PART – A (10 X 2 =20 marks)

1. Define upward compatibility in systems.
2. Distinguish between direct addressing and indirect addressing.
3. Consider the following sequence
X WQU Y
Y EQU Z
Z RESW 1
Is a two pass assembler can resolve such a sequence of definition? Justify your answer.
4. What is the data structure used to organize the symbol table and operation code table in a simple assembler Why it is preferred?
5. What are the advantages of dynamic linking?
6. What is the function of pass 2 of a loader?
7. What is the use of DEFTAB (Definition table) NAMTAB (Name table) and ARGTAB (Argument table) in macro processor?
8. What is the purpose of conditional compilation statement in ANSI C preprocessor?
9. What are the tasks performed by document editing process?
10. How the mapping of view buffer to a window is done?
