Laptop Computers

By Cathereine Night

Technical inventions arrange the fundamental structure of our modern world. 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 discussing about laptops, which are also referred to as notebook computers, we actually imply small PCs for flexible use.

The typical components of desktop computers are all to be found in laptops. 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 lineament specific to laptops, but the recharging mode is carried out through an AC/DC adapter that allows extensive functionality.

The very name of notebooks comes from the thin shape and small size of these computers. Laptops thickness seldom goes higher than 1.5 inches and their overall sizing specifics range from 10x8 inches (13 inch display) to 15x11 inches (17 inch display) or up. Furthermore, they are not heavy, weighing between Iii and 12 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 that the laptops invention germs were there. The person who imagined this was Alan Kay of Xerox PARC. In 1972 took shape as a project 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. Moreover, laptops allow work continuation in case of accidental power outages.

Laptops are also more economical and do not produce as much heat as desktop computers do. Compatibility and standardization are the main flaws of laptops today. In spite of some international standards for the manufacturing the elements for the peripherals and add-in PC cards in backcloth computers, the internal components are a lot more difficult to standardize according to a unique international code.
