The Importance Of Web Application

A Document Object Model (DOM) is a API (application protocol interface) used in HTML and

A RESTful API defines a set of functions that developers can use to perform requests and receive responses via HTTP protocol, such as GET and POST. Because RESTful APIs use HTTP as a transport, they can be used by practically any programming language and are easy to test. It’s a requirement of a RESTful API that the client and server are loosely coupled and independent of each other, allowing

The OSI (Open System Interconnection) model is a set of specifications that allow computers around the world to openly communicate. It is pivotal to understanding and developing computer to computer communications in a network. Each layer plays a role in the process of sending and receiving data. The application layer is the top layer (layer seven) it promotes communication between programs and lower-layer network services. The services at this layer allow the network to decipher a program's request and the program to decipher data sent from the network. The Application layer protocols, programs handles formatting, procedure, security, synchronization, and any other requirements with the network. The Presentation Layer (layer 6) acts as a translator. For instance these protocols decode the jpg/jpeg files sent within the Web server’s HTTP response. So, in the last step (the Application layer) we enter the Web address and it took us to the Web site. This step allows us to see the images and content of the site. The Session Layer (layer 5) regulates and controls the communication between two nodes on the network. It is an ongoing exchange of data between the two and keeps the connection between them for the duration. It keeps the communication secure, detects whether or not the communication has been cut off and if it has it determines where to restart the

We can create a controller object to handle the REST requests (GET, POST). In this controller we can use action routing [48] to control which function will handle which request. In every function, we can do some computations with the data, make decisions and use the HTTP web client to construct and send responses to the partner end point URLs.

Created web.xml for characterizing the servlets and to handle the solicitations for the particular URL designs and characterized load on start-up quality to stack the different properties record when server is begun.

In the past native applications had some capabilities which were missing in the web area. This function can store data on the client. This is the good way to replace cookies. An alternative proposed by the World Wide Web Consortium (W3C) is called Web Storage. The Web Storage contain of Local Storage, so I will explain the Local Storage here.

1.Basic Authentication- Basic authentication is one of the two mechanisms in HTTP 1.1 specification . It required the safe http communication i.e. https communication for encoding.

Chapter 4: “Communication with server using AngularJS”, focus on how AngularJS communicate with server side code such as Web API, Web Services or Data Access Layer (DAL). In this chapter we will discuss how to retrieve data form server using $http, $resources. This chapter also talk about the authentication and security for AngularJS application. This chapter organized as follow.

The first protocol explain is TCP. Starting with the Layer 7, 6, and 5, the Application Layer is providing the payload (data and instructions). The web browser is an example of initiation of Layers 7,6,5 and the payload flow. The Transport

The difference is that a URI can be used to describe a file's name or location, or both, while a URL specifically defines a resource's location.

Requests a URI over the Apache JServ Protocol and displays the result (or stores it in a file). Different AJP methods such as; GET, HEAD, TRACE, PUT or DELETE may be used.

The application layer: this layer allows different applications to communicate with each other’s. In order to exchange different data over the network connection, the protocols included in this layer set up the standards such as DNS, HTTP, FTP. The data coded in this layer will be encapsulated to transport layer for further packing.

URL (Uniform Resource Locator, previously Universal Resource Locator) is the unique address for a file that accessible on the Internet, is a reference to a web resource that specifies its location on a computer network and a mechanism for retrieving it. (Rouse)

Its implementation will require knowledge in development and could therefore prove costly to businesses. To summarize, the Accelerated Mobile Pages (AMP) use an HTML framework that was designed to reduce page loading time, reduce data consumption and improve the mobile user experience. This is the charm of AMP, unlike an HTTPS deployment, AMP can be deployed page by page.

Generally, an URL has two major components: the first part “Protocol Identifier” and the second part “Resource name”. The Protocol Identifier represents the name of the protocol to be used to achieve the resource. In addition to the commonest one for web pages – Hypertext Transfer Protocol (HTTP) that is typically used to serve up hypertext documents, there are many different protocols used to access different types of resources on the internet, such as File Transfer Protocol (FTP) for file transfer, MAILTO for email features, JDBC for database access and many other applications.
