A 32 bit processor is faster than a 64 bit processor, 64 bit processors are very commonly used that you can find it easily in any home pc but the main difference is the hardware you are having on your machine. For 32 bits there isn't any need of any wide main bus to carry 32 bits at a time but for 64 bits its must that you should have a wider bus to carry 64bits.

Android is a stack of software for mobile devices which has Operating System, middleware and some key applications. The application executes within its own process and its own instance of Dalvik Virtual Machine. Many Virtual Machines run efficiently by a DVM device. DVM executes Java language’s byte code which later transforms into .dex format files.

Features of Android :

- Components can be reused and replaced by the application framework.
- Optimized DVM for mobile devices
- SQLite enables to store the data in a structured manner.
- Supports GSM telephone and Bluetooth, WiFi, 3G and EDGE technologies
- The development is a combination of a device emulator, debugging tools, memory profiling and plug-in for Eclipse IDE.

Autostatus is a protocol mode which causes the expansion of each DML statement to include a 'perform IDMS-Status' statement.

- Web browser is used to run the software application that allows retrieving, presenting and traversing the information from one place to another. 

- Web browser provides the resources using the WWW (World Wide Web) this can be identified by URI (Uniform Resource Identifier).

- Web browser fetches the data like web page, image, video or other piece of content from the server and displays it accordingly. 

- Web browser uses hyperlinks to display the resources and allow the users to navigate their browsers according to the resources. 

- Web browser defines the application software that is designed for the user to access and retrieve the documents using the Internet.

There are some differences:

COBOL II supports structured programming by using in line Performs and explicit scope terminators. It introduces new features (EVALUATE, SET. TO TRUE, CALL BY CONTEXT, etc). It permits programs to be loaded and addressed above the 16-megabyte line .  It does not support many old features (READY TRACE, REPORT-WRITER, ISAM, etc.). It offers enhanced CICS support.

The foreground activity, being the most important among the other states, is only killed or terminated as a last resort, especially if it is already consuming too much memory. When a memory paging state has been reach by a foreground activity, then it is killed so that the user interface can retain its responsiveness to the user.

TCP-Transmission Control Protocol

UDP- user Datagram protocol

UDP is user assisted program and converts the application into the encapsulated form and makes it end point for data to send and then TCP helps in transmission or broadcast!

Contextual selector addresses specific occurrence of an element.
It is a string of individual selectors separated by white space (search pattern), where only the last element in the pattern is addressed providing it matches the specified contex.
