Problem solving strategies

Question 1

data mining

Answer 1

• used to identify patterns or outliers in large sets of data, termed big data
• used in software to spot trends or identify correlations between data which are not immediately obvious
• can be used to make predictions

Question 2

data mining drawbacks

Answer 2

• often involves the handling of personal data

Question 3

performance modelling

Answer 3

• the behaviour of a system/program is tested or simulated before it is implemented
• it is cheaper and less time-consuming than testing the real system

Question 4

concurrent processing

Answer 4

• multiple processes appearing to happen simultaneously
• giving processes a slice of the processing time
• having multiple processors each carrying out a different process
• process happening at the same time
• one process may start before previous one has finished
