) 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

<em>    if entry.count(",") == 0:</em>

<em>        print("Error: No comma in string")</em>

<em>        entry = input("Sentence: ")</em>

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

<em>    elif entry.count(",") > 1:</em>

<em>        print("Error: Too many comma in input")</em>

<em>        entry = input("Sentence: ")</em>

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

<em>            print("Comma not followed by an integer")</em>

<em>            entry = input("Sentence: ")</em>

If otherwise, the loop is exited

<em>        else:</em>

<em>            break</em>

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

print("Valid Input")

Note that: entry = input("Sentence: ") <em>is used to get input</em>

Which is a connectionless protocol in the transport layer? What are the small chunks of data called?
xeze [42]

Answer:

User Datagram Protocol (UDP) , transport-layer segment.

Explanation:

The User Datagram Protocol is popularly known as UDP. It is defined as the communication protocol which is used across the internet for any time sensitive transmission like the DNS lookup or the video playback.

The UDP provides a unreliable and connectionless service to a invoking application.

The transport layers on sending side converts the application $\text{layer }$ messages which it $\text{receives}$ from the $\text{sending application process}$ into a transport layer segment called as the transport layer segments. This is achieved by breaking down the application messages into a smaller chunks and then adding the transport layer header into each chunk so as to create a transport layer segment.
