What is Protocol?

What is an attribute?

What are properties?How page elements (whether it is heading or a block of codes) should be displayed in page is describe by property. Two main section of selector are selector and value.
o Selector {property:value}

What is an Element?
An element is anything that you define with HTML tags.
Tags tend not to do much more than mark the beginning and end of an element. Elements are the bits that make up web pages. You would say, for example, that everything that is in-between and includes the and tags is the body element. As another example, whereas '' are tags, '' is a title element.

What is Function?
A function is a rule which relates the values of one variable quantity to the values of another variable quantity. A function contains code that will be executed by an event or by a call to the function. You may call a function from anywhere within a page (or even from other pages if the function is embedded in an external .js file).
Functions can be defined both in the and in the section of a document. However, to assure that a function is read/loaded by the browser before it is called, it could be wise to put functions in the section

What is OOP?
Object oriented programming is a technique for programming – a paradigm for writing ‘‘good’’ programs for a set of problems. OOP is programming which is oriented around objects, thus taking advantage of Encapsulation, Polymorphism, and Inheritance to increase code reuse and decrease code maintenance.
Object Oriented Programming enables you to put data and functions in one container. This container is referred to as an object. An object enables you to model your application as closely as possible to the real world

What is an object?
An object is contains methods and attributes and data that work together. Objects are usually grouped into classes. A class contains objects that all have the same operations or methods behaving in the same way and attributes or properties representing the same things.
OBJECT-ORIENTATION is a set of tools and methods that enable software engineers to build reliable, user friendly, maintainable, well documented, reusable software systems that fulfills the requirements of its users

What is Java Script?
JavaScript is a client-side language that adds interactivity and conditional behavior to a web page. With java script you can display additional information about links, create mouse hover effects, change the contents of the page based on certain condition. JavaScript works with HTML to bring interactivity to otherwise static documents.
Java Script can be embedded inside HTML documents in three ways. -The code is placed between tags. -Code is included inside an HTML tag. -The entire code is placed in another file, which is called through the SRC.

What is ASP.NET?
ASP.NET is a web application framework. A Web server technology for dynamically rendering HTML pages using a combination of HTML, Javascript, CSS, and server-side logic.

What is Web Service?
Web services allow different applications from different sources to communicate with each other. The standard XML technologies normally used in web services include SOAP, WSDL, UDDI and XSD. Web services are not tied to any one operating system or programming language. For example, Java can talk with Perl, Windows applications can talk with UNIX applications

What is API?
An API,.. 'application programming interface' is a way for website or service to talk to another website or service. APIs let you mix information and media from other services into your own site or application.
Example: The Blogger Data API allows client applications to view and update Blogger content. Your client application can use the Data API to create new blog posts, edit or delete existing posts, and query for posts that match particular criteria. API uses Protocol and technologies like SOAP, JavaScript, and XML

What is CSS?
CSS is a web page styling language that describes how to present certain element in a web page. It works together with HTML.

CSS is separate and defines the element's style. Stylistic properties are about how the element looks, such as its size, position, color, and font. Web developers can design page lay out, sizing and positioning of elements, with the help of CSS.

What is .NET?
The .NET Framework is Microsoft's application development platform that enables developers to easily create Windows applications, web applications, and web services using a myriad of different programming languages, and without having to worry about low-level details like memory management and processor-specific instructions.

What is Virtual Server?
Virtual Server is a server application that enables users to run a range of OS, environment simultaneously on a single physical server. From testing perspective it is very useful to create quick test environment with different configurations value. Once test is completed, tester can discard that environment and can go to base line environment and create new environment for other testing. My experience is with Installation and deployment environment. I had created a baseline environment to testing installation MSI, after running MSI once, it was not possible for me to delete everything manually such as folder, register key…….. but With the help of virtual server I can discard go back to my baseline environments in no time and I am ready to test next build.
