1.2.2 Applications Generation

What is the role of an Assembler?

• Loads the executable object program into memory

• Links object code files and modules together

• Converts assembly language into machine code

• Converts high level language to machine code

What does Closed Source software imply?

• Software that optimizes computer performance

• Software with freely available source code

• A collection of precompiled programs

• Software sold with restrictions and without source code access

What is the final stage of compilation called?

• Optimisation

• Code Generation

• Lexical Analysis

• Syntax Analysis

What is the main function of Compilers?

• Linking object code files together

• Checking source program for syntax errors

• Converting high level language to machine code

• Translating machine code to high level language

What is the difference between Compilers and Interpreters?

• Interpreters link object code files, while Compilers do not

• Interpreters convert code line by line, while Compilers convert the whole code at once

• Compilers convert code line by line, while Interpreters convert the whole code at once

• Compilers check for syntax errors, while Interpreters do not

What happens during Lexical Analysis?

• Syntax errors are checked using syntax diagrams

• The source code is converted into machine code

• Extra spaces and comments are removed from the source code

• The object code is optimized

What are Libraries in programming?

• A program that loads the executable object program into memory

• Software whose source code is freely available

• A collection of already compiled programs

• A translator that converts high level language to machine code

What is the purpose of Linkers?

• To load the executable object program into memory

• To remove extra spaces and comments from the source code

• To place machine addresses in the compiled program for linking

• To convert assembly language into machine code

What is the main function of Loaders?

• To load the executable object program and its libraries into memory

• To check the source program for syntax errors

• To link object code files and modules together

• To convert high level language to machine code

What defines Open Source software?

• Software sold with a licence and usage restrictions

• Software whose source code is not available to users

• Software whose source code is freely available for modification

• A collection of programs which are already compiled
