Which description best fits a language that is close to machine code and typically harder for humans to read?

• A. Low-level language
• B. High-level language
• C. Truth table
• D. Logic circuit

Answer: (A)

A language that is close to machine code sits at a low level of abstraction. Low-level languages translate almost directly into the instructions a computer’s processor executes, often requiring detailed management of memory and hardware-specific details. This proximity to the hardware gives programmers precise control and potential performance benefits, but it also makes the code harder for humans to read and understand compared with higher-level languages, which use more natural syntax and abstractions like loops, functions, and data structures. High-level languages are designed to be readable and portable, relying on compilers or interpreters to convert them into machine code. Truth tables and logic circuits aren’t programming languages for writing instructions; truth tables represent boolean logic, and logic circuits are hardware implementations of that logic. So the description that fits best is low-level language.
