2. 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.

3. Linux - free
software
Free 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.

4. Difference Windows
& Linux
Linux:
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.

5. 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.

6. CreatingTable by
Oracle
1.Oracle create table syntax defines
the table name
2.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;

7. 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.

8. 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.

9. 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”.

10. 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.

11. 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.

12. 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.

13. 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.)
