Answer: (D) Intelligence
Answer: (D) Intelligence
While computers can process vast amounts of data and execute complex algorithms to simulate intelligence (Artificial Intelligence), they do not possess inherent intelligence, intuition, or the ability to think, reason, or make decisions based on emotion or consciousness like humans do. Their "intelligence" is derived from the programs and data they are fed.

Q4. Which of the following computer language is written in binary codes only?
Q4. Which of the following computer language is written in binary codes only?
(A) Assembly Language
(A) Assembly Language
(A) Assembly Language
(B) High-level Language
(B) High-level Language
(B) High-level Language
(C) Machine Language
(C) Machine Language
(C) Machine Language
(D) C
(D) C
(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: (B) Bit
Bit (Binary Digit)
Bit is the smallest unit of data in a computer.
In bynary units of measurement - 4 Bit = 1 Nibble; 8 Bit = 1 Byte; 1024 Byte = 1 Kibibyte (KiB); 1024 Kibibyte = 1 Mebibyte (MiB); 1024 Mebibyte = Gibibyte (GiB); 1024 Gibibyte = 1 Tebibyte (TiB); 1024 Tebibyte = 1 Pebibyte (PiB); and so on.
In decimal units of measurement - 1000 Byte = 1 Kilobyte (KB); 1000 Kilobyte = 1 Megabyte (MB); 1000 Megabyte = Gigabyte (GB); 1000 Gigabyte = 1 Terabyte (TB); 1000 Terabyte = 1 Petabyte (PB); and so on.
