Word.py

A file extension used for Python script files, indicating that the file contains Python code.

Assembler

A specialized program that converts instructions written in assembly language into machine code, which the computer's processor understands.

Assembly Language

A low-level programming language that uses mnemonics (short codes) to represent instructions for a computer's processor. It's closer to machine language than high-level languages.

Bit

The smallest unit of data in computing, representing a binary value 0 or 1, like a light switch that's either on or off.
