1241. What do you call the translator which takes assembly language program as input & produce machine language code as output?

• A. Compiler
• B. Interpreter
• C. Debugger
• D. Assembler

Explanation: An assembler translates assembly-language mnemonics and operands into machine-language instructions. A compiler generally translates a high-level language, while an interpreter executes translated statements incrementally.

1242. Which statement is valid about computer program?

• A. High level languages must be converted into machine language to execute
• B. High level language programs are more efficient and faster to execute
• C. It is more difficult to identify errors in high level language program than in low level programs
• D. All of above

Explanation: A high-level program must be translated into machine code, either before execution by a compiler or during execution by an interpreter. High-level code is generally easier, not harder, to understand and debug, and it is not necessarily faster than low-level code.

1243. A(n)____________language reflects the way people think mathematically.

• A. cross-platform programming
• B. 3GL business programming
• C. event driven programming
• D. functional

Explanation: Functional languages express computation through mathematical-style functions and the evaluation of expressions. The other options describe portability, business programming, or a programming approach based on events.

1244. A(n)_____________program is one that is ready to run and does not need to be altered in any way.

• A. Interpreter
• B. High level
• C. Compiler
• D. Executable

Explanation: An executable program has been translated into a form the operating system and processor can run directly. An interpreter or compiler is a translation tool, while “high level” describes a language rather than a ready-to-run program.

1245. A detailed written description of the programming cycle and the program, along with the test results and a printout of the program is called___________?

• A. documentation
• B. output
• C. reporting
• D. spec sheets

Explanation: Documentation records the programming process, program details, test results, and related printouts so the system can be understood and maintained. Output refers only to the results produced by a program.

1246. A set of rules for telling the computer what operations to perform is called a______________?

• A. procedural language
• B. structures
• C. natural language
• D. programming language

Explanation: A programming language is a formal set of rules and symbols used to specify operations for a computer. A procedural language is only one type of programming language, not the general term.

1247. When a logic bomb is activated by a time-related event, it is known as a____________?

• A. Time-related bomb sequence.
• B. Virus.
• C. Time bomb.
• D. Trojan horse.Computer Online Quiz

Explanation: A logic bomb triggered by a specified date or time is called a time bomb. A logic bomb can also be triggered by another condition, so the time-based trigger is what defines this subtype.

1248. When creating a computer program, the____________designs the structure of the program?

• A. End user
• B. System Analyst
• C. Programmer
• D. All of the above

Explanation: A systems analyst plans requirements and designs the overall structure of a program or system. The programmer implements that design, and the end user normally operates the finished system rather than designing it.

1249. COBOL is an acronym for________________?

• A. Common Business Oriented Language
• B. Computer Business Oriented Language
• C. Common Business Operated Language
• D. Common Business Organized Language

Explanation: COBOL expands to Common Business Oriented Language, reflecting its original use in business data processing and commercial applications.

1250. Which one of the following is NOT a computer language?

• A. MS-Excel
• B. BASIC
• C. COBOL
• D. C++

Explanation: BASIC, COBOL, and C++ are programming languages. MS Excel is spreadsheet application software, not a computer language.
