There are 3 processes (A, B and C). A has a duration of 4s, B has a duration of 4s, and C has a duration of 6s. They arrive at the same time when T=0s. What is the average turnaround time in the shortest-job-first and shortest-remaining-time-first scheduling algorithms respectively? You must explain your answer

Answers

Answer 1

In the shortest-job-first (SJF) scheduling algorithm, the process with the shortest duration is executed first. The average turnaround time in the shortest-job-first is 8.67 and the average turnaround time in shortest-remaining-time-first  is 8.67.

In the given scenario, processes A, B, and C arrive at the same time when T=0s, with durations of 4s, 4s, and 6s, respectively.

To calculate the average turnaround time in the SJF scheduling algorithm, we need to determine the order in which the processes will be executed.

Shortest-Job-First (SJF) Scheduling Algorithm:

1.

The shortest job first is A with a duration of 4s. Then, the remaining processes are B and C with durations of 4s and 6s, respectively.Since B and C have the same duration, we follow the rule of priority based on arrival time. As they arrived simultaneously at T=0s, B is given priority over C.Therefore, the execution order is A -> B -> C.

Now, let's calculate the turnaround time for each process:

Turnaround time for process A: 4s (A's duration)Turnaround time for process B: 8s (A's duration + B's duration)

   Turnaround time for process C: 14s (A's duration + B's duration + C's duration)

To find the average turnaround time, sum up the turnaround times and divide by the total number of processes:

Average Turnaround Time = (4s + 8s + 14s) / 3 = 26s / 3 ≈ 8.67s

2.

Shortest-Remaining-Time-First (SRTF) Scheduling Algorithm:

The process with the shortest remaining time is A with a duration of 4s.Then, we have B and C with durations of 4s and 6s, respectively.Again, since B and C have the same duration, we follow the rule of priority based on arrival time, giving priority to B.Therefore, the execution order is A -> B -> C.

Calculating the turnaround time for each process:

Turnaround time for process A: 4s (A's duration)Turnaround time for process B: 8s (A's duration + B's duration)Turnaround time for process C: 14s (A's duration + B's duration + C's duration)

The average turnaround time is calculated similarly:

Average Turnaround Time = (4s + 8s + 14s) / 3 = 26s / 3 ≈ 8.67s

In both the SJF and SRTF scheduling algorithms, the average turnaround time is approximately 8.67 seconds. This is because both algorithms follow the same order of execution based on the process durations and arrival times, resulting in the same sequence and turnaround times for the processes.

A Dante device's average default delay is 1 ms. This is enough for a very big network that consists of 100 megabit lines to Dante devices and a gigabit network core (with up to 10 hops between edge switches).

The term "latency" refers to the minute amount of time (10 milliseconds in the case of Dante Via) that is added to each audio stream. Via may 'packetize' the audio from the source and send it across the network to the destination before it is scheduled to be played out thanks to the minor delay. Audio and control are combined into one potent network because computer control and recording signals go over the same connections as the audio data.

False.

In contrast, the WHERE clause is used to filter the rows returned by a SELECT statement based on specific criteria. The WHERE clause cannot contain aggregate functions because it is used to filter individual rows, not perform calculations on a set of values.

The user could type “add”, “Add”, “ADD”, or “+”, to name a few possibilities. Of course, as humans, we know exactly what is meant, even if the word is capitalized. But the Python Interpreter can’t tell that “add” is the same as “Add”.

The Python programming language is a great tool to use when working with numbers and evaluating mathematical expressions. This quality can be utilized to make useful programs.

This tutorial presents a learning exercise to help you make a simple command-line calculator program in Python 3. While we’ll go through one possibile way to make this program, there are many opportunities to improve the code and create a more robust calculator.

We’ll be using math operators, variables, conditional statements, functions, and handle user input to make our calculator.

Prerequisites

For this tutorial, you should have Python 3 installed on your local computer and have a programming environment set up on the machine. If you need to either install Python or set up the environment, you can do so by following the appropriate guide for your operating system.

Step 1 — Prompt users for input

Calculators work best when a human provides equations for the computer to solve. We’ll start writing our program at the point where the human enters the numbers that they would like the computer to work with.

To do this, we’ll use Python’s built-in input() function that accepts user-generated input from the keyboard. Inside of the parentheses of the input() function we can pass a string to prompt the user. We’ll assign the user’s input to a variable.

For this program, we would like the user to input two numbers, so let’s have the program prompt for two numbers. When asking for input, we should include a space at the end of our string so that there is a space between the user’s input and the prompting string.

number_1 = input('Enter your first number: ')

number_2 = input('Enter your second number: ')

After writing our two lines, we should save the program before we run it. We can call this program calculator.py and in a terminal window, we can run the program in our programming environment by using the command python calculator.py. You should be able to type into the terminal window in response to each prompt.

Output

Enter your first number: 5

Enter your second number: 7

If you run this program a few times and vary your input, you’ll notice that you can enter whatever you want when prompted, including words, symbols, whitespace, or just the enter key. This is because input() takes data in as strings and doesn’t know that we are looking for a number.
