Unit 4 – Programming
Introduction
This assignment will examine and develop computational skills and principles of computer programs.
I will apply these computational skills for the development, testing, refinement, and review of
computer programs for various purposes. Furthermore, I will analyze problems and processes in
order to identify solutions that can be turned into software applications.
Identifying the Computation Skills Required
Decomposition
Decomposition is one of the first computational skills as the main process would be to describe
problems and processes as a set of structured steps and this would usually interpret problems to
denote a step by step sequence in an instructed way for better understanding. It is the process of
breaking complex ideas down into smaller, more manageable parts. Sometimes this process may be
called factoring. The process of breaking a larger problem down into a number of smaller problems
often improves the chances of success.
Identifying and describing problems and processes
In this process, I will be able to list down every problem and process in a concise way with using
convenient language to match the problem source. For example, if I deal with a problem that relates
to financial information, I could use the terms from the financial sector accurately and this would
imply that there will be familiarity of using the technical language used in the business sector that is
relevant to the main problem.
