Small Notebook Computers
June 2nd, 2010
Technical inventions represent the fundamental structure of our modern world. 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 talking about laptops, which are also referred to as small notebook computers, we actually mean small PCs for flexible 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 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 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 overall size specifics range from 10×8 inches (13 inch display) to 15×11 inches (17 inch display) or up. Furthermore, laptops are built light, 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 were produced for the first time 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. 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, 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. In addition, laptops allow work continuation in case of accidental power outages. Furthermore, the cheapest laptop computer will is mre econmical and will use less electricity and generate a lower amount of heat as compared to desktops. Compatibility and standardization are the main flaws of laptops today. In spite 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.
