Answer:
A four-way handshake has occurred.
Explanation:
TCP or transmission control protocol is a packet-oriented protocol because all lost packets are retransmitted if not received and acknowledged by the destination host.
A four-way handshake connection is established between the server and the client, this allows for connection initiation, negotiation, and termination. The packets sent across are never lost as received packets are acknowledged by the client by sending an ACK to the transmitting server.
The TCP is a main protocol for the internet protocol suite and initiates the network implementation, by complementing the IP. It connection-oriented protocol.
The device that has connected with the TCP undergo a four-way handshake, which is the process of exchanging four messages between the access point. This allows for the generation of encryption keys that are sued to encrypt the data.Learn more about the Transmission Control Protocol.

The method longestStreak is intended to determine the longest substring of consecutive identical characters in the parameter str and print the result.
For example, the call longestStreak("CCAAAAATTT!") should print the result "A 5" because the longest substring of consecutive identical characters is "AAAAA".
Complete the method below. Your implementation should conform to the example above.
public static void longestStreak(String str)
public class JavaApplication72 {
public static void longestStreak(String str){
char prevC = '_';
String largest = "";
String txt = "";
for (int i = 0; i < str.length(); i++){
char c = str.charAt(i);
if (c != prevC){
txt = "";
}
txt += c;
if (txt.length() > largest.length()){
largest = txt;
}
prevC = c;
}
System.out.println(largest.charAt(0)+" "+largest.length());
}
public static void main(String[] args) {
longestStreak("CCAAAAATTT!");
}
}
A Method in java is a block of named statements, that can be executed by simply calling it.
The method longestStreak in Java is as follows where comments are used to explain each line is as follows:
public static void longestStreak(String str){
//This initializes the initial character to an empty character
char previousChar = ' ';
//This initializes the current and the longest streak to an empty string
String largestStreak = "", currentStreak = "";
//This iterates through the string
for (int i = 0; i < str.length(); i++){
//This checks if the current character and the previous character are not the same
if (str.charAt(i) != previousChar){
//If yes, the streak is reset
currentStreak = "";
}
//The streak continues here
currentStreak += str.charAt(i);
//This checks the length of the longest streak
if (currentStreak.length() > largestStreak.length()){
largestStreak = currentStreak;
}
//This sets the previous character to the current character
previousChar = str.charAt(i);
}
//This prints the longest streak and its length
System.out.println(largestStreak.charAt(0)+" "+largestStreak.length());
}
At the end of the method, the longest streak and its length, are printed.

1. Describe the general characteristics of a program that would exhibit very high amounts of temporal locality but very little spatial locality with regard to data accesses, and give an illustrative example.2. Describe the general characteristics of a program that would exhibit very little temporal and spatial locality with regards to data accesses.3. Describe the general characteristics of a program that would exhibit very little temporal locality but very high amounts of spatial locality with regards to data accesses.
Answer:
A program with high temporal locality with regards to data access is the tight or continuous use of a loop and a memory in chunks, while low temporal locality is little or no reuse of loop and memory. The high amount of spatial locality is the little or no reuse of branches in data access, while low spatial locality is the high reuse of branches in the code.
Explanation:
Computer program requires for a written source code to retrieve and save data to memory. A high temporal locality uses loops to continuously access memory. For speed, all the read instructions are done and the data is cached in an iterable data structure.
Spatial locality is the degree of the use of branches in a code. if more branches are used in the program, then the program is said to have low spatial locality, if little or no branches are used, then the code has high spatial locality.

Objective: Write a program that will read and parse data from a file, then make use of lists to solve a problem.
Problem: Using python, write a program that will compute the maximum possible profit for a stock trade using historical data on a selection of companies. We would like to find the maximum possible profit that we could have gained, if we had made an ideal investment (if we ever finish that time machine). We must determine the largest increase in value from the purchase date to the sell date, using historical information. We will use the daily low price to purchase and the daily high price to sell a stock. For this assignment, we will use actual freelyavailable stock data stored in .CSV (comma separated values) format from Yahoo finance. A significant part of the exercise is learning to read and parse data from files and to format output.
1. Request the name for the input data file to be used to determine the results. You will have to run your program on all of the data sets to generate the required results. If the program does not exist, print a warning message and allow the user to try again.
2. Read in all the data from the requested file and parse the data; extracting the useful bits into one or more lists.
3. Use the data to determine the largest gain possible in a stock price by comparing Low values as the purchase price and High values as the sale price.
4. Report for each stock symbol (AAPL, AMZN, GOOG, MSFT, and TSLA) the purchase and sale days, the purchase and sale prices, profit per share, and the ratio of the change in value. Enter these results as submission comments in Blackboard.
5. Continue to request file names until the user enters a blank name (empty string), then exit the program.
6. Use good functional style and suitable variable names.
7. In the submission comment, answer the question: If you could travel back in time and invest in one of the five stocks listed, which stock would you pick?
Note: Assume that you must keep stocks for at least one day, no buying and selling on the same day. The data files contain more data than is needed, be sure to use the correct values. Be sure to move the data files into the same folder as your code so that your program can find the data files.

while csvfile:
file = open(csvfile, 'r')
data = csv.DictReader(file)
profit_list = [row['High'] - row['Low'] for row in data]
print(f"The maximum profit is: {max(profit_list)}")
for row in data:
print(f"Buy on {row['Data']} at the price of {row['Low']}")
print(f"Sell on {row['Data']} at the price of {row['High']}")
print(f"Change in value ratio: {row['High']/row['Low']}")
csvfile = input("Enter filename: ")
stock_prof()
Explanation:
Assuming the CSV file is in the same directory as the python script, the user inputs the file name and uses the CSV DictReader method to read the file as an ordered dictionary, then the maximum profit is printed as well as the date to buy and sell and the change in value ratio.
Consider the following class which is used to represent a polygon consisting of an arbitrary number of (x, y) points:
class Polygon :
def __init__(self) :
self._x_points = []
self._y_points = []
Answer:
The init method of the Polygon class defines two attributes 'x' and 'y' which are both lists. To add points to the lists x and y, define the add_point method;
def add_point(self, x, y) :
self._x_points.append(x)
self._y_points.append(y)
Explanation:
A class is a blueprint of a data structure. It contains the attributes and methods of the data structure type. Attributes are features of a data structure defined as variables that can be either a class attribute or an attribute of the instance of the class object. A method is just a function defined in a class.
The add_point method in the polygon class accepts two parameters and appends the values to the x and y lists defined in the init method.

Who is least likely to be treated with somatropin?
A 3-year-old cow on a dairy farm
A 4-year-old girl with an XO genetic genotype
A 44-year-old boy with chronic renal failure and gronih deficiency
A 10-year-old boy with polydipsia and polyuria
A 10-year-old boy with polydipsia and polyuria would likely not be treated with somatropin.
This is because somatropin is often used for growth issues and even short bowel syndrome, but from what I could find, nothing about polydipsia or polyuria.
A 3-year-old cow on a dairy farm could need somatropin, specifically Bovine Somatotropin (bST) to increase milk production or fix growth issues
A 4-year-old girl with an XO genetic genotype would get somatropin because it is used to treat Turner syndrome (Same as XO genetic genotype)
A 44-year-old boy with chronic renal failure and growth deficiency would get somatropin because it is used to treat growth issues even in adults and chronic renal failure

Assume a system has a TLB hit ratio of 90%. It requires 15 nanoseconds to access the TLB, and 85 nanoseconds to access main memory. What is the effective memory access time in nanoseconds for this system?
Answer:
310 ns
Explanation:
Given that
TLB hit ratio = 90%
TLB hit ratio = 90/100
TLB hit ratio = 0.9
Time needed to access TLB = 15 ns
Time needed to access main Memory = 85 ns
Effective memory access time = ?.
The formula for finding the effective memory access time is given by
The effective memory access time = [TLB Hit ratio (main memory access time + required time to access TLB) + [2 * (main memory access time + required time to access TLB)] * (2 - TLB hit ratio)]
On substituting the values given in the question to the equation, we have
The effective memory access time = [0.9 (85 + 15) + [2 * (85 + 15)] * (2 - 0.90)]
The effective memory access time =
[(0.9 * 100) + (2 * 100) * 1.1]
The effective memory access time =
(90 + (200 * 1.1))
The effective memory access time =
90 + 220
The effective memory access time =
310 ns
