The modern world is practically based on and composed of a lot of technological inventions. Technology remains basic and we seem to be lost without it. A clear example of the technical addiction is the use of the PC.

The latest developments in the field of computers have brought us the laptops. When talking about laptops, which are also referred to as notebook computers, we actually mean small PCs for mobile use.

We can virtually retrieve all the basic components in laptops from desktops. Thus, laptops have a display screen, a built in keyboard, a pointing device replacing the mouse and a battery power source.

The advantage of laptops is that they make one single unit that comprises all the other items, allowing for easy maneuvers and lots of mobility. The batteries are the main distinction and individual characteristic specific to laptops, but the recharging mode is carried out through an AC/DC adapter that allows extensive functionality.

The thin shape of the devices definitely led to their being called notebook computers. Laptops are usually 0.7 ? 1.5 inches thick and their overall size of it specifics range from 10×8 inches (13 inch display) to 15×11 inches (17 inch display) or up. Furthermore, they are not heavy, weighing no more than twelve pounds.

Last but not least, the flipping feature allows for a good protection of the screen and makes portability possible.

Personal computers became feasible at the beginning of the 1970s and not long after those years the idea of portable PCs ? laptops, appeared. The person who imagined the transformation was Alan Kay of Xerox PARC. In 1972 he put his idea on paper under the name of Dynabook.

By 1981, the first laptops were introduced on the market. The Osborne 1 and then, in the same year, the Epson HX-20 were the first portable computers commercially available. Since then laptops have developed and become more and more proficient.

Unfortunately, there are downsides to the use of laptops too. First we need to see the good parts to be able to investigate the flaws. The main and most important good bit about laptops is evidently their portability. In addition, laptops have the ability to work on battery power in the event of a power outage.

Laptops are also more economical and do not produce as much heat as desktop computers do. The disadvantages of laptops come from the standardization and compatibility issues. In spite of some international standards for the manufacturing the elements for the peripherals and add-in PC cards in screen background computers, the internal components are a lot more difficult to standardize according to a unique outside(a) code.
