what do you mean by assembler in computer science
Answers
An Assembler Program creates object code by translating combinations of mnemonics and syntax for operations and addressing modes into their numerical equivalents.
- A Macro assembler includes a macroinstruction facility so that (parameterized) assembly language text can be represented by a name, and that name can be used to insert the expanded text into other code.
- A Cross assembler is an assembler that is run on a computer or operating system of a different type from the system on which the resulting code is to run.
- A High-level assembler is a program that provides language abstractions more often associated with high-level languages, such as advanced control structures (IF/THEN/ELSE, DO CASE, etc.) and high-level abstract data types, including structures/records, unions, classes, and sets.
- A Microassembler is a program that helps prepare a microprogram, called firmware, to control the low level operation of a computer.
- A Meta-assembler is a term used in some circles for "a program that accepts the syntactic and semantic description of an assembly language, and generates an assembler for that language..."
Answer:
Assembler in computer science
Explanation:
Assembler is a program that converts the big instruction into a pattern of bit which can be further used for performing the basic operations. Sometimes it is also known by the instruction assembly language.
Programmer use sequence of character.
1) This sequence of code is known by source code or source program which clearly specifies which program is the starting point.
2) It takes the statement in the input or source program and which generates a bitstream in the form of (0's and 1's)
3) The output is here the object code or object program which is generated by the input code or source code in the sequence of 0's and 1's.
