COMPUTER LANGUAGES Week 6

What is machine code and how is it used?

• Machine code is a graphical representation of computer programs.

• Machine code is a high-level programming language used for web development.

• Machine code is a type of software that runs on mobile devices.

• Machine code is used to perform operations directly on the hardware of a computer, enabling the execution of programs.

Explain the role of assembly language in programming.

• Assembly language is only relevant for mobile app development.

• Assembly language is primarily used for web development.

• Assembly language plays a crucial role in programming by providing a low-level interface to hardware, enabling precise control over system resources and performance.

• Assembly language is a high-level programming language.

What are the main characteristics of high-level languages?

• Direct hardware manipulation

• Limited support for complex data structures

• Strict syntax with no flexibility

• Main characteristics of high-level languages include abstraction from hardware, ease of use, readability, strong typing, automatic memory management, and support for complex data structures.

How does low-level language differ from high-level language?

• Low-level languages are easier to learn than high-level languages.

• Low-level languages are hardware-oriented and less abstract, while high-level languages are user-friendly and more abstract.

• Low-level languages are primarily used for web development.

• High-level languages are more efficient in terms of memory usage.

What is the purpose of writing software in assembly language?

• The purpose of writing software in assembly language is to achieve low-level control and optimization for performance.

• To simplify the coding process for beginners.

• To create user-friendly graphical interfaces.

• To write software that is easily portable across different platforms.

Describe the advantages of using high-level languages over low-level languages.

• High-level languages are easier to read, write, and maintain, offer better portability, and enhance developer productivity.

• Low-level languages are more user-friendly and intuitive.

• High-level languages require more memory and processing power.

• High-level languages are less portable and harder to maintain.

What is the relationship between machine code and assembly language?

• Assembly language is only used for web development.

• Assembly language is a type of machine code.

• Machine code is a higher-level language than assembly.

• Assembly language is a human-readable representation of machine code.

How do compilers and interpreters relate to high-level languages?

• Compilers translate high-level languages into machine code, while interpreters execute high-level languages directly.

• Compilers execute high-level languages directly, while interpreters translate them into machine code.

• Compilers and interpreters are both types of high-level languages.

• Interpreters convert machine code into high-level languages.

What are some examples of low-level programming languages?

• Java

• Python

• C++

• Assembly language, Machine code

Why is machine code considered the most basic form of programming?

• Machine code is written in high-level languages.

• Machine code is a type of software application.

• Machine code is considered the most basic form of programming because it consists of binary instructions that the CPU can directly execute.

• Machine code is only used for debugging purposes.
