Concept:Computers process all data using binary language, which contains only two digits:
0 and
1.
Explanation:COBOL and BASIC are high-level programming languages used by humans to write programs, not by computers to process data.
Windows is an operating system that provides a user interface, but it does not directly handle data at the hardware level.
A computer's processor (CPU) understands only machine language, which is the binary language.
In binary, every piece of data — numbers, text, images, and instructions — is represented using only
0 and
1.
The digit
0 represents OFF, meaning no electric current flows.
The digit
1 represents ON, meaning electric current is allowed to flow.
These ON and OFF states are physically created using transistors inside the processor.
A sequence of bits (binary digits) forms a binary number, which can be converted into a decimal number for calculations.
Therefore, binary is the only language a computer directly uses to process data and execute instructions.
Answer:The correct answer is Binary (Option D).
