Technical inventions represent the fundamental structure of our modern world. We seem to be unable to do anything without technology. One of the inventions many of us cannot do without is the PC. The latest developments in the field of computers have brought us the laptops. When talking about laptops, which are also referred to as notebook computers, we actually mean small PCs for mobile use.
We can virtually retrieve all the basic components in laptops from desktops. 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 thin shape of the devices definitely led to their being called notebook computers. Laptops thickness seldom goes higher than 1.5 inches and their dimensions 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. The design of most laptops as the flip form factor, is meant to protect the screen of the computer when it is closed.
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 commercially available. 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 good bit about laptops is evidently their portability. 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. Despite of some international 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.
