Answer:
when user wants duplicate copy of the object
Explanation:
Encapsulation are one of the key foundations of object-oriented programming (OOP). It involves the bundling of data or information with the methods and various techniques which operate on that data.
It can be used in hiding the true values or state of a structured data object that is in a class, preventing unauthorized parties' direct access to them.
The circumstances that can be allowed in returning a reference to the existing Engine is when user wants duplicate copy of the object.
I would want to see the word compatible in the specs
Answer:
Redundant paths can be available without causing logical Layer 2 loops.
Explanation:
- Spanning Tree Protocol is used to allow redundancy in the Layer 2 switched networks without creating cycles/circles also called loops.
- These loops are called physical loops.
- When two parts of the switched network are connected via two or more Layer 2 switches this result in a loop.
- This affects the performance of the network as the result of broadcast packets flooding.
- STP puts one port of the switch to forward mode and the rest of the ports within the same part of the network to the blocking mode to avoid broadcast packet flooding. STP puts all the ports that are allowing redundant paths to block mode and the one port that is left after this is placed in forward mode.
- Spanning Tree Algorithm is used by STP to determine the optimal path of switch to the network.
- Bridge Protocol Data Units are used to share the information about the optimal path determined by the spanning tree algorithm with other switches.
- This information helps STP to eliminate the redundant paths.
- So this is how STP tracks all the links in the switched network and eliminates redundant loops by allowing only one active path to the destination while blocking all other paths.
Answer: False
Explanation:Decision tree is the tree like structured flowchart which is used for the evaluation of the possible outcomes or result of the particular problem. It usually has two or more branches as the the result node . Decision tree are applicable to many problems for solving it. So, decision trees is not only applicable on certainty problems but also on other problems as well. Therefore the given statement is false.
The program is an illustration of loops and conditional statements
<h3>
Loops</h3>
Loops are used to perform repetitive operations.
<h3>
Conditional statement</h3>
Conditional statements are used to make decisions
<h3>The python program</h3>
The program in Python, where comments are used to explain each line is as follows.
#The following is repeated 5 times; i.e. the rows
for i in range(5):
#The following is repeated 5 times; i.e. the columns
for j in range(5):
#For rows 2 and 5
if i == 1 or i== 3:
#For columns 1 and 5
if j == 0 or j == 4:
#This prints *
print('*',end='')
#For other columns
else:
#This prints an empty space
print('',end=' ')
#For other rows
else:
#This prints *
print('*',end='')
#This prints a new line
print()
