possible intersection, leading to a total of n*n or n^2 switches.

Question 3

which of the following is not static network
A)bus
B)ring
C)mesh
D)crossbar switch

Accepted Answer

A crossbar switch is a dynamic network that allows for flexible connections between inputs and outputs, unlike static networks like bus, ring, and mesh which have fixed connections.

Question 4

In super-scalar processors, ________ mode of execution is used.
A)in-order
B)post order
C)out of order
D)none of the mentioned

Accepted Answer

Super-scalar processors can execute instructions out of order to improve performance, utilizing multiple execution units to process several instructions simultaneously.
