Answer:
4. Command line interface (CLI)
Explanation:
An operating system is a system software pre-installed on a computing device to manage or control software application, computer hardware and user processes.
This ultimately implies that, an operating system acts as an interface or intermediary between the computer end user and the hardware portion of the computer system (computer hardware) in the processing and execution of instructions.
Some examples of an operating system on computers are QNX, Linux, OpenVMS, MacOS, Microsoft windows, IBM, Solaris, VM etc.
A Command line interface (CLI) refers to a text-based user interface that allow users to operate a software application or program, as well as manage and execute operating system functions by typing standard line of commands into the text-based user interface with a real-time response.
Basically, the CLI is solely text-based and as such requires a thorough knowledge and understanding of global commands, as well as administrative privileges in some cases.
<em>Hence, the operating system function which has a steeper learning curve (more difficult to learn) and can potentially break the system without careful use of its operations is the Command line interface (CLI). </em>
Answer:
import java.util.*;
public class Main{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
int intgVal; double dblVal; char chrVal; String strVal;
System.out.print("Enter integer: ");
intgVal = input.nextInt();
System.out.print("Enter double: ");
dblVal = input.nextDouble();
System.out.print("Enter character: ");
chrVal = input.next().charAt(0);
input.nextLine();
System.out.print("Enter string: ");
strVal = input.nextLine();
System.out.println(intgVal+" "+dblVal+" "+chrVal+" "+strVal);
System.out.println(strVal+" "+chrVal+" "+dblVal+" "+intgVal);
int IntValue = (int) dblVal;
System.out.print("Cast to an integer: "+IntValue);
}
}

relative.
<h2><u>
Explanation:</u></h2>
The coordinates for the section element need not be defined as long as its position is set to relative.
If the position is set as relative, then it will have no effect on the positioning attributes, it will consider as static position. If positioning is mentioned explicitly like top: 20px; then it will position 10 pixels down from where it is located. An ability for positional shifts is extremely helpful.
Two things happen when an element is set as relative, one is it introduces the ability to use z-index on that element, second is it limits the scope of absolutely positioned child elements.
Answer:
This question was initially incomplete. Here is the full question:
Many Web browsers allow users to open anonymous windows. During a browsing session in an anonymous window, the browser does not record a browsing history or a list of downloaded files. When the anonymous window is exited, cookies created during the session are deleted. Which of the following statements about browsing sessions in an anonymous window is true?
a) The activities of a user browsing in an anonymous window will not be visible to people who monitor the user's network, such as the system administrator.
b) Items placed in a Web store's shopping cart for future purchase during the anonymous browsing session will not be saved on the user's computer.
c) A user will not be able to log in to e-mail or social media accounts during the anonymous browsing session.
d) A user browsing in an anonymous window will be protected from viruses launched from any Web sites visited or files downloaded.
The correct answer is b) Items placed in a Web store's shopping cart for future purchase during the anonymous browsing session will not be saved on the user's computer.
Explanation:
For e-commerce sites, shopping cart information are stored as cookies on the visitor's computer such that when the website visitor leaves the website and comes back a few days later, their shopping preferences are remembered.
If the website visitor uses an anonymous window, the cookies created during the browsing session will be deleted when the anonymous website is exited and so, items placed in the shopping cart for future purchase will not be saved.
