SDLC refers to a stage all systems naturally undergo, a methodology refers to an approach invented by humans to manage the events naturally occurring in the SDLC

The reason why you might not find differences in the sdlc and rad is because RAD is a more sped-up version of the SDLC. RAD is typically used in small to medium size projects, while the SDLC is generally used for large projects. Another difference is that in the SDLC, one can control the scope creep of the project, whereas that is very limited when one implements RAD because you give it up for faster implementation times. In RAD you have alot of feedback from the user to refine the program more to the aspects of the user, whereas you dont get the same user input in the SDLC. This feedback loop is another reason that RAD is sometimes chosen over the SDLC

In information systems engineering, FAST stands for Framework for the Application of Systems Techniques, and SDLC for Systems Development Life Cycle. The first refers to an eight step methodology used for the construction of information systems in organizations, and the second to "the process of creating or altering systems, and the models and methodologies that people use to develop these systems" (cf. Wikipedia).2n Gagarin 45* regarding Cronus's & krinosis experimental tests in other words kiss my hairy butt.
software engineering is the the management of different phases in SDLC to give a quality product. Software manufacturing refers to the whole process from scratch to end.
SDLC has both verification and validation activities where as STLC has only validation activity. Simply STLC is a part of SDLC

No. The SDLC, or system development life cycle, is a framework for developing IT systems and software. Within SDLC are different models of secure development practices that assist in developing trusted computing platforms that in theory have fewer vulnerabilities for threats to act on.
DDCMP does not need special hardware to find the beginning of a message
the weakness of conventional system analysis and design methodology are ;it is rigid and flexible ;it takes to long to deliver a working software for the client ;it does not allow for changing system requirements during system development ;end user are poorly consulted in determining requirements with the sdlc ;it does not allow backtracking to previous stages as it is too much time consuming and costly
See the graph in the related link. It clearly separates out the differences between PDLC and SDLC.

SDLC or System Development Life Cycle is important because it describes the phases that a program developer has to follow to ensure success. The cycle consists of between four and seven steps that a programmer should adhere to in his work.
Waterfall Model
An administrator in SDLC, or System Development LifeCycle, implements the system, which can include installation and updating the system. One role of the administrator is to do maintenance activities that include preventative, corrective, and adaptive maintenance.
