Notebook generally runs on a single main battery and is capable of doing the same tasks as a desktop computer can. It charges the battery and in the meanwhile supplies power to the laptop too. Notebook are less powerful than their desktop counterparts at the same price. This is because of the fact that most parts used in desktop computers are miniaturized to fit into the slim notebook version of the machine. A notebook differs from a desktop PC in terms of power supply, display, and the type of input devices it uses. Notebook processors usually have multiple sleeps, meaning slow down modes which help in increasing battery life and can also run on low voltage.
Notebook computers generally cost more than desktop computers with the same capabilities because they are more difficult to design and manufacture. The most important advantage of a notebook is its portability. One can work with ease anytime and everywhere. Also, access to wireless networking in public places is making notebooks more and more useful.
The first notebook was arguably the GRiD Compass 1101, released in 1982 by Bill Moggridge. It was enclosed in a magnesium case, and could run on batteries. It featured the clamshell design where the flat display folded shut on the keyboard. The first commercially successful notebooks were from the SupersPort series from Zenith Data Systems (ZDS)
Notebooks are the rage of the new generation today. No matter what the purpose one might have for using a notebook, it seems that mobility will always seem to be the main reason for such a product purchase.
