Goshia [24]

Using the knowledge in computational language in JAVA it is possible to write a code that organizes and synchronizes the programs that will run on the computer.

<h3>Writting the JAVA code as:</h3>

import java.util.concurrent.ExecutorService;

import java.util.concurrent.Executors;

public class Main

{

Integer sum=new Integer(0);

Main(){

ExecutorService e=Executors.newFixedThreadPool(1000);

final Sum s = new Sum();

for(int i=0;i<1000;i++){

e.execute(s);

}

e.shutdown();

while(!e.isTerminated()){

}

System.out.println(sum);

}

public static void main(String[]args){

new Main();

}

class Sum implements Runnable{

public void run() {

m();

}

public void m(){

sum=sum+1;

}

Which biometric technique is considered nearly infallible from a scientific point of view and is increasingly preferred by crimi

Sergio039 [100]

Answer:

DNA analysis

Explanation:

DNA is unique for all individuals. DNA analysis is the process of analysing the DNA characteristics of an individual.

DNA profiling is used in forensics to identify the suspects involved in criminal activities.

1. In the process, DNA of the suspects is matched with the DNA found in the site of the crime.

2. If a match is found, it indicates that the genetic relationship exists between the suspect and the criminal or the crim.

3. The order from the court is needed to obtain the DNA of the suspects. The sample can be in the form of blood or saliva.

4. The sample obtained should have adequate cells which contain the DNA.

Issues

The DNA obtained from the crime site is not pure or proper enough to be ideal for the DNA profiling.

Degraded sample

1. The sample obtained from the site of the crime is not always adequate to obtain the actual DNA.

2. The sample can be contaminated due to the environmental factors.

3. The sample obtained is too less and hence, should be examined accurately in order not to waste the sample.

DNA mixture

4. The sample obtained from the site of the crime is found to contain DNA from more than one individual.

Profiling types

DNA profiling can be carried out by using any of the techniques mentioned below.

1. RFLP analysis ( Restriction fragment length polymorphism )

This uses the Southern blot technique. The blot process needs a large amount of the sample. Also, this works well only when the sample is not degraded.

2. Polymerase chain reaction (PCR) analysis

3. STR analysis ( short tandem repeats )

4. AFLP ( amplified fragment length polymorphism )

This is an automated and low-cost process. It is easy to set up and operate which makes this process common in low income countries.

All the methods mentioned above have their own advantages and drawbacks.

How have newspapers and magazines adapted to digital technology?

Ahat [919]

Answer:

Most newspapers now have online editions. Subscription models have gone beyond print-only into digital-only and print-digital combinations -- and as print-only circulation is dropping, digital and combination circulation is on the rise.

Write a Python program to balance a checkbook. The main function needs to get the initial balance, the amounts of deposits, and

Irina18 [472]

Answer:

def deposit(deposit_amount, balance):

balance += deposit_amount

return balance;

def process_check(check_amount, balance):

balance -= check_amount

return balance;

balance = float(input("Enter the initial balance: "))

transaction = input("Choose transaction method - D to deposit, C to process check, Q to quit: ")

while transaction != 'Q':

if transaction == 'D':

deposit_amount = float(input("Enter amount to be deposited: "))

balance = deposit(deposit_amount, balance)

print("Current balance is: " + str(balance))

elif transaction == 'C':

check_amount = float(input("Enter amount to process check: "))

if balance >= check_amount:

balance = process_check(check_amount, balance)

print("Current balance is: " + str(balance))

else:

print("Not enough money!")

else:

print("Invalid input!")

transaction = input("Choose transaction method - D to deposit, C to process the check, Q to quit: ")

print("Your final balance is: " + str(balance))

Explanation:

- Create functions to handle deposits and checks

- Ask the user for the initial balance and transaction to be made

- Initialize a while loop iterates until the user enter Q

- Ask the deposit amount or check amount depending on the transaction chosen

- Calculate and print the current balance for each transaction

- Print the final balance

What does a compiler do, and why is it necessary when using higher-level languages?

UkoKoshka [18]

Answer:

A compiler converts human readable instructions into machine code (machine readable instructions). Without it, a computer will not be able to understand the code that was written and execute it. Since higher programmer languages are easier for humans to read and write and effective compiler is needed. This has to do with how the compiler does much of the work when it comes to programming.

A great example is a drag and drop programming language. The compiler does all the work in the background before the machine can actually execute the code, but the language itself is incredibly easy to read and write by human standards. Without the compiler, it would be impossible for the machine to execute any code.

Explanation:

High Level programming languages like Python has a system that turns our easy to read human code into something the computer can actually read. Python for example, doesn't compile the code as it was design to do it as it runs.

Low level programming languages like Objective C uses a compiler to change the human readable code to machine code. You can tell a compiler was used when there is a 2nd file, one that can't be read by humans. This is the compiled code that the machine actually runs.
