Laptops
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 talking about laptops, which are also referred to as notebook computers, we actually imply small PCs for mobile 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 rechargeable batteries of laptops get their power from an AC/DC adapter and their capacity enables them to be functional for several hours.
The thin shape of the devices definitely led to their being called notebook computers. Laptops thickness seldom goes higher than 1.5 inches and their overall size specifics range from 10x8 inches (13 inch display) to 15x11 inches (17 inch display) or up. Furthermore, laptops are built light, 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 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 took shape as a project 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 available for public use. 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 the flexible use they are suitable for. 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 accepted world standards for the making of the elements for the peripherals and add-in PC cards in desktop computers, the processor and hard driver manufacturing part does not fall subject to any international regulation yet.
