P36. In Section 3.5.4, we saw that TCP waits until it has received three duplicate ACKs before performing a fast retransmit. Why

do you think the TCP designers chose not to perform a fast retransmit after the first duplicate ACK for a segment is received?

Answer:

The Packets can be arrived out of an order from the Internet Protocol layer.  

So, whenever the out of an order packets would be received then, it would be generated the duplicate ACK's, if we perform the re-transmission after the first duplicate ACK would be lead the senders to introduced too many redundant packets in the networks.

Explanation:

  • All the bytes, in the Transmission Control Protocol connections, are the numbered, from the beginning at the randomly choose the initial sequence number (ISN).  
  • The SYN packets consumes the one sequence number, so the data will be actual and it begins at the ISN+1.  
  • The receivers ack's sequences the number x acknowledged the receipts of all the data bytes that is less than byte the number x.

When a field is declared static there will be ________. Group of answer choices two reference copies of the field for each metho
anygoal [31]

Answer: one field copy gets generated in memory

Explanation:

When a field is declared static,it will become common for entire class instances. Single copy of field that gets created for the particular class where numerous instances present in that class can use it by sharing .

  • Other options are incorrect because  two copy of reference does not gets created as it only supports single copy.
  • Copy of the field for every class is not generated by static field.All method and instances use  only one field copy for the whole class.
  • Thus the correct answer is creation of only one field copy in memory for static field.

Write an expression to print each price in stock_prices. Sample output with inputs: 34.62 76.30 85.05
Lana71 [14]

Answer:

Here is the Python program:

stock_prices = input().split() #to take input and splits it into a list

for price in stock_prices: #iterates through stock_prices

   print("$",price) #prints each value of stock_prices with a dollar sign

Explanation:

The program is well explained in the attached comments. I will explain the logic of the program with the help of an example:

Suppose the user enters the following input as stock_prices values

34.62 76.30 85.05

input() method is used to take input from user

split() method is used to split or break this input string and returns a list of strings as:

['34.62', '76.30', '85.05']    

Now the statement for price in stock_prices: iterates through each item of the list and print("$",price) prints each value of list with a dollar sign on the output screen as:

$ 34.62                                                                                                            

$ 76.30                                                                                                            

$ 85.05
