CSE Final Review

1. What is abstraction?

• The process of performing calculations or carrying out commands on a computer
• In computer science, an algorithm is a set of instructions that a computer follows to complete a task or solve a problem
• The process of removing unnecessary or distracting elements from a program or code. It involves focusing on the general meaning or form of something while reducing the number of specific details.
• A number that is not a fraction; a whole number.

2. In MIT App Inventor, a control block that looks for inputs or events to know when to perform a specific action.

• Event Handler
• Variable
• String
• While Loop

3. Information or signals entered into a computer system. Examples of input devices are buttons, keys on a keyboard, touch screens, and accelerometers.

• output
• input

4. Information or signals produced or delivered by a computer system.

• output
• input

5. To identify errors or bugs in computer hardware or programs and fix them.

• Computation
• Abstraction
• Research
• Debugging

6. A process of repeating a set of instructions a specified number of times or until a condition is met, such as in a repetition of a process or a newer version of development in computer science.

• Iteration
• Abstraction
• Debugging
• Event Handler

7. An Argument is ...

• A storage location for data
• A value that is passed to a storage location to be used by the program

8. A variable is ...

• A storage location for data
• A value that gets passed to a storage location to be used by the program

9. A joining together of separate items—without changing them—into one place. For example, the concatenation of two strings such as “Hello” and “world!” would return “Hello world!”

• Iteration
• Concatenation
• Abstraction
• Event Handler

10. A process or set of rules to be followed in calculations or other problem-solving operations, especially by a computer.

• Algorithm
• Iteration
• Abstraction
• Debugging
