Most networking media send data using _____ in which data is represented by only two discrete states: 0s and 1s.A. digital signals

B. contiguous signals

C. ramp signals

D. exponential signals

Answers

Answer 1
Answer:

Answer: A) Digital signals

Explanation:

  • Digital signal is a signal that helps in describing about the data in sequential manner in form discrete bands or binary values.
  • The electrical signal containing data is converted into bits that can be represented through two digital values i.e. 0s and 1s.
  • Other options are incorrect because contiguous signal is regular adjacent signal. Ramp signal is represented as increment in magnitude with time
  • Exponential signal is based on sine and cosine signal that is two real time signal.
  • Thus, the correct option is option(A).
Answer 2
Answer:

Answer:

i think digital signals

Explanation:

A digital signal is a signal that is being used to represent data as a sequence of discrete values; at any given time it can only take on one of a finite number of values.[1][2][3] This contrasts with an analog signal, which represents continuous values; at any given time it represents a real number within a continuous range of values.

Your app needs to store the following information. For each type of information, decide whether you would use an array or a variable to store it:(a) All the messages a user has sent(b) The highest score a user has ever reached on the app(c) A username and password to unlock the app

Answers

Answer:

Array: (a) All the messages a user has sent.

Variable: (b) The highest score a use has reached on the app. (c) A username and password to unlock the app.

Explanation:

An array generally has more than one value whereas a variable can only contain a single value at any particular point in time. In addition, a variable has a limit whereas an array does not have any maximum limit. Therefore, it can be concluded that option (a) will be stored as an array while options (b) and (c) will be stored as variables.

Failing to include a complete ____ on each side of an && operator in an if statement is a common error in Java programming.a.

c.
variable

d.
Boolean expression

Answers

Answer:

Boolean expression

Explanation:

The operator '&&' is called AND operator. it provide the output base on the Boolean value on each side of AND operator.

it has four possible values:

First Boolean is TRUE and Boolean is TRUE, then result will be TRUE.

First Boolean is TRUE and Boolean is FALSE, then result will be FALSE.

First Boolean is FALSE and Boolean is TRUE, then result will be FALSE.

First Boolean is FALSE and Boolean is FALSE, then result will be FALSE.

Therefore, the correct option is Boolean expression.

Explanation:

Write a program to calculate how much to tip a waiter person based on the quality of service. The script file should ask for the amount of the check and whether the service was good, fair or poor. If the service was good, the tip should be 20%. If the service was fair, the tip should be 15%. If the service was poor, the tip should be 5%. The program should display the tip and the total of the check including the tip.

Answers

Answer:

Since Python is a scripting language, here is code in python.

#prompt user to give check

amount=float(input("Please Enter the check:"))

#prompt user to give service

service=input("Please Enter the service (good, fair or poor):")

# calculate tip on the basis of service

if service =="good":

   tip=amount*0.2

elif service=="fair":

   tip=amount*0.15

elif service=="poor":

   tip=amount*0.05

#calculate total

total=amount+tip

#print tip

print("tip is equal to : {} ".format(tip))

#print total

print("total of the check is : {} ".format(total))

Explanation:

Prompt user to give check and service input.After taking the input from user, based on the service tip will be calculated. if service is "good" then tip will be 20% of the check, tip will be 15% if service is "fair" and tip will be 5% if service is "poor".

Output:

Please Enter the check:125                                                                                                

Please Enter the service (good, fair or poor):good                                                                        

tip is equal to : 25.0                                                                                                    

total of the check is : 150.0

CHALLENGE 7.1.1: Initialize a list. ACTIVITY Initialize the list short.names with strings 'Gus', Bob, and 'Ann'. Sample output for the given program Gus Bob Ann 1 short_names- Your solution goes here 2 # print names 4 print(short_names[0]) 5 print(short names [11) 6 print(short_names[2])

Answers

Answer:

short_names = ["Gus", "Bob", "Ann"]

print(short_names[0])

print(short_names[1])

print(short_names[2])

Explanation:

There are some typos in your code. In addition to the missing part of the code, I corrected the typos.

First of all, initialize the list called short_names. The list starts with "[" and ends with "]". Between those, there are must be the names (Since each name is a string, they must be written between "" and there must be a semicolon between each name)

Then, you can print each name by writing the name of the list and the index of the names between brackets (Index implies the position of the element and it starts with 0)
