SDLC has both verification and validation activities where as STLC has only validation activity. Simply STLC is a part of SDLC

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 Software Development Life Cycle (SDLC) focuses on the process of designing, developing, testing, and deploying software. It includes phases like planning, design, coding, testing, and maintenance. The Software Testing Life Cycle (STLC), on the other hand, is specifically concerned with the process of testing software to ensure quality and functionality. It includes phases such as requirement analysis, test planning, test design, test execution, and defect reporting. While SDLC encompasses the entire software development process, STLC is a subset that focuses exclusively on testing to identify and fix issues in the software.
See the graph in the related link. It clearly separates out the differences between PDLC and 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
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 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.
There are usually two design stages in SDLC. They are:High-level Design &Low-level Design

Actually - all phases of SDLC can be a source for Errors. The later in the life cycle an error is detected, the costlier it will be to fix it
