An assembler converts assembly language statements into machine language. Assembly language is used almost exclusively by professional programmers to write efficient code and is associated with a specific computer architecture, such as specific Windows computers, specific Apple computers, a particular type of mainframe, a specific supercomputer, or a specific type of mobile device. An assembler works like a compiler, producing object code. However, instead of being associated with a specific programming language, it is used with a specific assembly language and, consequently, with a specific computer architecture.
