This refers to the Von Neumann Architecture which is centered on the following four principal components:
Tasks that cannot be accomplished by a computer (Examples)
Some tasks can be easily completed by a computer (sorting lists, searching for information quickly, large calculations) while other tasks cannot (manufacturing a car, making a sandwich, etc.)
Some tasks computers cannot do:
Empathy: It means discerning what another person is thinking and feeling, and responding appropriately. It’s key for organizations looking to create complete and meaningful experiences for customers.
Collaborating: The world is doing ever more of its work in teams. We form, exchange, improve, accept and reject ideas, and we improve our collective performance, through deeply human interpersonal processes that may happen even without our knowing it.
Storytelling: It may not be rational, but we humans find stories more compelling and persuasive than mere facts. Yet we aren’t moved by a story unless we can evaluate the teller, decide whether he or she is trustworthy, and gauge the true passion that he or she brings to it. We didn’t evolve to make that connection with a robot.
Creatively solving problems together: No matter how capable computers become, humans are still in charge of which problems need to get solved, and humans in organizations are constantly revising their ideas of what their problems and goals really are. Success requires group creativity and innovation.
Social media
Websites and applications that enable users to create and share content or to participate in social networking.
Permanence of online data
Nothing you do online is private and anything you put on social media (even if you delete it) could still exist forever and can never be completely erased.
Appropriate methods of communication
When communicating with others, consider the best way to deliver the message (texting, e-mail, social media, in person)
Online safety
Wot? online safety, wot that?
