- 3. A Language Processor is a software program designed or used to perform tasks such as processing program code to machine code. Language processors are found in languages such as C++, Java, etc.
- 6. ADVANTAGES AND DISADVANTAGES OF LANGUAGE PROCESSORS ADVANTAGES: Modification of user program can be easily made and implemented as execution proceeds. Type of object that denotes a various may change dynamically.
- 7. DISADVANTAGES: The execution of the program is slower. Memory consumption is more.
- 8. AN ASSEMBLER IS A PROGRAM THAT CONVERTS ASSEMBLY LANGUAGE INTO MACHINE CODE. IT TAKES THE BASIC COMMANDS & OPERATIONS FROM ASSEMBLY CODE AND CONVERTS THEM INTO BINARY CODE THAT CAN BE RECOGNISED BY A SPECIFIC TYPE OF PROCESSOR. Assembler Assembly language program Input Output Machine language program
- 9. ADVANTAGES OF USING ASSEMBLER Very fast in translating assembly language to machine code. It is often very efficient because it is a low level language.
- 10. DISADVANTAGES OF USING ASSEMBLER Takes a lot of effort to write and maintain the code. It limits algorithm designs.
- 11. AN INTERPRETER IS A COMPUTER PROGRAM, WHICH CONVERTS EACH HIGH-LEVEL PROGRAM STATEMENT INTO THE MACHINE CODE. THIS INCLUDES SOURCE CODE,PRE-COMPILED CODE & SCRIPTS. Interpreter High level language program Input Output Result of program execution
- 12. ADVANTAGES OF USING INTERPRETER Instructions are executed as soon as they are translated. Errors can be quickly spotted- once an error is found, the program stops running & the user is notified at which part of the program the interpretation has failed.
- 13. DISADVANTAGES OF USING INTERPRETER Interpreted programs runs slowly as the processors has to wait for each instruction to be translated before it can be executed. Interpreters do not optimise code- the translated code is executed as it is.
- 14. COMPILER COMPILER IS A TRANSLATOR PROGRAM THAT IS USED TO CONVERT A HIGH LEVEL LANGUAGE PROGRAM INTO MACHINE LANGUAGE. IT TRANSLATES THE WHOLE PROGRAM AT ONES AND GENERATES THE OBJECT CODE ALONG WITH A LIST OF ERRORS
- 15. ADVANTAGES OF USING COMPILER Compiled programs run quickly, since they have already been translated. Compilers optimise code. Optimised code can run quicker and take up less memory space. A compiled program can be supplied as an executable file.
- 16. DISADVANTAGES OF USING A COMPILER The source code must be re-compiled every time the programmer changes the program. Source code compiled on one platform will not run on another-the machine code is specific to the processor’s architecture.
