Chapter 1: Problem 4

What is the difference between a machine-language program and a highlevel language program?

Short Answer

Expert verified

Answer: The main differences between a machine-language program and a high-level language program are the level of abstraction, readability, portability, and their execution process. Machine-language programs are low-level, hardware-specific, and directly executable by the processor, while high-level language programs are human-readable, platform-independent, and require a compiler or interpreter for execution.

Step by step solution

Definition of Machine Language Programs

Machine-language programs are sequences of binary code (e.g., 0s and 1s) which represent specific instructions that a computer's processor can execute directly. Machine language is considered as a low-level programming language because it is very close to the hardware and is specific to a particular computer architecture.

Definition of High-Level Language Programs

High-level language programs are written in human-readable programming languages such as Python, Java, C++, etc. These languages are designed to be understood and used by humans to express complex algorithms and logic more easily. High-level languages are generally platform-independent, meaning that the same code can be run on different types of computer architectures.

Compilation and Interpretation

One of the key differences between machine-language programs and high-level language programs is their execution process. High-level language programs require a compiler or interpreter to convert the human-readable code into machine language before it can be executed by the computer. This conversion process involves converting high-level language syntax, structures, and abstractions into a series of lower-level machine code instructions.

Abstraction and Readability

High-level languages provide greater abstraction from the hardware, making it easier for programmers to write complex programs without needing to deal with low-level details of the computer architecture. High-level languages typically include features such as variables, control structures, and data structures that make them more readable and maintainable than machine-language programs.

Portability

High-level language programs are more portable when compared to machine-language programs. Due to their platform-independent nature, high-level language programs can be run on different types of computers with minimal changes to the source code. In contrast, machine-language programs are specific to a particular computer architecture and would require a complete rewrite to be executed on another type of hardware.

Conclusion

In summary, the main differences between a machine-language program and a high-level language program are the level of abstraction, readability, portability, and their execution process. Machine-language programs are low-level, hardware-specific, and can be executed directly by the processor. High-level language programs are human-readable, platform-independent, and require a compiler or interpreter to convert the code into machine language before execution by the computer.
