Notebook
Notebook is a general term for a full-sized laptop, also called the garden-variety laptop. Although notebooks vary in overall size, specifications, processor speed, storage capacity and memory, but a notebook is considered weigh around 5–8 pounds, display from 13 to 16 inches and also portable. They can vary in price from low cost to high-performance productivity equipped with sound cards and very nice graphics for games and multimedia.
Ultrabook
These laptops are thinner like weight around 3 pounds and screen comes at 15 inches, while keyboard is smaller and runs on lower-power processor for long battery life with strong built-in security features.
Ultraportable
These laptops are thin and light, sometimes called subnotebook specially designed for mobility. This type of laptops don’t have built-in CD/DVD drive and less number of connection ports to maintain a super-slim profile.
Netbooks
These laptops are very small and inexpensive, with low-powered Intel Atom processor and very small keyboards. This type of computer is still around, but they have been replaced by tablets, ultrabooks and ultraportable.

Core i3, i5,
and i7 are not processor generations, while these are models of processors.
Following are processor models released by Intel.

2 QuadCore
i3,i5,i7
The theory
of generation comes after the releasing of Core i series. The main difference
in processor generations is, the difference of processor micro-architecture. If
you have an Intel i7–8700k then the first digit is generation number, means you
have 8th generation laptop. Intel has introduced the following
processor generations.
1st
Generation — Nehalem (2010)2nd
