State three reasons why users attach speakers to their computer​

Answer:

The change in complex systems can be explained according to the relationship of the environment where the system is implemented.

The system environment is dynamic, which consequently leads to adaptation to the system, which generates new requirements inherent to changes in business objectives and policies. Therefore, changing systems is necessary for tuning and usefulness so that the system correctly supports business requirements.

An example is the registration of the justification of the requirements, which is a process activity that supports changes in the system so that the reason for including a requirement is understood, which helps in future changes

Below is the required program of Python.

Program:

# Array name will be "N".

# Start program

# Defining a function and taking input array

def printIt(ar):

# Using for loop to scan the rows as well as columns of array

 for row in range(len(ar)):

     for col in range(len(ar[0])):

# Printing the element of array

         print(ar[row][col], end=" ")

     print("")

# Passing the array N

N=[]

# Again using the loop

for r in range(4):

 N.append([])

# Loop to control rows

for r in range(len(N)):

 value=1

# Loop to control columns

 for c in range(5):

     N[r].append(value)

     value=value + 1

# Calling the function

printIt(N)

print("")

newValue=1

# Value in row and column

for r in range (len(N)):

 for c in range(len(N[0])):

# Assigning the values to the array

     N[r][c] = newValue

 newValue = newValue + 1

# Printing the array

# End program

Answer:

Explanation:

The following program asks the user to enter the precinct number and then loops to add votes until no more votes need to be added. Then it breaks the loop and creates a file called results to save all of the results for that precinct.

precinct = input("Enter Precinct Number: ")

option1 = 0

option2 = 0

while True:

   choice = input("Enter your vote 1 or 2: ")

   if int(choice) == 1:

       option1 += 1

   else:

       option2 += 1

   endVote = input("Vote again y/n")

   if endVote.lower() != 'y':

       break

f = open("results.txt", "w")

f.write("Precinct " + precinct + ": \nOption 1: " + str(option1) + "\nOption 2: " + str(option2))

Answer:

Volume: Volume refers to the sheer size of the ever-exploding data of the computing world. It raises the question about the quantity of data.

Velocity: Velocity refers to the processing speed. It raises the question of at what speed the data is processed.

Variety: Variety refers to the types of data.

Explanation:

Answer:

The program in python is as follows:

original = []

inp = int(input(": "))

while inp>=0:

   if inp<=2000000000:

       original.append(inp)

   inp = int(input(": "))

newlist = []

for i in original:

if i not in newlist:

 newlist.append(i)

newlist.sort()

for i in newlist:

   print(i)

Explanation:

This initializes the original list

original = []

This gets input for the list

inp = int(input(": "))

The following loop is repeated while input is not negative

while inp>=0:

This ensures that only inputs from 0 and 2000000000 enters the list

   if inp<=2000000000:

       original.append(inp)

Prompt the user for another input

   inp = int(input(": "))

This initializes a newlist

newlist = []

Iterates through the original list

for i in original:

Check for duplicate

if i not in newlist:

Each number is entered to the new list, without duplicate

 newlist.append(i)

This sorts the new list in ascending order

newlist.sort()

This prints the list item one per line

for i in newlist:

   print(i)

Answer:

In Python:

prices = []

pounds = []

print("Enter 0 to stop input")

for i in range(10):

   pr = float(input("P rice: "+str(i+1)+": "))

   pd = float(input("Pound: "+str(i+1)+": "))

   if pr != 0 and pd != 0:

       prices.append(pr)

       pounds.append(pd)

   else:

       break

amount = 0

for i in range(len(pounds)):

   amount+= (pounds[i]*prices[i])

print("Amount: $",amount)

Explanation:

These initialize the prices and pounds lists

prices = []

pounds = []

This prompts the user to enter up to 10 items of press 0 to quit

print("Enter 0 to stop input")

This iterates through all inputs

for i in range(10):

This gets the price of each item

   pr = float(input("P rice: "+str(i+1)+": "))

This gets the pound of each item

   pd = float(input("Pound: "+str(i+1)+": "))

If price and pound are not 0

   if pr != 0 and pd != 0:

The inputs are appended to their respective lists

       prices.append(pr)

       pounds.append(pd)

If otherwise, the loop is exited

   else:

       break

This initializes total to 0

amount = 0

This iterates through all inputs

for i in range(len(pounds)):

This multiplies each pound and each price and sum them up

   amount+= (pounds[i]*prices[i])

The total is then printed

print("Amount: $",amount)

Answer:

A. a brochure distributed to many people.

D. a blog.

Explanation:

Communication can be defined as a process which typically involves the transfer of information from one person (sender) to another (recipient), through the use of semiotics, symbols and signs that are mutually understood by both parties.

Generally, the linear model of communication comprises of four (4) main components and these are;

1. Sender (S): this is typically the source of information (message) or the originator of a message that is being sent to a receiver. Thus, they are simply the producer of a message.

2. Channel (C): this is the medium used by the sender for the dissemination or transmission of the message to the recipient. For example, telephone, television, radio, newspapers, billboards etc.

3. Message (M): this is the information or data that is being sent to a recipient by a sender. It could be in the form of a video, audio, text message etc.

4. Receiver (R): this is typically the destination of information (message) or the recipient of a message that is being sent from a sender.

Hence, the following are forms of media (communication channel);

I. A brochure distributed to many people. It comprises of printed textual informations used mainly for promotional purposes.

II. A blog. It is an online website that contains both textual and multimedia messages, especially as a news platform.
