A notebook computer is a term used interchangeably with laptop computers. For those of you not familiar, a notebook computer is one that is smaller and lighter than a personal computer. You can take it with you anywhere so it offers you more access to the internet, a way to watch movies, and even a way to work while you are away on business trips.
The first notebook computer was introduced in 1981 but they were very expensive and not as versatile as they are today. IBM and Epsom both placed versions of portable laptops on the market in 1983. Even with more models emerging, notebook computers were an item often associated only with high profile businessmen. For more info see notebooks computer
