This site contains information about "SDLC". "SDLC" stands for "System Development Life Cycle". This site I have made especially for class 12 students(in the context of Nepal). But Do not think that it is not for you. It is also for you. You can learn or explore your knowledge from here.
In computer field we develop many software; to develop a qualitative software, mostly we apply some steps. As we follow these steps the development goes on being easy for us. Later as it becomes complex, then using this technique we can easily change in different part of programs.
SDLC is a process in which we go for several phases in different cycles. This cycling brings us a different version with numerous features in our software. Making a software is a complex task and takes several months time. We work in a team with different work load to different team member. This "dividing and conquering" process is used in most of the companies.
You can know/understand here about this and can get answer of questions:
q1) What is System?
q2) What differences are there between "computerized system" and "Manual system" ?
q3) How do we go for development of an "Information System/Computerized system"?
q4) What are the models for this?
q5) Who is System analyst and what are his/her roles?
q6) What are the phases applied in software development?
q6.1) What is system design?
q6.2)What is System development?
q6.3)What is Testing?
q6.4)What is Implementation,Evaluation and Documentation?
etc.
