Answer:
a. computers wait until the circuit is free before they send data.
Explanation:
In Computer science, controlled access (X-ON/X-OFF) is typically the opposite of contention.
Controlled access is mainly used by computer networks that are being managed by a host mainframe computer system. X-ON is ready to receive while X-OFF isn't ready to receive.
With contention, computers wait until the circuit is free before they send data. It generally prevents collision between computer systems.
Type two statements that use rand() to print 2 random integers between (and including) 100 and 149. End with a newline. Ex:
101
133
Note: For this activity, using one statement may yield different output (due to the compiler calling rand() in a different order). Use two statements for this activity. Also, srand() has already been called; do not call srand() again.
Code:
#include
#include // Enables use of rand()
#include // Enables use of time()
using namespace std;
int main() {
int seedVal = 0;
seedVal = 4;
srand(seedVal);
/* Your solution goes here */
return 0;
}
Answer:
Replace the comment with:
cout<<100 + rand() % 49<<endl;
cout<<100 + rand() % 49<<endl;
Explanation:
To generate random number from min to max, we make of the following syntax:
min + rand()%(max - min)
In this case:
[tex]min = 100[/tex]
[tex]max = 149[/tex]
So, we have:
100 + rand()%(149 - 100)
100 + rand()%49
To print the statements, make use of:
cout<<100 + rand() % 49<<endl;
cout<<100 + rand() % 49<<endl;

Answer:
Ok so RAM is Random-Access-Memory.
RAM can store data just like in a hard drive - hdd or solid state drive - ssd
but the thing is that ram is really fast and data is only stored when RAM chips get power. On power loss your all data will be lost too.
ROM thanslates to Read-Only-Memory - so data in ROM chips can't be modifyed computer can just read the data but not write.
Read-only memory is useful for storing software that is rarely changed during the life of the system, also known as firmware.
Have a great day.
Explanation:
Answer:
Ram which stands for random access memory, and Rom which stands for read only memory are both present in your computer. Ram is volatile memory that temporarily stores the files you are working on. Rom is non-volatile memory that permanently stores instructions for your computer
Write a Python program (rainfall.py) to collect data and calculate the average rainfall over a period of years. The program should first ask for the number of years. Then for each year, the program should ask twelve times, once for each month, for inches of rainfall for that month. At the end, , the program should display the number of months, the total inches of rainfall, and the average rainfall per month for the entire period.
Your program should contain two functions:
(1) rainfall(year): This function takes in a year (integer) as a parameter, and returns two values (totalMonths and totalRainfall). In this function, you need to use nested loop. The outer loop will iterate once for each year. The inner loop will iterate twelve times, once for each month. Each iteration of the inner loop will ask the user for inches (float) of rainfall for that month. After all iterations, the function should return the number of months (totalMonths) and the total inches of rainfall (totalRainfall). (Submit for 4 points)
(2) __main__: In the main, you do the following: (Submit for 6 points)
a. Prompt the user to input the number of years. Reprompt the user if the number of years is 0 or less. Hint: use a while loop.
b. Call rainfall(year) and pass to it the value entered above.
c. Calculate the average based on the returned values from rainfall function.
d. Display the number of months, the total inches of rainfall, and the average rainfall per month for the entire period.
Answer:
def rainfall(year):
totalMonths = totalRainfall = 0
for y in range(year):
for month in range(12):
rainfall = float(input(f"Enter inches of rainfall for month #{month+1}: "))
totalRainfall += rainfall
totalMonths = year * 12
return totalMonths, totalRainfall
def __main__():
while True:
year = int(input("Enter the number of years: "))
if year > 0:
break
numberOfMonths, totalRainfall = rainfall(year)
averageRainFall = totalRainfall / numberOfMonths
print(f"\nTotal number of months: {numberOfMonths}")
print(f"The total inches of rainfall: {totalRainfall}")
print(f"The average rainfall per month for the entire period: {averageRainFall}")
if __name__ == '__main__':
__main__()
Explanation:
Create a function named rainfall that takes year as a parameter
Inside the function:
Create a nested for loop. The outer loop iterates for each year (The range is from 0 to year-1) and the inner loop iterates for each month of that year (The range is from 0 to 11). Inside the inner loop, ask the user to enter the rainfall for that month. Add the rainfall to the totalRainfall (cumulative sum)
When the loops are done, calculate the totalMonths, multiply year by 12
Return the totalMonths and totalRainfall
Inside the main:
Create a while loop that asks user to enter the number of years while it is greater than 0
Call the rainfall function, passing the year as parameter. Set the numberOfMonths and totalRainfall using the rainfall function
Calculate the averageRainFall, divide totalRainfall by numberOfMonths
Print the results

I tried really hard to solve these. I hope this answers your questions. can you make me the brainliest, that all I ask since I answered it for you. Pleasure solving these. C:
Consider the regular expressions:
R1 = (01)* (0*1*) (10)
R2 = (101)* (01)*
R3 = (10) (01*)*(01)
R4 = 10(R2*)|R3
Recall that, for a list of regular expressions, the function getToken() returns the next token from the input that matches one of the regular expressions. If there is more than one match, the longest match is returned. If there is more than one longest match, the token with the longest match that appears first in the list is returned. If there is no match, ERROR is returned. If the function getToken() is called once on input 1000101, it will return:
a. R1
b. R2
c. R3
d. R4
e. ERROR
Answer:
c. R3
Explanation:
For R1;
there are 10 matches, after these 10 no matches occur again
for R2;
this also does not match more than 10 as we have in R1
for r3;
R3 has the longest match. Its matching can be done 1000101 times.
for r4;
The whole of r4 can be matched.
Error;
we cannot have an error because matches exist.
so in answer to this question we pick R3 as the solution because there are more than one longest march and the one returned in the list is that which appeared first. R3 came first
In this exercise we have to use computer knowledge to identify which is the correct sequence of code that best corresponds to the given question, in this way we have that the correct alternative is:
[tex]c. R3[/tex]
So analyzing the first alternative, we find;
For R1, there are 10 matches, after these 10 no matches occur again.
So analyzing the second alternative, we find;
For R2, this also does not match more than 10 as we have in R1
So analyzing the third alternative, we find;
R3 has the longest match. Its matching can be done 1000101 times.
So analyzing the fourth alternative, we find;
For R4, the whole of r4 can be matched.
So analyzing the fifth alternative, we find;
Error; we cannot have an error because matches exist.
So in answer to this question we pick R3 as the solution because there are more than one longest march and the one returned in the list is that which appeared first.

How should you schedule a meeting with someone in another time zone?
If you know what timezone they're in, try to work out what time in your own timezone your free, then tell the other person to do the same. Tell them what times in your timezone and the other can search up what the time is in their own timezone. If there is a specific time when you are both free, use that.
Ex:
You live in the U.S. but you have a meeting with someone in the U.K. You're only free at 4:00pm-6:00pm and they're only free from 10:00am-11:00am. 11:00am in England is 4:00pm in the U.S. so do at that time!

Modify the following code so that:
Make the pool start with a random number ([20, 30] inclusive) of coins.
Based on the number of the randomly generated coins at the beginning,
let the computer determine whether Player 1 or Player 2 will be the
winner based on the winning strategy (by printing out the winner).
After deciding the supposed winner and loser, let the computer play
out both of the roles. For the winner, the computer should be applying
the winning strategy; for the loser, the computer should generate a
random amount of coins while following all the rules of the game
Rules of the game:
a) The game starts with 22 coins in a common pool
b) The goal of the game is to take the last coin
c) Two players take turns removing 1, 2, or 3 coins from the pool
d) A player can NOT take more coins than remaining coins in the pool
e) After each turn, the judge announces how many coins remain in the
pool
f) When the last coin is taken, the judge announces the winner
turn=0 #turn=1 remaining coins-24 print(Take turns removing 1, 2, or 3 coins. ) print(You win if you take the last coin.)
Answer:
Explanation:
The following code makes all the necessary changes so that the game runs as requested in the question. The only change that was not made was making the number of coins random since that contradicts the first rule of the game that states that the game starts with 22 coins.
turn = 0
remaining_coins = 22
print("Take turns removing 1, 2, or 3 coins. ")
print("You win if you take the last coin.")
while remaining_coins > 0:
print("\nThere are", remaining_coins, "coins remaining.")
if turn % 2 == 0:
# Player1
taken_coins = int(input("Player 1: How many coins do you take?"))
turn += 1
else:
# Player2
taken_coins = int(input("Player 2: How many coins do you take?"))
turn += 1
if taken_coins < 1 or taken_coins > 3 or taken_coins > remaining_coins:
print("That's not a legal move. Try again. ")
print("\nThere are", remaining_coins, "coins remaining.")
if turn % 2 == 0:
# Player1
taken_coins = int(input("Player 1: How many coins do you take? "))
turn += 1
else:
# Player2
taken_coins = int(input("Player 2: How many coins do you take? "))
turn += 1
remaining_coins -= taken_coins
else:
remaining_coins -= taken_coins
if remaining_coins - taken_coins == 0:
print("No more coins left!")
if turn % 2 == 0:
print("Player 1 wins!")
print("Player 2 loses !")
else:
print("Player 2 wins!")
print("Player 1 loses!")
remaining_coins = remaining_coins - taken_coins

1. Add the following method to the Point class:
public double distance(Point other)
Returns the distance between the current Point object and the given other Point object. The distance between two points is equal to the square root of the sum of the squares of the differences of their x- and y-coordinates. In other words, the distance between two points (x1, y1) and (x2, y2) can be expressed as the square root of (x2 - x1)2 + (y2 - y1)2. Two points with the same (x, y) coordinates should return a distance of 0.0.
public class Point {
int x;
int y;
// your code goes here
}
2. Create a class called Name that represents a person's name. The class should have fields named firstName representing the person's first name, lastName representing their last name, and middleInitial representing their middle initial (a single character). Your class should contain only fields for now.
3. Add two new methods to the Name class:
public String getNormalOrder()
Returns the person's name in normal order, with the first name followed by the middle initial and last name. For example, if the first name is "John", the middle initial is 'Q', and the last name is "Public", this method returns "John Q. Public".
public String getReverseOrder()
Returns the person's name in reverse order, with the last name preceding the first name and middle initial. For example, if the first name is "John", the middle initial is 'Q', and the last name is "Public", this method returns "Public, John Q.".
4. Add the following method to the Point class:
public int quadrant()
Returns which quadrant of the x/y plane this Point object falls in. Quadrant 1 contains all points whose x and y values are both positive. Quadrant 2 contains all points with negative x but positive y. Quadrant 3 contains all points with negative x and y values. Quadrant 4 contains all points with positive x but negative y. If the point lies directly on the x and/or y axis, return 0.
public class Point {
private int x;
private int y;
// your code goes here
}
Answer:
Explanation:
The following code is written in Java and creates all of the methods that were requested in the question. There is no main method in any of these classes so they will have to be called from the main method and call one of the objects created method for the code to be tested. (I have tested it and it is working perfectly.)
class Point {
private int x, y;
public void Point(int x, int y) {
this.x = x;
this.y = y;
}
public double distance (Point other) {
double distance = Math.sqrt(Math.pow((other.x - this.x), 2) + Math.pow((other.y - this.y), 2));
return distance;
}
public int quadrant() {
if (this.x > 0 && this.y > 0) {
return 1;
} else if (this.x < 0 && this.y > 0) {
return 2;
} else if (this.x < 0 && this.y < 0) {
return 3;
} else if (this.x > 0 && this.y < 0) {
return 4;
} else {
return 0;
}
}
}
class Name {
String firstName, lastName;
char middleInitial;
public String getNormalOrder() {
String fullName = firstName + " " + middleInitial + " " + lastName;
return fullName;
}
public String getReverseOrder() {
String fullName = lastName + ", " + firstName + " " + middleInitial;
return fullName;
}
}

Assume the data link protocol used by NDAS has the following associated characteristics:
An 8-bit ASCII code is used. Each frame has a size (length) of 11936 bits. A half-duplex circuit with a speed of 1 million bits per second is used for transmission. There is a 30-millisecond turnaround time on the half-duplex circuit. Each frame contains 20 overhead (non-user-data) bytes. Assume that the probability of a frame requiring retransmission due to error in transmission is 1 percent. A millisecond is one-thousandth of a second. Also, 8 bits = 1 character = 1byte
Fill in the blanks
K= _________ bits per bytes
M=_________ bytes
C= _________ overhead bytes
Answer:
The transmission speed = 0.278 MB/s
Explanation:
K = 8 bits
M = 11936/8 bits = 1492 bits
transmission rate R = 1000000/ 8 = 125000 bps
overhead bytes C = 20
probability = 0.01
time T = 30 ms = 30 x10^-3 s
The data transmission speed formula = K(M-C)(1-p) / (M/R) + T
= 8( 1492 - 20)(0.99)/ (1492/125000) + 30 x10^-3
= 0.278 MB/s

Explanation:
Write a program that would determine the day number in a non-leap year. For example, in a non-leap year, the day number for Dec 31 is 365; for Jan 1 is 1, and for February 1 is 32. This program will ask the user to input day and month values. Then it will display the day number day number corresponding to the day and month values entered assuming a non-leap year. (See part II to this exercise below).
Answer:
In Python:
months = ["Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec"]
daymonths = [31,28,31,30,31,30,31,31,30,31,30,31]
day = int(input("Day: "))
month = input("Month: ")
ind = months.index(month)
numday = 0
for i in range(ind):
numday+=daymonths[i]
numday+=day
print(numday)
Explanation:
This initializes the months to a list
months = ["Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec"]
This initializes the corresponding days of each month to a list
daymonths = [31,28,31,30,31,30,31,31,30,31,30,31]
This gets the day from the user
day = int(input("Day: "))
This gets the month from the user
month = input("Month: ")
This gets the index of the month entered by the user
ind = months.index(month)
This initializes the sum of days to 0
numday = 0
This adds up the days of the months before the month entered by the user
for i in range(ind):
numday+=daymonths[i]
This adds the day number to the sum of the months
numday+=day
This prints the required number of days
print(numday)

Driving is expensive. Write a program with a car's miles/gallon and gas dollars/gallon (both doubles) as input, and output the gas cost for 20 miles, 75 miles, and 500 miles. Output each floating-point value with two digits after the decimal point, which can be achieved by executing cout << fixed << setprecision(2); once before all other cout statements.
Answer:
Explanation:
The following is written in C++ and asks the user for inputs in both miles/gallon and dollars/gallon and then calculates the gas cost for the requested mileages using the input values
#include <iostream>
#include <iomanip>
using namespace std;
int main () {
// distance in miles
float distance1 = 20.0, distance2 = 75.0, distance3 = 500.0;
float miles_gallon, dollars_gallon;
cout << "Enter cars miles/gallon: "; cin >> miles_gallon;
cout << "Enter cars dollars/gallon: "; cin >> dollars_gallon;
cout << "the gas cost for " << distance1 << " miles is " << fixed << setprecision(2) << (float) dollars_gallon * distance1 / miles_gallon << "$\n";
cout << "the gas cost for " << distance2 << " miles is " << fixed << setprecision(2) << (float) dollars_gallon * distance2 / miles_gallon << "$\n";
cout << "the gas cost for " << distance3 << " miles is " << fixed << setprecision(2) << (float) dollars_gallon * distance3 / miles_gallon << "$\n";
return 0;
}
