Answer:
The four-step process of fetch, decode, execute, and store. Type of memory where the contents of this are not erased when the computer is turned off.
Answer:
The answer is Coarse wavelength division multiplexing (CWDM)
Explanation:
CWDM is the wavelength designed for short- distance connections and has only a few lambdas. It is mostly used nowadays as a type of wavelength technologies deployed in cities and inner access ways. It is inexpensive and thus a cost effective wavelength division multiplexing. Cost effective lasers can be used in CWDM due to the spacing of about 20nm between its wavelengths.
Answer:
The program to this question can be given as:
Program:
public class Main //define class.
{
public static void main(String[] as) //define main method.
{
int n=5; //define variable n and assign positive value.
int i,j; //define variable
for (i = 7; i>=1; i--) //outer loop.
{
for (j = 0; j< i; j++) //inner loop.
{
System.out.print("*"); //print asterisks.
}
System.out.println(); //line break.
}
}
}
Output:
*****

Explanation:
The description of the above code can be given as:
- In the above java programming code firstly we define a class that is "Main". In this class we define a main method in the main method we define a variables that is "n" in this variable we assign a positive value. The we define another integer variable that is i,j this variable is used in the loop.
- Then we define a loop. for prints asterisks values in reverse triangle, we nested looping concept. In nested looping, we use in loop in this loop we use the i and j variables that print the asterisks value.
Answer:
Spyware
Explanation:
Internet is a type of computer network that allow device communicate with each other world wide. So, it is not the correct option.
Worm: this is a standalone malware computer program that replicates itself in order to spread to other computers. It spreads copies of itself from computer to computer. A worm can replicate itself without any human interaction, and it does not need to attach itself to a software program in order to cause damage. The major feature of a worm is ability to replicate on it own. So, it is not the correct option.
Bot: this is a software application that runs automated tasks. So, it is not the correct option.
Middleware: this is software that lies between an operating system and the applications running on it, enabling communication and data management. It provides services to software applications beyond those available from the operating system. So, it is not the correct option.
Spyware: this is the correct answer. Spyware is similar to trojan horse because it hides itself in a system and a user may not know that it exist on the system. Spyware is a form of malware that hides on your device, monitors your activity, and steals sensitive information without knowledge of the user.
