The laptop is a portable notebook computer that is small enough to be removed and stored in the lap while working. It does not weigh more than 1 to 6 kg. And 'much smaller than her older sister - the desktops. A laptop computer has the same features of a desktop, and then the components are the same but of mini size. Instead of a mouse, a touchpad, the tracking but if required a mouse can be connected. Internet tablets are used for the vital interspace link.
L 'laptops have both good and bad points. Because of technical and economic obstacles, the unit can not be easily updated. As regards health, the laptop is due to a low sperm count because it is constantly on the scrotum that causes the heat to rise to unwanted in this region of the body. To prevent the mobile unit can be kept on the desk and do not necessarily have to be held in her arms all the time.
Another obvious problem is that the laptops can be easily stolen.Laptops are relatively slow and are less sound and graphics. Laptops are much more expensive than desktops, but recently the gap is closing. However, laptops use less energy. Performance is more or less the same as desktop models and models of new generation are more efficient and easy to use.
How can a small package in possession of such options?
Laptops and desktops running on the same principles, but the difference is how the pieces are assembled and established. In a desktop there are motherboard, video card, hard disk, etc. monitor, keyboard and other accessories are connected without wires or cables, but there is not enough space for additional cards, cables, while providing for airflow . In a laptop screen and keyboard according to the side of the box. The design of the handset is small and flat, with all the pieces fit together precisely. So space is compact and allows the preservation of power and produce less> Heat.
The CPU is the brain of a computer system with a heat sink and fan plates and channels are needed to cool it. But a laptop running on a lower voltage and therefore lower speeds. Instead of plug and socket as a desktop, a laptop balls are used. But it means that the processor can not be removed separately. Batteries for laptops that are likely to run often run down. The Apple G4 processor attempts to counteract this defect.
Laptopsuse miniature fans, heat sinks and heat sinks. Some use liquid cooling to maintain temperature. The CPU `s notebooks are located on the edge of the box that the hot air flows to be released without other components. A laptop computer has a hard disk where the operating system, data and program files.
The mechanism of memory will vary from one model to another laptop. Memory modules are usually smaller than used to reducespace. Both run on electricity, but a laptop can run on batteries.
Every invention begins with a dream. In 1970 Alan Kay of Xerox had a vision of a portable computer the size of a notebook. He had never gone forward with the idea, but set the ball rolling. In 1979, the first notebook of work was done by William Moggridge of Grid systems. Others, like Apple will soon jump in the history of complete success.
