A laptop is a type of personal computer that stands out for its mobility.

In practice, this corresponds to the following three qualities: compact size, low weight, at least carries all the MAIN computer hardware components which form a single block.

Types

There are various types of laptops that have emerged over the decades. In general, the smaller the size of the computer matches the functionality and performance.

The larger laptops are the size of a suitcase of medium size. Other types of laptops are characterized by lower average size:

  • laptop computers;
  • notebook computers;
  • tablet computers;
  • handheld computer.

The laptop computer is suitable while you sit or recline and hold it in your lap. In practice, this corresponds to the following two characteristics: all the major hardware components of computers form a single block even while the computer is being used.

Modern notebook

The notebook computer is a subtype of laptop computer which is characterized by two hardware blocks of similar size and connected together by one or more hinges that allow the superposition.

In particular, when the computer is not in use, the two blocks can be stacked to save space and facilitate mobility.

When using the computer, you must remove the two blocks instead. In fact, the upper block features the display, the lower block, the keyboard (respectively the main user interface output and the main user interface for input of the notebook computer).

And only two blocks away the display and the keyboard can be used. An additional benefit that is obtained by superimposing the two blocks is to protect the display and keypad: two components of the computer particularly delicate.

Usually the laptops are powered by a rechargeable battery (lithium, in the latest models). Its relatively high cost is determined by the electronic components that compose it.

They, even if similar to those of a desktop, are miniaturized and optimized for a lower energy consumption. Generally the integrated peripherals are numerous, these include a webcam, memory card reader, Wi-Fi router and so on.

One of the most significant characteristics of the laptop is the weight which is influenced by:

screen size;
type of battery installed;
presence of internal components (eg CD drive, hard drive, etc.).
power supply;
material with which it is assembled (plastic or magnesium).

A particular family of laptops is represented by the Tablet PC, or laptop screen on which the user can write with a pen in hand, as if it were made of paper. Some Dell tablet pc (such as the Dell Latitude XT) and HP also have multi-touch functionality.

Benefits

The first benefit you will notice buying a laptop is the convenience of transport. The advanced power-saving technologies allow a decent battery life, allowing use of computers in special situations where you cannot connect to the mains, use at construction sites, etc..

Another convenience is also about the smallest footprint, and generally also have lower noise levels.

The performances is very similar to those of a desktop PC with the same hardware configuration, and thanks to the spread of USB, you can connect any device that complies with the USB standard, including through the use of specific HUB.

The prices have dropped significantly in recent years, this allows you to find many models and brands in large commercial distributions; worth mentioning that in the third quarter of 2008, worldwide sales of laptops have surpassed those of desktop PCs.

The newer models and belonging to the higher end use for data storage in place of traditional magnetic hard drives, solid state drives (SSD), allowing faster data access, quiet, and reduce fuel consumption, heat and noise.

Disadvantages of using a laptop

Compared to a traditional desktop PC, the main disadvantage of a laptop covers limited ability to replace components to increase performance (such as the video card) and in case of failure the difficulty of finding spare parts specific to the model or series, such as DVD player or monitor.

These constraints often force the purchase of a new model, forcing consumers to a greater outlay.

In addition, the production companies of the various notebooks and graphics cards have failed to create an internal connection in your notebook so you can replace the CPU with another more powerful model with ease.

Regarding the use of the laptop at fixed locations and for longer periods of use, we do not recommend this unit for the uncomfortable position for work due to the specific geometry of the device.
