Multiple choice

'Natural Language 'refers to

  1. programming language

  2. machine language

  3. spoken language

  4. assembly language
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Natural language refers to languages that humans use for communication, such as English, Hindi, or Spanish. This contrasts with artificial or formal languages like programming languages (Python, Java) or machine language (binary), which are designed for specific computational purposes.

Multiple choice

FORTRAN stands for

  1. training

  2. formula translation

  3. translation

  4. train

B Correct answer
Explanation

FORTRAN is a programming language whose name comes from 'FORmula TRANslation'. It was developed in the 1950s specifically for scientific and numerical computations. The name accurately describes its purpose - translating mathematical formulas into executable code.

Multiple choice

Which is a high level language of computer?

  1. Machine language

  2. English language

  3. Assembly language

  4. FORTRAN
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

High-level languages are programming languages that are more abstract and easier for humans to read and write compared to low-level languages. FORTRAN (developed in 1957) was one of the first high-level programming languages. Machine language and Assembly language are both low-level languages that work closer to the hardware. English is a natural language, not a programming language.

Multiple choice

Structure in C++ can store

  1. only similar data type

  2. any data type

  3. only two data types

  4. only 5 data types
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Structures in C++ can contain members of different data types (int, float, char, etc.) unlike arrays which require similar types. This makes structs versatile for grouping related data.

Multiple choice

C++ language is a/an

  1. object oriented language

  2. structured language

  3. procedural language

  4. none of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

C++ is primarily an object-oriented language that supports key OOP features like classes, inheritance, and polymorphism, though it also supports procedural and structured programming paradigms.

Multiple choice

SQL is the

  1. first generation language

  2. second generation language

  3. third generation language

  4. fourth generation language
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

SQL (Structured Query Language) is a fourth-generation language (4GL) because it provides a high-level abstraction for working with databases. Unlike 3GLs like C or Java that require detailed procedural instructions, SQL allows users to specify what data they want using declarative statements like SELECT, letting the database engine handle the implementation details.

Multiple choice

A programming language used by desktop publishing program to describe the way a page should look is known as

  1. prescript

  2. postscript

  3. script

  4. software
Reveal answer Fill a bubble to check yourself
B Correct answer

  1. Corel Draw

  2. Pascal

  3. MS Word

  4. Sybase
Reveal answer Fill a bubble to check yourself
