The result of assembling an assembly language source is an executable. The name of that executable is dependent upon the output file name passed to the assembler. The program that performs the assembly is the assembler itself. More specifically, the assembler produces one or more object files, which are fed into the linker or binder. The linker or binder then produces the executable, by combining the object files, along with referenced library files, and then resolving external references.
Assembly langue is translated into machine language by an assembler.
what is the difference between an assembler and the translator
The Assembly B in the same directory it is in
A low-level language is any symbolic computer programming language that has a low-level of abstraction between the language itself and the machine code that it produces. Assembler language has a near 1:1 relationship with its resultant machine code and is therefore a low-level language. In fact, the only things lower than assembler language is machine code itself and disassembly, which is the reverse of assembly, both of which have no abstraction whatsoever. The only real difference between assembler language and disassembly are that disassembly has none of the comments and none of the symbolic references used by the original assembler, since both were stripped out during assembly. However, a competent hacker, with the aid of the disassembler, can reconstruct a facsimile of the original assembler from the machine code disassembly, thus permitting software to be reverse-engineered.
multipass assembler means more than one pass is used by assembler.multipass assembler is used to eliminate forward references in sybol definition.it creates a number of passes that is necessary to process the definition of symbols•Multi pass assembler:-Does the work in two pass-Resolves the forward references•First pass:-Scans the code-Validates the tokens-Creates a symbol table•Second Pass:-Solves forward references-Converts the code to the machine code

A two-pass assembler reads through the source code twice. Each read-through is called a pass. On pass one the assembler doesn't write any code. It builds up a table of symbolic names against values or addresses. On pass two, the assembler generates the output code, using the table to resolve symbolic names, enabling it to enter the correct values. The advantage of a two-pass assember is that it allows forward referencing in the source code because when the assembler is generating code it has already found all references.
One well known and good assembler is NASM. (Netwide ASseMbler). This can be found at http://nasm.sf.net
An assembler which runs on a computer for which it produces object codes
An absolute assembler is a computing term for an assembler which generates code which uses only absolute addresses.
There are several examples of assemblers: GAS - the GNU Assembler MASM - Microsoft Macro Assembler NASM - Netwide Assembler The assembler is the program which converts assembly code into machine code - a necessary step to prepare a program for execution.
Meta-assembler is a program that accepts the syntactic and semantic description of an assembly language, and generates an assembler for that language.

In theory the only advantage is Speed simply because one pass is faster than two passes. However a properly written two pass assembler can be faster than a poorly written one pass assembler because the two pass assembler spends alot less time doing memory intensive lookups, look-aheads, and back-tracking.
list out assembler directive?
