The laptop notebook computer is a mobile computer that is small enough to be transported to and held on the lap while I work. It weighs no more than 1 to 6 kg. It is much smaller than its predecessor - the desktop computer. A laptop has the same features as the desktop one and therefore the parts are equal, but the mini format. Instead of a mouse to a touchpad but it works on the follow-up request, a mouse can be connected. Internet tablets are used for the vital interspaceLink.
The laptops have good and bad points. Due to the technical and economic hurdles the unit can not easily be updated. With regard to health issues, the laptop is responsible for low sperm count, since it is constantly on the scrotum that causes the heat required to rise to undesirable levels in this region of the body. In order to prevent the mobile unit can stand on your desk and do not necessarily held on the lap the whole time.
Another obvious problem is that laptops can easilystolen. Laptops are relatively slowly and are less sound and graphics capability. Laptops are much more expensive than desktops, but includes the last time the gap. However, laptops consume less power. The performance is more or less the same as the desktop models and models of new generation are becoming more efficient and user-friendly.
How can such a small package hold these various options?
Laptops and desktops on the same principles, but the difference is how the components aremounted and fixed. In a desktop there are motherboard, video card, hard disk, etc. The monitor, keyboard and other ancillary products, without wires or cables connected, but there is plenty of room for additional cards, cables while a good air flow. In a laptop screen and keyboard based on the side of the box. The design of the laptop is small and flat, with all the parts fit snugly into. Thus, the space is compact allows for the preservation of power and lessProduction of heat.
The CPU is the brain of the computer and a fan and heatsink with plates and channels are needed to cool it. But a laptop is running on a lower voltage, the less speed. Instead of using pins and sockets, as in a desktop, a laptop balls. However, this means that the processor will be removed independently. The batteries of laptop computers that run fast run down today suffer more often. The Apple G4 processor tries to neutralize themDefect.
Mini-laptops, great fans, heat spreaders and heat sinks. Some use to keep the coolant temperature. The CPU's of the laptop are on the edge of the box allows for hot air is able to be released without running over other components. A laptop also has a hard disk is where the operating system, data and program files.
The mechanism of memory is different from a laptop model to another. In general, smaller memoryModules are used to save space. Both work with electricity, but a laptop can work on batteries.
Every invention begins with a dream. Had in 1970 Alan Kay of Xerox as a vision of a portable computer about the size of a notebook. He never went far ahead with the idea, but you put the balls roll. In 1979, the first working portable computer was made by William Moggridge of Grid Systems. Others, like Apple's soon jumped into the complete success story.
