Q. 1. Differentiate between TCP and UDP

Answer:TCP and UDP are two transport layer protocols, which are extensively used in internet for transmitting data between one host to another. Good knowledge of how TCP and UDP works is essential for any programmer. That's why difference between TCP and UDP is one of the most popular programming interview question. I have seen this question many times on various Java interviews , especially for server side Java developer positions. Since FIX (Financial Information Exchange) protocol is also a TCP based protocol, several investment banks, hedge funds, and exchange solution provider looks for Java developer with good knowledge of TCP

Q. 2. Describe briefly about Event Handling and Data binding

Answer:Event Handling:Most programs, to be useful, must respond to commands from the user. To do so, Java programs rely on events that describe user actions. The event-handling techniques we've seen so far in this chapter are part of the Level 0 DOM: the de facto standard API that is supported by every JavaScript-enabled browser. The DOM Level 2 standard defines an advanced event-handling API that is significantly different (and quite a bit

Q. 3. Write short notes on:

a) XPointer: XPointer is a language for locating data within an Extensible Markup Language (XML) document based on properties such as location within the document, character content, and attribute values. XPointer

b) XML Scripting

Answer: XML Script and XML-Script are two unrelated XML technologies. The former (XML Script) is an XML transformation language, while the latter (XML-Script) is a Microsoft technology preview for scripting web browsers - think of it as an XML version of ECMA JavaScript. Microsoft is expected to rename their XML-Script as Atlas Script

Q. 4. Write short notes on:

a) DOM: The Document Object Model (DOM) is a programming API for HTML and XML documents. It defines the logical structure of documents and the way a document is accessed and manipulated. In the DOM specification, the term "document" is used in the broad sense - increasingly, XML is being used as a way of representing many different

b) SAX: SAX (Simple API for XML) is an application program interface (API) that allows a programmer to interpret a Web file that uses the Extensible Markup Language (XML) - that is, a Web file that describes a collection of data. SAX is an alternative to using the Document Object Model (DOM) to interpret the XML file. As its name suggests, it's a simpler interface than DOM and is appropriate where many or very large files are to be processed, but it contains

Q. 5. Describe about Numeric and Associative PHP Arrays.

Answer: Array is one of the most vital part in every programming languages. It is also important to know what facilities and built-in functionality a programming language provides. PHP provides a very strong set of such efficient ways to deal with array data type. Time to time, I have discovered several usage of PHP arrays which not only saved my time but also made writing efficient code. I still often need to revisit these functions to memorize and use again. In this article,

Q. 6. Describe about ASP.

Answer: ASP.NET is a unified Web development model that includes the services necessary for you to build enterprise-class Web applications with a minimum of coding. ASP.NET is part of the .NET Framework, and when coding ASP.NET applications you have access to classes in the .NET Framework. You can code your applications in any language compatible with the common language runtime (CLR), including Microsoft Visual Basic and C#. These
