The major benefit of a laptop computer vs. a desktop computer is its mobility as well as its abridged size. On the other hand, the cost is normally higher for a little less performance and the laptop’s hardware configuration is much less adjustable, even though it is possible to add additional exterior peripherals thanks to its many I/O ports. Therefore, the inspiration for purchasing a laptop computer has to be above all being a requirement for mobility or required to save space.

Furthermore, with the appearance of networks, and WiFi in particular, it is attractive and extremely easy to connect to the Internet in public Hot-Spots or just in any room of your home as long as it is prepared with a Wi-Fi router. For sophisticated multimedia uses (e.g. connecting a digital camera or an mp3 player, digital video manipulation etc.) the option must fall on the computer’s capabilities (together graphic as well as processor power) and in the type and number of Input/output ports that are accessible.

The processors represent the computer’s brain in that it processes the instruction. Its implementation speed depends on its frequency (in MHz), but two processors from dissimilar brands that have extremely dissimilar frequencies can do equally well. Even while a processor’s frequencies are still necessary criteria to choose a laptop computer, nowadays is preferable to compare the capabilities of all the components (memory, graphics card etc.) over just the processor’s speed. What is more, the amount of random access memory (RAM) can have a substantial result on performance, particularly when it comes to multimedia use. In adding up to the quantity of memory, it is also important to pay attention to its operational speed, which correspond to the speed that the majority of the peripherals will run on.

The screen is distinguished by its size, which is uttered in inches (an inch has 2.54 cm) and correspond to the screen’s slanting length. Unlike screens with cathode ray tubes (CRT screens), the slanting length of a flat screen correspond to the effectual display area. Moreover, allowing for the liquid crystal based technology used in flat screens, the screen superiority of a flat screen can be defined by the time, which is the duration of time needed to turn a pixel from white to black and then black to white. The display arrangement is normally 4:3 (i.e. 3 units high to 4 units wide), but there are more exotic laptop formats that are close to 16:9, such as 15:10, which is modified to screening video sequences (e.g. watching DVDs).

A laptop graphics card is included, and it has a specific graphics chipset that is attached in the motherboard. It is not possible to modify it once the laptop has been purchased. Therefore, if the laptop will be used for graphics applications (video visualization or video games, manipulation 3D applications, etc.), it is a good idea to choose a top-of-the-line graphics chipset. Most systems are fine with what they are manufactured with.  If you need something else it may well be a special order.
