Ideally, you should back up the data on your computer regularly, and the frequency of backups will depend on the amount and importance of the data you generate or modify.

What is backup?

Backup refers to the process of creating a copy of data and storing it in a separate location or device in case the original data is lost, damaged, or corrupted.

Ideally, you should back up your computer's data on a regular basis, with the frequency of backups determined by the amount and importance of the data you generate or modify.

It is recommended to back up critical data, such as important documents, financial records, and photos, at least once a day, and even more frequently if possible, such as hourly or in real-time.

Monthly or weekly backups may be sufficient for less critical data. The key is to have a consistent and dependable backup system in place to safeguard your data in the event of hardware failure, theft, loss, or other disasters.

Thus, this way, the data should be backed up regularly.

Precomputation in algorithms refers to the act of running an initial computation ahead of run time to create a lookup table that may be used by an algorithm to avoid running the same computation repeatedly each time it is executed.

What is algorithm?

An algorithm is a process used to carry out a computation or solve a problem. In either hardware-based or software-based routines, algorithms function as a detailed sequence of instructions that carry out predetermined operations sequentially.

Algorithms are procedures for resolving issues or carrying out tasks. Algorithms include math equations and recipes.

Algorithms are used in programming. All online searching is done using algorithms, which power the internet.

The term "precomputation" in the context of algorithms refers to the act of performing an initial computation before the algorithm is actually used.

This creates a lookup table that the algorithm can utilise to avoid performing the same computation repeatedly each time it is used.

Thus, this way, precomputed tables are essential.

Write a program that accepts a number as input, and prints just the decimal portion. Your program should also work if a negative number is inputted by the user.

Enter a number: 15.789
Sample Output
0.789

Can someone please help me with this because I’m so stuck

Answers

The code is in Java.

It calculates the decimal portion of a number by subtracting the integer portion from the number. It also uses if structure to check if the number is a negative one.

Comments are used to explain each line of code.

//Main.java

import java.util.Scanner;

public class Main

{

public static void main(String[] args) {

 //Initialize the Scanner object to be able to get input

 Scanner input = new Scanner(System.in);

 

 //Declare the variables

 double number, decimalPortion;

 

 //Ask the user to enter a number

 System.out.print("Enter a number: ");

 number = input.nextDouble();

 

 //Get the decimal portion of the number by subtracting the integer part from the number

 decimalPortion = number - (int) number;

 

 //If the number is negative one, multiply the decimal portion with -1 to convert it to a positive value

 if(number < 0)

     decimalPortion *= -1;

 

 //Print the decimal portion

 System.out.println(decimalPortion);

Answers

Answer:

A. Invention of microprocessor

Explanation:

The third generation of computer itself was based on the technology of integrated circuits (shorten as IC).

It lasted for about 6 years and was brought to an end with the advent of the fourth generation of computers which was based on microprocessors.

Hence, option A answers the question.

Answer: I'm pretty sure the answer is C. Integrated Circuits.

Explanation: "The computers of the third generation used Integrated Circuits (ICs) in place of transistors. A single IC has many transistors, resistors, and capacitors along with the associated circuitry. The IC was invented by Jack Kilby. This development made computers smaller in size, reliable, and efficient." ( Tutorialspointwww.tutorialspoint.com)
