What is computational thinking?, Computational thinking is a thought process involved in formulating a problem and expressing its solution in such a way that computers can effectively carry it out., Why is developing software a complex process?, Because software development involves innovative thinking processes and complex testing procedures., What are the components of computational thinking?, Abstraction, Decomposition & Algorithm design, What are the steps involved in problem solving?, Understand the problem. Construct a plan to solve the problem. Apply the plan. Check for errors and look for improvements in the current plan., What steps are involved in understanding a problem?, We need all data to understand the problem. Then, we must check whether the problem is solvable. If it is solvable, a complex problem can be broken down into simpler modules., What are the characteristics of a proper solution?, Error-free, efficient and reusable., What is abstraction?, A component of computational thinking where certain non-essential characteristics of objects or systems are removed so that it is reduced to a simple set of characteristics., List some examples of abstraction., Variables and functions in programming. Layering in computer networks., What is decomposition?, A component of computational thinking where a large problem is broken down into smaller chunks that can then be solved using computing., What is pattern recognition?, A concept where similar problems are solved by reusing solutions., What are the advantages of using pattern recognition?, Saves effort and time., What is an algorithm?, A problem is broken into a series of logical steps called an algorithm., In what forms, is an algorithm represented?, Flowchart and pseudocode, What is a flowchart?, A method of representing algorithms in pictorial form, depicting the steps and order to be followed to perform a task., What is pseudocode?, A method of representing an algorithm using simple words and mathematical operators., What is the function of a MOD operator?, A MOD operator is used to find remainder of a division operation.
