Brute force An Attacker Can Perform The Hacking Technic Until Broke The Authentications. Like Combinations of username and password For Enter The Site Or Software until  Find The Username and Password. In Modern Days It Can Strictly Prohibited But Some Sites Still Run With That Bugs. SQL Injection In This Bug May Be Found By Programmer Careless Coding.In The Hacking Technic Must Performed By SQL Query. An Attacker Can Attack The Sites For SQL Queries And Retrieve Required Data From Database or Modify The Data Bases.  shop Xss(Cross Site Scripting) Now Popular Sites Are Affected By This Bug.Its Preformed By JavaScript Coding. An Attacker Modify The Client Side Programming It May Be Affect The Entire Web Site. Phishing It is Trick. An Attacker Can Be Develop The Front-End Application Look Like Original Web Page . It s a Clone Not Original. Some User Can Provide the Information on That Phishing Site. Hacker Can Using Them.  Key Logger Which is a Hidden Application on Your Co...

This Proposed By R.W. Royce in 1970. it is sequential design process. downwards it is basic SDLC Model. divided the life cycle due to set of phases. Each Phases Must be completed before the next phases can begin.. output of one phases can be input of one phases. No Overlapping. Feasibility study Determine weather if would be financially & technically feasible. Requirement Understanding the exact Requirement of the custom. Requirement Gathering Requirement Specification Design To Transform The Requirement Specification in The SRS document into Structure. Coding Design is  Translated into Source Code. Integrated Testing all The Module Successfully have been successfully integrated the full working system in up timed. Alpha Testing - Performed By Development Team.

Inheritance is a future of oops(Object Oriented Programming).it Used To Share The Properties of Class or a class drive from another one class is Called Inheritance. in Java Programming "extends" Keyword is used to inherit the class. Syntax: class A{ //member variables and function } class B extends class A { //member variables and function } example, class A{ void superclass() { System.out.println("super class"); } } class B extends class A { public static void main() { B b=new B(); b.superclass(); } } From The Above Java Programming Contains Two Classes Named As "A" and "B".class A contains a Member Method Named as "superclass()" and class B contains main method.then class B is Inherit(Extends) From class A.So We are call The method superclass from class B.

Class is a collection of similar objects. Which have common properties. Syntax class class_name {        //member functions and variables. } How to create a objects for class class_name c=new class_name; We can access the member variable and member methods using dot operator. c.member_function(); Eg : class bike { void fun() { System.out.println("member method"); } public static void main(String[] args) { bike B=new bike(); B.fun(); } } output member method

Method is a block of code. Its used to divide the large programs into small pieces. It is reusable. Syntax class class-name { public static void main(String[] args) { System.out.println("main method"); } public static void method () { System.out.println("method"); } } Uses of method 1.chunk programs. 2.reusable. 3.easy to debugging. Method overload Same method with different arguments is called method overload. class bike { void fun() { System.out.println("method with out parameter :"); } void fun(int a) { System.out.println("method with parameter : "+a); } public static void main(String[] args) { bike B=new bike(); B.fun(); B.fun(5); } } Output method with out parameter : method with parameter : 5

1.Physical Layer Physical layer coordinates the require electronic components or functions to Transmit data between computer systems.              1.Physical character sticks               2.Bit Rate 2.Data Link Layer Data Link Layer Convert the Physical Binary Data Form Into Frames. A Combination of Bit Rate is Called Frame. 3.Network Layer It is Responsible For Source To Designation Delivery Of Pockets. Which Contains Logical Address To Identify The sender and Receiver. 4.Transport Layer Its Transport The Data Into Network. 5.Session Layer Its establish,maintain and synchronous between communicate systems. Its Manage The Transmission Data Time Between Two or More Systems. 6.Presentation Layer It is Convert Transport Data Into Application Data. Interface Between Transport Layer And Application Layer. 7.Application Layer 7 Th Layer Of OSI(Open System InterFace) model. Which Provide The Data To User Interface.

Autonomous Computers are Inter connected. (or) Connected Computers are used to interchange The data or communication is called Network. Network Software A Software Which is Used to Communicate or Transmit The between Multiple Systems. Network Protocols HTTP->Hyper Text Transmission Protocol FTP->File Transfer Protocol TCP->Transmission Protocol UDP VoP-> Voice Over Protocol SMTP->Simple Mail Transfer Protocol STP->Secure TRansfer Protocol
