In assembly program, the code, data and stack are structures as program segments. Each segment is translated into a memory segment by the assembler. The size of the code and data a program can have is determined by specifying a memory model using . MODEL directive.

But on the other hand, assembly language uses mnemonics or symbolic instructions in place of a sequence of 0s and 1s. As example, we can consider that, to add register A and B in a particular computer, assembly language uses the mnemonic 'ADD B' in place of 10001111.

An assembly language statement consists of four possible fields: a label field, a mnemonic field, an operand field, and a comment file. The mnemonic and comment fields are always optional. The label field is generally optional although certain instructions (mnemonics) do not allow labels while others require labels.

An assembly language statement is a line of text that translates into a single machine instruction. Assembly Language is expressed in a more human readable form than the binary instructions and names are allowed for memory locations, registers, operations etc. For example: ADD [result],[coursework],[exam]

In computer programming an assembly is a runtime unit consisting of types and other resources. All types in an assembly have the same version number. Often, one assembly has only one namespace and is used by one program. But it can span over several namespaces. Also, one namespace can spread over several assemblies.

Example of assembly language The "MOV" is the mnemonic command to move the number "3" into a part of the computer processor, which can function as a variable. "EAX," "EBX" and "ECX" are the variables. The first line of code loads "3" into the register "eax." The second line of code loads "4" into the register "ebx."

The file extension of the assembly program is ". asm" for the Code Warrior assembler, but is often ". s" for other assemblers. The assembly code is called source code and the assembly program file is usually called a source file.

Assembly language was created as an exact shorthand for machine level coding, so that you wouldn't have to count 0s and 1s all day.Today, assembly language is used primarily for direct hardware manipulation, access to specialized processor instructions, or to address critical performance issues.

It produces a machine code in form of mnemonics. It produces binary code in form of 0s and 1s. Examples are Java, C, C++ etc. compilers. Examples of assemblers are GAS, GNU etc.

Use the LTORG instruction so that the assembler can collect and assemble literals into a literal pool. A literal pool contains the literals you specify in a source module either after the preceding LTORG instruction, or after the beginning of the source module.
