How Much Memory Did the First Computers Have?

ENIAC, the first general purpose computer, only had 20 10-digit accumulators; since a decimal digit is somewhere above 3 bits, you have somewhere above 600 bits, or 75 bytes of memory.

Other machines I don't classify as computers... at all :)

Your task is to design a method int[] allMatches(int[] values, int size, int a, int b) that returns all values between a and b i
iogann1982 [59]

The program that returns all values between a and b inclusive in the partially filled array values is illustrated below.

<h3>What is a program?</h3>

A computer program means a sequence or set of instructions that is in a programming language for a computer to execute.

Here, the program based on the information given will be:

count = 0

for each v in values

if a <= v <= b

 count++

result = new int[count]

i = 0

for each v in values

if a <= v <= b

 result[i] = v

 i++

return result

Java code:

public class ArrayRange {

public static int[] allMatches(int[] values, int size, int a, int b) {

 int count = 0;

 for (int i = 0; i < size; i++) {

  if(values[i] >= a && values[i] <= b) {

   count++;

  }

 }

 int result[] = new int[count];

 count = 0;

 for (int i = 0; i < size; i++) {

  if(values[i] >= a && values[i] <= b) {

   result[count++] = values[i];

  }

 }

 return result;

}

public static void main(String[] args) {

 int[] a = {11, 3, 9, 4, 2, 5, 4, 7, 6, 0};

 int[] returnedArray = allMatches(a, 8, 3, 7);

 for (int i = 0; i < returnedArray.length; i++) {

  System.out.print(returnedArray[i] + " "

kondaur [170]

The discipline of building hardware architectures, operating systems, and specialized algorithms for running a program on a cluster of processors is known as <u>parallel computing.</u>

<u></u>

<h3>What is Parallel Computing?</h3>

Parallel computing refers to the process of breaking down larger problems into smaller, independent, often similar parts that can be executed simultaneously by multiple processors communicating via shared memory, the results of which are combined upon completion as part of an overall algorithm. The primary goal of parallel computing is to increase available computation power for faster application processing and problem solving.

<h3>Types of parallel computing</h3>

There are generally four types of parallel computing, available from both proprietary and open source parallel computing vendors:

  • Bit-level parallelism: increases processor word size, which reduces the quantity of instructions the processor must execute in order to perform an operation on variables greater than the length of the word.
  • Instruction-level parallelism: the hardware approach works upon dynamic parallelism, in which the processor decides at run-time which instructions to execute in parallel; the software approach works upon static parallelism, in which the compiler decides which instructions to execute in parallel.
  • Task parallelism: a form of parallelization of computer code across multiple processors that runs several different tasks at the same time on the same data.
  • Superword-level parallelism: a vectorization technique that can exploit parallelism of inline code.

Write a modular program that allows the user to enter a word or phrase and determines whether the word or phrase is a palindrome
Ostrovityanka [42]

Answer:

import java.util.Scanner;

public class num10 {

   public static void main(String[] args) {

       Scanner in = new Scanner(System.in);

       System.out.println("Enter a word");

       String word = in.nextLine();

       String reversed = "";

       //Get the length of the string entered

       int length = word.length();

       //Loop through the string and reverse th string

       for ( int i = length - 1; i >= 0; i-- )

           reversed = reversed + word.charAt(i);

       //Compare the two strings "word" and "reversed"

       if (word.equals(reversed))

           System.out.println(word+" is a palindrome");

       else

           System.out.println(word+" is not a palindrome");

   }

}

Explanation:

Since we know that a palindrome word is a word that reads the same forward and backward, The Idea here is:

  • To obtain a word from a user.  
  • Use a for loop to reverse the word and store in another variable
  • Use if....else to compare the two strings and determine if they are equal, if they are equal then the word is palindrome.
