An assembler is a program that translates assembly code into machine code that the computer can execute directly.
The assembler takes the assembly code written in a file (usually with the extension .asm) and converts it into an object file (usually with the extension .o) containing the machine code.
Assembly refers to the low-level programming language that uses symbolic instructions to represent operations to be executed directly on the CPU.
Assembly code is written in a file (usually with the extension .asm) and is used to directly program the CPU.
The assembler is the program that translates the assembly code into machine code.
Assembly is the programming language used to write the code that will be translated into machine code.
The .asm file is the file that contains the assembly code that was written using the assembly language.
