Stepwise refinement is sometimes called top-down design, for the obvious reason that you start the process at the top, with the problem as a whole, and work downwards. Top-down design involves looking at the whole task and breaking it down into smaller, more manageable sub-problems which are easier to solve.

What is the last step in top-down design?
The last step in the system design phase involves logic design of the functional blocks in the circuit architecture [1,14]. The result of the system design phase is a complete description of the system and subsystems down to the transistor level.
Which method is called top-down approach?
A top-down approach (also known as stepwise design and stepwise refinement and in some cases used as a synonym of decomposition) is essentially the breaking down of a system to gain insight into its compositional sub-systems in a reverse engineering fashion.
Which type of programming is also known as top down align or step wise refinement?
Program development includes designing, coding , testing & verification of a program in any computer language for writing a good program, the top down approach can be used. It is also known as systematic programming (or) hierarchical program design (or) step-wise refinement.
What is top-down design of problem solving?
Top down analysis is a problem solving mechanism whereby a given problem is successively broken down into smaller and smaller sub-problems or operations until a set of easily solvable (by computer) sub-problems is arrived at.
What does top-down process follow?
1. What does top down process follow? Explanation: Top down layer focuses on higher to lower abstraction.
What is top-down approach example?
Public Health: The top-down approach in public health deals with programs that are run by whole governments of intergovernmental organizations (IGOs) that aid in combating worldwide health-related problems. HIV control and smallpox eradication are two examples of top-down policies in the public health sphere.
What is a top-down approach Mcq?
Solution(By Examveda Team) Top down approach is used for development. A top-down approach (also known as stepwise design and in some cases used as a synonym of decomposition) is essentially the breaking down of a system to gain insight into its compositional sub-systems in a reverse engineering fashion.
Which of the following is true about top-down design process?
Which of the following is true about top-down design process? Explanation: Top-down design is an approach for deriving a modular design in which the overall design.
Where is top-down design approach used?
Advantage:
| S.No. | TOP DOWN APPROACH |
|---|---|
| 2. | Mainly used by structured programming language such as COBOL, Fortran, C, etc. |
| 3. | Each part is programmed separately therefore contain redundancy. |
| 4. | In this the communications is less among modules. |
| 5. | It is used in debugging, module documentation, etc. |
What is stepwise strategy?
Stepwise approaches are initiatives or programmes that enable producers or enterprises to move in a gradual way towards improved social and/or environmental performance. The defining feature of a stepwise approach is the structured, stepped path to performance improvement that it lays out for producers and businesses.
What is top-down planning?
Top-down planning traditionally involves defining organizational goals on a high level and breaking them down into specific objectives which are then addressed in phases. As the name indicates, top-down planning is an approach that aims at moving gradually from the top to the lower levels of a given hierarchy.
What’s the meaning of top-down?
Definition of top-down
1 : controlled, directed, or instituted from the top level a top-down corporate structure. 2 : proceeding by breaking large general aspects (as of a problem) into smaller more detailed constituents : working from the general to the specific top-down programming top-down design.
Which one of the following is a top-down parser Mcq?
3. Which one of the following is a top-down parser? Explanation: Recursive Descent also known as top down parsing also known to be LL(1).
Which is used in top-down parsing Mcq?
Which of the following derivations does a top-down parser use while parsing an input string? Explanation: In top down parser takes input from Left to right constructing leftmost derivation of the sentence.
Which of the following approaches is also known as the bottom-up approach Mcq?
B. C. D. Explanation: colloidal dispersion is an example of bottom up approach in the synthesis of nano particles.
Which one of the following is the use of function in Python?
Which of the following is the use of function in python? Explanation: Functions are reusable pieces of programs. They allow you to give a name to a block of statements, allowing you to run that block using the specified name anywhere in your program and any number of times.
Which of the following items are present in the function header?
Answer: Function header consists of function name & parameter list.
Which of the following is best type of module coupling?
Which of the following is the best type of module coupling? Explanation: The dependency between module A and B is said to be data coupled if their dependency is based on the fact they communicate by only passing of data.
What are the three design strategies?
Three Design Strategies for Additive Manufacturing
- Direct part replacement. This strategy means additively manufacturing a part that is close to its conventional counterpart in fit, form and function.
- Adaptation.
- Design for AM (DFAM).
What are types of design strategies?
Design strategies
- Folding via stretching.
- Folding without stretching (coming soon)
- Freeform modelling.
- Grid structures.
- Sectioning.
- Subtraction.
- Surface panelling.
