The history of the computer can be traced back to the year 1642, when French mathematician and scientist Blaise Pascal invented the Pascaline. Back then, it was considered a revolutionary invention, but it only featured one function, which is to do addition and nothing else. Thanks to the rapid development of technology, computers today can do lots of different things and they are available in many different sizes. Nowadays, almost everyone has a laptop or notebook computer. However, a lot of people can't tell the difference between a laptop and a notebook.
A notebook is slightly different from a laptop in some aspects. It is usually equipped with a long life battery that can last up to 4 or 5 hours, so you can use it for a longer period of time. It is also very light and thin. Generally a notebook computer has a 12-14 inch TFT screen and it does not have internal DVD/CD drivers. However, it usually comes with an external DVD driver. It is also generally more expensive than a laptop; it gets more expensive if it is thinner and lighter. There are so many brands that offer various models of notebooks with different storage capacities and processor speeds. If you would like to find one that suits your needs, it is always better to read notebook computer reviews from reliable sources. Thus, it will give you an insight into whether the particular notebook is what you need.
On the other hand, a laptop computer is a type of portable computer that is generally bigger and heavier than a notebook computer. It only has 2-3 hours of battery life and it features a 14-17 inch widescreen TFT display. The good thing about laptop compared to notebook is that it comes with an internal DVD-ROM or DVD-RW driver, so you do not need to purchase an external driver to play your movie DVDs. Furthermore, a laptop is also upgradeable. You can easily replace your old RAM card with a new and better one to improve the performance of your laptop.
These days, you can even buy a netbook computer. A netbook is much smaller and lighter than a notebook and laptop. The battery can last up to 8 hours and it comes with a 8-10 inch screen. Since it is equipped with a less powerful processor, you can't really use a netbook computer for multitasking or for entertainment purposes. It generally doesn't come with an internal or external DVD driver, so you will need to purchase a separate external unit. This portable computer is recommended for those who are always on the go and need access to a computer frequently. More Articles about Computer
