True

All the programming languages mentioned above synchronizes best with contemporary mobile platforms. Corona, for instance, is built on the programming language LUA and is used in the creation of Android mobile apps, primarily games.

Swift on one hand is best for an apple creation (IOS and OSX). Swift is an open source which is extremely easy to learn, and is the future of mobile app development.

On the other hand, scratch is a programming language where children can program and is used as an introductory language. Skills learned from using scratch can be applied to other basic languages like Java and python.

Create a SELECT statement that returns the count, average, max and min of the invoices submitted by each vendor, who has submitt

sveta [45]

Answer:

SELECT Count(order_invoice) as number_of_invoices, Max(order_invoice) as maximum_invoice, Min(order_invoice) as minimum_invoice, Avg(order_invoice) as average_invoice

FROM vendor JOIN invoice ON invoice.id = vendor.id

WHERE order_invoice > 1

ORDER BY number_of_invoices DESC

Explanation:

The select statement of the SQL or structured query language returns twelve rows of four columns from the inner join of the vendor and invoice table in a database where the order_invoice column in the invoice table is greater than one. The result of the query is ordered by the alias column "number_of_invoices" in descending order.

Copy the skeleton of code below into your answer. Then in the space indicated, add your own code to prompt the user for two numb

ahrayia [7]

Answer:

import java.util.*;

public class Main

{

public static void main(String[] args) {

Scanner input = new Scanner(System.in);

System.out.print("Enter the first: ");

int first = input.nextInt();

System.out.print("Enter the second: ");

int second = input.nextInt();

input.nextLine();

System.out.print("Enter your name: ");

String name = input.nextLine();

int difference = Math.abs(second - first);

System.out.println(name + ", the difference is " + difference);

}

Explanation:

*The code is in Java.

Create a Scanner object to get input from the user

Ask the user to enter the first, second, and name

Calculate the difference, subtract the second from the first and then get the absolute value of the result by using Math.abs() method

Print the name and the difference as in required format

Computer A has an overall CPI of 1.3 and can be run at a clock rate of 600 MHz. Computer B has a CPI of 2.5 and can be run at a

kirill115 [55]

Answer:

Check the explanation

Explanation:

CPI means Clock cycle per Instruction

given Clock rate 600 MHz then clock time is Cー 1.67nSec clockrate 600M

Execution time is given by following Formula.

Execution Time(CPU time) = CPI*Instruction Count * clock time = $\frac{CPI*Instruction Count}{ClockRate}$

for system A CPU time is 1.3 * 100, 000 600 106

= 216.67 micro sec.

for system B CPU time is $=\frac{2.5*100,000}{750*10^6}$

= 333.33 micro sec

c) Since the system B is slower than system A, So the system A executes the given program in less time

Hence take CPU execution time of system B as CPU time of System A.

therefore

216.67 micro = = $\frac{2.5*Instruction}{750*10^6}$

Instructions = 216.67*750/2.5

= 65001

hence 65001 instruction are needed for executing program By system B. to complete the program as fast as system A

B, Parallel ports are faster than serial ports.

A parallel port can move a set of 8 bits at a time on eight different wires, it uses a 25 pin connector, called a DB-25 connector, whereas a serial port only has a DB-9 connector.
