Worked practice questions

A finite sequence of steps required to get the desired output is called an:

  1. Algorithm
  2. Allotment
  3. Alignment
  4. Allowance
Show answer and solution

Correct answer: A. Algorithm

1. A task is completed by following steps in order. 2. When those steps are finite and produce the wanted output, they get a name. 3. Such a finite sequence of steps is called an algorithm. 4. So the answer is an algorithm. _Source: syllabus Computer Science, Ch 4 'Introduction to Problem Solving'_

An algorithm has a definite beginning, a definite end and consists of:

  1. Fixed prices
  2. Finite steps
  3. Fine steps
  4. Filed steps
Show answer and solution

Correct answer: B. Finite steps

1. An algorithm cannot run forever and still be an algorithm. 2. Its length is bounded as well as its ends. 3. An algorithm has a definite beginning and end and consists of a finite number of steps. 4. So the answer is finite steps. _Source: syllabus Computer Science, Ch 4 'Introduction to Problem Solving'_

The two common methods of representing an algorithm are pseudocode and:

  1. Floorplan
  2. Flowmeter
  3. Flowchart
  4. Flashcard
Show answer and solution

Correct answer: C. Flowchart

1. An algorithm has to be written down before it is coded. 2. Two standard ways of writing it are named. 3. There are two common methods of representing an algorithm, flowchart and pseudocode. 4. So the other one is a flowchart. _Source: syllabus Computer Science, Ch 4 'Introduction to Problem Solving'_
