Which network would the patrol services of a city's police department most likely use?

A. LAN
в.PAN
C.CAN
D.MAN

Answers

Answer:

D. MAN

Explanation:

A local area network (LAN) refers to a group of personal computers (PCs) or terminals that are located within the same general area and connected by a common network cable (communication circuit), so that they can exchange information from one node of the network to another. A local area network (LAN) is typically used in small or limited areas such as a set of rooms, a single building, school, hospital, or a set of well-connected buildings. Some of the network devices or equipments used in a local area network (LAN) includes an access point, personal computers, a switch, a router, printer, etc.

On the other hand, a metropolitan area network (MAN) is formed by an aggregation of multiple local area network (LAN) that are interconnected using backbone provided by an internet service provider (ISP). A metropolitan area network (MAN) spans for about 5 kilometers to 50 kilometers in size.

Basically, a metropolitan area network (MAN) spans across a geographic area such as a city and it's larger than a local area network (LAN) but significantly smaller than a wide area network (WAN).

In conclusion, the network type that the patrol services of a city's police department would most likely use is a metropolitan area network (MAN).

A. Malicious code.
B. Hoaxes.
C. Spoofing.
D. Sniffer.

Answers

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.

When computer users have trouble with their machines or software, Roland is the first person they call for help. Roland helps users with their problems, or refers them to a more-experienced IT employee. Roland holds the position of __________ in the organization. Support Analyst Systems Analyst Network Administrator Database Administator

Answers

Answer:

The correct answer is A) Support Analyst

Explanation:

From the question, we can see that Roland is familiar with both machines and software. He is familiar with the operations of both parts of a computer to the end that he can attempt a fix. And if he can't he knows who to refer the end-users to. Usually, some IT personnel that is more experienced.

From the above points, we can safely say that Roland is an IT Support Analyst. He cannot be the Systems analyst because Systems Analysts are usually at the top of the Pyramid. They take on problems that are referred upwards to them from support analysts.

A recursive method may call other methods, including calling itself. A recursive method has:
1. a base case -- a case that returns a value or exits from a method without performing a recursive call.
2. a recursive case -- calling the method again with a smaller case..
Study the recursive method given below.
For example, this call recursiveMethod (5); returns 15:
public static int recursiveMethod (int num) (
if (num == 0)
return 1;
else {
if (numX2!=0)
return num * recursiveMethod (num -1);
else
return recursiveMethod (num-1);
}
}
1 What is the base case?
2. What does the following statement check?
3. What does the method do?

Answers

Answer:

Hence the answer is given as follows,

Explanation:

Base Case:-  

If (num == 0) //This is the base case for the given recursive method  

return 1;  

If(num % 2!=0) checks whether num is odd.  

The above condition is true for all odd numbers and false for even numbers.  

if the remainder is not equal to zero when we divide the number with 2 then it is odd.  

The method:-  

The above recursive method calculates the product of odd numbers up to the given range(that is num)  

For num=5   => 15(5*3*1).  

For num=7   => 105(7*5*3*1).  

For num=10 => 945(9*7*5*3*1).

Answers

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

   user_num = user_num // x#dividing the value and store integer part

   print(user_num)#print value

Output:

Explanation:

In the above-given program code two-variable "user_num and x" is declared that inputs the value from the user-end and define a for loop that uses the "j" variable with the range method.

In the loop, it divides the "user_num" value with the "x" value and holds the integer part in the "user_num" variable, and prints its value.

The valid call to the function installApplication is

{
 // call the function installApplication
}

void installApplication(char appInitial, int appVersion)
{
  // rest of function not important
}

Answers

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

Answers

The output is:

Explanation:

Given

See attachment for code segment

Required

The output of rec2(5)

From the attached code segment, we have the following:

The base case: if (x==0){ return;}

The above implies that, the recursion ends when the value of x gets reduced to 0

The recursion:

rec2(x-1); ---- This continually reduces x by 1 and passes the value to the function

printf("%d ", x); This prints the passed value of x

Hence, the output of rec2(5) is: 1 2 3 4 5

Write a program that will read two floating point numbers (the first read into a variable called first and the second read into a variable called second) and then calls the function swap with the actual parameters first and second. The swap function having formal parameters number1 and number2 should swap the value of the two variables.
Sample Run:
Enter the first number
Then hit enter
80
Enter the second number
Then hit enter
70
You input the numbers as 80 and 70.
After swapping, the first number has the value of 70 which was the value of the
second number
The second number has the value of 80 which was the value of the first number

Answers

Answer:

The program in Python is as follows:

def swap(number1,number2):

   number1,number2 = number2,number1

   return number1, number2

   

first = int(input("First: "))

second = int(input("Second: "))

print("You input the numbers as ",first,"and",second)

first,second= swap(first,second)

print("After swapping\nFirst: ",first,"\nSecond:",second)

Explanation:

This defines the function

def swap(number1,number2):

This swaps the numbers

   number1,number2 = number2,number1

This returns the swapped numbers

   return number1, number2

The main begins here

This gets input for first    

first = int(input("First: "))

This gets input for second

second = int(input("Second: "))

Print the number before swapping

print("You input the numbers as ",first,"and",second)

This swaps the numbers

first,second= swap(first,second)

This prints the numbers after swapping

print("After swapping\nFirst: ",first,"\nSecond:",second)
