  1. Machine

  2. Application Language

  3. Low-level Language

  4. High-level Language
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Functional languages, such as Lisp or Haskell, are often referred to as application languages because they are designed to solve problems by evaluating functions rather than executing a sequence of imperative commands.

Multiple choice

Machine language and assembly language are examples of

  1. low level languages

  2. high level languages

  3. both (1) and (2)

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

Machine language and assembly language are considered low-level languages because they are very close to the hardware architecture and require little to no abstraction.

  1. x is a 4-digit integer

  2. x cannot be greater than a 4 digit integer

  3. x is a 4-bit integer

  4. none of above
Reveal answer Fill a bubble to check yourself
C Correct answer
