ing to Wikipedia, the first assembly language, "Contracted Notation", was developed in 1947 by the late Kathleen Booth (née Britten). The language doesn't look anything like “modern” assembly though (see the end of this paper); it's more a mathematical representation of computer operations.

Assembly is basically binary code written in a form that humans can read. The assembler then takes the assembly code and translates it line by line to the corresponding bit code. That being said assemblers also have extra functionality like macros etc. but the main functionality is that described above.

Linking is a process of collecting and maintaining piece of code and data into a single file. Linker also links a particular module into system library. It takes object modules from assembler as input and forms an executable file as output for the loader.

Assembly language uses a mnemonic to represent, e.g., each low-level machine instruction or opcode, each directive, typically also each architectural register, flag, etc. Some of the mnemonics may be built in and some user defined. Many operations require one or more operands in order to form a complete instruction.

The first assemblers were probably written in assembly language and then hand assembled into machine code. Even if the processor had no official 'assembly language' then programmers probably did most of the job of programming using some kind of pseudo code before translating that code into machine instructions.

The difference between compiler and assembler is that a compiler is used to convert high-level programming language code into machine language code. On the other hand, an assembler converts assembly level language code into machine language code. Both these terms are relevant in context to program execution.

When the cc command is used to assemble and link source files, any assembler source files must have the suffix of . s. The cc command invokes the assembler for any files having this suffix. Option flags for the as command can be directed to the assembler through the cc command.

The Assembler is a Software that converts an assembly language code to machine code. It takes basic Computer commands and converts them into Binary Code that Computer's Processor can use to perform its Basic Operations. These instructions are assembler language or assembly language.
