UNIT 4 – PROGRAMMING ASSIGNMENT A
Introduction: In this presentation I going to talk about computational thinking
skills and principles of computer programming. How computational thinking
work, how we used it in our daily bases etc. Also, principles of computer
programming how computers work. And we going to look at many things like
logic, data set, loop and how both program work.
Computational Thinking: Computational thinking is to solve any problem
using computer. Computers solve these problems in different ways by
understanding the scenario of the problem, before it tries to solve it, the
problem need to be identified to understand. This problem can be display in a
way so the computer and a human can understand. It is also important that
computer and the human should know what is going on in order understand
the problem.
Computational thinking let us to take a complex problem and understand what
the problem is so we can create a solution for that problem if it is possible.
When we talk about computational thinking, we need to understand how
computational thinking works. computational thinking processes a problem by
four things: Abstraction, Decomposition, Pattern recognition and Pattern
generalisation.
Decomposition: Decomposition is breaking down complex problem into
smaller pieces. If a problem does not get decompose is going to be much hard
,to solve the complex problem. During the problem there are multiple stages
which can be take lots of time so it more difficult than breaking down the
problem into a number of problem and solving them one by one. Breaking
down a problem into smaller pieces is make more easier which mean the
problem can be solved in much more detail.
An example of decomposition would be a person cleaning a garden. To
decompose this problem, he would need to consider the following factors:
1. What do you need to remove from the garden?
2. Which tools to use?
3. How far the garden is?
4. What soap or disinfectant the person decides to use?
Identify the skills are used to find solutions to problems.
• Use on Work: A junior worker is getting ready to talk about computer
programming at a local store, So the worker needs to consider few
things. First, the worker must look at some computer programs that his
boss gave him. Then he should research on it, so if the worker finds any
problems, he must fix them. And this is where problem-solving comes in.
Once he understands the programs, then he can pick out the main ideas
that make it easier for him to solve it. It is like finding the most important
stuff on the program. He also needs to explain all in a way that everyone
can understand during the talk. Being good at using computers and
understanding different programming things also is important. And if
things change or if he gets new things add into it, he has to be okay with
that and he have to his adjust plans. Also, he must manage his time well
to get everything done.
, Pattern Recognition: The process of identifying patterns and similarities within
an issue is known as pattern recognition. Upon breaking down a complex
problem, we frequently see patterns recognition the smaller difficulties and
issues we produce. The patterns are traits or features that some of the issues
could have in common. So, finding a pattern in a problem is very important
because it make the task easier to complete. So, if the problem gets simpler to
solve by finding a pattern, then we can use the same pattern solution to solve
any kind of problem.
Identify the skills are used to find solutions to problems.
• So, after he understands the problem and find it out the problems and
break things down into smaller pieces, he needs to watch out the similar
patters into these small problem because breaking down a complex
problem, he will frequently see patterns recognition the smaller
difficulties and issues the problem produce. So, finding these problems is
very important because it will make his work easier.
Abstraction: Simple term of abstraction is removing unnecessary details. We
can do this by only focusing on an important information and ignoring
irrelevant detail. So, once we find out that do, we need to ignore then we can
use abstraction to collect general features and the details to find out what is
the problem is. This allows us to create a basic idea of the issue and how we
can solve it.
Identify the skills are used to find solutions to problems.
• After he find the Pattern Recognition into those problem. He needs to
remove them because these problems are unnecessary so once he do
that, then he can work out the solution for the computer program.
