14. Which statement describes machine language?
Answer: A
Code expressed in the binary system
Machine language is fundamentally composed of binary code, which is the most basic form of programming language that a computer can understand and execute directly. This language consists of sequences of 0s and 1s that represent instructions to the computer's hardware.
A) Code expressed in the binary system
This option is correct as it accurately describes machine language, which is indeed represented in binary format. Each instruction in machine language corresponds directly to a specific operation that the computer's processor can perform, making it the lowest-level programming language.
B) Code that can be run one line at a time
This option is incorrect because machine language does not operate on the principle of line-by-line execution like higher-level languages. Instead, it consists of binary code that the computer executes directly without the need for interpretation or compilation in the same manner as line-by-line languages.
C) Code commands that directly access registers
While machine language can include commands that access registers, this option is misleading as it does not fully encompass the definition of machine language. Machine language is broader and is defined by its binary representation rather than solely focused on register access.
D) Computer code that humans can understand
This option is incorrect since machine language is not intended for human comprehension. It is a low-level language designed for machine execution, and humans typically use higher-level programming languages that are more readable and understandable.
Conclusion
The correct answer, "Code expressed in the binary system," accurately captures the essence of machine language, which is defined by its binary format. Other options fail to describe machine language correctly, either misrepresenting its characteristics or focusing on aspects that do not define it comprehensively.
