A quick fix of an unnamed under-performing computer system decreases the number of stores by 50%, increases the number of ALU operations by 20%, and increases the number of loads by 20%. The original system took 1 clock cycle per ALU instruction, and 2 clock cycles for all other instructions. In the new system, stores take 3 clock cycles, branches now take 2 clock cycles and loads and ALUs only take 1 clock cycle. Evaluate the effects of the modification quantitatively by computing the speedup associated with it.

Design a class tictactoe that: holds the following information about the game: two-dimensional array (3 by 3), and winner. add additional variables as needed. includes the functions to perform the various operations on objects. for example, function to print the board, getting the move, checking if move is valid, determining if there is a winner after each move. add additional operations as needed. includes constructor(s). write the functions of the class, and write a program that uses the class. the program should declare an object of type tictactoe. the program will create the board and store it in the array. the program will allow two players to play the tic-tac-toe game. after every valid move update the array, check if there is a winner. if there is no winner and no tie, then print the board again to continue.

Auser is given read permission to a file stored on an ntfs-formatted volume. the file is then copied to a folder on the same ntfs-formatted volume where the user has been given full control permission for that folder. when the user logs on to the computer holding the file and accesses its new location via a drive letter, what is the user's effective permission to the file? a. read b. full control c. no access d. modify e. none of the above
