  1. Common Language Runtime

  2. Command Line Runtime

  3. Custom Language Runtime

  4. None

Multiple choice perl

PERL is

  1. Procedural

  2. OOPs

  3. Both

  4. None
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Perl is a versatile programming language that supports both procedural programming (scripts with subroutines and control flow) and object-oriented programming (creating objects, classes, and using inheritance). While Perl was originally procedural, Perl 5 introduced full OOP support with packages, bless operator, and method invocation. The 'Both' option correctly captures Perl's dual nature.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

COBOL (Common Business-Oriented Language) remains one of the most widely used programming languages in mainframe systems, particularly in banking, insurance, and enterprise legacy systems.

Multiple choice general knowledge science & technology

In 1969, Ken Thompson and Dennis Ritchie embarked upon a project to develop a single-user version of MULTICS for a PDP minicomputer. They recognized the need for using a high-level language for portability. This need led Ritchie to develop a new language to write system software for the new system, called UNIX, and wrote an excellent compiler for it. Which is the language I'm talking about?

  1. Java

  2. BCPL

  3. C

  4. PL/I
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Dennis Ritchie created the C programming language at Bell Labs specifically to develop the UNIX operating system on the PDP minicomputer. C was designed as a high-level language that could still write efficient system software, making UNIX portable across different hardware platforms.

  1. J.A. Baughman

  2. Dennis Ritchie

  3. A.Evans Jr

  4. Ted Kaehler
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Dennis Ritchie developed the C programming language at Bell Telephone Laboratories (Bell Labs) in the early 1970s. C was created for developing the UNIX operating system and became one of the most influential programming languages in history.

Java is a programming language developed by ----------at Sun Microsystems

  1. David Gelernter

  2. James Gosling

  3. David Kaminsky

  4. Scott Wallace
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Java was created by James Gosling at Sun Microsystems in 1995, originally called 'Oak' and then 'Green' before being named Java. Gosling developed the language as a platform-independent code for consumer devices. David Gelernter is known for work on parallel computing and tuple spaces.
