All Free Software Engineering MCQs with Answers

• A. Machine language
• B. Assembly language
• C. High level language
• D. All of the above

Explanation: LDA B is written using an assembler mnemonic and symbolic operand, so it is assembly language.

• A. lexical analysis
• B. syntax analysis
• C. general syntax analysis
• D. interpretation analysis

Explanation: Lexical analysis groups the character stream into tokens or syntactic classes such as identifiers, keywords, and operators.

• 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 self-relocating program contains code that adjusts its own address-sensitive instructions when loaded at a different location.

• A. compiler
• B. macroprocessor
• C. two pass assembler
• D. load-and-go assembler

Explanation: A load-and-go assembler translates source directly into absolute machine code and loads it into memory for immediate execution, without…

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

Explanation: In the given assembly notation, CHARI uses opcode DA and the hexadecimal operand 000F, producing the machine instruction DA000F.

• A. A greater degree of machine independence
• B. Improved debugging capability, and superior documentation
• C. Fewer people, less management and shorter transition in learning time
• D. All of the above

Explanation: High-level languages reduce dependence on a particular machine, make debugging and documentation easier, and generally reduce development…

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

Explanation: The leading 08 identifies LOADA, and the remaining 0D4E is the hexadecimal operand with immediate addressing.

• A. Utility program
• B. Security software
• C. Networking software
• D. Documentation system

Explanation: Merging records from files is a general file-processing function provided by a utility program.

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

Explanation: The hexadecimal ASCII codes for the characters B, e, a, and r are 42, 65, 61, and 72 respectively.

• A. mouse
• B. printer
• C. keyboard
• D. scanner

Explanation: A mouse, keyboard, and scanner send data into the computer, so they are input devices.

• A. EBCDIC
• B. Binary numbering system
• C. Unicode
• D. ASCII

Explanation: ASCII is the traditional character code commonly represented using 8 bits in its extended form, with a distinct numeric code for each…

• A. ensure that the system processes data as it was designed to and that the results are reliable
• B. protect data from accidental or intentional loss
• C. inspect the system and check that it is built as per specifications
• D. ensure privacy of data processed by it

Explanation: A system control is designed to keep processing consistent with the approved design and to make its outputs dependable.

• A. A CD-RW can be written to, but a CD-ROM can only be read from.
• B. They are the same - just two different terms used by different manufacturers.
• C. A CD-ROM holds more information than a CD-RW.
• D. A CD-ROM can be written to and a CD-RW cannot.

Explanation: CD-ROM media are read-only, whereas CD-RW media can be erased and written again.

• A. microchip
• B. macrochip
• C. macroprocessor
• D. calculator

Explanation: A microprocessor is implemented as an integrated circuit, commonly called a microchip, and performs the computer's processing functions.

• A. Monitor and Printer
• B. Floppy disc nad CD
• C. Keyboard and Mouse
• D. Windows 2000 and Windows NT

Explanation: Monitors and printers are standard examples of output devices: a monitor displays results and a printer produces them on paper.

• A. Input
• B. Output
• C. Software
• D. Storage

Explanation: A printer receives data from the computer and presents it as printed text or images, so it is an output device.

• A. computer network
• B. distributed system
• C. both A and B
• D. none of these

Explanation: A distributed system consists of separate computers that cooperate while appearing to users as one coherent system.

• A. Keyboard
• B. Monitor
• C. Hard disk
• D. Icon

Explanation: A keyboard uses physical or virtual keys to enter text, commands, and other information into a computer.

• A. Latch
• B. Accumulator
• C. Buffer
• D. Accumulator

Explanation: A latch is a bistable electronic circuit that can hold one bit, either 0 or 1.

• A. Bus lines
• B. Wire Lines
• C. Logic Paths
• D. Gate ways

Explanation: Bus lines are shared communication pathways that carry data, addresses, and control signals between components on the system board.
