Answer:

ring network

Explanation:

In a ring network, the nodes are arranged in a circular pattern where each node is connected to two adjacent nodes. In this topology, any node can communicate with any other node via the intermediaries.

In comparison,

- in a star network every communication needs to pass through a central hub node

- in a bus, each node is connected to a shared linear communication bus.

- in a hierarchical network nodes are organized along a tree structure layout.

What is the significance of the scientific method?

Gnom [1K]

Hello there! The significance of the scientific method is that it ensures accuracy and it ensures that the experiment was done in the right order.

The scientific method is a widely accepted way of revising and rechecking the work of scientists to see if:

1. The answers match up

2. The experiment was performed correctly

3. The results are accurate

Through the scientific method, the probability is very high that things will not go wrong. The significance of this is that if the scientific method is not applied to an experiment, nobody knows the results. If nobody knows the results, there are many possible unintended consequences that could happen. Hope this helps!

) Perform error checking for the data point entries. If any of the following errors occurs, output the appropriate error message

emmainna [20.7K]

Answer:

In Python:

entry = input("Sentence: ")

while True:

if entry.count(",") == 0:

print("Error: No comma in string")

entry = input("Sentence: ")

elif entry.count(",") > 1:

print("Error: Too many comma in input")

entry = input("Sentence: ")

else:

ind = entry.index(',')+1

if entry[ind].isnumeric() == False:

print("Comma not followed by an integer")

entry = input("Sentence: ")

else:

break

print("Valid Input")

Explanation:

This prompts the user for a sentence

entry = input("Sentence: ")

The following loop is repeated until the user enters a valid entry

while True:

This is executed if the number of commas is 0

if entry.count(",") == 0:

print("Error: No comma in string")

entry = input("Sentence: ")

This is executed if the number of commas is more than 1

elif entry.count(",") > 1:

print("Error: Too many comma in input")

entry = input("Sentence: ")

This is executed if the number of commas is 1

else:

This calculates the next index after the comma

ind = entry.index(',')+1

This checks if the character after the comma is a number

if entry[ind].isnumeric() == False:

If it is not a number, the print statement is executed

print("Comma not followed by an integer")

entry = input("Sentence: ")

If otherwise, the loop is exited

else:

break

This prints valid input, when the user enters a valid string

print("Valid Input")

Note that: entry = input("Sentence: ") is used to get input

The variable sentence stores a string. Write code to determine how many words in sentence start and end with the same letter, in

irina [24]

Answer:

sentence = "hello wow a stores good"

same_letter_count = 0

sentence_list = sentence.split()

for s in sentence_list:

if s[0] == s[-1]:

same_letter_count += 1

print(same_letter_count)

Explanation:

*The code is in Python.

Initialize the sentence with a string

Initialize the same_letter_count as 0

Split the sentence using split method and set it to the sentence_list

Create a for loop that iterates through the sentence_list. If the first and last of the letters of a string are same, increment the same_letter_count by 1

When the loop is done, print the same_letter_count
