3. What is Software engineering?
 Software engineering is the process of analyzing
user needs and then designing, constructing, and
testing end user applications that will satisfy
these needs through the use of software
programming languages.
 It is the application of engineering principles to
software development such as Finding Malware,
Language, Script, Application, download, Update,
Network and Install.
 The formal definitions of software engineering
are: Simple, Quantifiable, Disciplined,

4. Application on Daily uses:
 System Software:A collection of programs written to service other programs.
Compiler, device driver, editors, file management.
 Application software:It solves a specific Business needs. It is needed to
convert the business function in real time.
 Embedded Software: There are software control systems that control
and manage hardware devices.
 Web application: It is also called " web apps ", are evolving into
sophisticated computing environment and content to end user database.

5.  Artificial intelligence software:This include- robotic, expert system, pattern
recognition, image and voice, artificial neural network, game playing, theorem
proving ... It solves Complex problems.(Most in demand and efficient
Software)

6. Importance of Software engineering:
 Software Design is the process of defining software methods, functions,
objects, and the overall structure and interaction of your code so that the
resulting functionality will satisfy your users requirements.
 Software engineering is important because specific software is needed in almost every
industry, in every business, and for every function.
 Software engineers should understand how to work with several common
computer languages, including Visual Basic, Python, Java, C, and C++.
 Software engineering almost always includes a vast amount of teamwork.
Designers, writers, coders, testers, various team members, and the entire IT
team need to understand the code.

7. Key Factor influencing Software engineering:

8.  Flexibility is the ability of software to
add/modify/remove functionality without damaging
the current system.
 Extensibility is the ability of software to add
functionality without damaging system, so it may be
thought of as a subset of flexibility.
 Change is inevitable in software development and so,
this is one of the most important properties of quality
software.
Flexibility And Extensibility:

9. Maintability and Readability:
 Maintainability is a little similar with flexibility
but it focuses on modifications about error
corrections and minor function modifications.
 It can be supported with useful interface
definitions, documentation, and self-
documenting code.
 The more correct and useful documentation
exists, the more maintainability can be
performed.

10. Performance and Scalability:
 A scalable system responds user actions in an
acceptable amount of time, even if load
increases.
 The hardware may be added for handling
increasing user transaction, but the architecture
should not change while doing this. This is
called vertical scalability.
 Ability of running on multiple, increasing count
of machines is multiple processing. If the
software can perform that type of processing,
this is called horizontal scalability.

11. Software Security:
 Security is a very important issue on
software development, especially for web or
mobile based ones which may have millions
of users with the ability of remote accessing
to system.
 This may include authorization and
authentication techniques, network attack
protections, data encryption.
 All possible types of security leaks should be
considered, otherwise one day only one
attack may crash your whole application and

12. Conclusion:
 Software engineering continues to prove very essential to our daily lives.
There are so many distinct features that make a good software engineer.
 There are various success factors that guarantee a successful software
development project.
 Software engineering values are what every software engineer must learn to produce
high-quality software. A requirements specification must completely define the tasks
that are to be performed by the program successfully
