Answer:
from socket import *
hostname = input('Enter the host to be scanned: ')
ip_add = gethostbyname(hostname)
connections = [ ]
for i in range(133, 136):
s = socket(AF_INET, SOCK_STREAM)
conn = s.connect_ex((ip_add, i))
print(conn)
connections.append(conn)
if 0 in connections:
print ('Host is online')
s.close()
else:
print ('system is unreachable')
Explanation:
The python source code above scans for all the available range of ports in the provided hostname, if any port is available, the host is online else the program print the error message "system is unreachable.
Which input value causes the loop body to execute a 2nd time, thus outputting "In loop" again? { String s = "Go"; while ((!s.equals("q"))&& (!s.equals("")) System.out.println("In loop"); 5 - scnr.nextO;
a) "Quit"
b) "q" only
c) "Q only
d) Either "q" or "Q"
Answer:
a) "Quit"
c) "Q only
Explanation:
Given
String s = "Go";
while ((!s.equals("q"))&& (!s.equals(""))) {
System.out.println("In loop");
s = scnr.next();
}
Required
What input causes another execution
Analyzing the while condition
while ((!s.equals("q"))&& (!s.equals("")))
This can be split into:
!s.equals("q")) && (!s.equals(""))
Meaning
When s is not equal to "q" and when s is not an empty string
In other words,
the loop will be executed when user input is not "q" and user input is not empty.
So, from the list of given options: The loop both will be executed when:
a) Input is "Quit"
c) Input is Q only
Input of q will terminate the loop, hence b and d are incorrect

Answer: B C
Explanation:
Answer:B,C,D
Explanation:
Determine the number of character comparisons made by the brute-force algorithm in searching for the pattern GANDHI in the text
THERE_IS_MORE_TO_LIFE_THAN_INCREASING_ITS_SPEED
(Assume that the length of the text-it is 47 characters long- is known before the search starts).
Answer:
Total number of character comparison = 43
Explanation:
Using the Brute force algorithm
The string of n characters is known as text, and the string of m characters is known as the pattern.
From the given information:
The text (n)=THERE_IS_MORE_TO_LIFE_THAN_INCREASING_ITS_SPEED
The pattern (m) = GANDHI
The total no of characters that we have in the text = 47
The total number of characters in pattern = 6
For a brute force algorithm;
Since; the first character of the pattern does not exist in the text, then the number of trials made can be attempted can be expressed as = n – m + 1
= 47 – 6 + 1
= 47 – 5
= 42
Thus; the algorithm will attempt the trial 42 times.
Now, for loop in the algorithm to run 42 times, the G in the pattern will have to align against the for T in the text, and in the last case, it will be aligned against the last space.
On each attempted trial, the algorithm will make one unsuccessful comparison.
However, at the trial at which the G in the pattern Is aligned with the G in the text, there will be two successful comparisons.
Hence, we can calculate the total number of character comparison as follows:
Total number of character comparison = [tex]\mathbf{\bigg ( ( 42 - (no. \ of \ failed \ comparison) ) \times 1 + (1 \times ( Two \ successful \ comparisons) ) \bigg ) }[/tex]
Total number of character comparison = ( (( 42 – 1) × 1 ) + ( 1 × 2) )
Total number of character comparison = 41 + 2
Total number of character comparison = 43

True or false: Simultaneous multithreading (SMT) uses threads to improve resource utilization of a dynamically scheduled, out-of-order processor.
Answer:
True
Explanation:
Simultaneous multithreading or otherwise called, SMT that is a technique that us used for improving the total and overall efficiency of superscalar CPUs with hardware multithreading. Simultaneous Multithreading allows different types of independent threads, ability to execute and then eventually take optimum and much better use of the resources that is provided by modern processor architectures. Multithreading can not only allow multiple threads to be executed simultaneously in a single CPU core, it also allows multiple tasks some of which are different page tables, different I/O permissions, and others to be executed
One of the primary principles of the Rapid Application Development methodology is early prototyping of the _______ in the development cycle
Answer:
Software Applications
Explanation:
Rapid Application Development (RAD) also is an agile project management strategy used in the development of software. RAD is also referred to as Rapid Application Building (RAB).
Its greatest advantage is that it reduces the time taken to churn out a program and this is why a lot of developers are now adopting it.
This is made possible by reducing the amount of time and effort spent on planning and increasing the amount of energy spent on creating prototypes.
Other merits of this methodology are:
It reduces the risk associated with the project by ensuring that the program is first used as a prototype rather than the real deal. It ensures better quality. When users interact with the prototypes, they are able to provide very useful feedback that goes back into development to enhance the quality of the project.Cheers!

Using range(1,101), make two list, one containing all even numbers and other containing all odd numbers. How can I do this on Python
Answer:
even = []
odd = []
for i in range(1,101):
if i % 2 == 0:
even.append(i)
else:
odd.append(i)
Using range(1,101), the list of even and odd number can be done in python as follows;
odd_numbers = []
even_numbers = []
for i in range(1, 101):
if i%2 == 0:
even_numbers.append(i)
else:
odd_numbers.append(i)
print(even_numbers)
print(odd_numbers)
The variable odd_numbers is initialise with an empty list
The variable even_numbers is initialise with an empty list.
Then we loop through the range 1 to 101 as required.
If the looped numbers is divided by 2 without a remainder then the number is appended to the empty list even_numbers.
Else if it has a remainder, the looped number are appended to the empty list, odd_numbers.
Then we print the even_numbers and odd_numbers.
