Globally, most cell phone carriers use GSM technology, a combination of time division and frequency multiplexing.
Why do you think this has become the multiplexing technology of choice for most carriers?
Why not code division, for example, which some major US cell phone carriers still use?

Answers

Answer 1

Answer:

The many reason why we still use Global System for Mobile communication is for the ability to transfer data and voice both at once. But others like Code Division does not have this feature.

Program

Hope you enjoyed your stay!

We're going to create a reservation making system to incorporate discounts for longer stays.

We’ll be getting the customer’s number of nights and we’ll also be getting the type of the room, which should be one of the following letters: D, Q, or K (for Double, Queen, or King). We’ll do that for two reservations.

To be able to advise the user on which reservation they should choose, we're going to have to make some calculations. First we'll need to determine the price per night. Double rooms go for $59.99 per night, Queen rooms are $69.99 per night, and King rooms are $79.99 per night.

Then we'll need to determine the discount. For every night over 2, a 15% discount should be applied. For example, if the stay is for 4 nights, then a 30% discount would be applied to the overall price.

Finally, we need to let the user know which stay is the cheapest or if they're the same cost.
Input:

The user should be prompted for a set of two values which represent the number of nights and the room type for the first reservation. The number of nights should be a whole number. The room type should be a single letter. The user should enter both values on one line, separated by spaces. The user should then be prompted for the remaining reservation.

Example (the highlighted part is what the program displays and the italicized part is the user input): Reservation 1 (#nights type): 3 D
The example executable:

An example executable is provided in this repository. You should be able to run it from your project folder. If you encounter a “permission denied” error when attempting to run the executable, type chmod u+x hotelsExecutable into the terminal and try running the executable again.
Requirements

main()
Functionality: The main function should prompt the user for two reservations. The room rate for each room for each reservation must be determined. Then the reservation total for each reservation can be calculated. A message should be displayed advising the user on which reservation is the better deal.

In addition to the main functions, your program should have 2 more functions:

getRoomRate()
Input Parameters: room type
Returned Output: room rate
Functionality: Given the type of room, this function should return the appropriate room rate.

calcReservation()
Input Parameters: room rate, number of nights
Returned Output: total reservation price
Functionality: Given the room rate and number of nights, this function should return the total reservation price with any applicable discount applied.

Assume that a, b, and c have been declared and initialized with int values. The expression

!(a > b || b <= c)
is equivalent to which of the following?

a. a > b && b <= c
b. a <= b || b > c
c. a <= b && b > c
d. a < b || b >= c
e. a < b && b >= c

Answers

Answer:

Option c (a <= b && b > c) and Option e (a < b && b >= c) is the correct answer.

Explanation:

According to the question, the given expression is:

⇒ !(a > b || b <= c)

There will be some changes occur between the values such as:

! = It becomes normal> = It becomes <|| = It becomes &&

So that the expression will be:

⇒ a <= b && b > c

and

⇒ a < b && b >= c

Other choices are not connected to the expression or the rules. So the above two alternatives are the correct ones.

4. Interaction between seller and buyer is called___.

A. Demanding
B. Marketing
C. Transactions
D. Oppurtunity​

Answers

Answer:

C. Transactions.

Explanation:

A transaction can be defined as a business process which typically involves the interchange of goods, financial assets, services and money between a seller and a buyer.

This ultimately implies that, any interaction between a seller and a buyer is called transactions.

For example, when a buyer (consumer) pays $5000 to purchase a brand new automobile from XYZ automobile and retail stores, this is referred to as a transaction.

Hence, a transaction is considered to have happened when it's measurable in terms of an amount of money (price) set by the seller.

Price can be defined as the amount of money that is required to be paid by a buyer (customer) to a seller (producer) in order to acquire goods and services. Thus, it refers to the amount of money a customer or consumer buying goods and services are willing to pay for the goods and services being offered. Also, the price of goods and services are primarily being set by the seller or service provider.

}
The deposit method is intended to increase the account balance by the deposit amount and then return the updated balance. Which of the following code segments should replace /* missing code */ so that the deposit method will work as intended?
a.
amount = balance + amount;
return amount;
b.
balance = amount;
return amount;
c.
balance = amount;
return balance;
d.
balance = amount;, , return balance;,
balance = balance + amount;
return amount;
e.
balance = balance + amount;
return balance;

Answers

Answer:

e.

balance = balance + amount;

return balance;

Explanation:

Required

Code to update account balance and return the updated balance

The code that does this task is (e).

Assume the following:

[tex]balance = 5000; amount = 2000;[/tex]

So, code (e) is as follows:

balance = balance + amount; [tex]\to[/tex]

[tex]balance = 5000 + 2000[/tex] [tex]\to[/tex]

[tex]balance = 7000[/tex]

Here, the updated value of balance is 7000

So: return balance

will return 7000 as the updated account balance

Answer:

Virus & threat protection.

Explanation:

Monitor threats to your device, run scans, and get updates to help detect the latest threats.

One Microsoft Windows security feature that can help protect data is BitLocker Drive Encryption.

BitLocker is a full-disk encryption feature available in certain editions of Microsoft Windows, such as Windows 10 Pro and Enterprise. It provides protection for data stored on the system's hard drives or other storage devices.

By encrypting the entire drive, BitLocker helps safeguard the data against unauthorized access or theft, even if the physical drive is removed from the device. It uses strong encryption algorithms to convert the data into an unreadable format, ensuring that only authorized users with the appropriate encryption key or password can access and decrypt the data.

BitLocker also provides additional security features, such as pre-boot authentication, which requires users to enter a password or use a USB key to unlock the drive before the operating system loads. This prevents unauthorized users from accessing the encrypted data, even if they have physical access to the device.

Overall, BitLocker Drive Encryption is a powerful security feature in Microsoft Windows that can effectively protect data by encrypting entire drives and adding layers of authentication and protection against unauthorized access.

5.19 LAB: Output values in a list below a user defined amount
Write a program that first gets a list of integers from input. The input begins with an integer indicating the number of integers that follow. Then, get the last value from the input, which indicates a threshold. Output all integers less than or equal to that last threshold value.

Ex: If the input is:

5
50
60
140
200
75
100
the output is:

50,60,75,
The 5 indicates that there are five integers in the list, namely 50, 60, 140, 200, and 75. The 100 indicates that the program should output all integers less than or equal to 100, so the program outputs 50, 60, and 75.

For coding simplicity, follow every output value by a comma, including the last one.

Such functionality is common on sites like Amazon, where a user can filter results.

Answers

Answer:

The program in Python is as follows:

n = int(input())

myList = []

for i in range(n):

   num = int(input())

   myList.append(num)

threshold = int(input())    

for i in myList:

   if i<= threshold:

       print(i,end=", ")

Explanation:

This gets the number of inputs

n = int(input())

This creates an empty list

myList = []

This iterates through the number of inputs

for i in range(n):

For each iteration, this gets the input

   num = int(input())

And appends the input to the list

   myList.append(num)

This gets the threshold after the loop ends

threshold = int(input())    

This iterates through the list

for i in myList:

Compare every element of the list to the threshold

   if i<= threshold:

Print smaller or equal elements

       print(i,end=", ")

The Python program below gets a list of integers, then filters that list based on a threshold value:

########################################################

# initialize the integer and output lists

integer_list = [ ]

output_list = [ ]

# first enter the number of integers that will follow

# and append it to integer list

qty = int(input("Enter the number of integers to follow: "))

integer_list.append(qty)

# next enter the number of integers and append them to integer list

for i in range(0, qty):

   num = int(input("Enter an integer: "))

   integer_list.append(num)

# finally enter the threshold value to be used to filter the integers

threshold = int(input("Enter the threshold value: "))

integer_list.append(threshold)

# filter the integers

for num in integer_list:

   if num <= integer_list[-1]:

       output_list.append(num)

# display the result

print("The values from { } that are less than or equal to { } are

   { }".format(integer_list[1:-1], integer_list[-1], output_list))

########################################################

The program first asks the user to enter the following:

The number of integers to be checkedThe integers themselvesThe threshold value to be used for filtering

The program next iterates over the integer list and filters the integers from index 1 to index -1(exclusive, since this is the threshold value) based on the element at index -1(the last element, the threshold value).

Each element that satisfies the filtering criterion (e <= threshold) is added to the output list and printed out later.

Answer:

The best method to use to sort the array in descending order is:

e. Il only

Explanation:

The Merge Sort is similar to the Insertion Sort but, it is better with its sorting versatility.  It repeatedly breaks down a list into several sub-lists until each sub-list consists of a single element and then, merging the sub-lists in a manner that results in a sorted list.  The Merge Sort has been described as a "divide and conquer" technique because of how it splits a list into equal halves before combining them into a sorted whole.

(Note: In this and all other problems, we are assuming that 100% of the food calories that are eaten are absorbed and used by the body. This is actually not true. A person's "metabolic efficiency" is the percentage of calories eaten that are actually used; the rest are eliminated by the body. Metabolic efficiency varies considerably from person to person.)Express your answer in meters. Kenna's bedroom is 12 feet long by 8 feet long.
