What is Linux?1.Linux is a Unix-like operating system.2.It was designed to provide personal computer users a free or very low-cost operating system comparable to traditional and usually more expensive Unix systems.3.Linux has a reputation as a very efficient and fast-performing system.4.Linux’s kernel (the central part of the operating system) was developed by Linux Torvalds at the University of Helsinki in Finland.

Linux - free softwareFree software, as defined by the FSF (Free Software Foundation), is a "matter of liberty, not price." To qualify as free software by FSF standards, you must be able to:

Run the program for any purpose you want to, rather than be restricted in what you can use it for. View the program's source code. Study the program's source code and modify it if you need to. Share the program with others. Improve the program and release those improvements so that others can use them.

Difference Windows & LinuxLinux:1.Linux is good for people who would like to learn more about computers.2.It is good for servers(most servers are Linux).3.It is the operating system of choice for supercomputers.4.Good for cheap old Hardware.

Windows:1.Windows is good for general office use,mainly because it runs Microsoft Office.2.Good for small networks.3.Good for Powerful all purpose servers. With Windows you run one server to do everything , with Linux you run 3-10 servers to do the same .4.Good for games and other real time applications.

What is Oracle?Oracle says it is the world’s supplier of software for information management but it is best known for its sophisticated relational database products.Oracle has long been a champion of network computers.It now boasts that it was the world’s first software company to develop and deploy 100 percent internet-enabled enterprise software across it’s entire product line ; database,server,enterprise business applications.

CreatingTable by Oracle 1.Oracle create table syntax defines the table name2.Oracle create table syntax defines the columns in the table and the data types of those columns.3.Oracle create table syntax defines what table space the table resides in.4.Oracle create table syntax defines other characteristics of the table Example:Connect scott/tiger CREATE TABLE books( book_id NUMBER PRIMARY KEY, book_name VARCHAR2(30), author_name VARCHAR2(40), book_isbn VARCHAR2(20) )TABLESPACE users;

What is WebLogic Server?WebLogic is a leading e-commerce online transaction processing (OLTP) platform , developed to connect users in a distributed computing environment and to facilitate the integration of mainframe applications with distrusted corporate data and applications.

What is a webLogic Sever Domain?

A WebLogic server domain is an administrative group of servers and clusters. You can configure ,administer, monitor and manage the WebLogic domain from a centralized location. The resource is the domain act as a unit.

What is Main Server?There isn’t just one main server for the entire internet, the internet is a community of networks and servers located around the world. Some of the servers have specific tasks,such as maintaining the DNS system. The internet is a distrusted network . As a result, there is no such thing as a “Main Server”.

What is J2EE?J2EE is a platform independent, java-centric from Sun for developing, building and developing Web-based enterprise applications online . The J2EE platform consists of a set of services , APIs , and protocols that provide the functionality for developing multitiered ,Web-based applications.

What is difference between JAVA and J2EE?JAVA: Java is a object-oriented program it’s a complete programming language . Java has two lives, one as a stand –alone computer language for general purpose programming and the other as a supporting language for internet programming.J2EE: J2EE is a platform for building server-side application . Its used for enterprise edition means a business organization , and enterprise application, distributed application through a component-based application model.

What is Java Servlet?The servlet is a Java programming language class used to extend the capabilities of a server. Although servlets can respond to any types of requests, they are commonly used to extend the applications hosted by web servers, so they can be thought of as Java applets that run on server instead of in web browsers.These kinds of servlets are the java counterpart to other dynamic Web content technologies such as PHPand ASP.NET.

What is Java Servlet Technology??

ExteApplications run on the server.And functionality of a web server and provide structure for a business environment.Servlets can be operating system and hardware platform independent.Servlets process HTTP/HTML requests with all the benefits of the mature Java language (portability, performance, reusability, and crash protection.)
