2.1 Algorithms

Question 1

Abstraction

Answer 1

Representing ‘real world’ problems in a computer using variables and symbols and removing unnecessary elements from the problem

Question 2

Decomposition

Answer 2

Breaking down of a large problem into smaller problems

Smaller problems are easier to solve

They can be created independently of the other problems

They can be tested independently

Then combined to produce the full problem

There is not always one right answer. A problem could decomposed in several valid ways
