The file that contains full and incremental back-up information for use with the dump/restore utility is <u>/etc/dumpdates.</u>
<u></u>
<h3>What is dump/restore utility ?</h3>
Dump examines files in a filesystem, determines which ones need to be backed up, and copies those files to a specified disk, tape or other storage medium. Subsequent incremental backups can then be layered on top of the full backup.
The restore command performs the inverse function of dump; it can restore a full backup of a filesystem. Single files and directory subtrees may also be restored from full or partial backups in interactive mode.

The block most effectively keep a sprite from moving off the screen if if on edge, bounce. Hence option B is correct.
<h3>
What is screen?</h3>
Screen is defined as a portable or stationary object that offers shelter, acts as a partition, etc., and often consists of a covered frame. Screening is defined as the procedure of locating or choosing individuals from a community according to one or more selection criteria.
The block will kept more perfectly if one of the edge there is bounce so that the box will not fall from the sprite.
Thus, the block most effectively keep a sprite from moving off the screen if if on edge, bounce. Hence option B is correct.

It would be the social standing of a person and the economic standing of a person.
Answer:
2. <em>A reference of type A can be treated as a reference of type B</em> - False
Base class or its objects are not related to their derived class (or its objects).
Explanation:
class A {
int a;
public A() {
a = 7;
}
}
class B extends A {
int b;
public B() {
b = 8;
}
}
///////////////////////////////////////////////////////////////////////////////////////////////////////
1. <em>After the constructor for class B executes, the variable a will have the value 7 </em>- True.
When an object of a derived class is declared, the constructor of base class is called before the constructor of derived class (is called).
3. <em>Both variables a and b are instance variables </em>- True.
Classes can have instance, or member, variables and methods.
4.<em> After the constructor for class B executes, the variable b will have the value 8</em> - True.
When object of class B is declared, its constructor was called, which initialized variable b to 8.
