Answer:

Before we must check a series of steps to try to identify the problem:

-Problems with the electric current or the battery may be discharged

- Disadvantages with the PC power supply

-Problems with the motherboard, memory or processor

-Disadvantages with hard disk boot

- Disadvantages with the BIOS or its battery

Explanation:

If even reviewing the previous steps, the computer still does not start up then the problem may be due to the hardware, so it is very important to examine the physical part and the system, in order to show in what state the whole system is. If it is verified that the physical components are well, then the problem could be the software.

Well... I would think the BIOS, but this seems broad. It could be the operating system, it could be the CPU having some sort of issue, or some sort of error message that could originate from alot of places. The most probable would be the Motherboard BIOS or a problem with the operating system to me

Write a Java program that prompts the user to enter integer values for the sides of a triangle and then displays the values and
satela [25.4K]

Answer:

import java.util.Scanner;

public class triangle {

       public static void main (String [] args) {

           int sideOne, sideTwo, sideThree;

           Scanner in = new Scanner (System.in);

           System.out.println("Enter the first side of the triangle");

           sideOne = in.nextInt();

           System.out.println("Enter the secon side of the triangle");

           sideTwo = in.nextInt();

           System.out.println("Enter the third side of the triangle");

           sideThree = in.nextInt();

           if ( sideOne<=0||sideTwo<=0|| sideThree<=0){

               System.out.println(" The Values enter are "+sideOne+ "," +sideThree+ ","+sideThree+ " These values don't make a valid triangle");

           }

           else if ((sideOne + sideTwo> sideThree) || (sideOne+sideThree > sideTwo) || (sideThree+sideTwo > sideOne))

           {

               System.out.println ("The triangle is Valid");

           }

           else {

               System.out.println(" The Values enter are "+sideOne+ "," +sideTwo+ ","+sideThree+ " These values don't make a valid triangle");

           }

       }

Explanation:

for a Triangle to be Valid one of the three sides of the triangle must greater than the other two sides.  The code above enforces this condition using an if statement in combination with the Or Operator

The following conditions where enforced

side one, side two and side three != 0

Side One + Side Three > Side Two

Side Three + Side Two> Side One

Side Two + Side One > Side Three

You have been employed as a technical consultant to a computer shop chain. You are given the task of creating a short consumer b
brilliants [131]

Answer:

The five factors to consider when trying to choose between a Solid State Drive, a Hard Disk Drive and, an External Hard Disk Drive are:

  1. Read/Write Speed
  2. Weight
  3. Power Consumption
  4. Cost
  5. Storage Capacity

  • Solid State Drives (SSDs) are typically lighter in weight, faster and do not consume much power.
  • Hard Disk Drives are relatively cheaper than SSDs. They also come with higher storage capacities but are more power-hungry and slower because they rely on mechanical/moving parts to read and write data.
  • External HDDs are the cheapest of the three. They are not internal which is a major drawback given the additional weight. However, they come with gargantuan storage capacities that make you want to rethink having one. Besides, unlike SSDs, you can easily get them in computer accessories shops offline or online.

Cheers!

Ilya [14]

Answer:

Option is b is correct answer. Excel performs exponentiation, then multiplication and division, then addition, and subtraction, it is correct order of operation in Excel. It is important to remember when you write any formula in Excel having different mathematical operators like +/ -/ ^/  etc, it follows a specific order and performs calculations in specific order which is termed as order of operator precedence. Each of mathematical operator has its precedence and executes in a special order set by Excel.

Explanation:

  • As we already know order of precedence of each mathematical operator is different in Excel. The order of operations for Excel is as follows:

  • Evaluate elements in parentheses.
  • Evaluate 'ranges' ().  
  • Evaluate 'intersections' (empty spaces).  
  • Evaluate 'unions' (,).
  • Perform negation (-).  
  • determine percentages (%).  
  • Perform exponentiation (^).  
  • Perform multiplication (*) and division (/), both are of equal precedence.  
  • Perform addition (+) and subtraction (-), both are of equal precedence.  
  • Evaluate text operators like (&).  
  • Perform comparisons like (=, <>, <=, >=).
