Answer
Cyber Security professionals
Explanation
Cyber security professionals can help the company protect itself from hackers. They are experts who will install antivirus into the software used in the company to protect virus manipulation and prevent malware. They will further encrypt the websites of the company and reset the password of the computers into two-factor authentications to make the login requirements advanced.
Answer:
See Explaination
Explanation:
public class testscope
{
//start of main function
public static void main(String[] args)
{
//varible declration
int i;
int x;
//loop for 10 times
for(i=0; i<10; i++)
{
//initialize value of x to 10
x = 10;
}
//the scope of variable x is visible outside of for loop
System.out.println("The value of x is: "+x);
}
}
See attachment for sample output
nb:
You can clearly see in the output of Java program the value of x is not printed and program return errors. It means the variable x declared inside for loop does not has scope outside the for loop.
Answer:
Sedimentary Rocks
Explanation:
Sedimentary rocks are essentially the Frankenstein monsters of the rock world. They're made up of pieces of igneous and metamorphic rocks, sand, clay, and other sedimentary rocks.
Answer: Memory hierarchy is the hierarchy that is created on the basis of the response time of different memories. The performance obtained by the memory helps in creating a computer storage space in distinguished form. The factors considered for the creating of the hierarchy structure are usually response time, storage capacity, complexity etc.
Usage of different kind of memories take place due to different kind of requirements from the system which cannot be fulfilled using one memory device.The requirement is based on saving time, decreasing complexity , improving performance etc.Example of requirements can be like some functions and files do not require much space , some might require quick accessing,etc.
Thus hierarchy of any particular system is in the form of fast to slow order from registers,cache memory, Random access memory(RAM) and secondary memory.
