What is the difference between a desktop computer, a  laptop computer and a notebook computer?

The main difference between a desktop computer and a notebook computer is the size and shape.

Desktop computers are much bigger and heavier than laptops and notebooks.  They usually store more information and have more features than the other computer types.  This being said, they are usually left at home and are not for quick transport.  Also, desktop computers usually have all of their parts in different pieces.  the main “brain” of the computer is linked to the screen, power source (it has no battery) and keyboard/mouse through wires.  While desktops are bigger and not portable, many find them to be faster and easier to work with.

Laptop computers are designed for on the go travel.  While they can be used as home computers, laptops are fitted with batteries and can be transported easily from one place to another.  Laptops and notebooks are usually confused as the same thing.  While they both are designed for travel, the laptop usually has graphics cards, CD writer drives, and larger (usually heavier) screens.  A big question to consider when buying a computer is whether you should have a laptop or a notebook.  Read more...
