Question Laptop vs. Notebook vs. Ultrabooks

[Nintendo_Boy1996]

I want to know what is the difference between a Laptop, a Notebook, and Ultrabook. I know a Netbook and is a type of laptop the focus more on internet based activity. A type of Netbook is any laptop that is running Chrome OS. I thought a laptop and notebook are the same thing. Would a Mac Book Pro/Air be consider an Ultrabook?

Laptop and notebook are effectively interchangeable. There's some historical differences between them, but they largely don't matter.

Ultrabook is a marketing trademark by Intel, but it generally refers to portable computers that are as thin (generally less than 0.8"), lightweight (generally <5 lbs / 2kg), and have longer battery life than mainstream laptops.
