What language do computers understand
- A.
Denary
- B.
Binary
- C.
English
- D.
Spanglish
Correct Answer
B. BinaryExplanation
Computers understand the language of binary. Binary is a base-2 number system that uses only two digits, 0 and 1, to represent all information. Computers use electrical signals to represent these binary digits, with 0 representing off and 1 representing on. This binary language allows computers to process and store data in a way that can be easily understood by their electronic components. Other languages like denary and English are not directly understood by computers and need to be converted into binary for processing. Spanglish is a mix of Spanish and English and is not a language that computers understand.Rate this question:
