Assignment 2 Directions Please choose Option 1 or Option 2. You do not need to do both. Option 1: Please write a short paper based on Module 2 Hardware Components. Anything in the module can be a topic. Write a summary paper as follows: • Prepare a Word document with a minimum of 3 pages (not including title and references pages) and a minimum of 3 solid references. Be sure to use APA Guidelines for references. • Make sure to save the file in the following format: FirstName_LastName_Paper.doc(x) • Upload the completed file as an attachment to this assignment. . Option 2: 1. Create an algorithm to add two integer numbers. 2. Implement the program in a high level language like C or Java. It does not need to run for me, but the code should be included in a text document called FirstnameLastnameHLA2.txt in your assignment submission. 3. Implement the program in MIPSzy Assembly language. Use the high level code as comments to the right of the Assembly code as the textbook does. 4. If you…

How can developers prevent and handle common file-related exceptions such as file not found, permission denied, and file I/O errors? Provide code examples if possible.

CHAPTER 2 EXPLORING THE UNIX/LINUX FILE SYSTEMS AND FILE SECURITY Create a file called samp1e1.View the files present in the current directory in the long listing format.By default the permissions for a file will be rw-rw-r--, change the permissions of the sample1 file to rwxr--r-x, using the rwx notation.View the files present in the current directory in the long listing format.Create a second file called sample2.By default the permissions for a file will be rw-rw-r--, change the permissions of the sample2 file to rwxr-x--x, using 421 method.View the files present in the current directory in the long listing format.STEP BY STEP PLEASE!! ALSO SHOW SCREENSHOTS PLEASE!

1- Which of the following is wrong? a) for an ASP.NET Core MVC project, the right place to write Javascript code is in Controller file. b) Models in MVC are typically c# classes that generally hold data from a database c) View files contain HTML and razor markup code d) Controller files are c# classs files that contain action methods. Leave blank

Select all true statements Hard links are a type of file that names another file/directory path Multiple hard links can point to the same l-Node Soft links are a type of file that names another file/directory path O Hard links point to l-Nodes Soft links can be used to subvert user permissions Multiple soft links can point to the same l-Node O Soft links point to l-Nodes

Why do you feel file extensions are important? Please provide a comprehensive justification for your position. You have the option of naming three different file extensions in a folder that is chosen at random on your computer. You are welcome to additionally mention the names of any software programmes that were used to build them, if you so choose. It should be possible to open the majority of file extensions by right-clicking on a file and selecting properties from the resulting pop-up menu (Microsoft Windows environment).

20. Create a linux bash script to get a filename as input and then it should check and display if file exist and size is greater than zero, then should get input of any file comparison operator and then display if the file is true or false for that given file comparison operator. 21. Create a linux bash script to get three numbers as positional parameters then display the greatest and least of the given numbers. If positional parameters are not given then message "This script requires 3 numbers as positional parameters, Try again.." should be displayed.

Exercise 1.3 : Approximation of functions The function (1) = can be approximated by the series ()~1+x+パ++ as long as x] < 1. We would like to explore how many terms are needed to make the difference between f(x) and this series approximation smaller than a given tolerance. For example, for an error of 1x 10- and x=0 only one term from the series is needed, while for x=1/2 = 2 1-(1/2) and 1. 1. 1+ラt * - 1.9375 22 so n=5 terms is enough for an error of 1 x 10" and x1/2 (a) Write a function void numberofTerms (double x, double error, int n) that will for any value of x less then 1 in magnitude compare the series to the exact function and determine the minimum number of terms needed to make their difference less than a specified error. Make sure you protect your function against bad inputs using control structures. (b) Write a driver program that tests the function numberofTerms written in 1.3(a).

Code A (below) first checks the status of a file and then opens it and uses it. It contains a vulnerability.Explain what the vulnerability is and why Code B (below) resolves the vulnerability.

INTRODUCTION You are a network administrator who is responsible for 100 users and 20 servers for a medium size business. As an administrator who has multiple tasks to get done throughout the day, you need to develop a Power Shell script to help you manage routine tasks that you have to take care of everyday. To simplify your administration create a script with the following objectives OBJECTIVES Script that will create multiple folders using a do loop and variable CREATE MULTIPLE FOLDER SCRIPT GUIDELINES SETTING UP THE VARIABLES: Open PowerShell ISE • Create a variable Sintfolders that has a value of 10 • Create a variable SintPad that has a value of0 • Create a variable $i that has a value of 1 • Create a variable for the new folder • New-Variable -Name strPrefix -Value "testfokder" –Option constant CREATING THE LOOP STATEMENT • Do { • Set If condition o if (Si -k 10) • Set Command when Condition is True O {New-Item -path C: -name SstrprefixSintpad$i –type directory} Set Command when…

44. In SCAN – EDF, requests with the same deadlines are ordered according to : a. SCAN policy b. EDF policy c. FCFS policy d. FIFO policy

UNIX ASSIGNMENT - IXQuestion 2: Write a command to list all the files inside a folder i.e. if there is a folder inside a folder then it should list all files inside the sub-folder which is inside the folder to be listed.

Differentiate write – invalidate policy from write – update policy

You should make a list of the most common file attributes and actions, as well as a short description for each one.

Create a script that will allow a script user to add or remove permissions (read, write, execute) from a file of their choosing. The script must have the following components: • The script must utilize 3 or more functions. The script must utilize a menu that the script user can use to perform an action. The script must use conditional statements, where applicable, to handle the following situations: o The filename provided by the script user does not exist. o An incorrect option was chosen by the script user at the menu. The script's menu must also provide a way for the script user to have the following choices: o Select another file (i.e. once a file's permissions has been changed). o Exit the script

User Log-in Objective: At the end of the activity, the students should be able to: • Create a program that handles exception and allows writing to and reading from a text file. Software Requirements: Latest version of NetBeans IDE • Java Development Kit (JDK) 8 Procedure: 1. Create a folder named LastName_FirstName (ex. Reyes_Mark) in your local drive. 2. Create a new project named TaskPerf6. Set the project location to your own folder. 3. Write a program that will: a. Ask the user to select between two (2) options: • Register: User shall input his desired username and password. These shall be saved in a text file named records.txt. Only alphanumeric characters are allowed. Login: User is asked to input a username and password. Validate using the text file created from the Register option. If both the username and password are correct, display the message "Successfully logged in", else, display “Incorrect username or password".

Explain in detail what you consider a file extension to be and what function you think it fulfills. Go to a random folder on your computer and name three file extensions you see there, as well as any software programs that may have produced them. Most file extensions should be shown by simply right-clicking on a chosen file and choosing properties from the pop-up menu (Microsoft Windows environment).
