Explanation:

The pseudo-code that corresponds to the given assembly code is:

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"

This way, people wouldn't be able to access her computer easily, since it requires a code that only she would know. of course, there is the possibility that someone can just guess or hack into her computer, but that's why computers usually have you create a unique code that consists of uppercases, lowercases, numbers, special characters, etc which would be difficult to guess. it's a good protection for anyone who wants to safely keep their personal information from everyone else.

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 */

Genevieve is a student who attends classes at a campus downtown. She likes to study in the college's coffee shop, where she often accesses the Internet through the college's wireless network. Which network type is Genevieve using

Answers

Answer:

I'll let you make an educated guess off of this info! You always retain info better making an inference on a subject that you are having trouble with!

Explanation:

There are four types of wireless networks -- wireless local area networks, wireless metropolitan area networks, wireless personal area networks and wireless wide area networks -- each with its own function.

wireless local area network

A wireless local area network (WLAN) is a wireless distribution method for two or more devices. WLANs use high-frequency radio waves and often include an access point to the Internet. A WLAN allows users to move around the coverage area, often a home or small office, while maintaining a network connection.

wireless metropolitan area network

A metropolitan area network (MAN) is a computer network that connects computers within a metropolitan area, which could be a single large city, multiple cities and towns, or any given large area with multiple buildings. A MAN is larger than a local area network (LAN) but smaller than a wide area network (WAN).

wireless personal area network

A PAN provides data transmission among devices such as computers, smartphones, tablets and personal digital assistants. PANs can be used for communication among the personal devices themselves, or for connecting to a higher level network and the Internet where one master device takes up the role as gateway.

wireless wide area network

Wireless wide area network (WWAN), is a form of wireless network. ... WWAN connectivity allows a user with a laptop and a WWAN card to surf the web, check email, or connect to a virtual private network (VPN) from anywhere within the regional boundaries of cellular service.

I hope this helped!!

The network type Genevieve uses is a wireless local area network.

What is a wireless local area network?

A wireless local area network (WLAN) exists as a wireless distribution procedure for two or more devices. WLANs utilize high-frequency radio waves and often contain an access issue to the Internet. A WLAN permits users to move around the coverage area, often a house or small office, while preserving a network connection.

Therefore, the correct answer is option (a) LAN.

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)
