By Cathereine Night | December 16, 2008
Technical inventions represent 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.
So far laptops and notebooks are the up-to-the-minute achievements in the field of computers, and they are undeniably conquering more users every day. When talking about laptops, which are also called notebook computers, we actually mean 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 feature article 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 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 were produced for the first time 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 took shape as a project under the name of Dynabook.
By 1981, the first laptops were introduced on the market. The Epson HX-20 and Osborne 1 models 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 advantage of laptops is evidently the flexible use they are suitable for. In addition, laptops allow work continuation in case of accidental power outages.
Furthermore, laptops use less electricity and generate a lower amount of heat as compared to desktops. The disadvantages of laptops come from the standardization and compatibility issues. Despite of some international standards for the manufacturing the elements for the peripherals and add-in PC cards in play down computers, the internal components are a lot more difficult to standardize according to a unique international code.
