There are two types of languages used within computer systems:
High Level
Low Level
Mid Level
Level 42
A high level programming language is...

BENEFITS OF USING DECISION TREES include:
Uses quantitative data only – ignores qualitative aspects of decisions
It is based on assumptions and estimates
Choices are set out in a logical way
Assignment of probabilities and expected values prone to bias
DRAWBACKS OF USING DECISION TREES include:
Probabilities are just estimates – always prone to error
Choices are set out in a logical way
Potential options & choices are considered at the same time
Use of probabilities enables the “risk” of the options to be addressed

Programming Methods- the use for programming (a) it depends upon the size and the complexity of the program. When a program beyond a particular size and complexity, a traditional methodology may fail to give efficient results and in the case one has to either use a new method which will satisfy the need.
The programmers may use them in other parts of the programs knowing that only their abstract properties without concern for the details of their implementation
