level questions: Types Of Programming Translator

QuestionAnswer
Which type of translator(s), which translates high-level languages into machine code, best protects source code?Compilers
What must first be done for a computer to be able to use intermediate languages?Download the platform specific translator
Whats the differences between an interpreter and a complier?A comiler produces object code/ excutable file An interpreture does not produce an object code An interpreture analyses a program line by line whereas a compiler does the whole block of code A compiler will not procuce an executable file if an error is found but an interpreture will run the code until the first error is detetced Interpreted code will excute slower than excuting the object code produced by a complier Do not need a compiler to excute a compiled program but when running interpreted code the interpreture always needs to be present Once compiled source code is no longer needed to run the program but an interpreture always needs source code at runtime Compiled code can only excute on a machine with the same processor type whereas interpreted code is more portable
- Give the differences between source code and object codeSource code is written in high-level or assembly language whereas object code is written in machine language + all differences between high and low level languages, such as: - Source code is easy to understand - Source code is easy to modify - Source code contains fewer statements than object code
What type of translator can be used to translate assembly language into machine code?Assemblers
Which two types of translator can be used to translate high-level languages into machine code?Compilers Interpreters
Which type of translator translates high-level languages into machine code line-by-line?Interpreters
Why does the computer use translators?In order for a program to be executed by a computer’s processor, it must be in the form of a machine code program
What are the 3 types of translator called?Interpreter Assembler Compiler
Which type of translator translates high-level languages into machine code in one go?Compilers
Which type of translator requires the source code to be present when the program is executed?Interpreters
Which type of translator has procedures to translate each kind of program instruction?Interpreters
What is source code?Code written using a human-readable programming language
What is object code?Code written in machine langauage through translators
What is an intermediate language?'Half way' standard language which can they be translated into computer specific machine code
What is the benefit of using compilers with intermediate languages?They allow the program to be run on all platforms
How do compilers with intermediate languages work?1. Translate the program into the intermediate language 2. Platform specific translator translates this intermediate language code
What is a complilerA program that translates high level languages into machine code in one go
What is an interpreterA program that translates high level languages into machine code line by line
What is an assemblerA program that comverts from low level programming code to machine code
Explain how a compiler better protects source code to an interpreture?A copied file of the code is used to to run the program not the actual source code
