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. |
Q1 ⇒ An interpreter is A program that appears to execute a source program as if it were machine language [other wrong options] [Discuss in forum] A program that places programs into memory an prepares them for execution A program that automate the translation of assembly language into machine language A program that accepts a program written in high level language and produces an object program |
Q2 ⇒ A computer programe that converts the whole programe into machine language at a single time is called Compiler [other wrong options] [Discuss in forum] Translater Interpreter All of the above |
Q3 ⇒ Which of the following electronic component are not found in ordinary ICs? Inductors [other wrong options] [Discuss in forum] Diodes Resistors Transistors |
Q4 ⇒ Which of the following is a phase of a compilation process ? Both (a) and (b) [other wrong options] [Discuss in forum] Lexical analysis Code generation None of these |
Q5 ⇒ Uniform symbol table consists of full or partial list of the token's as they appear in the program created by Lexical analysis and used for syntax analysis and interpretation. [other wrong options] [Discuss in forum] contains all constants in the program a permanent table which lists all key words and special symbols of the language in symbolic form. is a permanent table of decision rules in the form of patterns for matching with the uniform symbol table to discover syntactic structure. |
Q6 ⇒ Forward reference table(FRT) is arranged like - Linked list [other wrong options] [Discuss in forum] Stack Queue Double linked list |
Q7 ⇒ In which way a macro processor for assembly language can be implemented? All of these [other wrong options] [Discuss in forum] Processor incorporated into pass 1 of a standard two pass assembler Independent one-pass processor Independent two-pass processor |
Q8 ⇒ Macro processor is an inbuilt function of - Assembler [other wrong options] [Discuss in forum] Loader Linker Editor |
Q9 ⇒ Intel introduced first 32 bit processor in 1985 [other wrong options] [Discuss in forum] 1987 1989 1993 |
Q10 ⇒ In which of the following no information hiding is done ? 1001000010101 [other wrong options] [Discuss in forum] load R1 , A run test, prog compile prog 1, prog 2 |
Q11 ⇒ The translator used by second generation languages is? assembler [other wrong options] [Discuss in forum] interpreter compiler linker |
Q12 ⇒ The number of clock cycles necessary to complete 1 fetch cycle in 8085 is 4 or 6 [other wrong options] [Discuss in forum] 3 or 4 4 or 5 6 or 7 |
Q13 ⇒ Scissoring enables a part of data to be displayed [other wrong options] [Discuss in forum] no data to be displayed entire data to be displayed full data display on full area of screen |
Q14 ⇒ A memory bus is used for communication between Processor and Memory [other wrong options] [Discuss in forum] ALU and Register Input and Output devices All of the above |
Q15 ⇒ Advantage of incorporating the macro-processor into pass 1 is that all of these [other wrong options] [Discuss in forum] many functions more flexibility is available to the programmer in that he may use all the features of the assembler in conjunction with macros. functions are combined and it is not necessary to create intermediate files as output from the macro-processor and input to the assembler. |
Q16 ⇒ Which of the following macros can put a macro assembler into an infinite loop ? MACRO M2, XIF EQ, XM2 XENDCIF NE, XWORD X + 1ENDCENDM [other wrong options] [Discuss in forum] MACRO M1, XIF EQ, X if X = 0 then....M1 X + 1ENDCIF NE, X : IF X ≠0 then......WORD X : address (X) is stored hereENDCENDM both (a) and (b) none of these |
Q17 ⇒ Advantage of using assembly language rather than machine language is that all of these [other wrong options] [Discuss in forum] it is mneomonic and easy to read addresses any symbolic not absolute introduction of data to program is easier |
Q18 ⇒ Which of the following system program forgoes the production of object code to generate absolute machine code and load it into the physical main storage location from which it will be executed immedia Load-and-go-assembler [other wrong options] [Discuss in forum] Linker Macroprocessor Two pass assembler |
Q19 ⇒ In analyzing the compilation of PL/I program, the term "Machine independent optimization" is assosiated with creation of more optical matrix [other wrong options] [Discuss in forum] recognition of basic elements and creation of uniform symbols use of macro-processor to produce more optimal assembly code recognization of basic syntactic construction through reductions |
Q20 ⇒ A system program that set-up an executable program in main memory ready for execution is loader [other wrong options] [Discuss in forum] linker assembler text editor |
Or |
