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. The latest developments in the field of computers have brought us the notebook computers. When discussing about laptops, which are also referred to as portable pc laptop computers, we actually mean small PCs for mobile use.

We can virtually retrieve all the basic components in laptops from desktops. Thus, laptops have a display screen, a built in keyboard, a pointing device replacing the mouse and a battery power source. The difference lies in the fact that all these components are to be found into one single unit that is also portable. The batteries are the main distinction and individual feature specific to laptops, but the recharging mode is carried out through an AC/DC adapter that allows extensive functionality.

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 dimensions 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. 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 the transformation was Alan Kay of Xerox PARC. In 1972 he put his idea on paper 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 available for public use. Since then laptops have developed and become more and more proficient and skyrocketing laptop sales.

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 their portability. Moreover, laptops have the ability to work on battery power in the event of a power outage. Oftentimes the first class laptop pc computer uses less electricity and generates a lower amount of heat as compared to desktops. Compatibility and standardization are the main flaws of laptops today. Despite of some accepted world standards for the manufacturing 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.
