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.

The word "COMPUTER" is not an abbreviation itself, but rather a standalone word derived from the verb "compute." While some informal or contextual shortenings like "comp" might be used, there is no universally recognized or official abbreviation for "COMPUTER" in the same way that there are for terms like "e.g." or "Dr." Attempts to create an acronym for "COMPUTER" (e.g., "Common Operating Machine Purposely Used for Technical and Educational Research") are generally considered backronyms and not the origin or a true abbreviation of the word.

Answer: (B) Central Processing Unit
CPU stands for Central Processing Unit. It is often referred to as the "brain" of the computer because it is the primary component that performs most of the processing inside a computer. Its main function is to execute instructions, perform arithmetic and logical operations, and manage the overall flow of data and instructions within the computer system.
