What are the three main purposes of an operating system? Explain how the old mainframe computers were different from the compute

lbvjy [14]

Answer:(1) To manage the computer's resources, which includes central processing unit, memory, disk drives, and printers, (2) To establish a user interface

(3)To execute and provide services for applications software.

The old mainframe computers have

(1) low memory sizes

(2) slower connectivity speed

(3) Larger sizer

(4) low sophistication.

Explanation: Operating system is a system software that manages the computer resources,helps to establish user interface and it helps to provide services for application softwares.

Operating system software includes WINDOWS X,WINDOWS 7,WINDOWS 8,LINUX,etc.

Mainframe computers are computers used by large multinational companies for processing bulk data. Old mainframe computers were produced by IBM(INTERNATIONAL BUSINESS MACHINE) in the year 1952 they are classed two scientific and commercial mainframe computers with different information although they had some incompatibilities. Old mainframe computers are large in size with low processing speed, sophistication and storage compared to present day system.

What is the initial condition in this set of code?

marissa [1.9K]

Answer:An initial condition is an extra bit of information about a differential equation that tells you the value of the function at a particular point. Differential equations with initial conditions are commonly called initial value problems.

The video above uses the example

{

d

y

d

x

=

cos

(

x

)

y

(

0

)

=

−

1

to illustrate a simple initial value problem. Solving the differential equation without the initial condition gives you

y

=

sin

(

x

)

+

C

.

Once you get the general solution, you can use the initial value to find a particular solution which satisfies the problem. In this case, plugging in

0

for

x

and

−

1

for

y

gives us

−

1

=

C

, meaning that the particular solution must be

y

=

sin

(

x

)

−

1

.

So the general way to solve initial value problems is: - First, find the general solution while ignoring the initial condition. - Then, use the initial condition to plug in values and find a particular solution.

Two additional things to keep in mind: First, the initial value doesn't necessarily have to just be

y

-values. Higher-order equations might have an initial value for both

y

and

y

′

, for example.

Second, an initial value problem doesn't always have a unique solution. It's possible for an initial value problem to have multiple solutions, or even no solution at all.

DLucy is planning to launch her podcast on career guidance for college students and has already recorded a few videos for market

KIM [24]

Answer:

A. FilmoraGo; C. Adobe Premiere

Explanation:

Many video editing software exists out there, but their function is pretty much the same. They edit, mix and customize clips to create beautiful multimedia content for different purposes (advertisements, podcasts, movies, comedy clips, etc.). This software used are different as some may contain more functions and setting than the other.

Let us take a brief dive into the options:

FilmoraGo: is a video editing software that runs on Andriod and iOS. It contains many effects and it is pretty basic to use and understand.
Google Photos: Created by Google, helps to organize your photo albums and stores them for you.
Adobe Premiere: is also a video editing software, it was first launched in 2003 and has since evolved to contain more sophisticated video editing tools.
Audacity: is an audio editor available for Windows, Mac OS, and Linux. This software is completely free and open source.

Hence, dLucy can use the FilmoraGo or the Adobe Premiere to edit her video clips.

The insertion sort algorithm sorts using what technique?

QveST [7]

Answer:

Iteration

Explanation:

The insertion sort is based on repetition of comparing one data array (or element in a list) with the others at its left to reorganize it, normally following a size criteria (from small to big or the other way around).

At each iteration, the algorithm takes one element and compares it one by one to the others until it fit the specified criteria. Later on, it creates a space, moving the other elements, to insert it. Later, it goes to the next element and the iteration repeats all the way through. It has some advantages over other sorting algorithms because it is easy to deploy and program it in many different languages, but at the same time it can be terribly slow when sorting large amount of data.

1.Write a Java program to solve the following problem using modularity. Write a method that rotates a one-dimensional array with

Westkost [7]

Answer:

Explanation:

The following code is written in Java and it asks the user for the size of the array. Then it randomly populates the array and prints it. Next, it rotates all the elements to the right by 1 and prints the new rotated array.

import java.util.ArrayList;

import java.util.Arrays;

import java.util.Random;

import java.util.Scanner;

class Brainly {

public static void main(String[] args) {

Random r = new Random();

Scanner in = new Scanner(System.in);

System.out.println("Enter Size of the Array: ");

int arraySize = in.nextInt();

ArrayList<Integer> myList = new ArrayList<>();

for (int x = 0; x < arraySize; x++) {

myList.add(r.nextInt(15));

}

System.out.println("List Before Rotation : " + Arrays.toString(myList.toArray()));

for (int i = 0; i < 1; i++) {

int temp = myList.get(myList.size()-1);

for (int j = myList.size()-1; j > 0; j--) {

myList.set(j, myList.get(j - 1));

}

myList.set(0, temp);

}

System.out.println("List After Rotation : " + Arrays.toString(myList.toArray()));

}
