What is the print() function in Python and how is it used? Define problem-solving and list tools used to solve problems. Name two parts of a computer and define an algorithm.

Here are the answers to your questions:

1. To display "Hello World" on the computer screen using Python, you use the print() function.

   print("Hello World")
   

   Copy

   The output on the screen will be:

   Hello World
   

   Copy

2. Problem-solving is the process of identifying a problem, analyzing its nature, developing potential solutions, implementing the chosen solution, and evaluating its effectiveness to achieve a desired goal.

3. A common tool used to solve problems, especially in a computing context, is an algorithm. Other tools include flowcharts and pseudocode for planning, and programming languages for implementation.

4. Two parts of a computer are:

   • Central Processing Unit (CPU)
   • Random Access Memory (RAM)

5. In computing, the steps you take in solving a problem are collectively called an algorithm.
