Answers

Answer 1

Answer: D. all of the above are correct

Explanation:

The correct statements regarding the decentralized (distributed) access control on a LAN include:

• no centralized access process exists, and therefore each connected station has the responsibility for controlling its access

• data collisions are possible, therefore mechanisms such as CDMA/CD are required

• when a data collision occurs, the nearest station detecting the collision transmits a jamming signal.

Therefore, the correct option is all of the above.

A desktop computer is a type of mobile device: B. False.

What is a desktop computer?

A desktop computer simply refers to an electronic device that is designed and developed to receive data in its raw form as an input and processes these data into an output that's usable by an end user.

Generally, desktop computers are fitted with a power supply unit (PSU) and designed to be used with an external display screen (monitor) unlike mobile device.

In conclusion, a desktop computer is not a type of mobile device.

1. Create a pseudocode program that asks students to enter a word. Call a function to compute the different ways in which the letters that make up the word can be arranged.
2. Convert the pseudocode in question one to JavaScript and test your program.

Answers

Answer:

1)Pseudocode:-

Prompt user to enter string

Pass it to combination function which can calculate the entire combination and can return it in an array

In combination method -

Check if the string is length 2 size ie of 0 or 1 length then return string itself

Else iterate through string user entered

Get the present character within the variable and check if the variable is already used then skip

Create a string from 0 to i the index + (concatenate) i+1 to length and recursive call combination function and pass this string and store end in subpermutation array

For each recursive call push character + sub permutation in total arrangement array.

2)Code -

function combinations(userStr) {

   /* when string length is less than 2 then simply return string */

   if (userStr.length < 2) return userStr;

   /* this array will store number of arrangement that word can be stored */

   var totalArrangements = [];

   /* iterate through string user enter  */

   for (var i = 0; i < userStr.length; i++) {

       /* get the current  character  */

       var character = userStr[i];

       /*check if character is already used than skip  */

       if (userStr.indexOf(character) != i)

           continue;

       /* create a string and concanete it form  0  to i index and i+1 to length of array   */

      var str = userStr.slice(0, i) + userStr.slice(i + 1, userStr.length);

       /* push it to totalArrangments  */

       for (var subPermutation of combinations(str))

           totalArrangements.push(character + subPermutation)

   }

   /* return the total arrangements */

   return totalArrangements;

}

/* ask user to prompt string  */

var userStr = prompt("Enter a string: ");

/* count to count the total number of combinations */

let count = 0;

/* call function the return tolal number of arrangement in array */

totalArrangements = combinations(userStr);

/* print the combination in console  */

for (permutation of totalArrangements) {

   console.log(permutation)

}

/* total combination will be  totalArrangements.length */

count = totalArrangements.length;

/*print it to console  */

console.log("Total combination " + count)

b) if (c < 0)

print (yes);

else

print (maybe);

What is the pseudo-code

In assembly code, the command cmp AH, c checks if the high byte of the EAX register (AH) has the same value as the variable c. Then, if the value in AH is more than the value in c, the instruction jg option1 will move to option1.

Therefore, In the pseudo-code, one can check if c is smaller than 0. If it happens, we say "yes". If not, we say "maybe"

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

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.  

Write a Python program stored in a file q1.py to play Rock-Paper-Scissors. In this game, two players count aloud to three, swinging their hand in a fist each time. When both players say three, the players throw one of three gestures: Rock beats scissors Scissors beats paper Paper beats rock Your task is to have a user play Rock-Paper-Scissors against a computer opponent that randomly picks a throw. You will ask the user how many points are required to win the game. The Rock-Paper-Scissors game is composed of rounds, where the winner of a round scores a single point. The user and computer play the game until the desired number of points to win the game is reached. Note: Within a round, if there is a tie (i.e., the user picks the same throw as the computer), prompt the user to throw again and generate a new throw for the computer. The computer and user continue throwing until there is a winner for the round.

Answers

Answer:

The program is as follows:

import random

print("Rock\nPaper\nScissors")

points = int(input("Points to win the game: "))

player_point = 0; computer_point = 0

while player_point != points and computer_point != points:

   computer = random.choice(['Rock', 'Paper', 'Scissors'])

   player = input('Choose: ')

   if player == computer:

       print('A tie - Both players chose '+player)

   elif (player.lower() == "Rock".lower() and computer.lower() == "Scissors".lower()) or (player.lower() == "Paper".lower() and computer.lower() == "Rock".lower()) or (player == "Scissors" and computer.lower() == "Paper".lower()):

       print('Player won! '+player +' beats '+computer)

       player_point+=1

   else:

       print('Computer won! '+computer+' beats '+player)

       computer_point+=1

print("Player:",player_point)

print("Computer:",computer_point)

Explanation:

This imports the random module

import random

This prints the three possible selections

print("Rock\nPaper\nScissors")

This gets input for the number of points to win

points = int(input("Points to win the game: "))

This initializes the player and the computer point to 0

player_point = 0; computer_point = 0

The following loop is repeated until the player or the computer gets to the winning point

while player_point != points and computer_point != points:

The computer makes selection

   computer = random.choice(['Rock', 'Paper', 'Scissors'])

The player enters his selection

   player = input('Choose: ')

If both selections are the same, then there is a tie

   if player == computer:

       print('A tie - Both players chose '+player)

If otherwise, further comparison is made

   elif (player.lower() == "Rock".lower() and computer.lower() == "Scissors".lower()) or (player.lower() == "Paper".lower() and computer.lower() == "Rock".lower()) or (player == "Scissors" and computer.lower() == "Paper".lower()):

If the player wins, then the player's point is incremented by 1

       print('Player won! '+player +' beats '+computer)

       player_point+=1

If the computer wins, then the computer's point is incremented by 1

   else:

       print('Computer won! '+computer+' beats '+player)

       computer_point+=1

At the end of the game, the player's and the computer's points are printed

print("Player:",player_point)

print("Computer:",computer_point)

The trackpad/touchpad on my laptop is acting unusual. When I click on something or move to an area, it jumps or moves to another area. What would be a good troubleshooting step to try and resolve this issue?

c. Refer caller to user guides

d. increase the brightness of the display

Answers

Answer:

My best answer would be, "b. Remove all possible contact points, and test again while ensuring only a single contact point"

This is because usually when the cursor jumps around without reason, it's caused by the user accidentally hitting the mouse touchpad on his or her laptop while typing. ... Similarly, know that just because you have an external mouse attached to your laptop, the built-in mousepad is not automatically disabled.
