Answer:
The description for the given question is described in the explanation section below.
Explanation:
Depending on the needs of the device programmers these OS have various locking frameworks. Spinlocks become beneficial for preemptive multitasking processes during which a thread will operate in such an active loop instead of risking a rest queue latency. Mutexes become beneficial to utility lockers.
- Solaris 2 employs flexible mutexes, indicating something like this on preemptive multitasking computers, the mutex is introduced with either a spinning switch.
- Semaphores and state variations are much more effective methods for consistency where a commodity needs to be managed for such a prolonged period of time because spinning is unstable over a prolonged time.
Failure in a database environment is more serious then a non data base because if you lose important information you may not get it back and failure in a nondatabase environment the problem may be more easier to solve
Answer:
// here is code in Java.
// package
import java.util.*;
// class definition
class Main
{
// method that return sum of two sale value
public static int Add(int euroSales,int asiaSales)
{
// return the sum
return euroSales+asiaSales;
}
//main method of the class
public static void main (String[] args) throws java.lang.Exception
{
try{
// variables
int euroSales=100;
int asiaSales=150;
int eurasiaSales;
// call the function
eurasiaSales=Add(euroSales,asiaSales);
// print the sum
System.out.println("total sale is:"+eurasiaSales);
}catch(Exception ex){
return;}
}
}
Explanation:
Declare and initialize two variables "euroSales=100" and "asiaSales=150". Declare another variable eurasiaSales. Call the method Add() with euroSales and asiaSales as parameter. This method will add both the value and return the sum.This sum will be assigned to variable eurasiaSales.Then print the sum.
Output:
total sale is:250
The two characteristics of scalable network are such that it
can easily grow in size without causing any impact to the current users. This means,
increase in network capacity and technical capability will not have any detrimental
effects to the users. Another characteristic
of this network is that it can work perfectly with modular devices provided
they support expansion process.
