Question Discussion & Solution

The correct answer is World Wide Web.

Key Points

• Web service is a standardized medium to propagate communication between the client and server applications on the WWW (World Wide Web). 
  • A web service is a software system that supports interoperable machine-to-machine interaction over a network.
  • It has an interface described in a machine-processable format (specifically, Web Service Definition Language, or WSDL).
  • Web services fulfil a specific task or a set of tasks.
  • The nature of the interface hides the implementation details of the service so that it can be used independently of the hardware or software platform on which it is implemented and independently of the programming language in which it is written.

Additional Information

• A protocol is a set of rules or procedures for transmitting data between electronic devices, such as computers.
• The protocol that is used for transferring both text and binary files over the Internet is File Transfer Protocol (FTP).
• Hypertext Transfer Protocol (HTTP) is a protocol for transmitting hypermedia documents, such as HTML.
• Hypertext Transfer Protocol Secure (HTTPS) is a secure version of the HTTP protocol that uses encryption and authentication.

The correct answer is Cancer.

Concept: 

Infectious diseases:

• Infectious disease are diseases caused by bacteria, fungi, viruses, or parasites.
• Infectious diseases are transmitted by infectious agents.
• Infectious disease is spread by humans, plants, and insects. 
• Agents that spread pathogens or pass them on are known as vectors or disease intermediaries.

Explanation:

• Cancer is not an infectious disease. 
• Cancer cannot be passed from one person to another by breathing the same air, sharing a toothbrush, touching.
• Cancer is a disorder in which cell growth is uncontrolled.
• Changes in genes that control how our cells function, particularly how they grow and divide, cause cancer.
• Accelerating cell division rates or inhibiting normal control can result in gene mutations. 
• Cancer is sometimes caused by the genes we inherit from our parents.
• Cancer's Causes
  • Carcinogens such as tobacco, chemicals, alcohol, and ultraviolet radiation from the sun are among the leading causes of cancer.

Additional Information

• Cholera:
  • Cholera is a severe diarrheal infectious disease caused by Vibrio cholerae bacteria.
  • People who consume cholera-contaminated food or water may become ill.
  • The infection is frequently mild or without symptoms, but it can also be severe and life-threatening.
  • The disease's deadly effects are caused by a toxin produced by bacteria in the small intestine.
• TB (Tuberculosis):
  • Tuberculosis (TB) is an infectious disease caused by a Mycobacterium tuberculosis bacteria.
  • It was transmitted from person to person via microscopic droplets released into the air.

Explanation:

• The purpose of regression testing is to confirm that a recent program or code change has not adversely affected existing features.
• Regression testing is nothing but a full or partial selection of already executed test cases that are re-executed to ensure existing functionalities work fine.
• This testing is done to make sure that new code changes should not have side effects on the existing functionalities. It ensures that the old code still works once the new code changes are done.

The purpose of regression testing is to select test cases partially or fully to ensure existing functionalities work fine. Thus, regression testing is primarily related to functional testing

Need of Regression Testing

• Regression Testing is required when there is a change in requirements and code is modified according to the requirement or when one of the following has been done.
  • New feature is added to the software
  • Defect fixing
  • Performance issue fix
