Concept:Machine language is the lowest-level programming language that a computer's hardware can directly execute.
Explanation:A computer's central processing unit (CPU) understands only electronic signals represented as two states: on and off.
These two states are written as the binary digits
0 and
1.
Every machine language instruction code is made of a sequence of these bits, such as
10110011.
This binary sequence tells the processor which operation to perform and which data to use.
Other codes like hexadecimal, ASCII, and EBCDIC are human-readable representations or character encodings, not the direct instruction format of the machine.
Answer:D. binary
