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. One of the inventions many of us cannot do without is the PC. So far laptops and notebooks are the latest achievements in the field of computers, and they are undeniably conquering more users every day. When discussing about laptops, which are also referred to as 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 include the display, the keyboard, a pointing device – touchpad or pointing stick, and the battery. The difference lies in the fact that all these components are to be found into one single unit that is also portable. The rechargeable batteries of laptops get their power from an AC/DC adapter and their capacity enables them to be functional for several hours.
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 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 between 3 and 12 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 that the laptops invention germs were there. 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. The first laptops were available on the market only in 1981. 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. Moreover, 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. Compatibility and standardization are the main flaws of laptops today. In spite of some accepted world standards for the making of the elements for the peripherals and add-in PC cards in desktop computers, the internal components are a lot more difficult to standardize according to a unique international code.
