Coding(10.1.7 Lesson Review)

Question 1

What makes it easier for humans to read and write instructions for computers?

Answer 1

Programming languages

Explanation

Programming languages are designed to be more understandable for humans, making it easier to write instructions for computers.

Machine language is difficult for humans to understand.

Binary code is the same as machine language and is hard for humans to read.

Hardware refers to the physical components of a computer, not the languages used to program it.

Question 2

What does the term “syntax” refer to in computer programming?

Answer 2

The rules for how to write the language.

Explanation

Syntax refers to the set of rules that define the structure and composition of statements in a programming language.

Syntax does not relate to the speed of a program.

Syntax is not related to the type of computer.

Syntax has nothing to do with the color scheme of the code editor.

Question 3

What is a programming language?

Answer 3

A set of instructions programmers use to write code.

Explanation

A programming language provides a set of instructions and rules that allow programmers to write code that a computer can understand and execute.

These instructions form the basis of software development, enabling the creation of applications, websites, and other digital solutions.

Computer hardware does not involve the instructions or rules used to write code.

A programming language itself is not solely a method for designing websites.

It is a broader concept used for various types of software development.

Programming languages are not responsible for facilitating communication among programmers.

Question 4

What is the main purpose of query languages?

Answer 4

To get information from databases

Explanation

Query languages, like SQL, are specifically designed to retrieve and manipulate data stored in databases.

Creating websites typically involves languages like HTML, CSS, and JavaScript, not query languages.

Designing computer games usually involves programming languages like C++, Java, or specialized game development tools.

Writing stories does not involve query languages.

Question 5

What is an interpreted language?

Answer 5

A language that runs instructions in the source code whenever you run the application

Explanation

Interpreted languages run the instructions in the source code whenever you run the application.

A language that converts source code into binary ahead of time describes a compiled language.

Interpreted languages can be used for various types of development, not just web development.

Interpreted languages are platform-independent, meaning they can be used on multiple platforms.

Question 6

What is one advantage of interpreted languages?

Answer 6

They are platform-independent.

Explanation

Interpreted languages are platform-independent, meaning they can run on different operating systems without changing the source code.

Interpreted languages are generally slower than compiled languages.

Having limited access to system resources is a disadvantage.

Turning source code into binary ahead of time describes compiled languages.

Question 7

Why are compiled languages often used for resource-intensive programs like high-end video games?

Answer 7

Because they run quickly and efficiently

Explanation

Compiled languages are used for resource-intensive programs because the compiled code runs quickly and efficiently, making it suitable for demanding applications like high-end video games.

Compiled languages are not necessarily easier to write.

Compiled languages are not interpreted line by line.

Compiled languages need to be ported to run on different types of computers, but this is not the reason they are used for resource-intensive programs.

Question 8

What is a runtime engine?

Answer 8

A tool that interprets bytecode into the computer’s specific machine language

Explanation

A runtime engine is a tool that interprets bytecode into the computer’s specific machine language, allowing the program to run on the computer.

A runtime engine does not compile code; it interprets bytecode.

A runtime engine is not a high-level programming language.

A runtime engine is not a device used to run video games.

Question 9

What is the main purpose of a compiler in compiled programming languages?

Answer 9

To convert the code into machine language

Explanation

A compiler’s main purpose is to convert the code written by the programmer into machine language, which is a format that the computer’s processor can understand and execute directly.

Code cannot be executed directly without being converted into machine language first.

To interpret the code line by line during execution describes the function of an interpreter.

Compilers do not save the code as a text file; they save it as a binary executable file.

Question 10

Why is code written in assembly language more efficient?

Answer 10

It allows direct access to hardware.

Explanation

Assembly language is more efficient because it allows direct access to the hardware.

Assembly language does not use a compiler.

Assembly language is not written in binary; it is a human-readable form of machine code.

Assembly language is a low-level language.
