• A. 4GL does not support a high-level of screen interaction
• B. Many database management system packages support 4GLs
• C. A 4GL is a software tool which is written, possibly, in some third generation language
• D. All of the above

Explanation: A 4GL usually provides high-level screen and database interaction, so saying that it does not support high-level screen interaction is…

• A. a program that places programs into memory and prepares them for execution
• B. a program that automate the translation of assembly language into machine language
• C. is a program that appears to execute a source program as if it were machine language
• D. a program that accepts a program written in a high level language and produces an object program

Explanation: An assembler translates assembly-language mnemonics and symbols into machine-language or object code.

• A. save the macro definitions
• B. recognize macro definitions and macro calls
• C. expand macro calls and substitute arguments
• D. All of the above

Explanation: A macro processor stores definitions, recognizes definitions and calls, and expands each call by substituting its arguments.

• A. Introduction of data to program is easier
• B. Addresses any symbolic, not absolute
• C. It is mnemonic and easy to read
• D. All of the above

Explanation: Assembly language replaces binary instructions with readable mnemonics and permits symbolic addresses and easier data representation.

• A. is a term that refers to the control programs of an operating system
• B. allows multiple programs to reside in separate areas of core at the same time
• C. allows the programmer to write base registers and displacements explicitly in the source program
• D. is used to remember which of the general-purpose registers are currently available as base registers, and what base addresses they contain

Explanation: System/370 assembly language permits explicit specification of base registers and displacements in source instructions.

• A. ASRA
• B. ADDA h#01FE, i
• C. LOADA h#OD4E, i
• D. STOREA h#014B, d

Explanation: In the referenced instruction format, hexadecimal machine code 48 decodes to ASRA, an accumulator arithmetic-shift-right instruction.

• A. Reductions
• B. Literal table
• C. Identifier table
• D. Terminal table

Explanation: A literal table records constants written directly in the source program, such as numeric or character literals, so the translator can…

• A. 40
• B. 0111EF
• C. 9001000000
• D. DA000F

Explanation: ASLA is a unary instruction whose opcode in this instruction set is hexadecimal 40, so no operand bytes are appended.

• A. serially reusable
• B. recursive module
• C. reenterable module
• D. non-reusable module

Explanation: A reentrant module can have multiple active execution instances safely, with each instance maintaining its own execution state.

• A. bootstrap loader
• B. loader
• C. linker
• D. None of the above

Explanation: A bootstrap loader is the small absolute loader run automatically at startup or after a restart, often from firmware or a fixed boot…

• A. Program
• B. Algorithm
• C. Decision Table
• D. All of the above

Explanation: A program is an ordered sequence of instructions written in a programming language to make a computer perform a task.

• A. Reductions
• B. Literal table
• C. Identifier table
• D. Terminal table

Explanation: A terminal table records the terminal symbols recognized by a language processor, with an entry for each one.

• A. F8
• B. 03 16
• C. 0111EF
• D. 42 65 61 72

Explanation: The .BYTE pseudo-operation reserves or emits one byte containing the specified hexadecimal value, so h#F8 becomes F8 in machine…

• A. to assign storage to literals, and to ensure that the storage is allocated and appropriate locations are initialized
• B. to assign storage to all temporary locations that are necessary for intermediate results
• C. to assign storage to all variables referenced in the source program
• D. All of the above

Explanation: Storage assignment covers literals, temporary intermediate-result locations, and variables referenced by the source program.

• A. Interpreter is a kind of translator
• B. Interpreter generates an object program from the source program
• C. Interpreter analyses each source statement every time it is to be executed
• D. All of the above

Explanation: An interpreter translates and executes source statements as needed, usually analysing them each time they are executed.

• A. consists of a program and relevant information for its relocation
• B. can itself perform the relocation of its address-sensitive portions
• C. cannot be made to execute in any area of storage other than the one designated for it at the time of its coding or translation
• D. All of the above

Explanation: A non-relocatable program contains address-dependent code that must execute in the particular memory area assigned during coding or…

• A. many functions do not have to be implemented twice
• B. more flexibility is available to the programmer in which he/she may use all the features of the assembler in conjunction with macros
• C. Functions are combined and it is not necessary to create intermediate files as output from the macro processor and input to the assembler
• D. All of the above

Explanation: Integrating macro processing into pass 1 can avoid duplicated functionality, let macros use assembler features, and remove the need for…

• A. Input text and numbers and send commands to the computer
• B. To create new keys to use with your computer
• C. To open the computer up
• D. To create pictures and images and send them to your computer

Explanation: A keyboard is an input device that lets the user type text, enter numbers, and issue commands through keys.

• A. Computer literacy
• B. Power supply
• C. Applications software
• D. Connectivity

Explanation: Connectivity means the ability of separate computer systems to communicate and exchange data, commonly through a network.

• A. EROM
• B. ROM
• C. RAM
• D. PROM

Explanation: ROM is commonly called built-in or permanent memory because it stores essential instructions that remain available when the computer…
