(A) Assembly Language

(D) C
Answer: (C) Machine Language
Answer: (C) Machine Language
Answer: (C) Machine Language
Machine language is the only computer language that is directly written and understood in binary codes (sequences of 0s and 1s). It is the lowest-level programming language and is specific to the computer's architecture. Every instruction that the CPU executes is in machine code. Assembly language uses mnemonics to represent machine code instructions, making it slightly more human-readable than raw binary, but it still requires an assembler to translate it into machine code. High-level languages are much more abstract and human-readable, requiring compilers or interpreters to translate them into machine code before execution.

Answer: (D) Design code
Answer: (D) Design code
Computer code refers to the instructions that a computer can understand and execute. Source code is human-readable code written by programmers using a high-level programming language (e.g., Python, Java, C++).Object code is the output of a compiler after translating source code into machine-readable instructions, but it's not yet executable on its own and often needs to be linked with other object files. Machine code is the lowest-level programming language, directly executable by a computer's CPU. It consists of binary instructions (0s and 1s).Bytecode is an intermediate form of code that is typically executed by a virtual machine (like the Java Virtual Machine). It's platform-independent.

Answer: (C) HTML
HTML (HyperText Markup Language) is the fundamental language used to create the structure and content of a web page. While CSS is essential for styling and JavaScript adds interactivity, HTML is the core language that defines the basic building blocks of a website, such as headings, paragraphs, images, and links. Without HTML, you wouldn't have a web page to style or add interactivity to.
