With HTML5, it is possible for the web pages to store the data locally in the user's browser. This web storage is much faster and secured than the cookies. Also, a larger amount of data can be stored without causing any adverse effect to the performance of the website. 

The data here is not included with every server request. It is used ONLY when it is asked for. It is only that particular web page that can access the data stored by itself.

Android Application Architecture has the following components:

> Services - like Network Operation

> Intent - To perform inter-communication between activities or services

> Resource Externalization - such as strings and graphics

> Notification signaling users - light, sound, icon, notification, dialog etc.

> Content Providers - They share data between applications

The web hosting on the server can be accomplished by using the IP based hosting that provides resources and services as follows:

- IP based hosting provides dedicated IPs that consists of virtual hosts and having the different IP address. 

- Web server is configured with different and multiple physical network interfaces using the same physical interface. 

- Web server uses this IP address to connect the client with the server to determine the web site that provides the client a view of it. 

- IP addresses provide the resources that are required in order to use the SSL certificates and other resources rather than shared certificate.

Security features are very essential in the system as it provides an overall security of the system by applying the patches and the services that keeps the unwanted access away.

- Use of algorithms in relation to, the security and the system to, solve the problem of the security. 

- Use of SSL or any encryption method to, protect the system from intrusion or any other attack.
