Free Software Development Lifecycle MCQs with Answers

• A. 16
• B. 4
• C. 2
• D. 1

Explanation: Under the traditional MBR partitioning scheme, a disk can contain only one extended partition, which serves as a container for logical…

• A. GNU's not Unix
• B. Greek Needed Unix
• C. General Unix
• D. General Noble Unix

Explanation: GNU is a recursive acronym meaning “GNU's Not Unix.” It refers to the Unix-compatible free-software project, not to “General Unix” or the…

• A. wc - r
• B. wc - w
• C. wc - c
• D. wc - 1

Explanation: The `wc -c` option counts the number of bytes in a file and is traditionally described in basic Unix questions as counting characters.

• A. 83
• B. 82
• C. 5
• D. 4

Explanation: Partition type 82 is the Linux swap partition ID used by `fdisk`. Type 83 denotes a normal Linux filesystem, while type 5 denotes an…

• A. rpm -q
• B. rpm -a
• C. rpm -d
• D. rpm -1

Explanation: The RPM query option is `-q`, used to query whether a package is installed and retrieve package information.

• A. ypwhich
• B. ypbind
• C. ypcat
• D. yppoll

Explanation: `ypbind` binds an NIS client to an NIS server and maintains the domain-to-server information needed for NIS requests.

• A. *
• B. ?
• C. [!ijk]
• D. [ijk]

Explanation: The `*` shell wildcard matches any sequence of characters, including an empty sequence.

• A. SPARC
• B. IBM-compatible
• C. Alpha
• D. Macintosh

Explanation: The listed Red Hat architecture choices traditionally included IBM-compatible x86, Alpha, and SPARC systems, whereas Macintosh was not…

• A. ^pat
• B. $pat
• C. pat$
• D. pat^

Explanation: In a grep regular expression, `$` anchors a pattern to the end of a line, so `pat$` matches lines ending with `pat`.

• 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 relocatable program includes the program code together with information that allows address-sensitive parts to be adjusted when it is…

• A. Top-down development
• B. Bottom-up development
• C. Left-Right development
• D. All of the above

Explanation: Top-down development starts with the system's main control modules and progressively refines or replaces lower-level details.

• A. Syntax analysis
• B. Code generation
• C. Storage assignment
• D. Assembly and output

Explanation: Assembly and output resolves symbolic labels into actual addresses and produces machine-language output.

• 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.
