A Notebook or commonly referred to as a laptop computer is a smaller version of the desktop computer. But its advantages are that all of its components it comes in one neat mobile notebook shaped digital display box, and is easily portable. It usually weighs around 2 to 17 pounds ( 1 to 8 kgs ) depending on the make, materials and different other factors that come into play such as the parent company etc.
Notebooks run on a singular battery from ( usually ) an external AC / DC adapter. It charges the battery and in the meanwhile supplies power to the laptop too. Numerous `notebooks` have a 3 volt back - up cell to supply power during power failures and when in places where there is no steady power supply. Notebooks, as personal computers are worthy and capable of doing the same work as of desktop computers. But they 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.
Notebooks usually have LCD ( liquid crystal displays ) and they use separate memory modules for their RAM. Notebooks usually have a touchpad ( or trackpad ) for a mouse and an in - built keyboard. But external installments of these can also be attached if the user wants to do so.
