Steps in the Connection-Oriented session or "The Three-Way Handshake" of the Transport Layer
Answers
The steps in the Connection-Oriented session, also known as "The Three-Way Handshake" in the Transport Layer.
The three key terms in this process are: SYN (Synchronize), ACK (Acknowledge), and FIN (Finish).
1. SYN: The initiating device (client) sends a TCP packet with the SYN (Synchronize) flag set, indicating the client's desire to establish a connection with the server.
The client also provides its initial sequence number.
2. SYN-ACK: Upon receiving the SYN packet, the server sends a TCP packet back to the client with the SYN and ACK flags set.
This SYN-ACK packet indicates that the server acknowledges the client's request and is willing to establish a connection.
The server also provides its own initial sequence number.
3. ACK: The client receives the SYN-ACK packet from the server and sends a final TCP packet with the ACK flag set, acknowledging the server's response.
This packet confirms that both the client and server are ready to communicate and have successfully established a connection.
Once the three-way handshake is complete, the connection-oriented session begins, and data can be transmitted between the client and server.
The Transport Layer ensures reliable data transfer and error correction during the session.
When the session is finished, a similar process using the FIN flag is used to terminate the connection.

What validation type would you use to check that numbers fell within a certain range? a) range check b)presence check c)check digit d)consistency check
Answers
Answer:
a) range check
Explanation:
Validation can be defined as an automatic computer check that is designed to ensure any data entered is sensible, consistent, feasible and reasonable.
Basically, there are five (5) main validation methods and these includes;
I. Presence check: checks that the user enters (inputs) data into the field. It ensures a field isn't accidentally left blank.
II. Length check: checks that the data entered isn't too short or too long. It ensures that the data meets the minimum characters.
III. Type check: checks that the data entered is in the right format. For example, string, integer, float, etc.
IV. Check digit: checks that the digit entered is acceptable and consistent with the rest of the digits.
V. Range check: checks that the data entered is between the accepted lower (minimum) and upper (maximum) level.
Hence, range check is a validation type you would use to check that numbers fell within a certain range.
For example, 0 < x > 1000 is a range check.

How does the average function work? what list does it use? how is it traversed using a for loop?
Answers
The average function works by calculating the average of the numbers in a given list. It takes a list as an argument and returns the average value of the numbers in that list.
The list can be any type of iterable object such as a list, tuple, or dictionary, but it must contain numerical values. To calculate the average, the function first adds up all the numbers In the list and then divides the total by the number of values in the list.
Here's an example of how to use the average function:
pythonnumbers = [1, 2, 3, 4, 5]
avg = sum(numbers) / len(numbers)
print("The average is:", avg)
This code will print out the average of the numbers in the list numbers. The sum() function adds up all the numbers in the list, and the len() function returns the number of values in the list.
The average function can be traversed using a for loop by iterating over each value in the list and adding them up. Here's an example:
pythonnumbers = [1, 2, 3, 4, 5]
total = 0 for num in numbers:
total += numavg = total / len(numbers)
print("The average is:", avg)
In this code, we first initialize a variable total to 0, and then we loop through each value in the list numbers. Inside the loop, we add each value to the total variable. Once the loop is finished, we divide total by the length of the list to get the average value. Finally, we print out the average value using the print() function.

Problem 1 (name this Lab5_Problem1) using java
This problem will have you construct two conversion charts with a starting and ending boundary for each one. Think of things you've seen before, like square root tables or tip charts. The techniques you'll apply here are how those things are constructed.
The particular charts you'll code is based on the first letter of your last name. You only need to code two for lab credit. If you need more practice, do them on your own.
⦁ There are eight chart types, depending on your last name. It's been broken up statistically based on census data
⦁ A, B, C: do Chart 1 using a while loop, Chart 8 using a for loop
⦁ D, E, F: do Chart 2 using a while loop, Chart 7 using a for loop
⦁ G, H, I: do Chart 3 using a while loop, Chart 6 using a for loop
⦁ J, K, L: do Chart 4 using a while loop, Chart 5 using a for loop
⦁ M, N: do Chart 5 using a while loop, Chart 4 using a for loop
⦁ O, P, Q: do Chart 6 using a while loop, Chart 3 using a for loop
⦁ R, S, T: do Chart 7 using a while loop, Chart 2 using a for loop
⦁ U through Z: do Chart 8 using a while loop, Chart 1 using a for loop
⦁ Use a main() method plus two additional methods, one using a while loop, the other based on a for loop. Code your solution in the chart order above.
⦁ Name your two methods with appropriate names based on the chart type. Follow class naming standards: fv + a description of what the method does.
⦁ Refer to the flow chart on void() methods for guidance; naming standards are at the bottom.
⦁ Pass the lower and upper boundaries for the chart as arguments from main(). Examine the samples and you'll see each one's starting and ending boundary. Your Method Flow Diagram shows how to set up the method call. For experience, you'll pass the arguments two different ways, one for each of your chart:
⦁ For your first chart assignment, simply pass both arguments to the method as numeric literals in the argument list (kind of like hard-coding them).
⦁ For your second assigned chart, declare variables in main()for each argument, assign their values in another set of statements, and finally include the variables in the argument list for the method call.
⦁ Receive the two arguments in your method header as parameters. Remember, use standard variable names like you've done all along but add a "p" prefix to parameters so you can easily trace them later. The parameters will inherit the values passed to them from main() and use them to govern the start and end of your chart. See the Method Flow Diagram for parameter naming rules.
⦁ Follow the DITM steps regardless of whether you're doing a while or for chart, but remember, your initial and terminal values are the boundaries of the chart. You only need one additional variable since the parameters provide the other pieces of information.
⦁ Run the program. If all goes well, your output should appear like the sample.
The Problems (Based on Your Last Name)
Display the output the output to the number of decimal places shown, and include leading and trailing 0s.
⦁ A Fahrenheit to Celsius conversion chart. Range temperature in degrees F: 0 F to 212 F in one-degree increments.
0.00 degrees F = -17.78 degrees C
...
212.00 degrees F = 100.00 degrees C
⦁ A liquid measure conversion chart that shows ounces and the corresponding number of milliliters. Range of ounces: 1 to 20, in 0.5 ounce increments.
1.00 ounce = 29.57 milliliters
...
20.00 ounces = 295.74 milliliters
⦁ A multiplication table for the "7" series. The multiplicand will always remain a 7; the multiplier range: 1 to 10.
1 x 7 = 7
2 x 7 = 14
3 x 7 = 21
...
10 x 7 = 70
⦁ A statute mile conversion chart that displays the miles and the corresponding number of feet. Range of statute miles: 1 to 20 miles in increments of 1 mile.
1.00 miles = 5280.00 feet
...
10.00 miles = 52800.00 feet
⦁ A gas to oil conversion chart that shows the amount of oil needed to achieve a 50:1 ratio. Range for gas: 1 to 10 gallons in 0.5 gallon increments.
1 gallon of gas: 2.56 ounces oil
...
10 gallons of gas: 25.60 ounces oil
⦁ A square root table that displays the square root for each given value. Range of values: 1 to 100, in increments of 1.
Square root of 1 = 1.00
...
Square root of 100 = 10.00
Answers
Based on your last name, you have been assigned to create two conversion charts using Java.
How to write the code

1. Fahrenheit to Celsius Conversion Chart (Using a while loop)
```java
public class Lab5_Problem1 {
public static void main(String[] args) {
// Chart 1: Fahrenheit to Celsius Conversion
fahrenheitToCelsiusWhile(0, 212);
}
public static void fahrenheitToCelsiusWhile(int start, int end) {

The most common delimiter is a comma. The correct option is d.
What is a delimiter?
Programming languages employ delimiters to define code set characters or data strings, operate as data and code boundaries, and make it easier to comprehend code and divide up distinct implemented data sets and functions.
The values may be separated by any character, however, the comma, tab, and colon are the most often used delimiters. Space and the vertical bar, which is sometimes known as pipe, are occasionally utilized.
With one entry per row, data is organized in rows and columns in a delimited text file. Field separator characters are used to divide each column from the one after it. According to Comma Separated Value, one of the most popular delimiters is the comma.
Therefore, the correct option is d, comma.

In the event that a thread loses access to the cpu, such as via a time-out, sleep, block, or wait state, what happens when the thread is ready to resume execution?
Answers
Answer:
The thread is moved to the back of the Ready Queue
When the thread is ready to resume execution, the thread is moved to the rear of the ready-queue.
What is Thread?A thread of execution is the smallest possible sequence of programmed instructions that can be managed independently by an operating system scheduler in computer science. The execution of strings and cycles contrasts between working frameworks. Tanenbaum demonstrates in Modern Operating Systems that a variety of process organization models are feasible. A thread is frequently a part of a process. Through multithreading capabilities, a process's multiple threads can execute at the same time and share resources like memory, whereas distinct processes do not. A process's executable code, dynamically allocated variables, and non-thread-local global variables are shared by all threads at any given time.
In the event that a thread loses access to the CPU, such as via a time-out, sleep, block, or wait state, it will be at rear of ready queue.
The addition of new items occurs at one end, known as the "rear," and the removal of existing items occurs at the opposite end, known as the "front." A queue is an organized collection of items. An element moves from the back of the queue toward the front as it enters the queue, waiting to be removed as the next element.
Therefore, The thread is moved to the back of the ready-queue when it is ready to resume execution.
