2.1.3 Thinking Procedurally, 2.1.4 Thinking Logically

Question 1

Thinking procedurally

Answer 1

Identifying the individual parts of a bigger problem. Then breaking down the problem into smaller sub problems

Question 2

purpose of problem decomposition

Answer 2

to make complex problems easier to solve and more manageable by allowing tasks to be divided between a group of people according to individual skills.

Question 3

Top-down modular design (structure diagram)

Answer 3

Breaking down a problem into smaller sub-tasks.

Question 4

benefits of top down design

Answer 4

-problems can be solved and modules developed by different people.
-tasks can be tested separately.
-modules are self contained

Question 5

Top-down design (also know as stepwise refinement) is a method used to help identify the components of a problem. List the advantages of using this method

Answer 5

It’s an advantage as it saves time as different programmers can work on different sub problems the program will also become easier to manage. It is more efficient as it is breaking down a problem into smaller sub programs so you can solve.​

Parts of the solution may be reusable elsewhere​

Question 6

two advantages of using reusable components

Answer 6

more reliable than newly coded components as they have already been tested.
This saves time money and resources.

Question 7

State another name given to top-down design

Answer 7

Stepwise refinement

Question 8

What sort of problem is top-down design suited to

Answer 8

Large, complex problems

Question 9

What is the second stage of thinking procedurally in software development

Answer 9

Identifying components of a solution

Question 10

How can the lowest level subproblems in top-down design in code

Answer 10

As self contained modules or subroutines

Question 11

What do software developers need to consider when recombining components of a solution

Answer 11

The order in which subroutines are executed and how they interact with each other, based on their role in solving the problem

Question 12

What must a software developed do before designing a subroutine to solve a particular problem

Answer 12

See whether it is possible for an already existing subroutine or module to be used

Question 13

What must a software developer do before designing a subroutine to solve a particular problem

Answer 13

See whether it is possible of an already existing subroutine or module to be used

Question 14

What is a decision

Answer 14

A result reached after consideration

Question 15

When are decisions made

Answer 15

A decision is made whenever u have a choice to make

Question 16

What is the shape given to a decision icon in a flow chart

Answer 16

A diamond

Question 17

How do u make effective decisions

Answer 17

By evaluating the importance of different factors and selecting options which satisfy the needs of the task the most appropriately

Question 18

Does the result of a decision affect the flow of a program

Answer 18

The program will follow a diffrent route depending on the decision made by the user
