13.Object-oriented programming (OOP) is a programming paradigm that uses “objects” – data structures consisting of data fields and methods together with their interactions – to design applications and computer programs.

the main difference is that structured programming deals with the flow of execution, and not, primarily, with the data. The mathematical basis for structured programming has to do with the elimination of arbitrary jumps (GOTOs) in favor of code blocks and functions. In particular, “information hiding” as it relates to data isn’t fully developed in structured programming; structured programming has to do with the organization of the code, rather than the data, and pure structured programming passes data around in the form of function arguments (conceptually, “on the stack”).

In contrast, object oriented programming primarily deals with data issues. The object/class paradigm promotes clean, flexible organization of data in the same way that structured programming promotes clean, flexible organization of code. In a pure object oriented approach, the flow of program execution is treated as bits of behavior associated with the packets of data that are “objects”.

14. Java is a programming language originally developed by James Gosling at Sun Microsystems (which is now a subsidiary of Oracle Corporation) and released in 1995 as a core component of Sun Microsystems’ Java platform. The language derives much of its syntax from C and C++ but has a simpler object model and fewer low-level facilities. Java applications are typically compiled to bytecode (class file) that can run on any Java Virtual Machine (JVM) regardless of computer architecture. java has OOP facility that makes designing, creating, developing, and allocating a failure from Java-based program easier, faster, and more organized.

15. HTML, which stands for HyperText Markup Language, is the predominant markup language for web pages. It is written in the form of HTML elements consisting of “tags” surrounded by angle brackets within the web page content. It is the building blocks of all basic websites.
Extensible Markup Language (XML) is a set of rules for encoding documents in machine-readable form.

HTML is actually a loosely defined subset of XML. However, whereas XML is a strict language (as you will learn), HTML takes many liberties that have helped it become the popular presentation tool it is today. Although the spirit of the young Internet encouraged freedom, developers have now realized that the freedom of HTML has repercussions. Because HTML is so flexible, many browsers and Web applications have added their own functionality to the base HTML protocol. Like all enhanced functionality, this comes with additional security risks.

For this reason, efforts are underway to replace HTML with a much more regulated and standardized markup language known as XHTML.
