The risks of Automation Testing are:

1. Do you have skilled resources?

The automation testing demands resources with some knowledge about programming. Focus on the resources. Identify whether the resources have proper knowledge for automation testing. Are they capable to adapt easily to the new technologies? These measures are to be well assessed for building an automation testing team.

2. The initial cost for automation is high.

The initial cost for automation is too high for initial setup. It costs automated tool purchase, training ad maintenance of the test scripts. The unsatisfied customer base is high for automation testing their products. It should be ensured that the cost compensates the testing results.

3. If UI is not fixed, do not thing about automation:

Prior to automating the user interface, it should strongly be determined that, whether the UI is changing extensively or the cost of the automated script maintenance is high or not.

4. Make sure that the application is stable enough:

To automate the early development cycle unless or otherwise it is Agile environment, would not be a good idea. It costs script maintenance cost very high.

5. Stop automating the tests which run once:

Ensure that certain test cases might be running once and not included in the regression testing. Avoid automating such test modules.

various activities involved in project management

According software testing procedure the tester should be provided with software specification without understanding the procedure the tester is going to test nothing

Advantage: machines usually have lower cost per hour than people

Disadvantage: uncanny valley. People may find machines scary.

Software and traditional engineering are somewhat very closely related. Engineering practices like cost and effort estimation are common in both.

The testing phase consumes the maximum effort in waterfall model.

Thanks for asking such question and I hope this will be a helpful source answer for all. An agile project work is done in regularly iterated cycles, known as sprints which are beneficial for software delivery. Well, a proper frame work can be helpful in scrum so I must suggest tryScrum for getting an agile software development with scrum which can give you more success in software field.

A milestone is a point some way through a project plan that indicates how far the project has progressed.

1. Most modern sophisticated software is to big to fit on a single floppy disc/diskette.
2. It is simpler to burn a single CD than to create multiple diskettes. package and distribute them.
3. Most modern computers do not have the ability to read a floppy disc.

1.Each phase of an iteration is rigid with no overlaps

2.Costly system architecture or design issues may arise because not all requirements are gathered up front for the entire lifecycle

There is basically no difference between jpg and jpeg. They mean the same thing, and are exactly the same type of file. It's just a different name (extension) for the same thing.

However if you want to convert these type of images in bulk, ImageBadger Image Converter will help and save your time.

According to Simon (1977), Intelligence, Design, And Choice, known as IDC are the phases of Decision making process. In the intelligence phase, decision situation is studied, figure out severity of problem, ownership of the problem.

In the design phase, design of solutions for the problem is created. In the choice phase, one of the best solution from the different designed solutions are selected.

The Software development process is composed of many activities, notably the following. * Conception: Establishing a case model for the development of the software. * Requirements Analysis: Extracting the requirements of a desired software product is the first task in creating it. While customers probably believe they know what the software is to do, it is important to recognize incomplete, ambiguous or contradictory requirements. * Specification: Specification is the task of precisely describing the software to be written. What functions it should have, the user interface, and any other requirements. * Software architecture: The architecture of a software system refers to an abstract representation of that system. Architecture involves making sure the software system will meet the requirements of the product, as well as ensuring that future requirements can be addressed. The architecture step also addresses interfaces between the software system and other software products, as well as the underlying hardware and the operating system platform. * Implementation: Converting a design to functional code. * Testing: Testing all aspects of the software's functionality. * Documentation: An important task is documenting the internal design of software for the purpose of future maintenance and enhancement. * Software Training and Support: Users will have lots of questions and software problems which leads to the next phase of software. * Maintenance: Maintaining and enhancing software to cope with newly discovered problems or new requirements.

upgradation of old softwares. e.g- anti-viruses.

provides opportunities for new jobs and latest requiremants.

provides better interfacing between hardware & software.

Because it is a structured and systematic approach to building applications. Just like any other egineering discipline it has a planning stage

it has jargon and technical stages , it has conventions and measurement units. It involves the laying and combination of components , and he testing of their efficiency and sustainabibilty

The 8086/8088 has a clock oscillator circuit. You provide a crystal, and it will generate a clock signal that controls the speed of the processor. In that respect, it has a clock.

The 8086/8088, however, does not have a time of day or date clock. You can build a software entity that keeps day/date time using interrupts from a divider off of the clock oscillator but, that is not the same thing as a non-volatile clock chip such as provided in the PC, but which is not part of the 8086/8088.

MODEM stands for modulator/demodulator. Outgoing it modulates a carrier wave with information and transmits this data on a wire or through the air. When it receives a modulated signal it demodulates the signal and separates out the information.

if its already an ac y u need to convert!......Yes it need to change because in ac supply we need to change the frequency of current so ac to ac converter needed.The name of AC to AC converter is Regulator

The diagram for airline reservation system can be found by doing an internet search. It includes the day of the week and the flight.

Prototyping model is one of the software development life cycle model. In this we prepare a prototype before the actual product.

When we consider a modular solution to any problem, many levels of abstraction can be posed. At the highest level of abstraction, a solution is stated in broad terms using of the problem environment. At lower levels of abstraction, a mmore detailed description of the solution is provided.
