Answer: measures how quickly a system performs a process or transaction
Explanation:
Computer performance refers to how well a given computer system performs, which is estimated by its accuracy, efficiency and speed when completing a process or transaction.
A computer performance evaluation will assess a system's resources and outputs to make sure that it´s performing in the best possible way.
Some parameters of performance are latency, speed, throughput, and bandwidth.
Answer:
True
Explanation:
for loop is used to repeat the process again and again until the condition not failed.
syntax:
for(initialize; condition; increment/decrement)
{
Statement
}
But we can omit the initialize or condition or increment/decrement as well
the syntax after omit the initialization,
for( ; condition; increment/decrement)
{
Statement
}
The above for loop is valid, it has no error.
Note: don't remove the semicolon.
You can omit the condition and increment/decrement.
and place the semicolon as it is. If you remove the semicolon, then the compiler show syntax error.
Answer:
import java.util.Scanner;
public class Supermarket
{
public static void main (String[] args)
{
String item;
double pounds, ounces, price,
total, unit;
Scanner scn = new Scanner(System.in);
System.out.print("Please enter the name of item ");
item = scn.nextLine();
System.out.print("Please enter the price of " + "the item per pound : ");
price = scn.nextDouble();
System.out.print("Enter the weight of " + "the item in pounds and " + "ounces respectively : ");
pounds = scn.nextDouble();
ounces = scn.nextDouble();
unit = price/16;
total = price * (pounds + ounces/16);
System.out.print("The unit price of " + "the products sold is : " + unit);
System.out.print("\nThe total cost of the " + "amount purchased is : " + total);
}
}
Explanation:
- Ask the user to enter the price of the item and the weight.
- Calculate the unit and the total price.
- Display the unit and the total price.
Answer:
An Intrusion Detection System (IDS) is a system that monitors network traffic for suspicious activity and issues alerts when such activity is discovered. It is a software application that scans a network or a system for harmful activity or policy breaching. Any malicious venture or violation is normally reported either to an administrator or collected centrally using a security information and event management (SIEM) system. A SIEM system integrates outputs from multiple sources and uses alarm filtering techniques to differentiate malicious activity from false alarms.
