First situation
Question 1: What is prototyping?
Web prototyping or called rapid is the process by which a web-based model of the end product is constructed for the purpose of outlining how a website or web application will look and behave. In the world of web prototypes the process of developing a prototype might be more important than the end product. The web prototype, whether it’s on a whiteboard, paper and online is a test site that will include some content, all primary navigation and possibly images and key functional elements.

Question 2:Why do wee need to prototype?
wee need to prototype because it is a sketch or first step before develop web design. This can be difficult if the web developer not sketch prototype and may be some function will miss to put inside the web. Although it can be useful to start testing your sketched designs with real users at this point we don’t recommend it. In the 200+ projects we have done using prototyping we have found it’s faster to get a more coherent design together before starting the testing.

Question 3:What are the advantages and disadvantages of using low-fidelity prototype and high fidelity prototype?
Low -Fidelity
Lower Development cost.
Evaluate multiple design concepts.
Useful communication device.
Proof –of-concept
Disadvantages:
Limited error checking.
Poor detailed specification to code to.
Facilitator-driven.
Navigational and flow limitation
High fidelity
Advantage
Complete functionalit
Fully Interactive
Cleary defines navigational scheme
Look and feel of final product.
Disadvantages:
More expensive to develop
Time –consuming to create
Inefficient for proof concept design

Question 4:Explains different type of prototyping?
Basic Prototyping – This is generally a home built effort. It isn’t pretty and it’s often made from things lying around the house, but it will prove the theory and it is the first step in making the distinction between Innovation and Inventing. For most of us this involves breaking the problem down to its basic functions and assembling parts that replicate those many functions into a new form.
I often walk the aisles of a retail store with a mental list of the functions I am trying to replicate and purchase items that have those parts. Then I retreat to my shop where I dismantle the items from the store and re-purpose those parts from my list. Remember, it doesn’t have to be pretty, it has to work.
Advanced Prototyping – Normally a little better looking than a basic prototyping effort, an advanced prototype is generally done with the help of a professional trade. That is, you have taken your basic prototype to a machine shop, or a plastics shop and had parts of it made professionally to assemble back in the garage. You sometimes hear this referred to as a “Looks Like – Works Like” model.
Manufacturing Prototype – This is where it gets a little more complicated. A manufacturing prototype is one that is exactly like the final manufactured product. That is, it’s the exact shape, size and function of the final product. What sets this apart from other prototyping is that it can be used to create the machine tooling actually used in the manufacturing process.
In the old days this was it – you created a manufacturing prototype and you sent it out to a company who then took it apart and made
all the tooling from it. That still happens today, but as technology advances the process has changed a bit and it’s not done that way as often as it used to be.
Virtual Prototyping – Created in a computer, this relatively new form of prototyping represents both good and bad to the inventor. At its most primitive, this form of prototyping is a 3D file that can be used to output data to a tool making machine.
Great for a simple part, but as your invention gets more complicated you will need to work in more complicated programs. These programs will allow you to do things like motion studies, flow dynamics, and in essence digitally create a manufacturing prototype.
Question 5:What are differences between prototyping and wireframe?
Wireframe is a low fidelity representation of a design.
Characteristics of wireframes:
wireframe should cleary show:
1)The main group of content
2)The structure of information
3)A description and basic visualisation of the user interface interaction.
A prototype is middle of high fidelity representation of the high fidelity representation
of the final product,which simulates user interface of interaction.
Characteristics of prototype:
Prototype should allow the user to:
-experience content and interactions with the interface
-test the main interactions in away similar to the final product
Second situation:
The step one that should be start with make wire frame.A wire frame is a low fidelity representation of a design before implementation are made.The wireframe contains some elements to insert the web page and the user need to think about the platform which want to use in programming in html or J2EE.
Design the website are important before we make some website.After that, we should create a prototype to show the flow of web site.Many prototype we can use such as application software ,paper and other method to create a prototype.
