1-Dont try to cram or spend more time here just read it fast and cover syllabus then practice MCQ's cheptor of same topic to check your progress. . |
2-Wrong options are also given but dont concentrate there, Right answer is in bold format. |
Q41 ⇒ A base register table is used to remember which of the general-purpose registers are currently available as base registers, and what base addresses they contain [other wrong options] [Discuss in forum] is a term that refers to the control programs of an operating system allows multiple programs to reside in separate areas of core at the same time allows the programmer to write base registers and displacements explicitly in the source program |
Q42 ⇒ Convert the ASCII/BEAR/assembly language pseudo-ops into hexadecimal machine language 42 65 61 72 [other wrong options] [Discuss in forum] F8 03 16 0111EF |
Q43 ⇒ The Process Manager has to keep track of: both (a) and (b) [other wrong options] [Discuss in forum] the status of each program the priority of each program the information management support to a programmer using the system |
Q44 ⇒ Which of the following systems software does the job of merging the records from two flies into one? Utility program [other wrong options] [Discuss in forum] Security software Networking software Documentation system |
Q45 ⇒ Assembly code data base is associated with assembly language version of the program which is created by the code generation phase and is input to the assembly phase [other wrong options] [Discuss in forum] a permanent table which lists all key words and special symbols of the language in symbolic form a permanent table of decision rules in the form of patterns for matching with the uniform symbol table to discover syntactic structure consists of a full or partial list or the tokens as they appear in the program. Created by Lexical analysis and used for syntax analysis and interpretation |
Q46 ⇒ In analyzing the compilation of PL/I program, the term "Machine independent optimization" is associated with creation of more optional matrix [other wrong options] [Discuss in forum] recognition of basic syntactic constructs through reductions recognition of basic elements and creation of uniform symbols use of macro processor to produce more optimal assembly code |
