Explanation:

A three way handshake is a method to create a connection between host and server.It is used in a TCP/IP network.

To establish a connection three steps are followed which are as following:-

The host or sender sends a data packet called SYN to the server or receiver.It's purpose is to as if the receiver is open for new connections.
When the receiver receives the SYN packet it responds with an ACK or SYN/ACK packet as a confirmation for the connection.
When the sender receives the SYN/ACK packet and it respond with ACK packet.

Answer:

three-way handshake is a process that is used in a TCP/IP network to make a connection between the server and client.

Explanation: This 3-way TCP, is a three-step process that requires both the client and server to exchange synchronization and acknowledgment packets before the real data communication process starts.

The three-way handshake process is designed in such a way that both ends help you to initiate, negotiate, and separate TCP socket connections at the same time. It allows you to transfer multiple TCP socket connections in both directions at the same time.

Create a program that calculates the tip and total for a meal at a restaurant. Type the code into an IDLE IDE editor window and

Nataly [62]

Missing details:

The formula for calculating the tip amount is:

tip = cost of meal * (tip percent / 100)

The program should accept decimal entries like 52.31 and 15.5.

Assume the user will enter valid data.

The program should round the results to a maximum of two decimal places.

Answer:

In Python:

print("Tip Calculator")

cost_meal = float(input("Enter Cost of Meal: "))

tip_percent = float(input("Enter Tip Percent: "))

tip_amount = cost_meal * tip_percent / 100

total_amount = tip_amount + cost_meal

print("Tip amount: "+str(round(tip_amount,2)))

print("Total amount: "+str(round(total_amount,2)))

Explanation:

This line prints the string "Tip "Calculator"

print("Tip Calculator")

This lime prompts user for cost of meal

cost_meal = float(input("Enter Cost of Meal: "))

This lime prompts user for tip percemtage

tip_percent = float(input("Enter Tip Percent: "))

This line calculates the tip amount

tip_amount = cost_meal * tip_percent / 100

This line calculates the total amount

total_amount = tip_amount + cost_meal

This line prints the tip amount

print("Tip amount: "+str(round(tip_amount,2)))

This line prints the total amount

print("Total amount: "+str(round(total_amount,2)))
