UML - PART II


UML
Unified Modeling Language (UML) is a standardized specification language for object modeling. UML is a general-purpose modeling language that includes a graphical notation used to create an abstract model of a system, referred to as a UML model.
UML is officially defined at the Object Management Group (OMG) by the UML metamodel, a Meta-Object Facility metamodel (MOF). Like other MOF-based specifications, the UML metamodel and UML models may be serialized in XMI. UML was designed to specify, visualize, construct, and document software-intensive systems.
UML is not restricted to modeling software. UML is also used for business process modeling, systems engineering modeling, and representing organizational structures. The Systems Modeling Language (SysML) is a Domain-Specific Modeling language for systems engineering that is defined as aUML 2.0 profile.

TCP/IP - PART II


TCP/IP
TCP/IP is a communications protocol used to transfer digital data around the internet.
TCP and IP were developed by a Department of Defense (DOD) research project to connect different networks designed by different vendors into a network of networks (the "Internet").TCP/IP is often referred to as the 'internet protocol'.
TCP/IP stands for Transmission Control Protocol/Internet Protocol. If this leads you to think that it is not just one protocol, you’re right. In fact, it is not just two protocols, either. TCP/IP is a suite of protocols.
IP is the bedrock protocol of TCP/ IP. Every message and every piece of data sent over any TCP/ IP network is sent as an IP packet.
IP’s job is to enable data to be transmitted across and between networks. Hence the name: inter- net protocol.

Inside BIOS


Inside BIOS
Basic Input/Output System also incorrectly known as Basic Integrated Operating System and occasionally Built In Operating System.
BIOS refers to the firmware code run by an IBM compatible PC when first powered on.
The primary function of the BIOS is to prepare the machine so other software programs stored on various media (such as hard drives, floppies, and CDs) can load, execute, and assume control of the PC.
This process is known as booting up.
BIOS The set of routines stored in read-only memory that enable a computer to start the operating system and to communicate with the various devices in the system, such as disk drives, keyboard, monitor, printer, and communications ports.

Inside Operating System


Inside Operating System
An Operating System is the software that controls the operation of a computer, directs the input and output of data, keeps track of files, and controls the processing of computer programs.
Its roles include managing the functioning of the computerhardware, running the applications programs, serving as an interface between the computer and the user, and allocating computer resources to various functions. Through a process called time-sharing, a large computer can handle interaction with hundreds of users simultaneously, giving each the perception of being the sole user.
When several jobs reside in the computer simultaneously and share resources (multitasking), the OS allocates fixed amounts of CPU time and memory in turn or allows one job to read data while another writes to a printer and still another performs computations.
Operating systems offer a number of services to application programs and users. Applications access these services through application programming interfaces (APIs) or system calls. By invoking these interfaces, the application can request a service from the operating systempass parameters, and receive the results of the operation.
For hand-held and desktop computers, the GUI is generally considered part of the operating system. For large multiuser systems, the GUI is generally implemented as an application program that runs outside the operating system.

jQuery
jQuery is great library for developing Ajax based application; It is also a great library for JavaScript script programmer, that makes it easy to create wonderful web effects in just a few lines of code . It was released in January 2006 at BarCamp NYC by John Resig.You can use jQuery to develop cool web 2.0 applicationsjQuery helps the programmers to keep code simple and concise. The jQuery library is designed to keep the things very simple and reusable.img
jQuery is java script and can be used with JSP, Servlets, ASP, PHP, CGI and almost all the web programming languages.
JQuery is nothing but simply call a JavaScript base library. It adds syntax to the JavaScript language to ease working with the DOM.

AJAX - PART II


AJAX
Ajax (shorthand for asynchronous JavaScript + XML) is a group of interrelated web development techniques used on the client-side to create interactive web applications. WithAjax, web applications can retrieve data from the server asynchronously in the background without interfering with the display and behavior of the existing page.The use ofAjax techniques has led to an increase in interactive or dynamic interfaces on web pages.
Data is usually retrieved using the XMLHttpRequest object. Despite the name, the use of JavaScript and XML is not actually required, nor do the requests need to be asynchronous.
The term Ajax has come to represent a broad group of web technologies that can be used to implement a web application that communicates with a server in the background, without interfering with the current state of the page.

VBScript - PART II


VBScript
VBScript is a scripting language. VBScript was created by Microsoft to use either as a client-side scripting language for the Microsoft Internet Explorer (versions 3.0 and later) or as a server-side scripting language with the Microsoft Internet Information Server (versions 3.0 and later).A primary advantage for using the server-side approach is that the VBScript is processed by the server before it is transmitted to the client.img
In our VBScript tutorial you will learn how to write VBScript, and how to insert these scripts into your HTML files to make your web pages more dynamic and interactive. VBScript Version 5.0 was released in 1999.
Certainly, the most important new feature of Version 5.0 is the ability to create your own class objects. Other new features included like the Timer function, With statement, and regular expression searching using the RegExp and Match objects.

WAP / WML - PART III


WAP/WML
WML (Wireless Markup Language) is the new web language for making sites on mobile phones.
Over the past few months new WAP (Wireless Applications Protocol) phones have become extremely popular and many large websites have created special 'mobile' versions of their site.
Many people predict that, over the next few years, WAP sites will become even morepopular and e-commerce over mobile phones will be widely available.
Wireless Markup Language(WML) based on XML, is a content format for devices that implement the Wireless Application Protocol (WAP) specification, such as mobile phones, and preceded the use of other markup languages now used with WAP, such asXHTML and even standard HTML (which are gaining in popularity as processing power in mobile devices increases).

XML Schema - PART III


XML Schema
The definition of an XML document, which includes the XML tags and their interrelationships. Residing within the document itself, an XML schema may be used to verify the integrity of the content.
Various recommendations for an XML schema were submitted to theW3C, and a standard was approved in May 2001 that included the ability to define data by type (date, integer, etc.).
An XML schema is a description of a type of XML document, typically expressed in terms of constraints on the structure and content of documents of that type, above and beyond the basic syntax constraints imposed by XML itself.
Through a process called time-sharing, a large computer can handle interaction with hundreds of users simultaneously, giving each the perception of being the sole user.
An XML schema provides a view of the document type at a relatively high level of abstraction.

XSL - PART VI


XSL
EXtensible Stylesheet Language(XSL) is an standard from theW3C for describing a style sheet for XML documents. It is the XMLcounterpart to the Cascading Style Sheets (CSS) in HTML and is compatible with CSS2.
XSL is made up of three components: (1) XSL Transformations (XSLT) is the processing language for XSL. It is used to convert XML documents into HTML or other document types and may be used independently of XSL. (2) XML Path Language (XPath) is used to identify and select tagged elements within an XML document, and (3)XSL Formatting Objects (XSL-FO) provides the format vocabulary.
An XSLT is the transformation language, which lets you define a transformation from XMLinto some other format.
For example, you might use XSLT to produce HTML or a different XML structure. You could even use it to produce plain text or to put the information in some other document format.
