Answer:
A. Define boundaries
C. Deny access
D. Delay access
Explanation:
A barrier is a material or structure used to prevent or block access. Barriers can either be natural or structural and are used for many purposes usually for security reasons. The following are functions of barriers either natural or structural:
- Define areas of boundaries
- Delay or slow access. Example is the use of speed bumps to slow down vehicles.
- Provide access to entrances such as the use of gates
- Deny access to unauthorized personnel and allowing authorized personnel.
Answer:
20 will be displayed on the console.
Explanation:
Given code is:
var numList = [10,20,30];
console.log(numList[numlist.length-2]);
The first line of code declares an array named numList and assigns it values given in the square brackets.
The second line of code is written to display the element on the index obtained by [numlist.length-2]
[numlist.length-2] means the second index.
Hence,
after running the code on JavaScript editor and dry running the code
20 will be displayed on the console.
Four of the basic I/O interface standard are PCI, SCSI, USB and ISA.
<h3>Standard I/O Interface</h3>
Input-Output Interface is used as an method which helps in transferring of information between the internal storage devices. A number of standards have been developed for I/O Interface.
There widely used bus standards are:
- PCI (Peripheral Component Interconnect)
- SCSI (Small Computer System Interface), and
- USB (Universal Serial Bus).
- ISA (Industry Standard Architecture)

Answer:
The answer to this question is "15 line".
Explanation:
A function is a block of ordered, portable code used to perform a single, connected operation. The syntax of function declaration can be given as:
Syntax :
returntype functionName(parameter1, parameter2); //function prototype
or declaration
returntype functionName(parameter1, parameter2) //function definition or header of the function
{
//function body.
//function implementation
//return value;
}
In the given question the header of the showDub function is on line 15.
That's why the answer to this question is "15 line".
