Also, suppose that your ISP dynamically assigns your connected device (your wireless router) one IP address. Also suppose that you have six PCs at home that use 802.11 to wirelessly connect to your wireless router. How are IP addresses assigned to the six PCs? Does your wireless router use NAT? Why or why not?
Answer:
The six PCs are assigned private IP addresses via Dynamic Host Configuration Protocol (DHCP)
Yes, the wireless router uses Network Address Translation.(NAT)
Explanation:
Network Address Translation. (NAT) allows a private unregistered network to connect to the internet using one IP address. It is the role of DHCP to assign the private IP addresses to all 6 PCs in the wireless LAN. NAT allows communication between these two different networks by translating the private IP address into a registered public IP address for internet access.
A 'array palindrome' is an array which, when its elements are reversed, remains the same (i.e., the elements of the array are same when scanned forward or backward) Write a recursive, bool-valued function, isPalindrome, that accepts an integer -valued array , and the number of elements and returns whether the array is a palindrome.
An array is a palindrome if:
the array is empty (0 elements ) or contains only one element (which therefore is the same when reversed), or
the first and last elements of the array are the same, and the rest of the array (i.e., the second through next-to-last elements ) form a palindrome.
Answer:
This code is written in MATLAB.
function [result] = isPalindrome(array,length)
if length == 0 || length == 1 %if the array is empty or contains only one element, the array is a palindrome
result = 1;
else
for i = 1:length/2 %check all the elements forward and backward until the middle is reached
if array(i) ~= array(end+1-i)
result = 0;
return
end
end
result = 1;
end
Explanation: Please read the comments in the code. In MATLAB, Boolean values are 1 or 0 instead of True or False.
A researcher wants to do a web-based survey of college students to collect information about their sexual behavior and drug use. Direct identifiers will not be collected; however, IP addresses may be present in the data set. Risk of harm should be evaluated by:___________
Answer:
Severity of harm & Probability of harm
Explanation:
While evaluating the risk of harm in research, two deciding factors are:
1. Magnitude of harm (how severe is the harm)
2. Probability of harm (what are the chances of happening)
Therefore, in this case, it must be analyzed how much harm it can produce for the individual if his information gets leaked along with the chances of occurrence of this event.
Holding an NREMT certification may help you in which of the following situations?A. Establishing protocolsB. Providing prehospital careC. Gaining reciprocityD. Passing an EMT examination
Answer:
Option(c) is the correct answer for the given question.
Explanation:
NREMT certification helps in giving the EMT certification in a very easy manner, due to this we will move in or out to the other state in a very easy manner Holding the NREMT certification gives the practice of the national scope.
Holding an NREMT certification does not mean established protocols, Providing prehospital care it gives the EMT certification we do not need to pass any EMT examination for holding the NREMT certification.So Option(a),Option(b) and Option(d) are incorrect for the prospective point of view of holding an NREMT certification.
Consider the following program segment. ifstream inFile; //Line 1 int x, y; //Line 2 ... //Line 3 inFile >> x >> y; //Line 4 Which of the following statements at Line 3 can be used to open the file progdata.dat and input data from this file into x and y at Line 4?
Answer:
inFile.open("progdata.dat");
Explanation:
This command opens the file which is passed to it as an argument. We are quite used to the C++'s cin and cout functions contained in iostream library for reading and writing data, however, when working will real-life stuff, we find ourselves working with huge data saved as separate files and require our programs to read them, manipulate them and possibly write back to the files... The first operation usually carried out before a file can be read or written to is open
When a policy setting in Computer Configuration and User Configuration in the same GPO conflict, the Computer Configuration policy setting takes precedence. True or False?
Answer:
True
Explanation:
Computer Configuration policy applied first. This happens when the Computer system boots up. Then the user policy is applied when the user logs on. This takes place when the user object is in the same organizational unit.
So Computer Config policy setting takes precedence. User configurations is applied to local users only while computer configuration is applied to the machine itself. First the Computer GPO is applied and then the User GPO. Loopback processing in replace mode enforces the Computer GPO over the user GPO.
Identify an attribute selector used to select an element based on its class value.
Answer:
elem.class is the correct answer for the above question.
Explanation:
In CSS(cascading style sheet), When a user wants to use any property for any attribute and if there are multiple attributes on which he wants to apply the same property then he needs to use the attribute selector based on class.
Just, for example, suppose there is a two image in an HTML document and both need to fill the green color then the user needs to give the same class to both div and use that class property in a CSS to define the green color which can be applied on the image.To use the class property in a CSS, a user needs to define like---
elem.class (where 'elem' is the name of the tag ('img' tag in the above example) and class is the name of the defined class(which is same on the bothe 'img' tag)).The Question asked about the attribute selector of class in CSS and the answer is elem.class, which is defined above.James, a system administrator, is tasked to update the BIOS and firmware of the computer in his organization. What are the reasons to update them?
Answer:
One reason to update BIOS and firmware is to ensure they support new hardware like CPU model or graphic card. In some cases, the updates can also resolve overheating issue or motherboard issue.
However, this is not always the case that we must update the BIOS every time there is a new release because the latest update may cause problem to existing system as well.
As a general rule, only when there are some problems with the existing BIOS and firmware, we are only required to update them.
Updating the BIOS and firmware of computers ensures enhanced security, improved compatibility with new hardware and software, and increased stability and performance, all of which are essential for maintaining an efficient and secure computing environment.
Explanation:James, a system administrator, is tasked with updating the BIOS and firmware of computers in his organization. There are several reasons to perform these updates:
Enhanced Security: Updates can include patches to protect against new vulnerabilities, helping to keep the organization's data safe.Improved Compatibility: Firmware updates may enable hardware to work better with new devices or software, ensuring smooth operations.Increased Stability and Performance: Bug fixes and improvements in the updates can lead to a more stable and efficient computing environment, which is crucial for productivity.Just as an operating system is essential for a computer's operations, keeping system firmware up-to-date ensures the infrastructure of the computers remains reliable, efficient, and sustainable, avoiding the costly disruptions that come with outdated or malfunctioning systems.
entry that has the address of 192.168.101.0 and the wildcard mask of 0.0.0.255. What is the range of IPv4 addresses that will be affected by this ACL?
Answer:
192.168.101.0 through 192.168.101.255 is the correct answer.
Explanation:
The following answer is correct because the address of the ACL entry is 192.168.101.0 and 0.0.0.255 is the wildcard mask then, the range of the IPv4 addresses is 192.168.101.0 through 192.168.101.255 that affected by the ACL.
ACL is referred as the access control list that acts as the firewall which secures the VPC network of the user.
The range of IPv4 addresses affected by the given ACL is from 192.168.101.0 to 192.168.101.255. The wildcard mask of 0.0.0.255 indicates that the last octet can vary from 0 to 255. Therefore, all addresses within this range will be either permitted or denied based on the ACL configuration.
The question pertains to Access Control Lists (ACLs) in network settings using IPv4 addresses. The IPv4 address given, 192.168.101.0, with a wildcard mask of 0.0.0.255, affects a specific range of IP addresses.
Step-by-Step Explanation :
An IPv4 address is a 32-bit address divided into four octets, with each octet represented by a number ranging from 0 to 255. The address 192.168.101.0 falls into this range.A wildcard mask is used in ACLs to specify a range of IP addresses. The given wildcard mask, 0.0.0.255, means that the last octet can vary from 0 to 255.Combining the IPv4 address and the wildcard mask, the range of IP addresses affected includes all addresses from 192.168.101.0 to 192.168.101.255.Therefore, the range of IPv4 addresses that will be affected by this ACL is from 192.168.101.0 to 192.168.101.255.
A data mart differs from a data warehouse in that: Group of answer choices it deals with a particular component or functional area of the business. data mart users do not have the data management expertise of data warehouse employees. Both it has a smaller database and it deals with a particular component or functional area of the business All of these it has a smaller database.
Answer:
A Data Warehouse is a corporate database that integrates purified information from the various sources in the organization. This information must be homogeneous and reliable, it is stored in a way that allows its analysis from many different perspectives, and that it is in turn of the optimal response times. For this, the information is highly denormalized and modeled in a way quite different from transactional systems, mainly the star models (star scheme) and snowflake (snowflake scheme) that we will study later.
A Data Warehouse is much more than what we have commented so far. According to Bill Inmon it is characterized by being:
Theme-oriented: data is organized by topics to facilitate user understanding, so that all data related to the same element of real life is linked together. For example, all customer data can be consolidated in the same table, all product data in another, and so on.
Integrated: the data must be integrated into a consistent structure, eliminating the inconsistencies involved between the various operational systems. The information is structured in various levels of detail to suit the needs of users. Some of the most common inconsistencies that we usually find are: in nomenclature, in units of measure, in date formats, multiple tables with similar information (for example, having several applications in the company, each with customer tables) .
Historical (time variant): the data, which may vary over time, must remain reflected in such a way that these changes are consulted and the reality that was at the time they were stored is not altered, thus avoiding the problem that occurs in the operational systems, that specifically only the state of the present business activity. A Data Warehouse must save the different values that take a variable over time. For example, if a client has lived in three different cities, he must specify the period he lived in each of them and associate the facts (sales, returns, incidents, etc.) that occurred at any time to the city in which He lived when they occurred, and did not associate all historical facts with the city in which he currently lives. If a customer, during all the time we have been selling has gone through three civil states (single, married and divorced) we must know what marital status he had at the time we made each of the sales.
Rebecca completed work on a computer and is verifying the functionality of the system when she finds a new problem. This problem is not urgent and can be easily fixed. The policy at Rebecca’s company is that all problems need to be reported and given a priority code before they can be assigned to someone.What should Rebecca do about this new problem?a. Report the new problem.b. Troubleshoot the new problem.c. Ignore the new problem.d. Determine whether fixing the first problem caused the second problem.
Rebecca should Determine whether fixing the first problem caused the second problem.
d. Determine whether fixing the first problem caused the second problem.
Explanation:
Rebecca completed work on the computer and is verifying the functionality of the system when she finds a new problem.
Keeping in mind the fact that Rebecca's company's policy is that all problems need to be reported and given a priority code before they can be assigned to someone, she should go ahead and determine whether fixing the first problem caused the second problem to arise.
Although the company's policy does not approve of this, before reporting a problem she should check whether the problem is worth the effort. As mentioned, the problem is not urgent and can easily be fixed, she should go ahead with this option.
Which control chart would you use to track rejections in a maintenance projeg when bug arrival pattern is not constant?
Answer:
P chart is the control chart that is used to monitor the rejection or acceptance whenever the bug arrival in pattern is not constant.
Explanation:
In case of only two possible outcomes, such as yes or no, accept or reject, P chart is used as control chart to track rejections. It is used to track rejections whenever the pattern of rejection is not constant. In this type of charts we collect the information from last few days to analyze and predict the next data to track rejections.
For example:
If we want to know that, in admission department of the university, how many students arrives to take admission in university, does not meet the qualification criteria each week. In this case there are only two options available either they meet criteria or not. In this case we use P chart with the help of previous week data to analyze the no. of students who are meeting qualification criteria in this week.

One of the advantages of off-the-shelf software is that ________________. a. the software contains important features, thus eliminating the need for future modification and customization b. b. an organization does not have to pay for features that are not required and never used
Answer:
One of the advantages of off-the-shelf software is that the initial cost is lower because the software firm can spread the development costs over many customers.
Explanation:
Two other choices are missing in the question all choices are:
a. the software contains important features, thus eliminating the need for future modification and customization
b. an organization does not have to pay for features that are not required and never used
c. the software always matches current work processes and data standards.
d. the initial cost is lower because the software firm can spread the development costs over many customers.
Off-the-shelf software can be used by the customer without customization. It is ready made and not developed according to the customer's specifications. Therefore, these software are cheaper than the custom developed software and can easily found and purchased.
Since off-the self software can be used by multiple customers, its initial cost is lower.
Example of off-the-shelf software are Salesforce CRM, Linux operating system, MySQL database, Microsoft Office, anti-virus programs.

What is an IP address?
the 32-bit numeric address identifying a specific computer or device on a network the 30-bit numeric address identifying a group of computers or devices on a network
the 42-bit numeric address identifying a specific computer or device on a network
the 15-bit numeric address identifying a group of computers or devices on a network
Answer:
the 32-bit numeric address identifying a specific computer or device on a network
Explanation:
Ip address is a 32 bit number that is used to identify the computer or devices on the network.
It is the unique address that is assigned to computer or nodes in the network. It is a unique address that helps to send data or packet to the desired destination from any other computer on the network.
It is same like as the address of the home. A unique address is assigned to the home. That cannot be similar to any other home address.
It consist of 32 bits which means that 2^ 32 unique address can be generated with the help of 32 bits.
e.g.
192.168.3.3
The above number is an example of IP address where each digit consist of 8 bits.
NOTE: in mathematics, the square root of a negative number is not real; in C therefore, passing such a value to the square root function is an error. Given a double variable named areaOfSquare write the necessary code to read in a value, the area of some square, into areaOfSquare and print out the length of the side of that square. HOWEVER: if any value read in is not valid input, just print the message "INVALID".
Answer:
# include<math.h>
# include<stdlib.h>
# include<stdio.h>
int main()
{
int choice;
double area;
printf("Enter the area of Square:");
scanf("%lf", &area);
printf("Enter the choice: 1, 2:");
scanf("%d", &choice);
switch(choice)
{
case 1:if(area<0.00)
{
printf(" INVALID");
break;
}
else
{
printf("side of square: %lf", sqrt(area));
break;
}
break;
case 2: break;
}
return 0;
}
Explanation:
Here, if area is less than 0 then invalid message is printed out. And if area is more than 0 then the sqrt is calculated and the side of a square length is being printed out. And that is what is required. lf is for double. And math.h is included to make use of the sqrt function.
