A laptop (also called a notebook) computer is a portable, lightweight, designed to be transported and used in different places with ease. Usually contains a laptop LCD screen (LCD), keyboard, mouse (usually a touchpad area where you slide your finger), hard drive, ports for connectivity via LAN or fax / modem, CD / DVD We did not have the latest over the entry for solid state hard drive review when there is a need to use one of these connects to an adapter for USB ports.
The term derives from the laptop agglutination of English terms in lap (lap) and top (top) laptop meaning in counterpart to the desktop (in the table).
Laptops can be divided into two categories: portable, appealing especially to those who need a computer as a work tool, but often move about from one place to another, and desktop replacements, aimed at people who want computers with some mobility, and performance similar to a desktop computer.
Laptops are small portable and lightweight, and are designated to do so that your batteries are able to power the laptop for a long period, four to five hours or more). This comes at the cost of other specifications of the laptop, such as RAM (rarely more than 1 GB), video card (rarely more than 128 MB shared), processor speed, rarely exceeding 1.8 GHz, and rarely more than 80 GB of hard drive space. The screens are the most common 14 "(or 14.1" widescreen) and 15 "(or 15.4" widescreen).
Current internal laptop hard drives, on the other hand, are chosen so as to possess good performance comparable to desktop computers (1 GB or more RAM, video card 512 MB dedicated 120 GB or more and up to 2.8 GHz speed processor. Such laptops, geared to those who want performance (for use in demanding applications such as games, for example) are heavy, relatively large (making it difficult to walk), and spend your batteries quickly (which rarely exceeds three hours, can decrease for one hour or less, in the case of large applications.)
Desktop replacements are common between 15 and 17 inches, though some laptops have 19 or even 20 inches. The latter are rarely moved from one place to another or used outside of a facility without taken (for example, in a plane), because they spend their batteries very quickly (rarely more than 1.5 hours), and its weight and size (which, ironically, make it unlikely to use the laptop on top of the neck ), factors that limit their use in places relatively fixed.
Today, many laptops are equipped with wireless network adapters that enable connection to computer networks wireless.
These networks can be installed in office, and it is also very common to find residences. With the sata laptop hard drive, laptop users can access the internet on various outlets such as restaurants and airports without the need of connecting wires, provided that the sites offer the service.
