Answer:

knowing how personal data are collected and used.

Explanation:

A database management system (DBMS) can be defined as a collection of software applications that typically enables computer users to effectively and efficiently create, store, modify, retrieve, centralize and manage data or informations in a database. Thus, it allows computer users to efficiently retrieve and manage their data with an appropriate level of security.

Generally, a database management system (DBMS) acts as an intermediary between the physical data files stored on a computer system and any software application or program.

Data theft can be defined as a cyber attack which typically involves an unauthorized access to a user's data with the sole intention to use for fraudulent purposes or illegal operations. There are several methods used by cyber criminals or hackers to obtain user data and these includes DDOS attack, SQL injection, man in the middle, phishing, etc.

Basically, the two (2) essential privacy concerns in the field of cybersecurity are knowing how personal data are collected and essentially how they're used by the beneficiaries or end users.

This ultimately implies that, the medium (channel) and methods through which personal data are collected or obtained plays a huge role in determining how secured or unsecured a user's data are. Also, the manner in which a person's personal data is used should be well defined.

Answer:

The program is as follows:

num = float(input("Enter a decimal (float): "))

mult = int(input("Enter a positive whole (int): "))

small = (num // mult) * mult

big = small + mult

print(num,"rounded to the nearest multiple of ",mult,"is",end=" ")

print(big if num - small > big - num else small)

Explanation:

This gets input for num

num = float(input("Enter a decimal (float): "))

This gets input for mult

mult = int(input("Enter a positive whole (int): "))

This calculates the smaller multiple

small = (num // mult) * mult

This calculates the larger multiple

big = small + mult

This prints the output header

print(num,"rounded to the nearest multiple of ",mult,"is",end=" ")

This prints small if small is closer to num, else it prints big

print(big if num - small > big - num else small)

Explanation:

Microsoft Word refers to a word processing software application or program developed by Microsoft Inc. to enable its users type, format and save text-based documents.

A Mail Merge is a Microsoft Word feature that avails end users the ability to import data from other Microsoft applications such as Microsoft Access and Excel. Thus, an end user can use Mail Merge to create multiple documents (personalized letters and e-mails) for each entry in the list at once and send to all individuals in a database query or table.

Hence, Mail Merge is a Microsoft Word feature that avails users the ability to insert fields from a Microsoft Access database into multiple copies of a Word document.

Some of the options available in the Write & Insert Fields group of Mail Merge are;

I. Highlight Merge Fields.

II. Address Block.

III. Greeting Line.

Generally, when a user wants to launch the Mail Merge help dialog box, the option he or she should select using the Microsoft word office assistant is complete setup.

Additionally, the sequential steps of what occurs during the mail merge process are;

1. You should create the main document

2. Next, you connect to a data source

3. You should highlight or specify which records to include in the mail.

4. You should insert merge fields.

5. Lastly, preview, print, or email the document.

Answer: Dereferencing a variable that is not a pointer

Explanation:

The execution time also refered to as the CPU time pertaining to a given task is the time that is used by the system to execute a task.

Some of the reasons for a fatal execution-time error include:

• Dereferencing a pointer that has not been initialized properly

• Dereferencing a null pointer

• Dereferencing a pointer that has not been assigned to point to a specific address.

It should be noted that dereferencing a variable that is not a pointer doesn't cause a fatal execution-time error.

Answer:

1.Support

In most cases, the simpler the network design, the less technical support you'll require for both installation and maintenance. If you need a complex, high-speed network, consider the level of technical assistance available locally. Many small businesses can't justify the cost of full-time IT personnel. Designing a simple network that can be serviced quickly by local technicians should be a primary consideration. If your business demands a complex network beyond the capabilities of local service, design sufficient redundancy in critical network elements to ensure a minimum level of service until repairs can be made.

2.Expansion

Planning for growth in the initial stages can save future expenditures. The price difference, for example, between a 16-port switch and a 32-port switch can be negligible when compared to the cost of purchasing an new switch to replace one that is too small. Most network devices are designed to provide several years of service.

3.Outside Access

Internet access has become all but mandatory for most modern businesses. It's a good idea to consider the type of Internet connection required and the amount and type of support you will receive from your Internet service provider before designing the rest of your network. Some ISPs will provide support and advice on connection speed requirements and security concerns for commercial accounts before installation.

4.Security

Securing a network from outside intrusion or data theft is a primary concern for many companies. While it is possible to eliminate the expense of Ethernet cabling by opting for a wireless network solution, Wi-Fi networking is the least secure method of sharing data and connections. The encryption methods built into most commercial routers, Wireless Encryption Protocol (WEP), Wireless Protected Access (WPA) and the more recent WPA2, can be cracked by skilled hackers. Designing a network with hard-wired Ethernet connections eliminates the risk of intrusion to only those with physical access to the network.

5.Cost

Equipment and maintenance costs are often the first consideration in network design. Fortunately, the cost of hubs, routers and switches are relatively low when compared to the early days of networking.

Answer:

Explanation:

The following is written in Java and prints out the pattern to and from the first num parameter that is passed to the function. Meaning it goes from num1 to 0 and then from 0 to num1 again. It prints all of the values in a single line seperated by a space and a test case was used using the values provided in the question. The output can be seen in the attached picture below.

static void printNumPattern(int n1,int n2){

       System.out.print(n1 + " ");

       if(n1<=0) {

           return;

       } else {

Answer:

The answer is  "200.5.0.0 32/28".

Explanation:

The requirement of the Bldg is =30.

The number of the host bits which is needed = 5

Therefore the subnet mask will be =/27

for bldg 3 netmask could be= /28

and when the /28 after that the last octet will be= 00100000.

00100000 converting value into a decimal value that is = 32.

therefore the correct value is 200.5.0.32 /28.

Answer:

Answer:

The function is as follows:

public static void printNumber(int nums[],int index){

if (index < 0) {

 System.out.print(nums[0]);

 return;  }

if (index % 2 == 0){

    if(index!=0){

 nums[index-2]*=nums[index];}  }

printNumber(nums, index - 1);

}

Explanation:

To do this, we need to save the required product in the 0 index element of the array.

This defines the function

public static void printNumber(int nums[],int index){

If the index variable < 0,

if (index < 0) {

Print the 0 index as the product [i.e. the calculated product]

 System.out.print(nums[0]);

This ends the recursion

 return;  }

If the current array index is even

if (index % 2 == 0){

Check if index is not 0

    if(index!=0){

If both conditions are valid, calculate the product and save the result in index - 2 element. The final result is then saved in the 0 index

 nums[index-2]*=nums[index];}  }

Call the function while the base case has not been executed

printNumber(nums, index - 1);

}

Answer:

The program is as follows:

import java.util.*;

public class Main{

public static void backward(int [] Rndarray, int lnt){

    System.out.print("Reversed: ");

    for(int itm = lnt-1;itm>=0;itm--){

        System.out.print(Rndarray[itm]+" ");     } }

public static void main(String[] args) {

 Scanner input = new Scanner(System.in);

 int lnt = input.nextInt();

 Random rd = new Random();

 int [] Rndarray = new int[lnt];

 for (int itm = 0; itm < lnt; itm++) {

        Rndarray[itm] = rd.nextInt();

        System.out.print(Rndarray[itm]+" ");

     }

     System.out.println();

 backward(Rndarray,lnt); }}

Explanation:

This defines the backward() method

public static void backward(int [] Rndarray, int lnt){

This prints string "Reversed"

    System.out.print("Reversed: ");

This iterates through the array

    for(int itm = lnt-1;itm>=0;itm--){

Each element is then printed, backwards

        System.out.print(Rndarray[itm]+" ");     } }

The main begins here

public static void main(String[] args) {

 Scanner input = new Scanner(System.in);

This gets the array length

int  n = input.nextInt();

This creates a Random object

Random rd = new Random();

This declares the array

 int [] Rndarray = new int[lnt];

This iterates through the array for input

 for (int itm = 0; itm < lnt; itm++) {

This generates a random number for each array element

        Rndarray[itm] = rd.nextInt();

This prints the generates number

        System.out.print(Rndarray[itm]+" ");

     }

This prints a new line

     System.out.println();

This passes the array and the length to backward() method

 backward(Rndarray,lnt); }}
