Correlation function is used to find the relationship between two variables.

• Correlation function measures the strength of the linear relationship between two variables.

• It returns a value between -1 and 1, where -1 indicates a perfect negative correlation, 0 indicates no correlation, and 1 indicates a perfect positive correlation.

• Examples of correlation functions include Pearson correlation coefficient, Spearman's rank ...read more

Correlation is a statistical measure that shows the relationship between two variables.

• Correlation measures the strength and direction of the relationship between two variables.

• It ranges from -1 to 1, where -1 indicates a perfect negative correlation, 0 indicates no correlation, and 1 indicates a perfect positive correlation.

• Correlation does not imply causation.

Various tools are used in Penetration Testing (PT) such as Nmap, Metasploit, Burp Suite, Wireshark, etc.

• Nmap is used for network scanning and mapping

• Metasploit is used for exploiting vulnerabilities

• Burp Suite is used for web application testing

• Wireshark is used for network traffic analysis

• Other tools like Nessus, Acunetix, etc. are also used depending on the requirements

Software Testing Life Cycle (STLC) is a process followed to ensure quality in software development.

• STLC includes planning, designing, executing, and reporting phases.

• It starts with requirement analysis and ends with post-release testing.

• STLC ensures that the software meets the specified requirements and is bug-free.

• It involves various types of testing such as unit testing, integration testing, system testing, and accep...read more

Polymorphism is the ability of an object to take on many forms. It allows objects of different classes to be treated as the same type.

• Polymorphism is a fundamental concept in object-oriented programming.

• It enables code reusability and flexibility.

• Polymorphism can be achieved through method overriding and method overloading.

• Example: A parent class Animal can have multiple child classes like Dog, Cat, and Bird. They can ...read more

StringBuilder is a class in Java that allows for efficient manipulation of strings.

• StringBuilder is mutable, meaning that it can be modified without creating a new object.

• It is more efficient than concatenating strings using the '+' operator.

• StringBuilder methods include append(), insert(), delete(), and replace().

Inheritance is a mechanism in object-oriented programming where a new class is created by inheriting properties of an existing class.

• Inheritance allows a class to reuse code from another class.

• The existing class is called the parent class or superclass, and the new class is called the child class or subclass.

• The child class inherits all the properties and methods of the parent class.

• The child class can also add new pro...read more

Abstraction is the process of hiding complex details and presenting only the essential features of an object or system.

• Abstraction helps in reducing complexity and making things easier to understand.

• It allows us to focus on the important aspects of an object or system.

• For example, a car can be abstracted as a mode of transportation without going into the details of its internal workings.

• Abstraction is used in programmi...read more
