Introduction to Software Technologies
Basically nosotros accept iii types of Software,
i) System Software: Used to operating the organisation in addition to its devices...
Ex: OS (Windows, UNIX etc...), Device Drivers....
ii) Programming Software: Used to prepare the Software Applications.
Ex: Java, .NET, Oracle, SAP etc...
iii) Application Software: Used to deport Business Operations.
Ex: Banking Applications, Insurance Applications, ERP Applications, Ecommerece Applications etc...
------------------------------------------
1) What is Unix?
UNIX is an operating organisation which was starting fourth dimension developed inward the 1960s, in addition to has been nether constant evolution e'er since. By operating system, nosotros hateful the suite of programs which brand the reckoner work. It is a stable, multi-user, multi-tasking organisation for servers, desktops in addition to laptops.
UNIX systems likewise accept a graphical user interface (GUI) similar to Microsoft Windows which provides an slow to purpose environment. However, noesis of UNIX is required for operations which aren't covered past times a graphical program, or for when in that location is no windows interface available, for example, inward a telnet session.
There are many dissimilar versions of UNIX, although they part mutual similarities. The most pop varieties of UNIX are Sunday Solaris, GNU/Linux, in addition to MacOS X.
2) What is C?
The C programming linguistic communication is a construction oriented programming language, developed at Bell Laboratories inward 1972.
The C programming linguistic communication is used for developing,

3) What is C++?
C++ is an object-oriented programming (OOP) linguistic communication that is viewed past times many equally the best linguistic communication for creating large-scale applications. C++ is a superset of the C language.
A related programming language, Java, is based on C++ but optimized for the distribution of programme objects inward a network such equally the Internet. Java is somewhat simpler in addition to easier to larn than C++ in addition to has characteristics that plough over it other advantages over C++. However, both languages require a considerable total of study.
4) What is Java?

Games Etc...
5) What is .NET?
The .Net framework is a software evolution platform developed past times Microsoft. The framework was meant to exercise applications, which would run on the Windows Platform.
The .Net framework tin flame survive used to exercise both - Form based in addition to Web based applications. Web services tin flame likewise survive developed using the .Net framework.
The framework likewise supports diverse programming languages such equally Visual Basic in addition to C#. So developers tin flame guide in addition to select the linguistic communication to prepare the required application.
6) What is SQL?
> SQL stands for Structured Query Language
> SQL was initially developed at IBM inward 1970s
> SQL is the criterion linguistic communication to communicate amongst relational database administration systems similar Oracle, MS Access, MS SQL Server, MySQL, DB2, Sybase Etc...

vii. SQL is used to execute queries against a Database
viii. SQL tin flame prepare permissions on tables, procedures in addition to views
ix. SQL is used to Create stored procedures inward a Database
x. SQL is used to Create views inward a Database
7) What is SQL Server?
Microsoft SQL Server is a relational database administration organisation developed past times Microsoft. As a database server, it is a software production amongst the original business office of storing in addition to retrieving information equally requested past times other software applications—which may run either on the same reckoner or on approximately other reckoner across a network (including the Internet).
8) What is Oracle?
Oracle database is a relational database administration system. It is known equally Oracle database, OracleDB or but Oracle. It is produced in addition to marketed past times Oracle Corporation.
Oracle database is the starting fourth dimension database designed for company grid computing. The company grid computing provides the most flexible in addition to toll effective agency to contend information in addition to applications.
9) What is Python?
Python is an interpreted, object-oriented programming linguistic communication similar to PERL, that has gained popularity because of its clear syntax in addition to readability. Python is said to survive relatively slow to larn in addition to portable, important its statements tin flame survive interpreted inward a lay out of operating systems, including UNIX-based systems, Mac OS, MS-DOS, OS/2, in addition to diverse versions of Microsoft Windows.
10) What is ?
Testing reckoner Software in addition to or Mobile Software is called ,
tin flame survive done inward 2 ways,
i. Manual Testing: Testing Computer in addition to or Mobile Software manually without using whatever Test Tool or Test Script....
ii. Automated Testing or Test Automation: Testing Computer in addition to or Mobile Software using whatever Test Tool or Test Script...
11) What is SAP?
SAP stands for Systems Applications in addition to Products inward Data Processing.
SAP past times Definition is likewise named of the ERP (Enterprise Resource Planning) software equally good the mention of the company.
