Concept explainers
The “Persmission” defines what a user or group can do to an object such as a file or folder.
Explanation of Solution
Permission:
Computer holds many files and folders. Each file and folder has an authorized creator and user. Not all users are allowed to access files, folders, and contents in files and folders. For every object in files and folders, there are different properties.
Permission is one of the properties of object. Only the users who have privilege can use and perform some actions. If read only permission is given to user, then user is allowed only to read the contents of file but would not allowed to edit or change contents of file or folder.
File creator or network administrator or system admin defines the file and folder permissions. If a word file is given (read/write) permission, then user can read and update contents of file and save the file.

- Based on the given problem, create an algorithm and a block diagram, and write the program code: Function: y=xsinx Interval: [0,π] Requirements: Create a graph of the function. Show the coordinates (x and y). Choose your own scale and show it in the block diagram. Create a block diagram based on the algorithm. Write the program code in Python. Requirements: Each step in the block diagram must be clearly shown. The graph of the function must be drawn and saved (in PNG format). Write the code in a modular way (functions and the main part should be separate). Please explain and describe the results in detail.arrow_forwardQuestion: Based on the given problem, create an algorithm and a block diagram, and write the program code: Function: y=xsinx Interval: [0,π] Requirements: Create a graph of the function.

- You are working with a database table that contains customer data. The table includes columns about customer location such as city, state, and country. You want to retrieve the first 3 letters of each country name. You decide to use the SUBSTR function to retrieve the first 3 letters of each country name, and use the AS command to store the result in a new column called new_country. You write the SQL query below. Add a statement to your SQL query that will retrieve the first 3 letters of each country name and store the result in a new column as new_country.arrow_forwardWe are considering the RSA encryption scheme. The involved numbers are small, so the communication is insecure. Alice's public key (n,public_key) is (247,7). A code breaker manages to factories 247 = 13 x 19 Determine Alice's secret key. To solve the problem, you need not use the extended Euclid algorithm, but you may assume that her private key is one of the following numbers 31,35,55,59,77,89.arrow_forwardConsider the following Turing Machine (TM). Does the TM halt if it begins on the empty tape? If it halts, after how many steps? Does the TM halt if it begins on a tape that contains a single letter A followed by blanks? Justify your answer.arrow_forward
