Answer:

Static scoping: x is 5

Dynamic scoping : x is 10.

Explanation:

Static scoping :

In static scoping the variable of a function take the value within the function.

If there is no values exist within the function then take the global value of the variable.

var x // No value is assigned to x so it check global value of x

function sub1() {

   document.write(“x = “ + x + “”); // So it print x = 5

}

function sub2() {

   var x;

   x = 10;

   sub1();

}

x = 5; // It is the global value of x

sub2();

Static scoping: x is 5

Dynamic scoping :

In Dynamic scoping the variable of a function take the value all the calling function ends.

If the global value is the last assigned value of a variable then it take that value.

If there exist some other function after global variable value if that function contain the variable with some assigned value variable take that value.

var x

function sub1() {

   document.write(“x = “ + x + “”);

}

x = 5; // At this point x value is 5 and check there exist a function

sub2(); // So now call this function

function sub2() {

   var x;

   x = 10; // The value of x = 5 is replaced with x = 10

   sub1();

}

Dynamic scoping : x is 10.

What impact did congress declaration on copyrighting sound recordings have on home recording and record sales
cricket20 [7]

Answer:

By the late 1980s, several manufacturers were prepared to introduce read/write digital audio formats to the United States. These new formats were a significant improvement over the newly introduced read-only (at the time) digital format of the compact disc, allowing consumers to make perfect, multi-generation copies of digital audio recordings. Most prominent among these formats was Digital Audio Tape (DAT), followed in the early 1990s by Philips' Digital Compact Cassette (DCC) and Sony's Minidisc.

DAT was available as early as 1987 in Japan and Europe, but device manufacturers delayed introducing the format to the United States in the face of opposition from the recording industry. The recording industry, fearing that the ability to make perfect, multi-generation copies would spur widespread copyright infringement and lost sales, had two main points of leverage over device makers. First, consumer electronics manufacturers felt they needed the recording industry's cooperation to induce consumers – many of whom were in the process of replacing their cassettes and records with compact discs – to embrace a new music format. Second, device makers feared a lawsuit for contributory copyright infringement.[1]

Despite their strong playing hand, the recording industry failed to convince consumer electronics companies to voluntarily adopt copy restriction technology. The recording industry concurrently sought a legislative solution to the perceived threat posed by perfect multi-generation copies, introducing legislation mandating that device makers incorporate copy protection technology as early as 1987.[2] These efforts were defeated by the consumer electronics industry along with songwriters and music publishers, who rejected any solution that did not compensate copyright owners for lost sales due to home taping.[3]

The impasse was broken at a meeting in Athens in 1989, when representatives from the recording industry and the consumer electronics industry reached a compromise intended to enable the sale of DAT recorders in the United States. Device manufacturers agreed to include SCMS in all consumer DAT recorders in order to prevent serial copying. The recording industry would independently pursue legislation requiring royalties on digital audio recording devices and media.[4]

A year later the songwriter Sammy Cahn and four music publishers, unhappy with the absence of a royalties provision in the Athens agreement, filed a class action copyright infringement suit against Sony.[5] The plaintiffs sought declaratory and injunctive relief that would have prevented the manufacture, importation or distribution of DAT recorders or media in the United States. The suit brought Sony to heel. In July 1991, Sony, as part of larger agreement between the recording industry and consumer electronics makers, agreed to support legislation creating a royalty scheme for digital media. In exchange, Cahn and the publishers agreed to drop the suit.[6]

With all the major stakeholders satisfied, the bill easily passed both houses of Congress. President George H. W. Bush signed the AHRA into law in 1992 proclaiming " S. 1623 [AHRA] will ensure that American consumers have access to equipment embodying the new digital audio recording technology. It also protects the legitimate rights of our songwriters, performers, and recording companies to be fairly rewarded for their tremendous talent, expertise, and capital investment. This will be accomplished by fairly compensating these artists for the copying of their works and by creating a system that will prevent unfettered copying of digital audio tapes."

Question 2 of 10
horrorfan [7]

Answer:

Lowest Level; Machine Language.

Explanation:

The lowest level of a computer is machine language, which are strings of 0's and 1's in bits, and it's possible to perform tasks at this level. It's however difficult to do and humans created <em>Assembly</em>; a type of low level programming language to be readable, and converts to machine language so that we don't have to work in binary.

The return value is a one-dimensional array that contains two elements. These two elements indicate the rows and column indices
erma4kov [3.2K]

Answer:

In Java:

import java.util.Scanner;  

import java.util.Arrays;  

public class Main  {  

public static void main(String args[])  {  

Scanner input = new Scanner(System.in);

int row, col;  

System.out.print("Rows: ");    row = input.nextInt();

System.out.print("Cols: ");     col = input.nextInt();  

int[][] Array2D = new int[row][col];

System.out.print("Enter array elements: ");

for(int i =0;i<row;i++){    

    for(int j =0;j<col;j++){

        Array2D[i][j] = input.nextInt();  

    }     }

 

int[] maxarray = findmax(Array2D,row,col);

System.out.println("Row: "+(maxarray[0]+1));

System.out.println("Column: "+(maxarray[1]+1));

}  

public static int[] findmax(int[][] Array2D,int row, int col)   {  

int max = Array2D[0][0];

int []maxitem = new int [2];

for(int i =0;i<row;i++){

    for(int j =0;j<col;j++){

        if(Array2D[i][j] > max){  

            maxitem[0] = i;

            maxitem[1] = j; } }    }

 

return maxitem;  

}  

}

Explanation:

The next two lines import the scanner and array libraries

<em>import java.util.Scanner;   </em>

<em>import java.util.Arrays;   </em>

The class of the program

<em>public class Main  {  </em>

The main method begins here

<em>public static void main(String args[])  {  </em>

The scanner function is called in the program

<em>Scanner input = new Scanner(System.in);</em>

This declares the array row and column

int row, col;

This next instructions prompt the user for rows and get the row input  

System.out.print("Rows: ");    row = input.nextInt();

This next instructions prompt the user for columns and get the column input  

System.out.print("Cols: ");     col = input.nextInt();  

This declares the 2D array

int[][] Array2D = new int[row][col];

This prompts the user for array elements

System.out.print("Enter array elements: ");

The following iteration populates the 2D array

<em> for(int i =0;i<row;i++){    </em>

<em>     for(int j =0;j<col;j++){ </em>

<em>         Array2D[i][j] = input.nextInt();   </em>

<em>     }     } </em>

This calls the findmax function. The returned array of the function is saved in maxarray  

int[] maxarray = findmax(Array2D,row,col);

This prints the row position

System.out.println("Row: "+(maxarray[0]+1));

This prints the column position

System.out.println("Column: "+(maxarray[1]+1));

The main method ends here

}  

The findmax function begins here

public static int[] findmax(int[][] Array2D,int row, int col)   {  

This initializes the maximum to the first element of the array

int max = Array2D[0][0];

This declares maxitem. The array gets the position of the maximum element

int []maxitem = new int [2];

The following iteration gets the position of the maximum element

<em>for(int i =0;i<row;i++){ </em>

<em>     for(int j =0;j<col;j++){ </em>

<em>         if(Array2D[i][j] > max){  </em>

<em>             maxitem[0] = i; </em><em>-- The row position is saved in index 0</em><em> </em>

<em>             maxitem[1] = j;  </em><em>-- The column position is saved in index 1</em><em>} }    } </em>

This returns the 1 d array

return maxitem;  

}
