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 called 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 include the display, the keyboard, a pointing device - touchpad or pointing stick, and the battery.
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 very name of notebooks comes from the thin shape and small size of these computers. Laptops are usually 0.7 - 1.5 inches thick and their dimensions range from 10x8 inches (13 inch display) to 15x11 inches (17 inch display) or up. Furthermore, laptops are built light, weighing between Tercet 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 this 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 gained a lot in terms of proficiency.
Unfortunately, besides the obvious advantages of laptops, there are also some disadvantages. 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.
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. Despite of some accepted world standards for the making of the elements for the peripherals and add-in PC cards in setting computers, the internal components are a lot more difficult to standardize according to a unique international code.
