Software architecture is the top-level organizing philosophy for how a program's code is structured to solve its overall problem, sitting above lower-level concerns of specific syntax/algorithm choices and above the middle layer of design principles and design patterns (e.g., strategy, observer, coupling reduction, single responsibility). Model-View-Controller (MVC) is a specific software architecture that divides an application into a model (the data), a view (a presentation of the model in a particular format), and a controller (the logic binding model and view together and mediating user interaction). This is a concept within software engineering/software design, distinguishing architecture-level organization (the overarching structural approach) from the design-pattern layer and the low-level implementation-choice layer, all three of which jointly determine code quality.
