Software Testing Ppt (Theory), Assignments of Software Engineering

Amity Business School Software Engineering

Software Testing is a method to check whether the actual software product matches expected requirements and to ensure that software product is Defect free. It involves execution of software/system components using manual or automated tools to evaluate one or more properties of interest. The purpose of software testing is to identify errors, gaps or missing requirements in contrast to actual requirements.

Internet:

The Internet is the worldwide, publicly

accessible network of interconnected

computer networks that transmit data by

packet switching using the standard

Internet Protocol (IP). It is a "network of

networks" that consists of millions of

smaller domestic, academic, business, and

government networks, which together

carry various information and services,

such as electronic mail, online chat, file

transfer, and the interlinked Web pages

and other documents of the World Wide

Web.

 Architecture of Internet :-- The Internet's architecture

is described in its name, a short from of the compound

word "inter-networking". This architecture is based in

the very specification of the standard TCP/IP protocol,

designed to connect any two networks which may be

very different in internal hardware, software, and

technical design. Once two networks are

interconnected, communication with TCP/IP is enabled

end-to-end, so that any node on the Internet has the

near magical ability to communicate with any other no

matter where they are. This openness of design has

enabled the Internet architecture to grow to a global

scale.

Architecture of Internet :--

 Intranet:

 A network based on TCP/IP protocols (an internet)

belonging to an organization, usually a

corporation, accessible only by the organization's

members, employees, or others with authorization.

An intranet's Web sites look and act just like any

other Web sites, but the firewall surrounding an

intranet fends off unauthorized access.

 Like the Internet itself, intranets are used to share

information. Secure intranets are now the fastest-

growing segment of the Internet because they are

much less expensive to build and manage than

private networks based on proprietary protocols.

 Architecture of Intranet :-

 Characteristics of Intranet :--

-- Below seven characteristics fundamental to a successful Intranet.

1. Communication – The intranet must support various

communication channels, such as information from the

management team concerning strategic aspects of their

organisation or collaboration amongst project teams and

departments. These formal and informal methods of

communication are equally important. Therefore essential to

have an in-depth look at the communication tools on offer.

2. Maintenance and Updating – It is inevitable that your

intranet will require frequent updating and maintenance to

ensure that the information provided is both relevant and

accurate. Adding an image or changing content should not be

a difficult process, nor should it be time-consuming.

Surprisingly, many intranet systems require the help of

technically skilled people to perform these tasks.

6. Access flexibility – Accessibility by either a laptop or desktop is no longer acceptable, as not all employees perform tasks and activities at their desks. Certain job roles require employees to visit clients, and regular off-site meetings are becoming more common. Therefore flexibility in accessing their intranet on mobile devices and tablets should facilitate and not compromise their ability to perform tasks on their intranet. 7. Online Workspace – It is important to think about the functions and daily tasks carried out by each department within your organization, as each department varies considerably in terms of what they need to successfully do their job.

 Application of Intranet :--

1. Document publication applications :-

The first application that always comes to mind for

intranets in and of themselves is the publication

and distribution of documents. This application

allows for paperless publication of any business

information that is needed for internal employees

or external customers or suppliers. Any type of

document may be published on an intranet: policy

and procedure manuals, employee benefits,

software user guides, online help, training manuals,

vacancy announcements--the list goes on to include

any company documentation.

3. Interactive communication applications :--

Two-way communications and collaboration on

projects, papers, and topics of interest become

easy across the intranet. Types of communications

that are enhanced and facilitated include e-mail,

group document review, and use of groupware for

developing new products.

4. Support for Internet applications :--

Even though organizational full-service intranets

are the next step in enterprise-wide computing and

have enough value to make them desirable simply

for the organizational benefits they bring, they are

also necessary for supporting any Internet

applications that are built.

 Extranet:

 An extranet is a private network that uses Internet

technology and the public telecommunication

system to securely share part of a business's

information or operations with suppliers, vendors,

partners, customers, or other businesses. An

extranet can be viewed as part of a company's

intranet that is extended to users outside the

company. It has also been described as a "state of

mind" in which the Internet is perceived as a way

to do business with other companies as well as to

sell products to customers.

Architectures of Extranet :--

 Extranet System Architecture

 Extranet

 (^) Connects two or more business partners  (^) Like an intranet  (^) Same software, hardware, and networking  (^) Additional component:  (^) Virtual Private Network (VPN)  (^) Secure transmission of proprietary info

Architecture of Extranet :-

 (^) Just as intranets provide increased internal collaboration, extranets provide increased efficiencies between your company and its customers and/or suppliers. Developing and implementing an extranet application can provide you the competitive edge to stay ahead of the competition in the eyes of your customers and a better ability to negotiate prices with your suppliers.  (^) Extranet Applications :--

Supply-chain management
Customer communications
Distributor promotions
Online continuing education/training
Customer service
Order status inquiry
Inventory inquiry
Account status inquiry
Warranty registration
Claims
Online discussion forums

 EXTRANET CHARACTERISTICS :--

1. Information Sharing :-- Sharing information is an important feature of an extranet. Different types of industries find that this streamlines work and increases productivity. For example, a large building project usually involves several companies. The project management company can put all the relevant project documents on its extranet so that the other partners can access them. This ensures that each business has equal access to information -- and cuts down on printing and circulating documents to all the parties. Manufacturing businesses are another example. They can put technical specifications for parts suppliers on an extranet, which a supplier can easily and quickly check.
