Which of the following is given to a notification from a firewall that a specific event or packet was detected?
a. management interface
b. rules
c. alert
d. anomaly-based detection

Answers

Answer 1

Option C Alert

How do firewall work?A firewall is a piece of network security equipment that keeps an eye on both incoming and outgoing network traffic and allows or denies data packets in accordance with a set of security rules. Its goal is to create a physical barrier between your internal network and incoming traffic from outside sources (like the internet), blocking unwanted traffic like that of hackers and viruses.In order to stop attacks, firewalls thoroughly examine incoming communication in accordance with pre-established criteria and filter traffic from untrusted or dubious sources. Firewalls monitor traffic at a computer's ports, which are the entry points via which data is shared with external devices. Such a statement might read, "Source address 172.18.1.1 is allowed to reach destination 172.18.2.1 through port 22."Consider port numbers as the rooms in the home and IP addresses as the houses. It is further filtered such that persons inside the house are only permitted to access specific rooms (destination ports), depending on whether they are the owner, a child, or a visitor. Only trusted people (source addresses) are allowed to enter the house (destination address) at all. While kids and visitors are not permitted in any room (or port), the owners are permitted to enter a specific set of rooms (specific ports).

b. 12 meters =
yards
c. 10 quarts =
liters
d. 12 milliliters =
fluid oz
e. 400 pounds =
kilograms
f. 25 meters/second =
feet/second

Answers

Answer:

a. 25.4 millimeters

b.13.1234 yards

c.9.4635295 liters

d.0.405678 fluid oz.

e.181.437 kilogram

f.82.021 feet/s

Explanation:

(a). 1 inch is equal to 25.4 millimeter (mm) .To convert inches to millimeter multiply the inch value by 25.4 i.e., 1 inch= 1 × 25.4=25.4 mm

(b).1 meter is equal to 1.094 yard. To convert meter to yard multiply the meter value by 1.094 i.e., 12 m= 12 × 1.094=13.1234 yards

(c) 1 quart =0.946352 liters . To convert quart to liters divide the volume value by 1.056 i.e., \(10 quarts=\frac{10}{1.056} =9.4635 liters\)

(d).1 fluid oz.= 29.5739 milliliters. To convert milliliters to fluid oz. divide the volume value by 29.5739 i.e., \(12 ml=\frac{12}{29.5735} =0.405678 fluid oz\)

(e).1 kg= 2.204 pounds .To convert pounds to kilograms divide the mass value by 2.204 i.e. , \(400 pounds =\frac{400}{2.204}=181.437 kilogram\)

(f).1 meters/second is equal to 3.28024 foot/second. To convert meters/second to feet/second multiply speed value by 3.280 i.e., \(25 meters/second =25 * 3.28024 =82.021 feet/second\)

Write a method that takes a single integer parameter that represents the hour of the day (in 24 hour time) and prints the time of day as a string. The hours and corresponding times of the day are as follows:

0 = “midnight”
12 = “noon”
18 = “dusk”
0-12 (exclusive) = “morning”
12-18 (exclusive) = “afternoon”
18-24 (exclusive) = “evening”

You may assume that the actual parameter value passed to the method is always between 0 and 24, including 0 but excluding 24.
This method must be called timeOfDay()and it must have an integer parameter.

Calling timeOfDay(8) should print “morning” to the screen, and calling timeOfDay(12) should print “noon” to the screen.

You can call your method in the program's main method so you can test whether it works, but you must remove or comment out the main method before checking your code for a score.

def timeOfDay(hour):

  if hour == 0:

Write a recursive program that calculates the total tuition paid over certain number of years. The tuition goes up by 2.5% per year. This method does not return any value. It displays the information and here is the call to the method and the sample output.

Answers

Answer:

The program is as follows:

def calctuit(pay,n,yrs):

   if n == 0:

       return

   pay*=(1.025)

   print("Year ",yrs,": ",pay)

   calctuit(pay,n-1,yrs+1)

n = int(input("Years: "))

pay = float(input("Tuition: "))

yrs = 1

calctuit(pay,n,yrs)

Explanation:

The function begins here

def calctuit(pay,n,yrs):

This represents the base case

   if n == 0:

       return

This calculates the tuition for each year

   pay*=(1.025)

This prints the tuition

   print("Year ",yrs,": ",pay)

This calls the function again (i.e. recursively)

   calctuit(pay,n-1,yrs+1)

The function ends here

This gets the number of years

n = int(input("Years: "))

This gets the tuition

pay = float(input("Tuition: "))

This initializes the years to 1

yrs = 1

This calls the function

calctuit(pay,n,yrs)

What security weaknesses/vulnerabilities exist in Wireless local area network device hardware and software?

Default Network Hardware, many individuals will go out and buy a new router and install it in their home. These devices come with a preset configuration including a preset security password which is many times a default password used for every router of the same model. This can be easily obtained by anyone who can then access the network.

Access Point hacking, an experienced individual can use a packet sniffer to detect the SSID that is frequently sent from the router in order to create an access point to be able to access the network.

WEP encryption is another vulnerability. These are very low security passwords that can be cracked using different software in a short period of time.

In this c++ assignment, add an undo feature to a list of strings.


Here's a working class called Stringlist that implements a simple string list as a dynamic array. Stringlist_test.cpp has tests for all the methods in Stringlist.


Stringlist has one unimplemented method:

// Undoes the last operation that modified the list. Returns true if a

// change was undone, false otherwise.

//

bool undo()

{

cout << "Stringlist::undo: not yet implemented\n";

return false;

}

Your job is to implement undo, thus making Stringlist an undoable list.


Your implementation must follow these rules:


Do not delete any methods, or change the signatures of any methods, in Stringlist. You can change the implementation of existing methods if necessary. But they should still work the same way: your finished version of Stringlist with undo implement must still pass all the tests in Stringlist_test.cpp.

You can add other helper methods (public or private), functions, and classes/structs to Stringlist.h if you need them.

You must implement undo() using a private stack that is accessible only inside the Stringlist class. Implement the stack yourself as a linked list. Do not use arrays, vectors, or any other data structure for your stack.

Do not use any other #includes or #pragmas in Stringlist.h other than the ones already there.

When it's done, you'll be able to write code like this:


#include "Stringlist.h"

#include


using namespace std;


int main() {

Stringlist lst;

cout << lst << endl; // {}


lst.insert_back("one");

lst.insert_back("two");

lst.insert_back("three");

cout << lst << endl; // {"one", "two", "three"}


lst.undo();

cout << lst << endl; // {"one", "two"}


lst.undo();

cout << lst << endl; // {"one"}


lst.undo();

cout << lst << endl; // {}

}


Designing the Undo Stack


As mentioned above, you must implement undo() using at least one private stack implemented as a linked list inside the Stringlist class. You can modify Stringlist only as described at the start of this assignment.


examples of how specific methods should work.


Undoing insert_before


In code:


// lst == {"dog", "cat", "tree"}


lst.insert_before(3, "hat");

// lst == {"dog", "cat", "tree", "hat"}


lst.undo();

// lst == {"dog", "cat", "tree"}


lst.insert_before(1, "shoe");

// lst == {"dog", "shoe", "cat", "tree"}


lst.undo();

// lst == {"dog", "cat", "tree"}

Undoing set


For set, suppose that lst is {"yellow", "green", "red", "orange"}, and so lst.get(2) returns "red". If you call lst.set(2, "cow"), then you should push the operation set location 2 to "red" onto the undo stack, and then over-write location 2 with "cow".


In code:


// lst == {"yellow", "green", "red", "orange"}


lst.set(2, "cow");

// lst == {"yellow", "green", "cow", "orange"}


lst.undo();

// lst == {"yellow", "green", "red", "orange"}

Undoing remove_at


For remove_at

In code:


// lst == {"dog", "cat", "tree"}


lst.remove_at(1);

// lst == {"dog", "tree"}


lst.undo();

// lst == {"dog", "cat", "tree"}

Undoing operator=


For operator=,

In code:


// lst1 == {"dog", "cat", "tree"}

// lst2 == {"yellow", "green", "red", "orange"}


lst1 = lst2;

// lst1 == {"yellow", "green", "red", "orange"}

// lst2 == {"yellow", "green", "red", "orange"}


lst1.undo();

// lst1 == {"dog", "cat", "tree"}

// lst2 == {"yellow", "green", "red", "orange"}

As this shows, when you undo operator=, the entire list of strings is restored in one call to undo().


Important notes:


If lst1 and lst2 are different objects, then when lst2 is assigned to lst1 just the underlying string array of lst2 is copied to lst1. The lst1 undo stack is updated so that it can undo the assignment. The undo stack of lst2 is not copied, and lst2 is not modified in any away.


Self-assignment is when you assign a list to itself, e.g. lst1 = lst1;. In this case, nothing happens to lst1. Both its string data and undo stack are left as-is.


Undoing remove_all


For remove_all,

In code:


// lst == {"dog", "cat", "tree"}


lst.remove_all();

// lst == {}


lst.undo();

// lst == {"dog", "cat", "tree"}

Note that it should work the same way when lst is empty:


// lst == {}


lst.remove_all();

// lst == {}


lst.undo();

// lst == {}

Undoing Other Methods


undo() should undoall the other methods in Stringlist that are marked as "undoable" in the source code comments.


As mentioned above, undo() is not undoable. There is no "re-do" feature in this assignment.


Each method in Stringlist.h marked "undoable" should work correctly with undo(). This also includes the correct behaviour for the Stringlist copy constructor (which should not copy the undo stack).

The markers tests should run correctly, including with no memory leaks according to valgrind.

Answers

To implement the undo feature in the Stringlist class, you will need to modify the existing class and add a private stack implemented as a linked list. Here are the steps to follow:

How to write the program code

1. In the Stringlist class in Stringlist.h, add a private struct called `UndoNode` to represent each node in the undo stack. Each node should store the necessary information to undo an operation (e.g., the method name, the arguments, and any other relevant data).

```cpp

private:

   struct UndoNode {

       std::string method;  // The method name

       // Add other necessary data for the specific method being undone

       // ...

       UndoNode* next;  // Pointer to the next node in the stack

       UndoNode(const std::string& m) : method(m), next(nullptr) {}

   };

```

2. Add a private member variable `undoStack` of type `UndoNode*` to the Stringlist class to keep track of the undo stack.

```cpp

private:

   // Other private member variables

   UndoNode* undoStack;

```

3. Modify the undoable methods in the Stringlist class to push the necessary information onto the undo stack before performing the operation. For example, in the `insert_before` method:

```cpp

void insert_before(size_t index, const std::string& str) {

   // Push the operation onto the undo stack

   UndoNode* undoNode = new UndoNode("insert_before");

   // Add necessary data to the undoNode (e.g., index and str)

   // ...

   // Perform the actual operation

   // ...

   // Add the undoNode to the top of the stack

   undoNode->next = undoStack;

   undoStack = undoNode;

}

```

4. Implement the `undo` method to pop the top node from the undo stack and perform the undo operation based on the stored information. You will need to handle each operation individually in the `undo` method.

```cpp

bool undo() {

   if (undoStack == nullptr) {

       std::cout << "Undo stack is empty." << std::endl;

       return false;

   }

   UndoNode* undoNode = undoStack;

   undoStack = undoStack->next;

   // Perform the undo operation based on the stored information in undoNode

   if (undoNode->method == "insert_before") {

       // Undo the insert_before operation

       // ...

   } else if (undoNode->method == "set") {

       // Undo the set operation

       // ...

   }

   // Handle other operations...

   delete undoNode;

   return true;

}

```

Remember to handle memory deallocation appropriately and update other methods marked as "undoable" accordingly.

Should Manufacturers Include Extra Programs in Operating Systems for Computers and Mobile Devices?

Answers

Answer:

Well, it depends. Sometimes the extra programs can be useful or just plain fun, in which case the answer is yes. But extra programs can also sometimes be utterly useless and get in the way, in which case the answer is no.\

The development of software for computers benefits greatly from an operating system.

What is operating systems?

Without an operating system, each program would have to contain both its own user interface (UI) and the complete code required to manage all low-level computer operations, such as disk storage, network connections, and other things.

This would greatly increase the size of any application and render software development difficult given the wide variety of underlying hardware available.

Instead, a lot of routine operations, such transmitting a network packet or showing text on a display or other conventional output device, can be delegated to system software, which acts as a bridge between applications and hardware.

Applications can interact with the system in a predictable and consistent manner thanks to the system software.

Therefore, The development of software for computers benefits greatly from an operating system.

How did early computing device such as Charles Babbage's analytical engine and Ada Lovelace's contributions set the foundation for modern computing

Answers

Early computing devices, such as Charles Babbage's Analytical Engine and Ada Lovelace's contributions, played a crucial role in setting the foundation for modern computing. Here's how their work contributed to computing development:

1. Charles Babbage's Analytical Engine: Babbage designed the Analytical Engine, a mechanical general-purpose computer concept, in the 19th century. Although the Analytical Engine was never fully built, its design and principles laid the groundwork for modern computers. Key features of the analytical engine include:

a. Stored Program: Babbage's Analytical Engine introduced the concept of storing instructions and data in memory, allowing complex calculations and tasks.

b.  Control Flow: The Analytical Engine could make decisions and perform conditional operations based on previous computations, resembling the modern concept of control flow in programming.

c. Loops: Babbage's design incorporated looping mechanisms, enabling repetitive instruction execution, similar to modern programming languages.

2. Ada Lovelace's Contributions: Ada Lovelace, an English mathematician, collaborated with Charles Babbage and made significant contributions to computing. Her work on Babbage's Analytical Engine included writing the first algorithm intended for machine implementation. Lovelace realized the potential of the analytical engine beyond numerical calculations and recognized its capability for processing symbols and creating complex algorithms. Her insights laid the foundation for computer programming and algorithms.

Lovelace's ideas about the analytical engine extended beyond what was initially envisioned. He stressed the importance of machines handling more than just numbers. Her contributions demonstrated computers' potential to perform tasks beyond basic calculations and numerical processing.

Collectively, Babbage's analytical engine and Lovelace's contributions provided early conceptual frameworks for modern computing. Their ideas influenced subsequent pioneers in the field, and the concepts they introduced paved the way for the development of the digital computers we use today.

Display “Welcome to (your name)’s fuel cost calculator.”

Ask the user to enter name of a trip destination.

Ask the user to enter the distance to that trip destination (in miles) and the fuel efficiency of their car (in mpg or miles per gallon).

Calculate the fuel required to get to destination and display it.

Use the formula: Fuel amount = Distance / Fuel efficiency, where Fuel is in gallons, Distance is in miles and Fuel efficiency is in miles per gallon.

Your program should follow Java convention for variable names (camelCase).

Ask the user to enter fuel price (in dollars per gallon) in their area.

Compute trip cost to get to destination and display it.

Use the formula: Trip fuel cost = Fuel amount x Fuel price, where trip fuel cost is in dollar amount, fuel is in gallons, and fuel price is in dollars per gallon.

You need to convert this mathematical formula to a Java statement. Be sure to use the right operator symbols! And, as before, follow Java convention for variables names (camelCase).

Compute and display total fuel cost for round trip, to reach and return from destination, using the formula: Round Trip Fuel Cost = 2 x Trip fuel cost

You need to convert this mathematical formula to a Java statement!

Compute and display number of round trips possible to Nashville, 50 miles away, with $40 worth of fuel. Use the fuel efficiency and fuel price entered by user earlier. Perform the computation in parts:

One can compute how much fuel can be bought with $40 from:

Fuel bought = Money available / Fuel cost = 40 / Fuel price, where fuel bought is in gallons and fuel price is in dollars per gallon.

One can compute fuel required for one round trip:

Fuel round trip = 2 * distance / fuel efficiency = 2 * 50 / fuel efficiency, where fuel round trip is in gallons and fuel efficiency is in miles per gallon

Compute number of round trips possible by dividing the amount of fuel that can be bought by the amount of fuel required for each round trip (Formula: round trips = fuel bought / fuel round trip).

Note that this value should be a whole number, and not a fraction.

Use integer division! Type cast the division quotient into int by writing (int) in front of the parenthesized division.

Integer numValues is read from input. Then numValues integers are read and stored in vector benefitsList. Write a loop that assigns each element in benefitsList that is less than 100 with twice the element's current value.

Ex: If the input is 3 19 121 233, then the output is:

Raw benefits: 19 121 233
Adjusted benefits: 38 121 233

in c++

Answers

Loop that assigns each element in benefitsList that is less than 100 with twice the element's current value is:

for(int i=0; i<numValues; i++){

 if(benefitsList[i] < 100){

   benefitsList[i] = benefitsList[i] * 2;

 }

}

In C++, the loop to assign each element in 'benefitsList' that is less than 100 with twice the element's current value can be written as follows:

#include <iostream>

#include <vector>

using namespace std;

int main() {

  int numValues;

  cin >> numValues;

vector<int> benefitsList(numValues);

for (int i = 0; i < numValues; ++i) {

     cin >> benefitsList.at(i);

  }

 cout << "Raw benefits: ";

  for (int val : benefitsList) {

     cout << val << " ";

  }

  cout << endl;

cout << "Adjusted benefits: ";

  for (int i = 0; i < numValues; ++i) {

     if (benefitsList.at(i) < 100) {

        benefitsList.at(i) *= 2;

     }

     cout << benefitsList.at(i) << " ";

  }

  cout << endl;

return 0;

}

The loop checks each element in 'benefitsList' and multiplies it by 2 if it is less than 100.

The updated 'benefitsList' is then printed to the console.

In the given example, the output would be:

Raw benefits: 19 121 233
