Answer:

B. Update the UEFI firmware

Explanation:

UEFI (Unified Extensible Firmware Interface) is a standard firmware interface for PCs. It is responsible for waking up the computer hardware components and ensure they are functioning properly.

The old processor was controlled by an older version of the UEFI but to run the new processor, you update the Firmware Interface to enable it communicate with the computer's hardware components.

Why are there so many unit testing tools? Are they efficient? Why or why not?
sineoko [7]

Answer:

 Unit testing is the software testing method in which the individual source code are associate to control data. Unit testing basically test the code to ensure that the data or information meets its design.

The aim of unit testing that each part isolate in the program and display the correct individual parts.

Unit testing tool are efficient as they provide several benefits in the development cycle. The basic efficiency of unit testing tools depend upon its type of testing. Unit testing basically validate the units of source code in the program.

For example: when the loop and function in the program work efficiently.

Define a function compute_gas_volume that returns the volume of a gas given parameters pressure, temperature, and moles. Use
jeyben [28]

Question:

Define a function compute_gas_volume that returns the volume of a gas given parameters pressure, temperature, and moles. Use the gas equation PV = nRT, where P is pressure in Pascals, V is volume in cubic meters, n is number of moles, R is the gas constant 8.3144621 ( J / (mol*K)), and T is temperature in Kelvin.

Answer:

This solution is implemented in C++

double compute_gas_volume(double P, double T, double n){

   double V = 8.3144621 * n * T/P;

   return V;

}

Explanation:

This line defines the function, along with three parameters

double compute_gas_volume(double P, double T, double n){

This calculates the volume

   double V = 8.3144621 * n * T/P;

This returns the calculated volume

   return V;

}

To call the function  from the main, use:

<em>cout<<compute_gas_volume(P,T,n);</em>

<em />

<em>Where P, T and n are double variables and they must have been initialized</em>

In this project, you will add a (self-proclaimed) priority attribute to xv6 processes. The priority does not actually do anythin
kondor19780726 [428]

Answer:

Priority programming is a process programming method based on priority. In this technique, the developer chooses the tasks to work according to priority, which is different from other types of programming, for example, a simple round-robin.

On UNIX and many other systems, higher priority values represent lower priority processes. Some of the systems, such as Windows, use the opposite convention: a higher number means a higher priority

<h3>Explanation: </h3>

Priorities can be dynamic or static. Static priorities are assigned during creation, while dynamic priorities are assigned according to the behavior of the processes while they are in the system. To illustrate, the planner could favor intensive input / output (I / O) tasks, allowing expensive requests to be issued as soon as possible.

Priorities can be defined internally or externally. Internally defined priorities make use of a measurable amount to calculate the priority of a given process. On the contrary, external priorities are defined using criteria beyond the operating system (OS), which may include the importance of the process, the type and sum of the resources used for the use of the computer, user preferences , trade and other factors such as politics etc.

i hope this is right lol

write a c++ program that reads from the user a positive integer (in a decimal representation), and prints its binary (base 2) re
Vesna [10]

Answer:

The program to this question can be described as follows:

Program:

#include <iostream> //defining header file

using namespace std;

int main() //defining main method

{

int x1,rem,i=1; //defining integer variable

long Num=0;// defining long variable

cout << "Input a decimal number: "; // print message

cin >> x1; //input value by user

while (x1!=0) //loop for calculate binary number

{

//calculating binary value    

rem= x1%2;

x1=x1/2;

Num =Num +rem*i;//holding calculate value

i=i*10;

}

cout <<Num;//print value

return 0;

}

Output:

Input a decimal number: 76

1001100

Explanation:

In the above code, four variable "x1, rem, i, and Num" is declared, in which three "x1, rem, and i" is an integer variable, and one "Num" is a long variable.

  • In the x1 variable, we take input by the user and use the while loop to calculate its binary number.
  • In the loop, first, we check x1 variable value is not equal to 0, inside we calculate it binary number that store in long "Num" variable, after calculating its binary number the print method "cout" is used to prints its value.
