Answer:
The single greatest physical threat to information systems is:
Sabotage
Explanation:
Sabotage describes the efforts of internal persons to ensure that a system does not operate as intended or is destroyed. Among the threats to information systems, this is the greatest. The problem with sabotage is that the operators are internal, they know the system very well. They understand the weak points and the strengths of the system. They are internal terrorists to any information system. These internal saboteurs are capable of using any means to achieve their purpose. Therefore, it is necessary to scrutinize employees from time to time to discover internal risks.

Explanation:
In this scenario, your network administrator finds a virus in the network software. Fortunately, she was able to eliminate it before it resulted in a denial-of-service attack, which would have prevented legitimate users of the networked database from gaining access to the records needed. It turns out that the network software did not have adequate security protections in place. The fact that this virus was successfully inserted into the network software points to a vulnerability of the network software.
In Cybersecurity, vulnerability can be defined as any weakness, flaw or defect found in a software application or network and are exploitable by an attacker or hacker to gain an unauthorized access or privileges to sensitive data in a computer system.
This ultimately implies that, vulnerability in a network avail attackers or any threat agent the opportunity to leverage on the flaws, errors, weaknesses or defects found in order to compromise the security of the network.
Some of the ways to prevent vulnerability in a network are;
1. Ensure you use a very strong password with complexity through the use of alphanumerics.
2. You should use a two-way authentication service.
3. You should use encrypting software applications or services.

Fix the error so that the code works correctly
input (“Enter a number: “)
print (num * 8)
How do I fix the error?
Answer:
num = int(input("Enter a number: "))
print(num * 8)
Explanation:
I highlighted the parts that are added
Since you are getting an input from the user, you need to set the result to a variable. In this case, it is num.
Since it is a number, you need to specify the its type. In this case, it may be int.
Also, the quotation marks must be written as seen.
The corrected program which ensures that the program runs correctly is written thus :
num = int(input("Enter a number: ")
#user supplied input should be assigned to the varibale num
print(num * 8)
#multiplies num by 8 and displays the output.
The num variable in the second line isn't attached to any value, therefore, it will throw an error. The user input value should be attached to the variable, 'num' The second line of code multiplies num by 8 and displays the product.Therefore, if the the user input is 3 ; the final result displayed will be : (3 × 8) = 24.

Answer:
b. AES
Explanation:
AES is an acronym for Advanced Encryption Standard and it is a cryptographic or symmetric block cipher that is based on a substitution-permutation network (SPN) used for the encryption of sensitive data over the internet or web. AES uses a key length of 128, 192 or 256 bits and a block length of 128 bits to encrypt data on web applications.
It is an encryption standard of the government of the United States of America and is supported by the National Institute of Standards and Technology (NIST).
Hence, AES is used to encrypt web application data and it uses an algorithm developed by Vincent Rijmen and Joan Daemen, known as the Rijndael algorithm.

print() essentially just calls up the native print dialog for a given window.
But as you're are thinking, it will work on any window or (i)frame.
thus if you write content to a frame, you can then call this to print it.
window.frameName.print();
note the only drawback (and its a big one), is that this calls up the print dialog... not the print preview window... thus the user doesn't really get a chance to see what they are printing and/or scale it to fit their printer/paper.
I personally wish that all browsers would implement the following to handle the above issue.
window.printPreview();

Write a MATLAB function named average_of_scores_with_drops The function will have two inputs and two return values. The first input will be a list of scores. The second input will be a postive integer representing the number of scores to drop. It will not be larger than the length of the list. Your function should determine the average of the scores after dropping the specified number of lowest scores. The first return value must be a real number equal to the average score. The second return value must be the number of items that were averaged. Notes: Example Test Case: SCORES
Answer:
-%Define the function.
function [avg, ele_left] = average_of_scores_with_drops(input_list, drop_element)
%Sort the list.
input_list = sort(input_list);
%Compute the length of the list.
len_list = length(input_list);
%Declare and initialize the variable.
sum = 0;
%Increase the element to be drop by 1.
i = drop_element + 1;
%begin the for loop.
for k = i : length(input_list)
%Add the elements.
sum = sum + input_list(k);
%End of the for loop.
end
%Compute the elements left after dropping the dropped element.
ele_left = length(input_list) - drop_element;
%Compute the average of the elements left.
avg = sum/ele_left;
%End of the function defined.
end
%Run the following code in the command prompt.
%Call the function and return the average
%score and the number of elements
%whose average is computed.
[average_score , number_of_items] = average_of_scores_with_drops([8 6 1 2 3 5 10], 2)

Answer:
d. all of the above are true
Explanation:
Connectionless Packet Switching is a term that is used in computer networking operations to describe the breaking of information exchange path into a various packet of small sizes acquired and refined over network switches and routers, which is then transferred from one subsequent node to the other. It is sometimes referred to as Datagram Networks
However, during this operation, Connectionless Packet Switching must satisfy the following amongst others:
1. each datagram must comprise both source and destination addresses
2. without a connection, datagrams may not come in sequential order at the destination
3. establishment of a connection between communicating points is not needed prior to exchanging datagrams, thus reducing overhead communications
Therefore, considering the available options, the correct answer is option D

Write code that determines the number of full days represented by the number of hours stored in the variable hours and stores that value in the variable full_days. For example, the number of full days in 50 hours is 2. Ignore any leftover hours that don't contribute to a full day. Assume the value of hours has already been initialized. Solve It!
Answer:
hours = 50
full_days = int(hours / 24)
print("The number of full days in " + str(hours) + " hours is " + str(full_days))
Explanation:
Initialize the hours
Since there are 24 hours in a full day, divide the hours by 24. Note that you need to typecast it to the int, because the result is a decimal value by default

Orthogonality or simplicity, available control structures, data types, and data structures, syntactic design, support for abstraction, expressiveness, type equivalence, strong versus weak type checking, exception handling, and limited aliasing are among the characteristics of a programming language.
Clarity, simplicity, and unity offer a way to express algorithms as well as a framework for thinking about them. Every possible feature combination has value thanks to orthogonality. Surprisingly, it may frequently be reduced to three basic programming constructs known as loops, selects, and sequences.
