Computational methods

Question 1

What is backtracking?

Answer 1

if one pathway to a solution fails the search for successful path begins at last successful point

Question 2

What is Data mining?

Answer 2

Data mining examines large data sets looking for patterns and relationships. Databases are designed to store and process data in predefined ways. When they get large enough, unexpected relationships may be uncovered, especially if other databases are examined as part of the same process

Question 3

What does data mining incorporate?

Answer 3

Cluster analysis
pattern matching
anomaly detection
regression anlysis

Question 4

What is perfromacne moddeling?

Answer 4

Performance modelling is another use of models in computational thinking
###Real life objects and systems###

Question 5

What is pipelining?

Answer 5

Pipelining is a common computing technique where the output of one process can be fed into another
Complex jobs can be divided up into separate pipelines so that parallel processing can occur
This technique parallels real-life situations such as assembly-line processing

Question 6

What is visualisation?

Answer 6

Problems and data can often be better understood when translated into a visual model
