PAPER: WEB TECHNOLOGY

SECTION-A (10 X 2 = 20)

1.       What is the difference between node and host?

(ans: A node is any addressable device connected to a network whereas the host is a more specific descriptor that refers to a networked general-purpose computer rather than a single purpose device (such as a printer).)

2.       What is the purpose of routers?

(ans: This is a hardware device that routes data (hence the name) from a local area network (LAN) to another network connection. A router acts like a coin sorting machine, allowing only authorized machines to connect to other computer systems. Most routers also keep log files about the local network activity.)

3.        Define protocol.

(ans: When computers communicate with each other, there needs to be a common set of rules and instructions that each computer follows. A specific set of communication rules is called a protocol. Because of the many ways computers can communicate with each other, there are many different protocols .Some examples of these different protocols include PPP, TCP/IP, SLIP, HTTP, and FTP.)

4.        Define java server pages.

( ans : Java Server Pages (JSP) is a technology that helps software developers  create dynamically generated web pages based on , HTML or XML or other document types. To deploy and run Java server Pages, a compatible web server with a servlet container, such as Apache Tomcat,or Jetty is required.)

5.        What do you mean by web application?

(ans: A Web application is an application program that is stored on a remote server and delivered over the Internet through a browser interface.)

6.       What is meant by deploying the application to the server?

(ans: Deployment is a process of installing application into server context. It's different than "running the app" because a web application isn't simply run--it's run in the context of the container. A command-line Java application is run--it has no dependencies other than the JVM (and any external libraries it uses). A web application relies on the container to feed it requests, determine the application's context, and so on. )or(During the installation of a web application, after loading the JSP document in the subdirectory, the server have to be notified that a new web application is available. This step is known as deploying the application to the server.)

7.       What is IL?

(ans: IL code is a CPU independent partially compiled code. It's partially compiled because we do not know in what kind of environment .Net code will run and on runtime IL Code will compile to machine code using the environmental properties )

8.       What is a CLR?

(ans: The Common Language Runtime (CLR), the virtual machine component of Microsoft's .NET framework, manages the execution of .NET programs. A process known as just-in-time compilation converts compiled code into machine instructions which the computer's CPU then executes.)

9.       What is the role of server?

(ans: A server role is a set of software programs that, when they are installed and properly configured, lets a computer perform a specific function for multiple users or other computers within a network.)

10.   Define MIME.

(ans: MIME (Multi-Purpose Internet Mail Extensions) is an extension of the original Internet e-mail protocol that lets people use the protocol to exchange different kinds of data files on the Internet: audio, video, images, application programs, and other kinds, as well as the ASCII text handled in the original protocol, the Simple Mail Transfer Protocol (SMTP).)or( MIME (Multipurpose Internet Mail Extensions) is an open standard for sending multipart, multimedia data through Internet email.)

11.   What are servlets?

(ans: A small program that runs on a server, the term usually refers to a Java applet that runs within a Web server environment. This is analogous to a Java applet that runs within a Web browser environment. Java servlets are becoming increasingly popular as an alternative to CGI programs. The biggest difference between the two is that a Java applet is persistent)

12.   What do you mean by server-side?

(ans: Occurring on the server side of a client-server system. For example, on the World Wide Web, CGI scripts are server-side applications because they run on the Web server. In contrast, JavaScript scripts are client-side because they are executed by your browser (the client). Java applets can be either server-side or client- side depending on which computer (the server or the client) executes them.)
