Bharath has made a table of content for his document in Open Office, in which he wants to make few changes, but he is unable to make the changes. Give reason. Explain how he can make the necessary changes
Answer:
H cannot update it because it is probably protected.
If you cannot click in the table of contents, it is probably because it is protected. To disable this protection, choose Tools > Options > OpenOffice.org Writer > Formatting Aids, and then select Enable in the Cursor in protected areas section. If you wish to edit the table of contents without enabling the cursor, you can access it from the Navigator.
Explanation:
. To update a table of contents when changes are made to the document:
Right-click anywhere in the TOC.
From the pop-up menu, choose Update Index/Table. Writer updates the table of contents to reflect the changes in the document.
You can also update the index from the Navigator by right-clicking on Indexes > Table of Contents1 and choosing Index > Update from the pop-up menu.
How can technology efforts be reconciled to improve hazard/disaster preparedness, response, and mitigation to insure systems sustainability, data integrity, and supply chain protection?
Answer:
Prediction
With regard to preparedness for hazard/disaster, technology such as AI are being explored to see how they can help to predict natural disaster.
If there is a breakthrough in this space, it will drastically reduce the negative impact of natural disasters such as floods and earthquakes as people will become ready to respond to them and mitigate their effects where possible.
In agriculture, there are factors which come together to bring about flooding. Flooding is one of the major disasters which cripples entire value chains. With a potential threat anticipated or predicted by AI, businesses can invest in technologies that can help protect the farms, farmland and other resources critical to such a supply chain.
AI-powered technologies that provide prediction services often combine this advanced computing prowess with the ability to process big data.
Technology can reach places that are unreachable by humans
AI-powered robots will soon become the norm.
Presently there are self-learning and self instructing robots powered by Artificial Intelligence that have applications in warfare, manufacturing, deepsea diving and intelligence gathering, and transportation. It is not out of place to predict that in the next decade, scientists would have perfected rescue robots that can go into very unstable terrain that have been damaged by flood or earthquake and attempt a rescue of lives and property at a scale that has never been possible before.
Connectivity
Connectivity helps people access to aid, resources that are critical for survival, transmission and receipt of life--saving information etc. CISCO has successfully used its technology called TacOps (short for Tactical Operations) successfully 45 times on over 5 continents.

An organization is planning to implement a VPN. They want to ensure that after a VPN client connects to the VPN server, all traffic from the VPN client is encrypted. Which of the following would BEST meet this goal?a. Split tunnelb. Full tunnelc. IPsec using Tunnel moded. IPsec using Transport mode
Answer:
B. Full tunnel.
Explanation:
In this scenario, an organization is planning to implement a virtual private network (VPN). They want to ensure that after a VPN client connects to the VPN server, all traffic from the VPN client is encrypted. The best method to meet this goal is to use a full tunnel.
A full tunnel is a type of virtual private network that routes and encrypts all traffics or request on a particular network. It is a bidirectional form of encrypting all traffics in a network.
On the other hand, a split tunnel is a type of virtual private network that only encrypts traffic from the internet to the VPN client.
Hence, the full tunnel method is the most secured type of virtual private network.

A computer uses a programmable clock in square-wav e mode. If a 500 MHz crystal is used, what should be the value of the holding register to achieve a clock resolution of (a) a millisecond (a clock tick once every millisecond)
Answer:
500,000
Explanation:
A computer uses a programmable clock in square-wave mode. If a 500 MHz crystal is used, what should be the value of the holding register to achieve a clock resolution of (a) a millisecond (a clock tick once every millisecond)
1 millisecond = 1 million second = 1,000,000
For a 500 MHz crystal, Counter decrement = 2
Therefore value of the holding register to a clock resolution of 1,000,000 seconds :
1,000,000/2 = 500,000

what level of security access should a computer user have to do their job?
Answer:
A computer user should only have as much access as required to do their job.
Explanation:
A computer user should not be able to access resources outside of their job requirement, as this poses a potential attack vector for an insider threat. By limiting the scope of resources to just what is needed for the user's specific job, the threat to the system or company can be mitigated with additional access control features for the computer user. Never allow permission higher than what are needed to accomplish the task.

Explain how Deep Packet Inspection works (DPI). How is this technology beneficial to Perimeter Security? Lastly, describe a scenario where the use of DPI may be considered a privacy concern.
Answer:
Answered below
Explanation:
Deep packet inspection is a kind of data processing that thoroughly inspects data sent over a computer network and acts on it by rerouting, logging or blocking it. Uses of DPI include;
To ensure that data is in the correct format, internet censorship, to check for malicious code, and also eavesdropping.
DPI uses port mirroring and optical splitter to acquire packets for inspection. It combines the functionality of an intrusion detection system and intrusion prevention system with a traditional stateful firewall.
DPI is therefore helpful in perimeter security by keeping unauthorized users out and at the same time protecting authorized users from attack. Privacy concerns have been raised over the inspection of content layers of internet protocols such as in the case of censorship and government regulations and control.

Answer:
Open ended investigation
Explanation:
The above is an example of an open ended investigation. In understanding what an open ended investigation is, we first of all need to understand what open endedness means. Open endedness means whether one solution or answer is possible. In other words it means that there may be various ways and alternatives to solve or answer a question or bring solution to an investigation.
From the definition, we can deduce that an open ended investigation is a practical investigation that requires students to utilize procedural and substantive skills in arriving at conclusion through evidence gathered from open ended research or experiment(as in not close ended, not limited to ready made options, freedom to explore all possibilities). This is seen in the example question where students are asked to explore the different examples of physical controls and displays and also discuss their observations. Here students are not required to produce a predefined answer but are free to proffer their own solutions
Input a list of positive numbers, find the mean (average) of the numbers, and output the result. Use a subprogram to input the numbers, a function to find the mean, and a subprogram to output the result. Use a subprogram to Input the numbers, a Function to find the mean and a subprogram to output the Result.
Answer:
def inputNumber():
l = []
num = int(input("Enter the number of integers you want to enter\n"))
for i in range(0,num):
print("Enter the ", i+1, " integers ")
a = float(input())
l.append(a)
return l
def averageCalculator(l):
total = 0
for i in l:
total += i
avg = total/len(l)
return avg
def printoutput(avg):
print("The average of numbers is ", avg)
l = inputNumber()
avg = averageCalculator(l)
printoutput(avg)
Explanation:
A subprogram may be considered as a method where we pass some values in the arguments and return some value.
The answer is written in python language, where we have used
inputNumber() subprogram to get the input from the user.
function averageCalculator() to calculate the average.
printoutput() subprogram to print the output or the average of the numbers.
Please refer to the attached image for better understanding of the indentation of code.
Now, let us learn about them one by one:
inputNumber(): We get the number of values to be entered as an integer value and then get the numbers as float.
Store the values in a list and return the list to the caller main program.
averageCalculator(l): Contains a list as argument as we got from inputNumber(). It sums all the numbers and divides with total number to find the average. Returns the average value to the caller main program.
printoutput(avg): Contains an argument which is the average calculated in the averageCalculator(). It prints the argument passed to it.

Define the missing method. licenseNum is created as: (100000 * customID) licenseYear, where customID is a method parameter. Sample output with inputs 2014 777:
Answer:
I am writing the program in JAVA and C++
JAVA:
public int createLicenseNum(int customID){ //class that takes the customID as parameter and creates and returns the licenseNum
licenseNum = (100000 * customID) + licenseYear; //licenseNum creation formula
return(licenseNum); }
In C++ :
void DogLicense::CreateLicenseNum(int customID){ //class that takes the customID as parameter and creates the licenseNum
licenseNum = (100000 * customID) + licenseYear; } //licenseNum creation formula
Explanation:
createLicenseNum method takes customID as its parameter. The formula inside the function is:
licenseNum = (100000 * customID) + licenseYear;
This multiplies 100000 to the customID and adds the result to the licenseYear and assigns the result of this whole expression to licenseNum.
For example if the SetYear(2014) means the value of licenseYear is set to 2014 and CreateLicenseNum(777) this statement calls createLicenseNum method by passing 777 value as customID to this function. So this means licenseYear = 2014 and customID = 777
When the CreateLicenseNum function is invoked it computes and returns the value of licenseNum as:
licenseNum = (100000 * customID) + licenseYear;
= (100000 * 777) + 2014
= 77700000 + 2014
licenseNum = 77702014
So the output is:
Dog license: 77702014
To call this function in JAVA:
public class CallDogLicense {
public static void main(String[] args) {//start of main() function
DogLicense dog1 = new DogLicense();//create instance of Dog class
dog1.setYear(2014); // calls setYear passing 2014
dog1.createLicenseNum(777);// calls createLicenseNum passing 777 as customID value
System.out.println("Dog license: " + dog1.getLicenseNum()); //calls getLicenseNum to get the computed licenceNum value
return; } }
Both the programs along with the output are attached as a screenshot.
Answer:
public int createLicenseNum(int customID){
licenseNum = (100000 * customID) + licenseYear;
return(licenseNum);
}

If the processor has 32 address lines in its address bus; i.e. 32-bit address range, what is its address space or range; i.e. what is the smallest and largest address that can be represented
Answer:
The answer is "0 to 4294967295"
Explanation:
Given bit:
32 bits
Calculating smallest and largest bits:
In any processor, it works only on the 0 and 1 bit and it also stores 0 and 1 values. so, the smallest address in bit value is= 0 and the largest bit value can be defined as follows:
largest address value in bits:
[tex]\Longrightarrow 2^{32}-1\\\\\Longrightarrow 4294967296 -1\\\\\Longrightarrow 4294967295\\\\[/tex]
smallest address= 0
largest address = 4294967295
You bought a monochrome laser printer two years ago. The printer has gradually stopped feeding paper. Which printer component should you check first
Answer:
Pick up roller
Explanation:
you should first check the pickup roller component. This component is the part of the printer that picks paper up from the paper tray. The pickup roller links the printer and the paper. When the printer printer is running, the roller would take paper from the paper tray for the printer to print on. One of the issues it can have is Paper jam where the roller would stop turning so that it will no longer be picking papers up from the tray.
Given an array of integers check if it is possible to partition the array into some number of subsequences of length k each, such that:
Each element in the array occurs in exactly one subsequence
For each subsequence, all numbers are distinct
Elements in the array having the same value must be in different subsequences
If it is possible to partition the array into subsequences while satisfying the above conditions, return "Yes", else return "No". A subsequence is formed by removing 0 or more elements from the array without changing the order of the elements that remain. For example, the subsequences of [1, 2, 3] are D. [1], [2], [3]. [1, 2], [2, 3], [1, 3], [1, 2, 3]
Example
k = 2.
numbers [1, 2, 3, 4]
The array can be partitioned with elements (1, 2) as the first subsequence, and elements [3, 4] as the next subsequence. Therefore return "Yes"
Example 2 k 3
numbers [1, 2, 2, 3]
There is no way to partition the array into subsequences such that all subsequences are of length 3 and each element in the array occurs in exactly one subsequence. Therefore return "No".

Which of the following statements is true of an encrypted file? * The file can be read only by a user with the decryption key The file can be read by the creator and system administrator The file can not be opened again The file can be opened but not read again
Answer:
The file can be read only by a user with the decryption key
Explanation:
The way encryption works is it scrambles the data in a file following the rules of the encryption algorithm using a certain key to tell it how to scramble everything.
Without the key, the computer doesn't know how to decrypt it.
This is true no matter who has access to the file, be it a system administrator, a hacker, or even a legitimate user who has somehow lost access to the key
Strictly speaking, encryption can be broken, but, especially with modern encryption, that's a matter of centuries, and isn't really feasible
The statement that is true of an encrypted file is that The file can be read only by a user with the decryption key.
What is decryption key?A decryption key is known to be a key that is given to Customers by a specific Distributor.
This key allows Customers to open and access the Software that they bought. The decryption key is a mechanism that permit that a file can be read only by a user.

Scams where people receive fraudulent emails that ask them to supply account information are called ________.
Answer:
"Phishing" will be the correct approach.
Explanation:
This aspect of cyber attacks or fraud is called phishing, whereby clients or users are questioned for personally identifiable information about them.Attackers could very well-currently the most frequently use phishing emails to exchange malicious programs that could operate effectively in what seems like several different ways. Others would get victims to steal user credentials including payment details.Generating a signature with RSA alone on a long message would be too slow (presumably using cipher block chaining). Suppose we could do division quickly. Would it be reasonable to compute an RSA signature on a long message by first finding what the message equals (taking the message as a big integer), mod n, and signing that?
Answer:
Following are the algorithm to this question:
Explanation:
In the RSA algorithm can be defined as follows:
In this algorithm, we select two separate prime numbers that are the "P and Q", To protection purposes, both p and q combines are supposed to become dynamically chosen but must be similar in scale but 'unique in length' so render it easier to influence. Its value can be found by the main analysis effectively.
Computing N = PQ.
In this, N can be used for key pair, that is public and private together as the unit and the Length was its key length, normally is spoken bits. Measure,
[tex]\lambda (N) = \ lcm( \lambda (P), \lambda (Q)) = \ lcm(P- 1, Q - 1)[/tex] where [tex]\lambda[/tex] is the total function of Carmichaels. It is a privately held value. Selecting the integer E to be relatively prime from [tex]1<E < \lambda (N)[/tex]and [tex]gcd(E, \lambda (N) ) = 1;[/tex] that is [tex]E \ \ and \ \ \lambda (N)[/tex]. D was its complex number equivalent to E (modulo [tex]\lambda (N)[/tex] ); that is d was its design multiplicative equivalent of E-1.
It's more evident as a fix for d provided of DE ≡ 1 (modulo [tex]\lambda (N)[/tex] ).E with an automatic warning latitude or little mass of bigging contribute most frequently to 216 + 1 = 65,537 more qualified encrypted data.
In some situations it's was shown that far lower E values (such as 3) are less stable.
E is eligible as a supporter of the public key.
D is retained as the personal supporter of its key.
Its digital signature was its module N and the assistance for the community (or authentication). Its secret key includes that modulus N and coded (or decoding) sponsor D, that must be kept private. P, Q, and [tex]\lambda (N)[/tex] will also be confined as they can be used in measuring D. The Euler totient operates [tex]\varphi (N) = (P-1)(Q - 1)[/tex] however, could even, as mentioned throughout the initial RSA paper, have been used to compute the private exponent D rather than λ(N).
It applies because [tex]\varphi (N)[/tex], which can always be split into [tex]\lambda (N)[/tex], and thus any D satisfying DE ≡ 1, it can also satisfy (mod [tex]\lambda (N)[/tex]). It works because [tex]\varphi (N)[/tex], will always be divided by [tex]\varphi (N)[/tex],. That d issue, in this case, measurement provides a result which is larger than necessary (i.e. D > [tex]\lambda (N)[/tex] ) for time - to - time). Many RSA frameworks assume notation are generated either by methodology, however, some concepts like fips, 186-4, may demand that D< [tex]\lambda (N)[/tex]. if they use a private follower D, rather than by streamlined decoding method mostly based on a china rest theorem. Every sensitive "over-sized" exponential which does not cooperate may always be reduced to a shorter corresponding exponential by modulo [tex]\lambda (N)[/tex].
As there are common threads (P− 1) and (Q – 1) which are present throughout the [tex]N-1 = PQ-1 = (P -1)(Q - 1)+ (P-1) + (Q- 1))[/tex], it's also possible, if there are any, for all the common factors [tex](P -1) \ \ \ and \ \ (Q - 1)[/tex]to become very small, if necessary.
Indication: Its original writers of RSA articles conduct their main age range by choosing E as a modular D-reverse (module [tex]\varphi (N)[/tex]) multiplying. Because a low value (e.g. 65,537) is beneficial for E to improve the testing purpose, existing RSA implementation, such as PKCS#1, rather use E and compute D.
