cohesion

The degree to which the elements inside a module belong together. Cohesion refers to the degree to which the elements of a module/class belong together, it is suggested that the related code should be close to each other, so we should strive for high cohesion and bind all related code together as close as possible. It has to do with the elements within the module/class.

coupling

The degree to which a class or module is connected to other classes or modules. Coupling refers to the degree to which the different modules/classes depend on each other, it is suggested that all modules should be independent as far as possible, that’s why low coupling. It has to do with the elements among different modules/classes.

OO

Object Oriented

SoC

Separation of Concerns, a design principle for separating a computer program into distinct sections, such that each section addresses a separate concern.
