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.
There are number of SDLC models in software engineering. Using life cycle model we can divide the work in different phases thus making it easy and convenient .
What is SDLC?A software cycle deals with various parts and phases from planning to testing and deploying. All these activities are carried out in different ways, as per the needs. Each way is known as a Software Development Lifecycle Model (SDLC)What are the different SDLC Models ?1.Rapid application development(RAD) (including methods like SCRUM, Agile & Extreme Programming);2.The linear or waterfall model(which was the original SDLC method);3.Joint application development (JAD);4.The iterative model;5.The v-model;6.The prototyping model;7.The fountain model;8.The spiral model;9.Build and fix;10.synchronize-and-stabilize
SDLC has both verification and validation activities where as STLC has only validation activity. Simply STLC is a part of SDLC

Software and traditional engineering are somewhat very closely related. Engineering practices like cost and effort estimation are common in both.
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
There are usually two design stages in SDLC. They are:High-level Design &Low-level Design
