2. Machine language instructions are written in just 0s and 1s.

True

False

Machine language instructions are written in just 0s and 1s because computers can only understand and execute instructions that are in binary format. In machine language, each instruction is represented by a sequence of 0s and 1s, where each digit represents a specific operation or data. This binary representation allows the computer's hardware to directly interpret and execute the instructions, making it the lowest-level programming language.
