Many companies possess valuable information they want to guard closely (ex. new chip design, competition plans, legal documents). Personal computer hard disks these days are full of important photos, videos, and movies. As more and more information is stored in computer systems, the need to protect it is becoming increasingly important. Which of the following statements is incorrect with respect to Security?
a. security has many facets; three of the more important ones are: the nature of the threats, the nature of intruders, and cryptography
b. data integrity means that unauthorized users should not be able to modify any data without the owner's permission
c. a common category of intruders are driven by determined attempts to make money; for example: bank programmers attempting to steal from the bank they work for
d. in addition to threats caused by malicious users, data can be lost by accident; for example: rats gnawing backup tapes
Answer: D. in addition to threats caused by malicious users, data can be lost by accident; for example: rats gnawing backup tapes
Explanation:
Data security is essential to protecting unwanted people from having access to ones data, malicious attack should also be prevented and unusual behavior should be monitored.
Data security has many facets such as threat nature, the nature of intruders, and cryptography. Furthermore, data integrity means that unauthorized users should not be able to modify any data without the owner's permission. Also, the statement that a common category of intruders are driven by determined attempts to make money; for example: bank programmers attempting to steal from the bank they work for is correct.
It should be no noted that rats gnawing backup tapes cannot prevent data loss. Therefore, the correct option is D

Explanation:The function strpos() is a function in php that returns the position of the first occurrence of a particular substring in a string. Positions are counted from 0. The function receives two arguments. The first argument is the string from which the occurrence is to be checked. The second argument is the substring to be checked.
In this case, the string is "Get Well Soon!" while the substring is "Well"
Starting from 0, the substring "Well" can be found to begin at position 4 of the string "Get Well Soon!".
Therefore, the function strpos("Get Well Soon!", "Well") will return 4.
Then, with the echo statement, which is used for printing, value 4 will be printed as output of the code.
True or false, an implicitly unwrapped optional variable must have an exclamation mark affixed after it every time it is used. 答案选项组
Answer:
False.
Explanation:
Implicit unwrapped optional variables are those which are at option and they might be nil. It is not necessary that all implicit unwrapped optional variables should have an exclamation mark. Swift may eliminate the need for unwrapping.
The valid call to the function installApplication is
void main( )
{
// call the function installApplication
}
void installApplication(char appInitial, int appVersion)
{
// rest of function not important
}
Answer:
B. installApplication(‘A’, 1);
Explanation:
Given
The above code segment
Required
The correct call to installApplication
The function installApplication is declared as void, meaning that it is not expected to return anything.
Also, it receives a character and an integer argument.
So, the call to this function must include a character and an integer argument, in that order.
Option D is incorrect because both arguments are integer
Option C is incorrect because it passes no argument to the function.
Option A is incorrect because it receives an integer value from the function (and the function is not meant not to have a return value).
Option B is correct
why concurrency control is needed in transaction.
And why Acid properties in transaction is important.
Explanation:
Concurrency Control in Database Management System is a procedure of managing simultaneous operations without conflicting with each other. It ensures that Database transactions are performed concurrently and accurately to produce correct results without violating data integrity of the respective Database.And The ACID properties, in totality, provide a mechanism to ensure correctness and consistency of a database in a way such that each transaction is a group of operations that acts a single unit, produces consistent results, acts in isolation from other operations and updates that it makes are durably stored.

var num2 = 32;
var num1 = 12;
var rem=num2 % numi;
while(rem > 0)
{
num2 = num1;
num1 = rem;
rem = num2 % num1;
}
document.write(num1);
The output of the document.write statement at the end of this block is
Answer:
4
Explanation:
Given
The attached code segment
Required
The output
The first and second lines initialize num2 to 32 and num1 to 12, respectively.
Next, the remainder is calculated on line 3
[tex]rem = 32\%12[/tex]
[tex]rem = 8[/tex]
Then the while loop is repeated as long as rem > 0.
At first, we have:
[tex]num2 = 32[/tex]
[tex]num1 = 12[/tex]
[tex]rem = 8[/tex]
The first iteration gives:
[tex]num2 = 12[/tex]
[tex]num1 = 8[/tex]
[tex]rem = 12\%8 = 4[/tex]
Is 4 > 0? Yes; The loop is executed again.
This gives:
[tex]num2 = 8[/tex]
[tex]num1 = 4[/tex]
[tex]rem = 8\%4=0[/tex]
Is 0 > 0? No; The loop is executed
The last statement prints the last value of num1;
In the last loop, we have:
[tex]num1 = 4[/tex]
Hence, the output is 4

Multiplexing gets allowed by the transport layer which enables to transfer messages over a network and also the error and corrected data.
Gray London is a retired race car driver who helped Dale Earnhardt, Jr. get his start. He is writing a book and making a video about the early days or Dale Earnhardt. He is trying to decide whether to market these items directly over the Internet or to use intermediaries. To make this decision, he needs to know the pros and cons of each route. Provide that information and make a recommendation to him.
Answer:
Explanation:
Marketing your product directly over the internet can lead to much greater profits and there are many options that you can choose from in order to target the correct audience. Unfortunately, doing so does require marketing knowledge and is basically like growing a business. If you were to use intermediaries they already have the knowledge necessary to market your product but will take a percentage of the profits, which will ultimately limit your gains. Since Gray London is a race car driver, I am assumming that he does not have any prior technological expertise or marketing expertise, therefore I would recommend using intermediaries.
A(n) _____ is a network connection device that can build tables that identify addresses on each network.
Answer:
Dynamic Router
Explanation:
A dynamic router is a network connection device that can build tables that identify addresses on each network.
What is Dynamic network?Dynamic networks are networks that vary over time; their vertices are often not binary and instead represent a probability for having a link between two nodes.
Statistical approaches or computer simulations are often necessary to explore how such networks evolve, adapt or respond to external intervention.
DNA statistical tools are generally optimized for large-scale networks and admit the analysis of multiple networks simultaneously in which, there are multiple types of nodes (multi-node) and multiple types of links (multi-plex).
Therefore, A dynamic router is a network connection device that can build tables that identify addresses on each network.

Ex: 6 // 4 is 1 (the 0.5 is discarded).LAB ACTIVITY2.29.1: LAB: Divide by x0 / 10main.pyLoad default template...12''' Type your code here. '''
Answer:
Following are the code to the given question:
user_num = int(input())#defining a variable user_num that takes input from user-end
x = int(input())#defining a variable x that takes input from user-end
for j in range(3):#defining for loop that divides the value three times
user_num = user_num // x#dividing the value and store integer part
print(user_num)#print value
Output:

using namespace std;
class PersonData {
public:
void SetName(string userName) {
lastName = userName;
};
void SetAge(int numYears) {
ageYears = numYears;
};
// Other parts omitted
void PrintAll() {
cout << "Name: " << lastName;
cout << ", Age: " << ageYears;
};
private:
int ageYears;
string lastName;
};
class StudentData: public PersonData {

void SetID(int studentId) {
idNum = studentId;
};
int GetID() {
return idNum;
};
private:
int idNum;
};
int main() {
StudentData courseStudent;
/* Your solution goes here */
return 0;
}
Answer:
Replace /* Your solution goes here */
with the following:
courseStudent.SetName("Smith");
courseStudent.SetAge(20);
courseStudent.SetID(9999);
courseStudent.PrintAll();
cout <<courseStudent.GetID();
Explanation:
From the given code segment, we have the following methods defined under the StudentData class;
SetName -> It receives name from the main
SetAge -> It receives age from the main
SetID --> It receives ID from the main and passes it to GetID method
printID --> Prints all the required output.
So, we have:
Pass name to setName
courseStudent.SetName("Smith");
Pass age to setAge
courseStudent.SetAge(20);
Pass ID to setID
courseStudent.SetID(9999);
Print all necessary outputs
courseStudent.PrintAll();
Manually print the student ID
cout <<courseStudent.GetID();

A. Malicious code.
B. Hoaxes.
C. Spoofing.
D. Sniffer.
Answer:
C. Spoofing.
Explanation:
Cyber security can be defined as preventive practice of protecting computers, software programs, electronic devices, networks, servers and data from potential theft, attack, damage, or unauthorized access by using a body of technology, frameworks, processes and network engineers.
Some examples of cyber attacks are phishing, zero-day exploits, denial of service, man in the middle, cryptojacking, malware, SQL injection, spoofing etc.
Spoofing can be defined as a type of cyber attack which typically involves the deceptive creation of packets from an unknown or false source (IP address), as though it is from a known and trusted source. Thus, spoofing is mainly used for the impersonation of computer systems on a network.
Basically, the computer of an attacker or a hacker assumes false internet address during a spoofing attack so as to gain an unauthorized access to a network.

Full question:
Provide the EXACT C++ line of code necessary to return the heap-dynamic variable ptr to the operating system.
Pokemon *ptr;
ptr = new Pokemon[6];
Answer:
delete ptr;
Explanation:
The command in the answer above deallocates memory(preventing memory leaks) and returns control to the operating system.
The command in the question dynamically allocates memory to the the heap(dynamically allocated memory is called heap) while the program is running(different from statically allocated memory that allocates before program compiles). When the variable is no longer needed, deallocation occurs using the command in our answer where the variable is deleted using the pointer(keeps track of dynamic variables).
