Difference Between Video Conference And Web Conference

December 29th, 2011 Comments off

Meetings are one of the most important activities in Business houses, because any important decision related to business can be taken after arranging proper discussion among the important authorities of that particular organization. Now a days many organizations have placed their business houses at different geographical locations to work as branch offices and this is very necessary especially for multinational companies. Regular communication is very important among these branches situated miles away from each other, telephonic communication and communication through Internet services are vastly used for this purpose but old technologies were allowing just two people to communicate at the same time with each other and it was not possible to bring more than two people in such a discussion. Web Conferencing is the technology, introduced to overcome this limited number of people’s ability to participate in a meeting held at a far away location.

Web conference allows multiple persons to interact with each other being situated at any place(with the availability of internet, software and required hardware for conference) in the world. Now a days due to new invention in conference technology people can not only communicate but also can see each other on screen (real-time) while the conference is being carried out, this is called Video Conferencing. Web conferences are more popular among professional business houses for simple oral communication but when you need to represent any images, videos which contain different surveys, numbers and graphs then video conference is most effective to share this kind of data among all attendees. Furthermore looking each other while communication creates a special psychological effect over the people in communication with each other. Video conference also plays an important role in different types of scientific projects where a person need to share his experiments visually among multiple people.

An Overview of XML – Part 2

Since XML is a very vast subject, while you study it and that’s the reason why this is one more post is needed to be written of its review. In this post you can find description of remaining features of XML, after we looked at ‘What is XML and how it is structured in previous post (An Overview of XML – Part 1)

While implementing XML you will always feel that it helps a lot of data sharing options. From a web developer’s point of view this is very positive aspect of XML because for the smooth function of a website you always need such type of data sharing among various web applications, which hold data in different structures. Due to XML this sharing can be made easy for the developers. Because every applicaton’s data structure can be mapped upon XML structure all the applications can share data in a common XML format.

An XML file can be read by human but still it’s not an interesting and easy task to do so. Being free of cost is a positive aspect of XML, it can be written with a simple text editor and tools like ‘XML Notepad’ are available fro free of cost. XML is supported by default by the web development application like Dreamweaver and Visual Studio .NET. If one want to parse it then Microsoft also provide a tool named with ‘MSXML’. XML is also usable with almost all of the leading CMS (Content Management Systems), XML documents are mostly used for storing the content which can be further transformed to provide the output on Web. The advantage of XML while transforming such data is that it make makes all changes to content to be contained at a central location and it is cascaded out in all formats required.

XML stands for ‘eXtensible Markup Language’, a meta-language which is used to create other languages. In XML data remains marked up with tags, somewhat similar to HTML tags. Interestingly, the recently launched HTML version is called XHTML, which is based on XML and follows the syntax rules set in XML.

XML is mainly intended to be used for the purpose of storing data and information. This data further can be read mostly by machines and on a few occasions by humans also. This data is mostly stored in databases and it can be also stored in normal spreadsheets but one more specialty XML has that it can also store data in loosely structured manner i.e. data stored in letters or manuals.

Despite being very useful XML is found lagging behind the other competitive technologies like HTML. When you see a HTML page through your browser it is a nice thing and this is something XML misses out, one really needs to work very hard to make a XML document exciting. The main feature of XML is to store the data in databases and spreadsheets, so that applications can use it for various processes. There are very few areas, where XML has a supremacy over its competitors like it has its own separate structure of formatting where as HTML documents, word processor documents, spreadsheets have some mess-up because of mix structures with formatting which makes things difficult to handle content and design of a webpage. In XML certain predefined tags used for emphasizing can be placed in <em> tags for some other purpose, because a XML document never define that how the content of the particular tag should be displayed and the formatting part is left to an external stylesheet.
