What is the term for the machine code language that computers use?

The correct term for the machine code language that computers use is low-level language. Low-level languages are fundamentally closest to the hardware and are often referred to as machine languages or assembly languages. These languages provide a way for programmers to write instructions that the computer's hardware can understand directly.

Machine code is a binary representation of the instructions that a computer's CPU executes, consisting of 1s and 0s. Low-level languages allow for efficient manipulation of hardware resources and have a direct correlation to the architecture of the physical machine.

High-level languages, in contrast, are designed to be more easily understandable and user-friendly, allowing developers to write instructions without needing to manage the specifics of the hardware. Assembly language is a specific type of low-level language that uses mnemonics and symbols to represent machine code instructions, but it is not the same as machine code itself. Script languages typically provide a higher level of abstraction and facilitate automation of tasks without the need for detailed memory management that low-level languages require.
