Where can you get an assembler?
One well known and good assembler is NASM. (Netwide ASseMbler). This can be found at http://nasm.sf.net
What is an absolute loader?
An absolute loader is the simplest type of loader scheme that fits the general model of loaders. The assembler produces the output in the same way as in the "complier and go loader" . The assembler outputs the machine language translation of the source program.Disadvantage:The programmer has to specify the address to the assembler that where the program is to be loaded.It is very difficult to realocate in case of multiple subroutine.Programmer has to remember the address of each subroutine and use that absolute address explicitly in other subroutines to perform subroutine linkage
What is masm?
it means Microsoft Macro Assembler
Describe some of the tasks that an assembler needs to perform?
The task that the Assembler needs to be perform among of these are....- the assembler takes its source code as assembly language program.- making direct hardware access for device driver.- produce machine code.
What is the Design of single pass assembler?
Single Pass Assembler A single pass assembler scans the program only once and creates the equivalent binary program. The assembler substitute all of the symbolic instruction with machine code in one pass. AdvantagesEvery source statement needs to be processed once.DisadvantagesWe cannot use any forward reference in our program. Forward ReferenceForward reference means; reference to an instruction which has not yet been encountered by the assembler. In order to handle forward reference, the program needs to be scanned twice. In other words a two pass assembler is needed.
What is the output of the parser from a compiler?
The output of an assembler is a part or all of a product. An assembler can work in a variety of manufacturing operations with the right training.
Does machine operation generate odject code during assembly?
You cannot generate machine code from assembly language without running a program (an assembler). Therefore the machine that generates the machine code must be operational and must be running an assembler program that is appropriate to the target platform. The machine code output from the assembler can then be loaded onto the target platform and executed.

What is the Difference between cross assembler and resident assembler?
An assembler which runs on a computer for which it produces object codes
What is an absolute assembler?
An absolute assembler is a computing term for an assembler which generates code which uses only absolute addresses.
Use of two pass assembler?
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.
What are examples of assembler?
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.
What is meta assembler?
Meta-assembler is a program that accepts the syntactic and semantic description of an assembly language, and generates an assembler for that language.
What is a meta assembler?
Meta-assembler is a program that accepts the syntactic and semantic description of an assembly language, and generates an assembler for that language.
Which program translate assembly language into machine language?
Assembly langue is translated into machine language by an assembler.
How does cross assembler work?
i don't know what is the work of cross assembler?
What are assembler directive listout and explain its types?
list out assembler directive?
