What does the term "dispatch" and "virtual" mean in the documentation?

So then in Kotlin, are all open functions “virtual” functions? Is it correct to say that

• functions in normal classes with open inheritance modifier
• functions defined in interfaces
• functions defined abstract classes

are all “virtual”? (all members of interfaces or abstract classes are implicitly open , or am I wrong?)

If I rephrase this again, the “virtual”(overridable) members would be among the following

• members(functions or properties) in normal classes with open inheritance modifier (members are either final(default) or open; abstract members are not allowed)
• members in interfaces (members are either open or abstract, depending on the existence of implementation; final members are not allowed)
• members in abstract classes with open or abstract modifiers (members are final(default) or open or abstract)

Is this correct?
